Nios wont compile C program

[Altera_Forum]

I have just installed the Quartus and Nios2 on my computer, i tried running the my C program in Nios2 IDE that previously compiled and worked well at my uni lab. However this error appears now: 

 **** Incremental build of configuration Debug for project hello_world_small_0 ****  make -s all  Creating generated_app.mk... Compiling alt_exception_muldiv.S... Compiling alt_exception_trap.S...  6 [main] nios2-elf-gcc 5580 fork_copy: linked dll data/bss pass 0 failed, 0x576000..0x576264, done 0, windows pid 5044, Win32 error 487 1017687 [main] nios2-elf-gcc 5580 fork_copy: linked dll data/bss pass 0 failed, 0x576000..0x576264, done 0, windows pid 2324, Win32 error 487 3038565 [main] nios2-elf-gcc 5580 fork_copy: linked dll data/bss pass 0 failed, 0x576000..0x576264, done 0, windows pid 6176, Win32 error 487 7067131 [main] nios2-elf-gcc 5580 fork_copy: linked dll data/bss pass 0 failed, 0x576000..0x576264, done 0, windows pid 6252, Win32 error 487 nios2-elf-gcc: fork: Resource temporarily unavailable make[1]: *** [obj/alt_exception_trap.o] Error 1 make: *** [system_project] Error 2 Build completed  can anyone tell me what is wrong and what can i do? my guess is the C library has errors or not identifiable by nios.  thankyou.

Look at this (http://forum.niosforum.com/forum/index.php?showtopic=3651&hl=fork_copy) thread. 

 Your issue is some sort of conflict between cygwin (which the Altera embedded tools depend upon) and one of your other processes.  Cheers,  - slacker
