Issue description

When using (require sgl sgl/gl-vectors)
Racket throws the error:
ffi-lib: couldn't open "libGLU.so.1" (libGLU.so.1: cannot open shared object file: No such file or directory). Sadly, installing libGLU(thus, libGLU.so.1) doesn't fix the error.

Steps to reproduce

nix-env -iA nixos.racket
store #lang racket (require sgl sgl/gl-vectors) (gl-begin 'triangles) (gl-vertex 1 2 3) (gl-vertex-v (gl-float-vector 1 2 3 4)) (gl-end) into a file
racket filename.rkt

  • system: "x86_64-linux"
  • host os: Linux 4.19.12, NixOS, 18.09.1806.928ff62213b (Jellyfish)

Does adding libGLU's .../lib to the LD_LIBRARY_PATH environment variable help?

The answer is yes. I will add libGL and libGLU to racket's lib dependencies.
