NIOS II9.0与WIN7兼容性问题

关键之处是把相应的编译软件改为与XP SP3或SP2的兼容模式，以管理员的模式运行即可

I am sharing my personal experience here. I have been using Quartus I I 9.1 and NIOS II IDE 9.1 on Windows 7 since they were released. Now, I am using Quartus II 9.1 SP2 and NIOS II IDE 9.1 SP2.

A lot of users were asking questions the compatibility of these softw ares on Windows 7.

Quartus II 9.1 and its SOPC builder seem to work fine on Windows 7 si nce the first day they are installed.

It is the NIOS II IDE 9.1 that really bothered me. Most of the time w hen you build a project, it will report error messages like two examp les below. The success rate is only 20%.

Example 1:

make -s all includes

3 [main] ? (3732) c:\altera\91\quartus\bin\cygwin\bin\make.exe: ***fa tal error - couldn't allocate heap, Win32 error487, base 0x9E0000, to p 0xB30000, reserve_size 1372160, allocsize 1376256, page_const 4096 2 [main] make 7588 fork: child -1 - died waiting for longjmp before i nitialization, retry 0, exit code 0x100, errno 11

make: vfork: Resource temporarily unavailable

Example 2:

make -s all includes

3 [main] ? (4980) c:\altera\91\quartus\bin\cygwin\bin\make.exe: ***fa tal error - couldn't allocate heap, Win32 error 487, base 0x970000, t op 0xA40000, reserve_size 847872, allocsize 851968, page_const 4096 2 [main] make 1972 fork: child -1 - died waiting for longjmp before i nitialization, retry 0, exit code 0x100, errno 11

Some says it is related to the Norton Antivirus software. Yes, my PC is installed with Norton Antivirus software. But I observed that it h appened to Windows 7 PC which is not installed with Norton Antivirus software, as well. Turning off the Norton Antivirus software does sli ghtly help to increase the probability that the project is successful ly built, from 20% to about 40%.

Anyway, I found some tricks which can make your life easier if you ar e using Nios II IDE 9.1 on Windows7.

Under your Quartus II folder, go to bin->cygwin->bin folder, select t he following files in the list below and then right-click and choose Properties. Under the Compatibility tab, check“Run this program in c ompatibility mode for:” and choose “Windows XP (Service Pack 2)”. Check “Run this program as an administrator”, as well.
