Xcas requires libGL?

[Simon Pickering]

I imagine that this is normally hidden by the fact that fltk is compiled with OpenGL support, but fltk can be compiled without this (as I did for my Nokia N800). I'm assuming this is an issue caused by the lack of libGL.so, rather than a faulty fltk install (as the header file chain starts there).

In any case, I'm getting the following errors:

Can giac/xcas be made to compile without requiring OpenGL support? Or is this a problem with my fltk install/header files?

Thanks,

Hello!

Your error seems a fltk error, but I'm afraid I didn't take care to add GL checks inside xcas code. I assumed that FLTK implied GL, I'll try to add the checks sometimes in the future.
