Compiling GLEW with Cygwin, undefined references (mostly to glXGetProcAddressARB)

I am trying to compile GLEW in cygwin. I downloaded glew version 1.11.0 from the website and extracted it into C:\glew-1.11.0\. Then after navigating into the folder in cygwin (run as admin) and doing make, it errors with the following. Doing make all does the same (if this matters).

/cygdrive/c/glew-1.11.0

Any idea how to get glew to compile?

Solution

  • GLEW packages are available in Cygwin Ports; you can see how they are built here.
