I'm currently running Ubuntu 13.10 amd64. Of course, Ubuntu is now multiarch, which means I have many libs 32 bit copy for compatibility with 32 bit binaries. For example, I can run the 32 bit version of Wine, or native games like Xonotic without issues.
When it comes to fs2_open, which "official" binaries only exist as i686 on linux, the game crashes on startup with this error :
/home/loris/FreeSpace 2 beta/fs2_open_3.7.1_i686: error while loading shared libraries: libSDL-1.2.so.0: cannot open shared object file: No such file or directory
This is not a problem for me as long as I always use x86_64 builds, but has something broken multiarch compatibility ?
