I installed tremulous through the ubuntu repositories (game worked fine), decided to try out the TJW stuff. Followed the guide to install it (
http://tremulous.net/forum/index.php?topic=10437.0). Clicking on tremulous.x86 from nautilus or from the app menu results in nothing happening. No error message, no display, the program doesn't even try to run.
Like a noob, I accidently deleted the original tremulous file leaving only the tremulous.x86 file in the folder, but that shouldn't make a difference for running TJW.
BTW, I also tried with mercenariesguild version and same thing. I also remembered to use check "allow executing as an application".
EDIT: (I noticed these errors in terminal)
fixme:exec:SHELL_execute flags ignored: 0x00000500
Z:\usr\lib\tremulous\tremulous.x86: error while loading shared libraries: libopenal.so.0: cannot open shared object file: No such file or directory
