Hi André, I think I'm trying to build an X11 application - I'm trying to use a library called VTK (http://www.vtk.org/). I don't believe it uses glut, and I do see a bunch of X11 options in the CMake files. Even if there is no support for hardware acceleration with this method, it should still build, right? I do have C:\Windows\System32\opengl32.dll . I should also have the w32api package because I installed all of the cygwin packages. Any other thoughts of things that would causes these linking errors?
