fortran常见错误
FAQ之常见错误2014-02-02 13:45:35 来源：Fcode研讨团队评论：2点击：4419本文从编译错误，链接错误，运行时错误，计算结果错误等四个方面介绍了常见的错误及解决思路。
适合初学者阅读。
首先应该明确：错误有哪几种？我们当前遇到的是何种错误？阐述这些问题前，我们先讨论一下常规的应用程序开发的过程：1>>编写代码，使用一个或多个源代码文件。
2>>对第一步的每一个源代码文件执行编译操作。
得到一个或若干个目标代码。
3>>将目标代码，运行时库（Run-time Library）和其他使用到的函数库链接起来。
得到一个可执行文件（EXE 或其他）4>>编写程序的说明书，必要的（输入）数据文件5>>将上述得到的结果发布给用户。
（发布的方式可以是刻录成光盘，销售，放在网站上供别人下载，或者其他）6>>用户得到程序后，运行，输入数据，得到计算结果。
对于很多 Fortran 程序员来说，可能用户就是自己，也可能仅仅是自己教研室的同事同学。
所以第4，5，6步骤很多时候不明显。
而如果使用集成开发环境（IDE）进行开发，第1，2，3步骤又可以一键完成。
因此，很多初学者就认为，写程序就是：输入代码，运行，得到结果。
这样的理解太狭义。
不管我们面对什么使用者来写代码，程序开发应该是上述的过程。
我们的编译器，编译环境，也是为这个过程而设计的。
于是，我们将错误分为四种：一. 编译错误（发生在第2步）编译错误，一般是源代码书写格式不正确，不符合语法要求。
二. 链接错误（发生在第3步）链接错误，一般是源代码结构不完整，运行时库或函数库使用不合理。
三. 运行时错误（发生在第6步）运行时错误，一般是执行代码时，遇到了事先未料及的错误。
比如内存不足了，磁盘空间不够了，输入文件格式不对了，输出文件写入失败了等等。
四. 计算结果不符合预期（程序代码不规范，或不符合你的设想）计算结果不符合预期，可能性就很多了。
fortran安装调试运行过程中的可能错误及其原因
fortran安装、调试、运行过程中的【可能错误及其原因】-中英对照楼主鲍炜炜2011-04-18 14:37（欢迎加入气象QQ讨论群：149280902，点击即可加入）安装1．关于Fortran编译器的安装和配置？在安装FEPG之前一般要先安装好Powerstation Fortran 4.0编译器，并设置好Fortran编译器的path、lib 和include路径。
如果你的Powerstation Fortran 4.0编译器安装在目录C:\MSDEV下，设置如下：·在WIN 2000/XP下的设置:a.鼠标移到我的电脑图标，单击右键，然后点击属性；b.点击高级属性；c.点击环境变量，进行系统变量设置；系统变量如下图：d. 如果图上的include、lib、path几个变量没有，请点击新建；如有，点击编辑；按下面变量值进行修改：变量：path值：c:\MSDEV\bin; %path%变量：lib 值：c:\MSDEV\lib;%lib%变量：include值：c:\MSDEV\include;%include%注意：如果path、lib和include变量中有相应新增加的内容，可不增加。
如果编译器装在其它目录，则把C:\MSDEV换为该目录名。
实际上，在安装Powerstation Fortran 4.0时，会出现一个对话框，询问是否增加环境变量，如果选是，这些变量就已经配置好了。
安装fepg，需要用户有管理员权限。
2．运行FEPG命令生成Fortran源程序时，出现fl32不是内部命令也不是外部命令的错误(或fl32 is not internal command)？没配置好Fortran编译器的path路径。
按照上面第1个问题中的解答配置好path路径。
3. 运行FEPG命令生成Fortran源程序时，有些fortran源程序没连接成可执行程序，出现不能发现fepg.lib 库文件的错误？安装FEPG之前，没安装和配置好Fortran编译器所致。
fortran90常见错误
1、运行fortran时出现forrt1:severe<59>:list-directed I/O syntax error,unit 1,file G:\1\1\meat.dat怎么办这是通道1 ，链接到文件meat.dat 的读写出错了。
这问题你得认真检查类似read( 1 , * ) 或write( 1 , * ) 这样的语句，错误原因挺多的。
比如二进制文件用了文本方式读取，比如变量列表与文件不匹配。
问：另外forrt1:severe<161>:program exception -array bounds exceeded是怎么回事？回答：数组越界，也是很常见的错误。
比如real a(100)如果你使用了a(101) 就会越界，因为a 数组只有100 个元素。
2、fortran运行提示error M6201：math-**，现将代码贴出，求高手帮忙看看，急求解答！我不能确定你的错误是怎么引起的。
可能咱们的编译器不同。
你的代码在我这里的问题是：虚参和实参精度不同。
在程序中，你定义了部分real*8，但是对应的虚参和返回值却定义为real。
比如主程序里的z1（双精度），传入函数g里面的x却定义为单精度。
主程序Do 死循环了。
z2_jiashe 和 z2_suan 每一次循环都没有发生改变，于是永远跳不出循环。
我给你的建议是：同一个程序，统一使用real*8 或real*4，尽量不要混用，除非你很自信能理清他们的关系。
检查Do 循环，尤其是z2_jiashe 和z2_suan，是否应该每次循环不同？fortran_排除错误(2012-04-20 23:22:44)安装好VISUAL FORTRAN后1、运行Developer studio即可开始编译FORTRAN程序2、选择File菜单中的New选项3、在弹出的对话框选择projects标签，其他标签不用管，projects格式选用Fortran console application；在project name里命名（最好英文名），点击“ok ”4、接下来画面中，选择“an empty project”，点击“finish”5、接下来画面点击“ok”6、再选择一次File菜单中的new7、对话框选用files标签，选择Fortran free format source file ，并在file里命名8、点击“ok”数Source Files 放源文件(.c、.cpp)程序的实现代码全放在这里Header Files 放头文件(.h)声明放在这里Resource Files 资源文件(.rc)放图标、图片、菜单、文字之类的，主要用来做界面的东东一般都放这里External Dependencies 除上三种以外的，程序编译时用到的文件全放这里fortran内部函数出错信息解释内部函数出错信息解释[sourcefile(line)]run-time error M62××MATH错误号函数级数学错误信息M6201 functionnames:DOMAIN error函数的自变量超出了约定的取值域，例如sqrt(-1)M6202 functionname:SING error无意义的变量。

fortran read error 处理
fortran read error 处理Fortran Read Error Handling: A Step-by-Step GuideIn Fortran, read statements are used to input data from a specified source, such as a file or the standard input. However, there are cases where errors can occur during the execution of a read statement, which can lead to program failures or incorrect results. Therefore, it is essential to understand how to effectively handle read errors in Fortran. In this article, we will take a step-by-step approach to guide you through the process of handling Fortran read errors.Step 1: Enable Error HandlingTo begin, you need to enable error handling in your Fortran program. This can be achieved by including the `ERR` parameter in your read statement. The `ERR` parameter allows you to specify an error handling routine that will be executed if an error occurs during the execution of the read statement. For example:READ(UNIT, *, ERR = errorHandler) variableIn this example, `UNIT` is the unit number associated with the input source, `variable` is the variable to store the input data, and`errorHandler` is the name of the error handling routine.Step 2: Define the Error Handling RoutineNext, you need to define the error handling routine that will be executed when an error occurs during the read statement. This routine should handle the error appropriately, such as displaying an error message or taking corrective actions. For example:SUBROUTINE errorHandler()IMPLICIT NONEINTEGER :: errorCodeerrorCode = IOSTAT ! Get the error code from IOSTATSELECT CASE (errorCode)CASE (-1)WRITE(*, *) "End-of-file reached."CASE (-i)WRITE(*, *) "Input error occurred (code = ", ABS(i), ")."CASE (i)WRITE(*, *) "Output error occurred (code = ", i, ")."CASE DEFAULTWRITE(*, *) "Unknown error occurred."END SELECT! Take appropriate actions based on the error...END SUBROUTINE errorHandlerIn this example, we use the `SELECT CASE` construct to handle different error codes. The `IOSTAT` function returns the error code, which can be negative for input errors and positive for output errors. You can customize the error handling routine to suit your specific needs, such as logging errors or terminating the program.Step 3: Implement Error Detection and RecoveryAfter defining the error handling routine, you can now implement error detection and recovery mechanisms in your program. One common approach is to use a loop to continuously read input until a valid data isobtained or an error occurs. For example:INTEGER :: i, errorCodeDOREAD(UNIT, *, ERR = errorHandler, IOSTAT = errorCode) iIF (errorCode == 0) THEN! Valid input obtained, exit the loopEXITELSE! Error occurred, display error message and continue readingCALL errorHandler()END IFEND DOIn this example, the loop continues until a valid input is obtained(`errorCode == 0`), at which point the program exits the loop. If an error occurs, the `errorHandler` routine is called to handle the error and the loop continues.Step 4: Test and DebugFinally, it is crucial to thoroughly test your Fortran program with different input scenarios to ensure the error handling mechanism is functioning correctly. Test for common read errors, such as invalid input types, reaching end-of-file prematurely, or unexpected input format. Use test cases that cover a wide range of possible inputs to verify the effectiveness of your error handling implementation.In conclusion, handling Fortran read errors involves enabling error handling, defining an error handling routine, implementing error detection and recovery mechanisms, and testing and debugging the program. By following this step-by-step guide, you can ensure that your Fortran programs handle read errors effectively, improving the stability and reliability of your code.。

1、运行fortran时出现forrt1:severe<59>:list-directed I/O syntax error,unit 1,file G:\1\1\meat.dat怎么办这是通道1 ，链接到文件meat.dat 的读写出错了。
这问题你得认真检查类似read( 1 , * ) 或write( 1 , * ) 这样的语句，错误原因挺多的。
比如二进制文件用了文本方式读取，比如变量列表与文件不匹配。
问：另外forrt1:severe<161>:program exception -array bounds exceeded是怎么回事？回答：数组越界，也是很常见的错误。
比如real a(100)如果你使用了a(101) 就会越界，因为a 数组只有100 个元素。

常见fortran系统错误
Mistakes in Fortran 90 Programs That Might Surprise YouOver the years we have made lots of interesting and fun mistakes in Fortran 90 that we would like to share with you. We welcome your contributions and experiences so that we can share your pain.TopicsThese "gotchas" are nasty because they will not fail on some machines, while failing on others (given various combinations of compilers and machine platforms).∙Danger with Optional Arguments∙Danger with intent(out)∙ A suprise with non-advancing I/O∙Suprise with locally initialized variables∙Danger of calling Fortran 90 style routines∙Danger with interfaces to Fortran 77 subroutines∙ A suprise with generic functions∙Big Danger with Undefined Pointers∙Subtle danger with overloading (=) to assign pointers∙Danger with pointers to pointersDanger with Optional ArgumentsIn this example an optional argument is used to determine if a header is printed.subroutine print_char(this,header)character(len=*), intent (in) :: thislogical, optional, intent (in) :: header! THIS IS THE WRONG WAYif (present(header) .and. header) thenprint *, 'This is the header 'endifprint *, thissubroutine print_char(this,header)character(len=*), intent (in) :: thislogical, optional, intent (in) :: header! THIS IS THE RIGHT WAYif (present(header)) thenif (header) print *, 'This is the header 'endifprint *, thisend subroutine print_charExplanationThe first method is not safe because the compiler is allowed to evaluate the header argument before the present function is evaluated. If the header argument is not in fact present an out of bounds memory reference could occur, which could cause a failure.Danger with intent(out)In this example we assign components of a derived type with intent(out). program intent_gotchatype mytypeinteger :: xreal :: yend type mytypetype (mytype) :: aa%x = 1 ; a%y = 2.call assign(a)! a%y COULD BE UNDEFINED HEREprint *, acontainssubroutine assign(this)type (mytype), intent (out) :: this! THIS IS THE WRONG WAYthis%x = 2end subroutine assignsubroutine assign(this)type (mytype), intent (out) :: this! THIS IS THE RIGHT WAYthis%x = 2 ; this%y = 2.end subroutine assignExplanationThe problem is that when intent(out) is used with a derived type, any component not assigned in a procedure could become undefined on exit. For example, even though a%y was defined on entry to this routine, it could become undefined on exit because it was never assigned within the routine. The lesson is that all components of a derived type should be assigned within a procedure, when intent(out) is used. Intent(out) behaves like the result variable in a function: all components must be assigned.As an alternative, use intent(inout).A suprise with non-advancing I/OMany people think that the new non-advancing I/O in Fortran 90 is the same as stream I/O in other languages. It is not.do i = 1, 128write (unit=6,fmt='(a)',advance='no') 'X'end doWe expect this program to print 128 X's in a row. However, unexpected behavior may occur if the record length for unit 6 is less than 128.One can inquire the record length in the follow way:open(unit=6)inquire(unit=6, recl=i)print *, 'recl =', iExplanationAll Fortran I/O is still record based. Non-advancing I/O allows partial reads and writes within a record. For many compilers the default record length is very large (e.g., 2147483647) giving the appearance of stream I/O. This is not true for all compilers however.On some compilers it is possible to set the record length as follows:open(unit=6, recl = 2147483646)On other compilers unit 6 is preconnected and the record length cannot be changed. (Thanks to Jon Richards of the USGS for this tip.)Note that unit 6 and unit * are not necessarily the same. Although they both may point to the default output device, with non-advancing I/O, each could keep track of the current location in its own record separately. Therefore we advise choosing one default unit and sticking with it.Suprise with locally