原创 WIN7下，NIOSII IDE中关于cygwin编译报错的处理

A lot of users were asking questions the compatibility of these
softwares on Windows 7.
Quartus II 9.1 and its SOPC builder seem to work fine
on Windows 7 since the first day they are installed.

It is the NIOS II IDE 9.1 that really bothered me. Most of the time when
you build a project, it will report
error messages like two examples 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: ***fatal error - couldn't
allocate heap,
Win32 error487, base
0x9E0000, top 0xB30000, reserve_size 1372160, allocsize 1376256, page_const
4096
2 [main] make 7588 fork: child -1 - died waiting for longjmp before
initialization, 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: ***fatal error - couldn't
allocate heap,
Win32 error 487, base 0x970000, top 0xA40000,

2 [main] make 1972
fork: child -1 - died waiting for longjmp before initialization, 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 happened to Windows 7 PC which is not installed with Norton Antivirus
software, as well. Turning off the Norton Antivirus software does slightly help
to increase the probability that the project is successfully built, from 20% to
about 40%.

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

Under your Quartus II folder, go to bin->cygwin->bin folder,
select the following files in the list below and then right-click and choose
Properties. Under the Compatibility tab,
check “Run this program in
compatibility mode for:” and choose “Windows XP (Service Pack 2)”. Check “Run this program as an
administrator”, as well.
Here is the list of files that you can select
to change their compatibility mode under the Quartus
II->bin->cygwin->bin folder:
1. Make.exe
2. Sh.exe
3. Echo.exe
4.
Cygstart.exe
5. MakeInfo.exe
6.
Perl.exe
7. Collect2.exe (under nios2eds\bin\nios2-gnutools\
H-i686-pc-cygwin\libexec\gcc\nios2-elf\3.4.6)
8.
Nios2-elf-g++.exe (under
nios2eds\bin\nios2-gnutools\ H-i686-pc-cygwin\bin)
