Hi all!
I'm currently trying for the first time to compile a window executable file. I tried using cygwin, since I am a bit familiar with it. I installed all that could be required and compiled gambit without any problems. Then I try to compile and link my program which also uses opengl, glu and glut. Everything compiles just fine, but problems arise when I get to the linking stage... Here I get undefined references from both glu and gambit internals. The output I have is:

I can confirm that the librairies libopengl32 libglu32 libglut32 are in /lib/w32api and that libgamc is in /home/admin/gambit-c/current/lib. Can anyone guess where my problem lies?
Many thanks for your help! ^_^
