Test the Linux Game Publishing demos...

[icculus]

LGP was pretty good about shipping free demos for their games, and the Internet Archive has them all (demos.linuxgamepublishing.com redirects there).

We should test all these and see what the status is; at least Majesty has a C++ ABI issue that makes Mesa not work where forcing the software renderer fixes it.

(Don't forget to add them to the Compatibility Matrix!)

Worth noting that most (all?) of these games ship with their own copy of libSDL-1.2.so.0 and an rpath to find it, and this seems to override LD_LIBRARY_PATH, so you'll have to overwrite the included SDL with sdl12-compat.

I can't get ballistics to load OpenGL, even with real SDL 1.2. Might be a 32-bit thing. I don't know. This sounds like the sort of thing @sulix could figure out more quickly than me.

Postal 2 has the C++/Mesa conflict nonsense. I'll try it on Nvidia drivers.

I has a super-quick look at this, and couldn't get OpenGL to load either. The game seems to be doing a lot of SDL_GL_LoadLibrary() (with a bunch of custom logic for finding the path to a libGL.so implementation — you can override some of it with the -g option, but that always fails for me), and SDL_GL_GetProcAddress before a window is created. In theory, this shouldn't be a problem, but something's clearly up. The game uses a lot of C++/STL, as well, which doesn't bode well. Though, given even the non-C++-y nVidia drivers are failing, though, it might be something more sinister.

strace informs me that the -g option wants the directory containing libGL.so, not the library filename, but I still couldn't coerce it once I figured that out.

I removed or renamed all of *.so files under lib1 and lib2 except for ssl libs, it then loaded opengl for me on my centos 6.10 i686-linux.

[icculus]

Can we mark that one as working, then...?

[icculus]

Honestly, Candy Cruncher and Majesty are the only two I've tried that didn't have Mesa-vs-C++ issues (even using OpenGL through SDL2's render API), and a lot of these are a struggle to start at all. Maybe this is a waste of time and we should just close this until someone reports a specific incompatibility.

I second that.

For future reference: setting environment variable force_direct_glx_context=true (for Mesa, see src/util/driconf.h) lets Ballistics demo to get to main menu (but it then crashes while loading a race).
