Compile RTCW source (ftp://ftp.idsoftware.com/idstuff/source/RTCW-SP-GPL.zip).

Error:

}

What may be the result? Linux ubuntu 10.04, acceleration is working.

You’re probably missing an X11 header file.

Look at the lines before the error (it could be 50-100 lines back) and you’ll probably see something like :

cannot find ???.h

Do an “apt-file search” on the “???.h” file to find which Ubuntu package it’s in, and then “apt-get install” that package.

It could be “libxxf86vm-dev” you need.