initialized variablesOne must be careful when initializing a locally declared variable.real function kinetic_energy(v)real, dimension(:), intent(in) :: vinteger i! THIS IS THE WRONG WAYreal :: ke = 0.0do i = 1, size(v)ke = ke + v(i)**2enddokinetic_energy = .5*keend function kinetic_energyreal function kinetic_energy(v)real, dimension(:), intent(in) :: vinteger i! THIS IS THE RIGHT WAYreal :: keke = 0.do i = 1, size(v)ke = ke + v(i)**2enddokinetic_energy = .5*keend function kinetic_energyExplanationA local variable that is initialized when declared has an implicit save attribute. ke is initialized only the first time the function is called. On subsequent calls the old value of ke is retained. This is a real suprise to C programmers.To avoid confusion it is best to add the save attribute to such locally initialized variables explicitly, even though this is redundant.Danger of calling Fortran 90 style routinesprogram mainreal, dimension(5) :: xx = 0.! THIS IS WRONGcall incb(x)print *, xend program mainsubroutine incb(a)! this is a fortran90 style subroutinereal, dimension(:) :: aa = a + 1.end subroutine incbExplanationThe subroutine incb uses a Fortran 90 style assumed shape array (containing dimension(:)). Such routines must either be in a module, or have an explicit interface wherever they are used. In this example, neither one was true.One correct way to call such procedures is to use an explicit interface as follows:program mainreal, dimension(5) :: x! THIS IS THE RIGHT WAYinterfacesubroutine incb(a)real, dimension(:) :: aend subroutine incbend interfacex = 0.call incb(x)print *, xend program mainsubroutine incb(a)! this is a fortran90 style subroutinereal, dimension(:) :: aa = a + 1.end subroutine incbIf the routine is in a module interfaces are generated automatically and do not need to be explicitly written.! THIS IS ANOTHER RIGHT WAYmodule inccontainssubroutine incb(a)! this is a fortran90 style subroutinereal, dimension(:) :: aa = a + 1.end subroutine incbend module incprogram mainuse increal, dimension(5) :: xx = 0.call incb(x)print *, xend program mainIf interfaces are used, the interface MUST match the actual function. Danger with interfaces to Fortran 77 subroutinesprogram mainreal, dimension(5) :: x! interface to Fortran 77 style routineinterfacesubroutine inca(a,n)integer :: n! THIS IS THE WRONG WAYreal, dimension(:) :: a! THIS IS THE RIGHT WAYreal, dimension(n) :: aend subroutine incaend interfacex = 0.call inca(x,5)print *, xend program mainsubroutine inca(a,n)! this is a fortran77 style subroutinedimension a(n)do 10 j = 1, na(j) = a(j) + 1.10 continuereturnendExplanationThe interface declaration must always match the actual subroutine declaration. In this case, the interface statement refers to a Fortran 90 style assumed shape array. The actual subroutine refers to a Fortran 77 explicit shape array. The lesson here is: Interfaces to Fortran 77 style routines must only use Fortran 77 style constructs.In this example, it is permitted to leave out the interface altogether since routines without interfaces are treated as Fortran77 style routines by default. However, if the interface is left out, the compiler will no longer check whether the arguments of calling procedures agree with the arguments listed in the interface.A Suprise with Generic Functions (Function Overloading)Fortran 90 allows the same function name to be used for different actual functions, so long as the arguments to the functions differ. One would expect that the functions first_sub and second_sub below would be different, because in first_sub, the first argument is a real and the second is an integer, while in second_sub the arguments are reversed. subroutine first_sub(a,i)real :: ainteger :: i...end subroutine first_sub!subroutine second_sub(i,a)integer :: ireal :: a...end subroutine second_subSo that one could define a generic function first_or_second below:interface first_or_secondmodule procedure first, secondend interfaceThis is NOT so.ExplanationThe reason is that Fortran 90 allows procedures to be called by name (keyword) arguments. The followingreal :: binteger :: ncall first_or_second(i=n,a=b)does not work because when called by keyword, first_sub and second_sub are indistinguishable,call first_sub(i=n,a=b)call second_sub(i=n,a=b)and therefore a generic function cannot be defined. A generic function must be able to distinguish its arguments by type AND by name.The solution is to not use the same dummy argument name in both procedures. For example, the following would work:subroutine second_sub(i,aa)integer :: ireal :: aa...end subroutine second_subDangers with PointersFortran 90 has 3 ways to implement dynamic memory: Automatic arrays, allocatable arrays, and pointers.Automatic arrays are automatically created on entry and deleted on exit from a procedure, and they are safest and easiest to use. Allocatable arrays require the user to manually create and delete them, and should only be used if automatic creation and deletion is not the desired behavior.Pointers are the most error prone and should only be used when allocatable arrays are not possible, e.g., when one desires an array to be a component of a derived type.Big Danger with Undefined PointersMany people think that the status of a pointer which has never been associated is .not. associated. This is false.In this example we are allocating a local_table on first entry that is to be reused on subsequent entries.subroutine local_pointer(this)real, dimension(:) :: thisreal, dimension(:), save, pointer :: local_table! THIS IS