最近用Win7开发NIOS，发现了一些编译问题，出现了如下提示
make -s all includes 3 [main] ? (3732) c:\altera\90\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
去网上搜了一下，有解决方法，如下
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)
