The program works fine when I compile and link without -mno-cygwin and the graphs are rendered fine. However, if I add -mno-cygwin to the compile line and "-L/usr/lib/mingw -lstdc++" to the link line, all I get is a black screen. I am using GLUT to create the window and the menus and all of those work fine but there is nothing rendered into the window. I do not get any errors either. I do not get any compiler/linker warnings or errors when I compile with -mno-cygwin. Are there any dependencies that OpenGL has with cygwin1.dll? The link line uses the libraries in the order "-lglut32 -lglu32 -lopengl32" which seems to be what the documentation says. Here are the cygcheck outputs with and without mno-cygwin: * With mno-cygwin: mathgraph.exe: C:\WINDOWS\system32\msvcrt.dll C:\WINDOWS\system32\KERNEL32.dll C:\WINDOWS\system32\ntdll.dll C:\WINDOWS\system32\GLU32.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 C:\WINDOWS\system32\glut32.dll C:\WINDOWS\system32\WINMM.dll * Without mno-cygwin mathgraph.exe: C:\Program Files\Cygwin\bin\cygwin1.dll C:\WINDOWS\system32\ADVAPI32.DLL C:\WINDOWS\system32\ntdll.dll C:\WINDOWS\system32\KERNEL32.dll C:\WINDOWS\system32\RPCRT4.dll C:\WINDOWS\system32\GLU32.DLL C:\WINDOWS\system32\msvcrt.dll C:\WINDOWS\system32\OPENGL32.dll C:\WINDOWS\system32\GDI32.dll C:\WINDOWS\system32\USER32.dll C:\WINDOWS\system32\DDRAW.dll C:\WINDOWS\system32\DCIMAN32.dll C:\WINDOWS\system32\glut32.dll C:\WINDOWS\system32\WINMM.dll I would appreciate any help with this.