THE WRONG WAYif (.not. associated(local_table)) thenallocate(local_table(size(this)))endiflocal_table = ......end subroutine local_pointersubroutine local_pointer(this)real, dimension(:) :: thisreal, dimension(:), save, pointer :: local_table! THIS IS THE RIGHT WAYlogical, save :: first_entry = .true.if (first_entry) thennullify(local_table) ; first_entry = .false.end ifif (.not. associated(local_table)) thenallocate(local_table(size(this)))endiflocal_table = ......end subroutine local_pointerExplanationWhen a pointer is declared its status is undefined, and cannot be safely queried with the associated intrinsic. A second variable is introduced to nullify the pointer on first entry so that its status can be safely tested. This is not a problem in Fortran 95 which allows one to nullify a pointer on declaration.Note that the save attribute for local_table is necessary to guarantee that the array and the pointer status are preserved on subsequent entries. We recommend that the save attribute should always be used when pointers and allocatable arrays are allocated in procedures.Subtle danger with overloading (=) to assign pointersOne must be careful with overloading the assignment operator.In this module we have created a private type which contains a pointer and a public procedure to assign that pointer.module assign_pointer_classtype mytypeprivatereal, pointer :: prend type mytypeinterface assignment (=)module procedure assign_pointerend interfacecontainssubroutine assign_pointer(this, a)type (mytype), intent(out) :: thisreal, target, intent(in) :: athis%pr => aend subroutine assign_pointerend module assign_pointer_classIn this main program we intend to assign the pointer component x%pr to the variable a, x%pr =>a. We cannot do so directly because the components of mytype are private. One must use a public procedure to do so. Furthermore, to simplify the syntax one might be tempted to use an overloaded assignment operator (=).program mainuse assign_pointer_classtype (mytype) :: xreal :: a = 0! THIS IS THE WRONG WAYx = aend program mainDon't give into this temptation! The only safe way to accomplish this is to call the procedure directly.program mainuse assign_pointer_classtype (mytype) :: x! THIS IS THE RIGHT WAYreal, target :: a = 0call assign_pointer(x,a)end program mainExplanationThe Fortran 90 standard says that the right hand side of an assignment operator is an expression that may potentially only persist for the duration of the call. In other words, x%pr could inadvertently point to a temporary copy of the variable a.Thanks to Henry Zongaro of IBM for pointing this out. (We never would have figured this one out on our own.)Also, James Giles found a subtle point regarding this example. We did not include "target" in the declaration of the real variable "a" (this has been corrected above). In James' words:"Notice that for this to really work, the actual argument, 'a', must be declared with the target attribute. You correctly declare the dummy argument in the assign_pointer routine with the target attribute, but the actual argument must also have that attribute (otherwise it's illegal for any pointer to be associated with it). Just a minor point..."Danger with pointers to pointersWhen creating a hierarchy of pointers to pointers, each level of pointers must be allocated before being used.program maintype mytypereal, dimension(:), pointer :: pend type mytypetype (mytype), pointer :: x! BOTH OF THESE ARE THE WRONG WAY! AND THE COMPILER WON'T CATCH IT! nullify(x%p)! allocate(x%p(5))! ONE SHOULD ALWAYS IMMEDIATELY NULLIFY THE PARENT POINTER! OR ALLOCATE ITnullify(x) ! or allocate(x)...! THEN LATER NULLIFY OR ALLOCATE THE CHILD POINTERcall child_construct(x,5)if (associated(x%p)) print *, x%pcontainssubroutine child_construct(this,len)! child constructor for pointer within mytype! if len is present, then allocate it, otherwise nullify it.! mytype is assumed to be already nullified or allocatedtype (mytype), pointer :: thisinteger, optional, intent(in) :: lenif (.not.associated(x)) allocate(x)if (present(len)) thenallocate(x%p(len))x%p = 0.elsenullify(x%p)endifend subroutine child_constructend program mainExplanationThis example creates a pointer to a pointer to an array of reals where the first pointer has not been allocated. For safety one should always either allocate or nullify the parent pointer immediately after its declaration. The child pointer cannot be allocated before the parent. Since the child pointer may be allocated elsewhere in the code, it is convenient to use constructor routines for this purpose.Each child constructor can safely allocate or nullify its pointers only when it can be sure that its parent's pointers have been allocated or nullified.。

fortran安装调试运行过程中的可能错误及其原因
fortran安装、调试、运行过程中的【可能错误及其原因】-中英对照楼主鲍炜炜2011-04-18 14:37（欢迎加入气象QQ讨论群：149280902，点击即可加入）安装1．关于Fortran编译器的安装和配置？在安装FEPG之前一般要先安装好Powerstation Fortran 4.0编译器，并设置好Fortran编译器的path、lib 和include路径。
如果你的Powerstation Fortran 4.0编译器安装在目录C:\MSDEV下，设置如下：·在WIN 2000/XP下的设置:a.鼠标移到我的电脑图标，单击右键，然后点击属性；b.点击高级属性；c.点击环境变量，进行系统变量设置；系统变量如下图：d. 如果图上的include、lib、path几个变量没有，请点击新建；如有，点击编辑；按下面变量值进行修改：变量：path值：c:\MSDEV\bin; %path%变量：lib 值：c:\MSDEV\lib;%lib%变量：include值：c:\MSDEV\include;%include%注意：如果path、lib和include变量中有相应新增加的内容，可不增加。
如果编译器装在其它目录，则把C:\MSDEV换为该目录名。
实际上，在安装Powerstation Fortran 4.0时，会出现一个对话框，询问是否增加环境变量，如果选是，这些变量就已经配置好了。
安装fepg，需要用户有管理员权限。
2．运行FEPG命令生成Fortran源程序时，出现fl32不是内部命令也不是外部命令的错误(或fl32 is not internal command)？没配置好Fortran编译器的path路径。
按照上面第1个问题中的解答配置好path路径。
