So I compiled without -mno-cygwin. According to cygcheck, I get the correct dlls (dump enclosed below). This time the program runs silently, and exits without popping up a window and with no errors. From appropriately placed print statements, it appears that the program is having trouble creating a window with glutCreateWindow and appears to die silently before completing that step (or just after). As I mentioned earlier, I will try to create a pared-down version that recreates the problem: might be easier to circulate the src then, if anyone wants to try their hand at compiling it... euclid 8:00pm [3d_diameter]> cygcheck main.exe Found: .\main.exe main.exe C:\cygwin\bin\cygwin1.dll C:\WINDOWS\System32\KERNEL32.dll C:\WINDOWS\System32\ntdll.dll C:\WINDOWS\System32\GLU32.DLL C:\WINDOWS\System32\msvcrt.dll C:\WINDOWS\System32\OPENGL32.dll C:\WINDOWS\System32\ADVAPI32.dll C:\WINDOWS\System32\RPCRT4.dll C:\WINDOWS\System32\GDI32.dll C:\WINDOWS\System32\USER32.dll C:\WINDOWS\System32\DDRAW.dll C:\WINDOWS\System32\DCIMAN32.dll .\glut32.dll C:\WINDOWS\System32\WINMM.dll Suresh Venkatasubramanian, Ph: 973 360 8951 (o) Member, Technical Staff Web: http://www.research.att.com/~suresh/ AT&T Shannon Labs "The guitar is the ideal instrument for anyone who is able to love loneliness." --Angelo Gilardino -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
