Arrr. Same problem here at startup: segfault in glXGetFBConfigAttribSGIX. A= =20 simple test case is the following: pyotr@nox:~% cat test.c int main() {} pyotr@nox:~% cc -o test test.c -L/usr/local/lib -lSDL -lGL pyotr@nox:~% ./test zsh: segmentation fault (core dumped) ./test Then I attempted to switch the arguments around... pyotr@nox:~% cc -o test test.c -L/usr/local/lib -lGL -lSDL pyotr@nox:~% ./test pyotr@nox:~% Voila! (Admittedly much to my surprise ;)) So then I changed the Makefile to use these libraries: -lGLU -lSDL -lSDL_gf= x.=20 Result: a perfectly working ./lennardjones. The only minor issue is that it= =20 presented me with exactly one option: pyotr@nox:~/temp/lennard-jones-gas-3d% ./lennardjones Current pixel depth: 32 Available Modes 0 =3D> 3840 x 1200 Select your preferred video mode: So apparently I prefer mode 0 :D. It run fine (and smooth) though. It is clear something goes wrong during the runtime linking process, which= =20 this library order works around. The actual problem is still a mystery to m= e.=20 It might be worthwhile to post a bugreport on the nvnews.net FreeBSD forum. Best regards, Pieter de Goeje