3. 运行FEPG命令生成Fortran源程序时，有些fortran源程序没连接成可执行程序，出现不能发现fepg.lib 库文件的错误？安装FEPG之前，没安装和配置好Fortran编译器所致。

fortran常见问题解决
fortran常见问题解决为了减少重复回答问题，特编此帖，并不定期添加和更新内容。
错误难免，欢迎讨论，仅供参考。
很多人问哪里可以找到Fortran编译器，有不少热心学友提供网址，特汇集在这里。
虽然俺检验过这些链接，但是它们不一定总有效。
Fortran 编译器下载：CVFFTN95 (License: Free for personal use)以下操作，如无特别说明，都是以为例。
1. 如何加大Stack size?选Project => Settings => Link => Category: Output =>Stack allocationsReserve: 这里填新值（默认为1M，若需要10M，则填）2. 如何用Fortran批量生成文件？设要生成4000个文件，文件名为AA1-AA4000，如何写循环生成文件,而不用写4000次write 命令呢?用内部文件：character(len=80) :: filename,forminteger :: ido i=1,4000select case (i)case (1:9)write(form,'(i1)') icase (10:99)write(form,'(i2)') icase (100:999)write(form,'(i3)') icase (1000:9999)write(form,'(i4)') iend selectwrite(filename,*) "AA",trim(form),".TXT"open(10,file=filename)write(10,*) iclose(10)end dostopend3. 如何用Fortran动态生成输出格式？设有一个数组data(100)，输出时，希望每行输出num个数，而num由用户输入，如何实现？用内部文件：character(len=80) :: formreal :: data(100)integer :: i,numdata = (/ (i,i=1,100) /)/read(*,*) numwrite(form,*) "(",num,""write(*,form) datastopend4. MS 是不是很垃圾？是垃圾，其中Bug太多，多到不可用的地步！在这个主题里，换了CVF后问题就没了的人已有相当的数目。
Fortran FAQ
1.1 FAQ之常见错误本文从编译错误，链接错误，运行时错误，计算结果错误等四个方面介绍了常见的错误及解决思路。
适合初学者阅读。
首先应该明确：错误有哪几种？我们当前遇到的是何种错误？阐述这些问题前，我们先讨论一下常规的应用程序开发的过程：1>>编写代码，使用一个或多个源代码文件。
2>>对第一步的每一个源代码文件执行编译操作。
得到一个或若干个目标代码。
3>>将目标代码，运行时库（Run-time Library）和其他使用到的函数库链接起来。
得到一个可执行文件（EXE 或其他）4>>编写程序的说明书，必要的（输入）数据文件5>>将上述得到的结果发布给用户。
（发布的方式可以是刻录成光盘，销售，放在网站上供别人下载，或者其他）6>>用户得到程序后，运行，输入数据，得到计算结果。
对于很多Fortran 程序员来说，可能用户就是自己，也可能仅仅是自己教研室的同事同学。
所以第4，5，6步骤很多时候不明显。
而如果使用集成开发环境（IDE）进行开发，第1，2，3步骤又可以一键完成。
因此，很多初学者就认为，写程序就是：输入代码，运行，得到结果。
这样的理解太狭义。
不管我们面对什么使用者来写代码，程序开发应该是上述的过程。
我们的编译器，编译环境，也是为这个过程而设计的。
于是，我们将错误分为四种：一. 编译错误（发生在第2步）编译错误，一般是源代码书写格式不正确，不符合语法要求。
二. 链接错误（发生在第3步）链接错误，一般是源代码结构不完整，运行时库或函数库使用不合理。
三. 运行时错误（发生在第6步）运行时错误，一般是执行代码时，遇到了事先未料及的错误。
比如内存不足了，磁盘空间不够了，输入文件格式不对了，输出文件写入失败了等等。
四. 计算结果不符合预期（程序代码不规范，或不符合你的设想）计算结果不符合预期，可能性就很多了。
语法与你的想法不一致，超出函数库的适用范围，执行流程控制不当等等。
gfortran编译
gfortran编译gfortran编译器是GNU编译器套件（GCC）中的一部分，专门用于编译Fortran语言程序。
本文将介绍gfortran编译器的基本使用方法、编译选项和一些常见问题的解决方案。
一、gfortran编译器简介gfortran是一个开源的Fortran编译器，由GNU开发并维护。
它支持Fortran 95、Fortran 2003和Fortran 2008标准，并提供了许多扩展功能。
gfortran编译器可在多个平台上运行，包括Linux、macOS和Windows等。
1. Linux系统：可以使用包管理器安装gfortran，如在Ubuntu上使用apt命令：sudo apt-get install gfortran。
2. macOS系统：可以使用Homebrew包管理器安装gfortran，如：brew install gfortran。
3. Windows系统：可以从MinGW-w64项目的官方网站下载并安装gfortran。
三、使用gfortran编译器1. 编写Fortran源代码：使用任何文本编辑器创建一个以".f"或".f90"为后缀的Fortran源代码文件，例如hello.f90。
2. 编译源代码：打开终端或命令提示符窗口，使用gfortran命令编译源代码。
例如：gfortran -o hello hello.f90。
3. 运行可执行文件：编译成功后，可以运行生成的可执行文件。
例如：./hello（Linux/macOS）或hello.exe（Windows）。
四、编译选项gfortran编译器提供了许多编译选项，可以根据需要进行配置。
以下是一些常用的选项：1. -o <output>：指定生成的可执行文件的名称。
2. -c：只编译源代码，生成目标文件而不链接。
3. -Wall：显示所有警告信息。
4. -O<level>：指定优化级别，如-O0（禁用优化）、-O1（基本优化）等。
intel fortran新手入门常遇到的问题
安装简单地说一下，安装intelfortran之前，需提前安装visual studio 2008 2010 2012版本中的一个。
Intel fortran启动，程序中点击visual studio图标
然后是点击菜单栏上的文件—新建—项目，新建一个项目。
新建项目后，会在左侧栏里出现如下内容
如果没有出现上面的内容，请在下方，点击选项卡“解决方案资源管理器”
选中source files
接下来，有的同学会直接点文件，新建文件。
这样的选择不对，会出现“无法启动程序......系统无法找到指定的路径”这样的提示
正确的做法应该是点击项目—添加新项，然后添加free或者format格式
左侧栏会出现一个脚本文件
现在一切OK
开始写第一个程序
你会发现dos黑窗口一闪没了，怎么办？
不要紧你只要在程序后面加read(*,*)就可以了

. Fortran 运行中给出的系统错误及解决方法以下均为linker tools errors and warningsLinker Tools Error LNK1000unknown error; consult documentation for technical support options Note the circumstances of the error, try to isolate the problem and create a reproducible test case, then contact technical support.Linker Tools Error LNK1101incorrect MSPDBxx.DLL version; recheck installation of this product The version of MSPDBxx.DLL available on your system does not match the version required by this tool.Linker Tools Error LNK1102out of memoryThere was not enough memory for the tool to run. Probably the paging file exceeded available disk space. If a shortage of disk space is not the cause, note the circumstances of the error, try to isolate the problem and create a reproducible test case, then request technical support.Linker Tools Error LNK1103debugging information corrupt; recompile moduleProbably the compilation was terminated before a valid object file was created.Recompile the given object file. If recompiling does not correct the problem,note the circumstances of the error, try to isolate the problem and create a reproducible test case, then consult technical support.Linker Tools Error LNK1104cannot open file "filename"The tool could not open the given file. One of the following may be a cause:l There was not enough disk space.l The file does not exist.l The filename or its path was incorrectly specified.l The specified drive is invalid.l The file does not have the appropriate permissions.l The path for filename expands to more than 260 characters.l If the given file is named LNKn, which is a filename generated by the linker for a temporary file, then the directory specified in the TMP environment variable may not exist, or more than one directory is specified for the TMP environment variable. (Only one directory path should be specified for the TMP environment variable.) l If the error occurs on the executable filename, an earlier version of the executable may still be running. You will need to terminate the executable before linking it. In Windows NT (including Windows 2000) or Windows 95,you can use the utility PVIEWto look for and kill instances of the application.l If the error message occurs for a library name, and you recently ported the .MAK file from a previous Microsoft Visual C++ developmentLinker Tools Messages Page 3 of 37environment, the library may no longer be valid. Ensure that the library still