I get this error in Ubuntu Lucid (which I did not get in Karmic):

dlopen '/home/wesley/.doom3/base/' 
failed: version `GCC_4.2.0' not found 
(required by /usr/lib/

I only assume its from gcc in Lucid being a higher version: gcc (Ubuntu 4.4.3-4ubuntu5) 4.4.3. I have build-essentials installed as well.

I tried to symlink the missing lib without success. Can anyone help me out to get this working?

That error message means that your file ( was linked against the GCC_4.2.0 version of, but the version of that shared lib you've got doesn't support that. I'd guess that there's a .deb for lucid that delivers the 4.2 runtime somehow, though I confess that's it's very surprising that the newer version is not backwards-compatible. The ubuntu gang may have made a mistake. Recompiling/linking may be your best option.

thanks for the idea to get the .deb, I found it here: – invert Jul 22 '10 at 18:41
Also needed dependency cpp-4.2, I'm not too sure how to link it to the older 4.2 version, can I do it without affect the rest of my system? – invert Jul 22 '10 at 19:01
