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。

Fortran运行中给出的系统错误及解决方法

. 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 PVIEW to 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 atemporary 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 avalid number. An ordinal number is an optional argument in either an /EXPORToption 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 a conversion 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 filenamewas 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 moduledefinition statements. 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. Relinkwith 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 thebase 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 only that object. The object was not removed.Linker Tools Error LNK1161invalid export specificationEither the /EXPORT option or the EXPORTS module-definition statement incorrectly 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 add pads 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 overrides this 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. One possible 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.

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。

fortran unclassifiable statement at (1)

fortran unclassifiable statement at (1)
在Fortran编程语言中，错误消息"fortran unclassifiable statement at (1)" 通常表示编译器遇到了它无法识别的语句。

这可能是由于多种原因造成的，以下是一些常见的原因：
1.语法错误：代码中可能存在拼写错误、错误的符号使用，或者缺少某些必需的关键字。

2.代码结构问题：在某些情况下，可能是由于程序的结构问题，例如，子程序或函数调用
中的错误。

3.不支持的特性：如果尝试使用Fortran标准中不支持的特性或功能，也可能会触发此错
误。

4.混合编程：在某些情况下，如果Fortran代码与其他编程语言（如C或C++）混合编写，
可能会因为不兼容的语法或结构而出现此错误。

5.版本不匹配：编译器的版本可能不兼容你的代码。

尝试更新或更改编译器可能会解决这
个问题。

6.使用了过时或不推荐使用的语法或函数：尽管这些功能在旧版本的Fortran中是有效的，
但现代版本的Fortran可能不再支持这些功能。

为了解决这个问题，你可以：
•检查代码中的语法错误，确保所有的语句都是正确的。

•确保所有的子程序和函数调用都是正确的。

•查阅Fortran文档，确保你正在使用的所有特性都是当前标准所支持的。

•如果与其他语言混合编程，请确保你遵循了正确的混合编程规范。

•更新或更改编译器，确保它与你的代码兼容。

•考虑使用现代的Fortran编程实践和标准。

调试程序时，宜用debug模式；调好后再用release模式，得到高效的执行程序。

设定debug模式：点击菜单Build/Set Active Project Configuration,选*- Win32 Debug, OK,即设定为debug 模式。

以debug 模式执行：点击"Go （F5）”按钮，或直接按F5键，则执行程序，并在第一个出错语句处停止，在该语句前有一个小黄色箭头。

若程序没错, 则一直执行完毕，自动关闭dos窗口。

此时，宜用“！〃按钮或"Ctrl+F5〃键，执行完成后，dos窗口等待用户关闭。

设置断点：若希望执行时在某一语句处暂停，可将光标置于该语句，点击〃手〃形状的按钮，或按F9键，则程序执行到该语句时停在该语句处。

单步执行：F10 （不进入了过程程序段）或者FM （遇到了过程进入了过程程序段继续单步执行）。

在工具栏上都有相应的按钮。

查看变量值：小黄箭头停在某语句时，按下Variable按钮，显示当前程序段的变量值；对于简单变量，将光标放在该变量上，则即时显示该变量值。

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编译器常见错误提示及原因

附录：常见错误提示及原因安装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。

在安装FEPG之后出现此情况，可先按照上面第1个问题中的解答配置好Fortran编译器，然后在dos窗口下，运行FEPG所在目录下nfe.r8目录下的gfepglib.bat程序，即可生成fepg.lib库文件。