exists in this circumstance.l If the error message occurs for a library name such as CONSOLE.LIB, and you included object modules from an older Fortran developmentenvironment such as Microsoft Fortran PowerStation, recompile all source files with Visual Fortran to create new object files and libraries.Linker Tools Error LNK1105cannot close file "filename"The tool could not close the given file. Possibly there was insufficient disk space available.Linker Tools Error LNK1106invalid file or disk full: cannot seek to locationThe tool could not read or write to location in a memory-mapped file:l Your disk may be too full to complete the link. Free up some space and try the link again.l The error may be a result of trying to link over a network. Some networks do not fully support the memory-mapped files used by the linker. Try linking on your local disk to see if that fixes the problem.l There may be a bad block on your disk. Although the operating system and disk hardware should have detected such an error, you may want to run a disk checking program.Linker Tools Error LNK1107invalid or corrupt file: cannot read at locationThe tool could not read the file. Recreate the file.Linker Tools Error LNK1108cannot write file at locationThe tool could not write to the file. One of the following may be a cause:l There was not enough disk space to create the file.l The drive being written to was not available, possibly due to a network problem.Linker Tools Error LNK1109cannot remove file "filename"LIB could not delete the given file. Before LIB writes the new version of a library, it removes the existing library file. One of the following may be a cause:l The given file does not have the appropriate permissions.l The drive containing the file was not available, possibly due to a network problem.Linker Tools Error LNK1110Linker Tools Messages Page 4 of 37cannot rename file "filename"LIB could not rename the given file. When LIB builds a new version of a library, it creates a temporary file, then renames the file. One of the following may be a cause:l The given file does not have the appropriate permissions.l The drive containing the file was not available, possibly due to a network problem.Linker Tools Error LNK1111invalid /BASE argument "argument"The /BASE option was incorrectly specified. Either no argument was specified or argument is not a number.Linker Tools Error LNK1112module machine type "type1" conflicts with target machine type "type2"The object files specified as input were compiled for different machine types.Linker Tools Error LNK1113invalid machine typeThe machine type specified in the object header is not valid. Probably the file is corrupt. Rebuild the object. See Corrupt Object File for more information.Linker Tools Error LNK1115/MACHINE option requiredLINK or LIB cannot determine the machine type for objects that are provided entirely from libraries. Either specify the /MACHINE option with the appropriate machine type or specify at least one object file in the input.Linker Tools Error LNK1117syntax error in option "option"The given option was not correctly specified.Linker Tools Error LNK1118syntax error in keyword statementThe given module-definition statement was not correctly specified.Linker Tools Error LNK1119invalid ordinal number "argument"The argument following the at sign (@) in an ordinal specification was not a valid number. An ordinal number is an optional argument in either an /EXPORT option in a LINK or LIB command or an EXPORTS statement in a moduledefinitionfile. It is an index into the exports table. The number must be aninteger in the range 1-65535.Linker Tools Error LNK1120number unresolved externalsLinker Tools Messages Page 5 of 37Error LNK1120 gives you a count (number) of unresolved externals for this link. The conditions that cause unresolved externals are described with errorLNK2001 (see Linker Errors LNK2001 to LNK2014), which precedes this error message (once for each unresolved external).Linker Tools Error LNK1121duplicate ordinal number "number"The given ordinal number was specified more than once in either an /EXPORT option in a LINK or LIB command or an EXPORTS statement in a moduledefinition file. Ordinal numbers must be unique integers in the range 1-65535.Linker Tools Error LNK1123failure during conversion to COFF: file invalid or corruptThe object or resource could not be converted to COFF. This tool requires the format of all input files to be COFF. If an input file is not COFF, the tool runs aconversion tool, either CVTOMF (to convert 32-bit OMF objects) or CVTRES (to convert resource files). This error is preceded by errors or warnings from the conversion tool. One of the following may be a cause:l The file is corrupt.l The file is not a valid file type. An example of an invalid type is a 16-bit OMF object.Linker Tools Error LNK1127library is corruptThe library file is corrupt. Rebuild the library.Linker Tools Error LNK1129cannot find resolution for weak extern symbolThe given weak external symbol does not have a default resolution. Probablythe symbol table is corrupt. Rebuild the object file. See Corrupt Object File for more information.Linker Tools Error LNK1130Linker miscalc (base relocations off by number)There was not enough space in the image to write base relocations.Linker Tools Error LNK1131no library file specifiedThe LIB /EXTRACT command required a library as input, but a library filename was not specified.Linker Tools Error LNK1132invalid format for MS-DOS stub file "filename"The filename specified with the /STUB option