Getting Wolfenstein (wolf) running in Debian Running games in Linux could be a pain in the ass. Here I tried to install Wolfenstein. Install your software. Probebly it goes to /usr/local/games/wolfenstein. And of course make your openGL working. See the big internet for doing this. If you start your game (./wolf) it will come up with the following error: Wolf 1.1b linux-i386 Jan 17 2002 ----- FS_Startup ----- Current search path: /home/rogier/.wolf/main /usr/local/games/wolfenstein/main/mp_pakmaps0.pk3 (21 files) /usr/local/games/wolfenstein/main/mp_pak2.pk3 (3 files) /usr/local/games/wolfenstein/main/mp_pak1.pk3 (308 files) /usr/local/games/wolfenstein/main/mp_pak0.pk3 (783 files) /usr/local/games/wolfenstein/main/pak0.pk3 (4775 files) /usr/local/games/wolfenstein/main ./wolf.x86/main ---------------------- 5890 files in pk3 files execing default.cfg couldn't exec language.cfg couldn't exec wolfconfig_mp.cfg couldn't exec autoexec.cfg Hunk_Clear: reset the hunk ok Joystick is not active.

So make the link: cd /usr/lib32/ ln -s libGL.so.1 libGL.so
