Hello.

I'm trying to run Left 4 Dead 2 by Steam on my gentoo (architecture x86_64).
Another games (Rochard) running fine. I run Steam by optirun (Optimus system on my notebook).

When I try to run L4D2, I get:
Code:

$ optirun ./hl2.sh
Failed to load the launcher (libSDL2-2.0.so.0: wrong ELF class: ELFCLASS64)


I guess that its problem with libraries on 32/64 bit system, but I don't know how to resolve this problem.

Check how ABI_X86 is set for media-libs/libsdl2 (eg. in `eix media-libs/libsdl2` you can see it near the end of the line); I think 32 might be unset (thus -32), you should try toggling that. (You can for example set abi_x86_32 USE flag on it with package.use).

libsdl2 currently does not have multilib support unless you use some hacky overlays

Ah, right, I need to have eix split out that information or run eix without checking overlay; thank you for detailing that.