was not a valid real-mode MS-DOS executable (.EXE) file.Linker Tools Messages Page 6 of 37Linker Tools Error LNK1136invalid or corrupt fileThe input file either has a corrupt header or is zero size or abnormally small. See Corrupt Object File for more information.Linker Tools Error LNK1137invalid argument specified with /SECTIONEither the name or the attributes argument to the /SECTION option is specified incorrectly.Linker Tools Error LNK1140too many modules for program database; relink with /PDB:NONEThe project contains more than 4096 modules. One of the following is asolution:l Relink using /PDB:NONE.l Compile some modules without debugging information.l Reduce the number of modules.Linker Tools Error LNK1141failure during build of exports fileLINK could not build the exports (.EXP) file. Causes of this error include system problems such as insufficient memory and syntax errors in options or moduledefinitionstatements. This error is preceded by another error that givesadditional information.Linker Tools Error LNK1143invalid or corrupt file: no symbol for COMDAT section numberThe object file is corrupt. Rebuild the file. See Corrupt Object File for more information.Linker Tools Error LNK1144error with LINK_REPRO var; cannot open "filename"The linker could not create filename. One of the following may be a cause:l Check that you've set your LINK_REPRO environment variable to anexisting directory and not the current directory.l Make sure there are no read-only files in the directory.l Make sure none of the files in the LINK_REPRO directory are open byanother process, because the linker needs to write to them.Linker Tools Error LNK1145/MERGE created circular link for section "section"You attempted to merge a section into itself. Check the /MERGE options.Linker Tools Error LNK1146Linker Tools Messages Page 7 of 37no argument specified with option "option"The given option requires an argument.Linker Tools Error LNK1147invalid number specified with option "option"The argument to the given option was specified incorrectly.Linker Tools Error LNK1148failure during conversion to COFF: cannot copy temp file filenameEDITBIN could not convert the input file to COFF. When EDITBIN converts a file, it creates a temporary file, then copies the file. One of the following may be a cause:l The given file does not have the appropriate permissions.l There was not enough disk space to create the file.l The drive being written to was not available, possibly due to a network problem.Linker Tools Error LNK1149output filename matches input filename "filename"The output filename specified with the /OUT or /IMPLIB option was the same asan input file.Return to Main Linker Error PageLinker Errors LNK1152 to LNK1189Linker Tools Error LNK1152cannot resolve one or more undecorated symbolsThis error is preceded by one warning LNK4022 for each undecorated symbolthat could not be resolved and by at least two warnings LNK4006 for theduplicate symbols found for the undecorated symbol.Linker Tools Error LNK1153/VXD command-line option requiredYou attempted to build a virtual device driver without the /VXD option. Relink with the /VXD option.Linker Tools Error LNK1154specified import library filename matches exports file "filename"The filename specified with LINK /IMPORT or with LIB /DEF /OUT conflicted with the filename given by LINK or LIB to the exports file, which is formed from the base name of the main output file and the extension .EXP.Linker Tools Error LNK1155special symbol "symbol" already definedLinker Tools Messages Page 8 of 37The given symbol is reserved for use by LINK.Linker Tools Error LNK1156.sbss section not supportedAn object file contained an .sbss section.Linker Tools Error LNK1157fixup overflow; offset of target symbol "symbol" greater than +-8MBThe VXD is too large, or the sections are not arranged properly.Linker Tools Error LNK1158cannot run "filename"The given executable file called by LINK is not in the directory that contains LINK and is not in a directory specified in the PATH environment variable. Linker Tools Error LNK1159no output file specifiedNo name was specified for the main output file (executable file or DLL). LINK derives the default name of the output file from the base name of the first object file. If no object files are specified, and if the /OUT option is not used, this error occurs.Linker Tools Error LNK1160library with zero objects not allowedAn attempt was made to remove an object from a library that contained onlythat object. The object was not removed.Linker Tools Error LNK1161invalid export specificationEither the /EXPORT option or the EXPORTS module-definition statementincorrectly specified an export. A possible cause is a typing error.Linker Tools Error LNK1162expected aux symbol for comdat section numberThe linker expected to find an auxiliary symbol table for the indicated COMDAT but could not. The object file is probably corrupt. See Corrupt Object File for more information.Linker Tools Error LNK1163invalid selection for comdat section numberThe byte in the object file indicating the type of COMDAT section is invalid. The object file is probably corrupt. See Corrupt Object File for more information. Linker Tools Error LNK1164section section alignment (number) greater than /ALIGN valueThe alignment size for the given section in the object file exceeds the value specified with the /ALIGN option. The /ALIGN value must be a power of 2 and Linker Tools Messages Page 9 of 37must equal or exceed the section alignment given in the object file. Either recompile