Good C++ game programming library?

[cmpgk1024]

Does anyone know of a good C++ game programming library? I've heard Allegro is good but I couldn't figure out how to install it, and I'm not sure what other libraries there are out there.

Allegro isn't really used anymore. Last time I worked in C++ SMFL was looking pretty good, but I never actually used it.

SDL is quite old now, but very widely used. Simon and I used it for the C++ port of VVVVVV:

Thanks! I'll try them out and see which one works best for me.
