Hello, I played this years ago on Linux, thought I'd get it running again on a 2014 MacBook Pro (which runs BZFlag very well)! I've got Xcode 9.4.1, MacOSX 10.13.6 (High Sierra), macports, command line tools for 9.4.1, the Nvidia 387.10.10.10.40.108 Graphics drivers, SFML 2.4.2 (comes from macports but was missing pkgconfig files - now fixed), libGLU (also macports), and the quadtree.cpp patched so line 785, != 0. Also, all text.setColor converted to text.setFillColor (makes SFML happy). Build is...
