NIOS 与window7的兼容问题

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)

By doing the steps mentioned above, the success rate of building a project in NIOS II IDE 9.1 will be increased to above 90%.
