torcs-devel Mailing List for TORCS - The Open Racing Car Simulator

Hi,

after a long struggle, I finally managed to install TORCS in a custom
directory on a Linux *server* (Fedora 13). All files appear to be present (
I compared my custom install to standard install on another Linux machine).
However, when I run the executable (located in ~/myTorcsInstall/bin/) I get
the following error:

freeglut (/home/user/myTorcsInstall/lib/torcs/torcs-bin): failed to open
display ''

Interestingly enough, this also happens when I run TORCS in text-only mode
(i.e. ./torcs -T ). I tried re-installing it, but the problem doesn't seem
to go away. I have the following packages installed:

freeglut-2.6.0-5.fc13.x86_64
freeglut-devel-2.6.0-5.fc13.x86_64

Any suggestions are highly appreciated.

I think you have to set the following environment variable

export LD_LIBRARY_PATH=/path/to/your/plib/folder

then when TORCS runs it looks for any libraries in LD_LIBRARY_PATH folder
also.

Hello,

I am trying to install TORCS on a Linux machine, but I have no root access.
I used the --prefix option of configure to install it in my home directory,
but there is a problem with the dependencies (more specifically plib). Plib
was installed in my home directory using the same method, but TORCS doesn't
see it. Is there a way I can change the search path to include plib? Should
I create a symbolic link to the plib folder and where should I place it? Any
assistance is highly appreciated.

Thanks,
Miroslav

I have compiled TORCS 1.3.1 under OpenSolaris 2009.06. I suggest to apply
following patches to the TORCS source code.
