Re: Weird Torcs error

Hi Evgenios

Is this all output of torcs -l, there is missing a lot of stuff (vorbis, 
openal, parts of torcs, ...)?

Can you try to run as root "ldconfig", and then try again, and if that 
not helps restart the system? Does this help?

What is suspect is that some libs are in /usr/local/lib... and some in 
/usr/lib/x86_64..., this raises the question if this is normal on this 
system or if you have mixed up somehow 64 and 32 bit stuff, e.g my torcs 
-l output is like this and pretty consistent:

I suggest performing this experiment: build TORCS from fresh extracted 
sources into your home directory and run it from there (this way you 
have not to fight with permissions/root):
1. Make sure that your environment variables are empty, check "echo 
$MAKE_DEFAULT" and "echo $TORCS_BASE" (you can set them later again for 
robot development if required)
2. Make sure that "echo $CFLAGS", "echo $CPPFLAGS" and "echo $CXXFLAGS" 
are empty or do not contain weird stuff
3. configure with "./configure --prefix=$HOME/torcs_bin"
4. "make", "make install", "make datainstall"
5. start TORCS with "~/torcs_bin/bin/torcs" (or wherever it has been 
placed).

Best regards

Bernhard
