Unable to run on RHEL 7

[barskey]

Has anyone had any success in running this on RHEL 7? Running the compiled program results in "unable to load driver: swrast_dri.so". I have installed:
mesa-libGL
mesa-libGLU
libX11 4.el7_9

Attempting to compile results in:
../gdsoglviewer/gdsobject_ogl.cpp:425:14 error: call of overloaded 'abs(float&)' is ambiguous
if (abs(fps) > _Quality*5 {

Any tips or help would be appreciated. Thank you!
