[Haskell-cafe] GHC and GLUT

I wonder if anybody has experience with the GLUT library that GHC currently supports? I was trying to use freeglut because I need the actionOnWindowClose function. GHC documentation seems to indicate it's possible to do this, but my effort isn't successful. I even replaced the system-wide libglut.so with the new libglut.so that comes with freeglut installation, but GHC still won't recognize it's now freeglut and I still can't use the actionOnWindowClose function. This is on Linux, and I've not tried Windows. Do I need to compile GHC myself in order to enable freeglut support? Any help is greatly appreciately! Regards, Paul L
