Hmm, I could imagine a quick and dirty solution, but did not try it:
- Record a screen macro with a screen macro recorder to start the race 
(this starts it up)
- If your robot discovers that it wants to restart do an "exit" in your 
robot (this shuts it down), in the robots shutdown function you could do 
the same.
- Now create a shell/batch script/application which does:
1. do while "torcs is running" (so hang here till the process is gone)
1. execute start macro
2. sleep a moment
3. goto 1

Another solution would be to modify these 2 things (should be easy as well):
- Add in the car->ctrl struct a field where your robot can ask the 
simulation to terminate
- Evaluate this in the raceengine, set up a state transition (modify the 
race state machine in src/libs/raceengineclient/racestate.cpp)

Hope this helps, please let me know how you solved it finally.

Hi

Do you have an alias set for make or other tools set, which commands get 
executed (for the output you required something like make -d I think), 
do you use a parallel build (then try just ordinary "make", maybe there 
is another parallel build problem)?

Is your environment hardened somehow to avoid linking shared libraries 
from the home directory?

Are the libraries (.so files) here in place for the linker or are they 
missing (check /home/developer/Projects/torcs-1.3.2/export/lib).

Hi Alessandro

How did you build torcs exactly, did you follow the instructions, do you 
have from old TORCS version MAKE_DEFAULT or TORCS_BASE set (environment 
variables, should not be set in a "default build" scenario)? Which Linux 
distro do you use, do you have a special ld_library_path?

Does it solve your problem when you (re)install openal/openalut and its 
devel packages, and build TORCS again (configure should catch this 
tough...)?

Best regards

Bernhard

Hello all,

    I'm getting errors during "make", even if the configure script has been run successfully.
There's the error_log as attachment.

Thank you in advance for suggestions and your attention