with a smaller section alignment or increase the /ALIGN value.Linker Tools Error LNK1165link failed because of fixup errorsThe build failed due to fixup errors. The /FORCE or /FORCE:UNRESOLVED option overrides this error.Linker Tools Error LNK1166cannot adjust code at offset=offset, va=valueLINK was unable to pad the code as required. Certain instructions are not allowed to cross page boundaries on some processors. LINK attempts to addpads to correct this situation. In this case, LINK could not work around the problem.Linker Tools Error LNK1167file contains relocs but header has no machine typeA converted COFF object did not have a machine type specified in its header. One cause of this error is omitting a machine type when converting a .RES file in a separate step before linking.Linker Tools Error LNK1168cannot open filename for writingThe given file does not have write permission.Linker Tools Error LNK1169one or more multiply defined symbols foundThe build failed due to multiple definitions of one or more symbols. This error is preceded by error LNK2005. The /FORCE or /FORCE:MULTIPLE option overridesthis error.Linker Tools Error LNK1170line in command file contains limit or more charactersThe length of a line in a command file must be less than the given limit. Linker Tools Error LNK1171unable to load filenameThe given DLL was unavailable. The possible locations for the DLL are the current directory, the system directory, the Windows directory, and the directories specified in the PATH environment variable.Linker Tools Error LNK1172more than one object with the name "object" found; rename object(s) orrelink /PDB:NONEA library contained two or more objects with the same name. Do one of the following:Linker Tools Messages Page 10 of 37l Rename the objects using unique names and rebuild the library.l Link using the /PDB:NONE option.Linker Tools Error LNK1173unable to find entrypoint function in filenameThe given function does not exist in the given DLL.Linker Tools Error LNK1174unable to /REBASE filename; not a valid Win32 imageThe format of the given file was invalid.Linker Tools Error LNK1175failed to /REBASE filenameThe rebase operation failed on the given file.Linker Tools Error LNK1177TOC size limit exceededThe linker was unable to create a TOC (Table of Contents) in your image file. The limit is 2048 entries in the TOC.Linker Tools Error LNK1178missing MODEND record; file is invalid or corruptThe linker tool tried to convert an OMF object module to COFF format but could not find an expected MODEND (module end) record in the OMF object. The OMF object module is corrupt and needs to be recreated or recopied. See Corrupt Object File for more information.Linker Tools Error LNK1179invalid or corrupt file: duplicate comdat comdatAn object module contained two or more COMDATs with the same name. Onepossible cause is if you use the Visual C++ /H option with the Visual C++ /Gy option. The /H option limits the length of external names, and the /Gy option packages functions in COMDATs.Linker Tools Error LNK1180insufficient disk space to complete linkThe linker tool was unable to complete a file operation since the operating system reported that the disk is full. Free up space on your local and network drives (if you are writing files there).Linker Tools Error LNK1181cannot open input file "filename"The linker tool could not find "filename" because it does not exist or the path was not found.Linker Tools Error LNK1182Linker Tools Messages Page 11 of 37cannot have more than 64K exportsYou have reached the linker's limit of 65,536 exports.Linker Tools Error LNK1183invalid or corrupt file: extended relocation count number less than 65535The COFF object file is corrupt since it contains an extended relocation count that is less than 0xFFFF. See Corrupt Object File for more information.Linker Tools Error LNK1184invalid section name "section" specified in option or directive "option"You gave the linker an invalid section name in option. Invalid section names contain "$" or blanks.Linker Tools Error LNK1185invalid section name "section" specifiedYou gave the linker an invalid section name in a .DEF file. Invalid section names contain "$" or blanks.Linker Tools Error LNK1186invalid or corrupt COFF object; reloc to undefined static symbol "symbol"Your COFF object module is corrupt since it contains a relocation entry for an undefined static symbol. See Corrupt Object File for more information.Linker Tools Error LNK1187Corrupt object - unmatched name relocation; ignoredYour object file contains bad relocation information. Recopy or recreate the object file. See Corrupt Object File for more information.Linker Tools Error LNK1188BADFIXUPSECTION:: invalid fixup target "symbol"; possible zero length section This message is issued only for VxD links when the target of a relocation does not have a section. With LINK386 (an older version), an OMF GROUP record (generated by a MASM GROUP directive) may have been used to combine thezero length section with another non-zero length section. COFF format does not support the GROUP directive and zero-length sections. When LINK automatically converts this type of OMF objects to COFF, this error may occur.Linker Tools Error LNK1189LIBTOOMANYMEMBERS:: library limit of number objects exceededThe limit of 65535 objects or members in a library has been exceeded.Return to Main Linker Error PageLinker Errors LNK1190 to LNK1581Linker Tools Error LNK1190Linker Tools Messages Page 12 of 37invalid fixup found, type typeThe object file has become corrupted.
