Hello Omer

Would help if you tell us what system you were trying to do the building
on.

thanks.

checking for sin in -lm... no
configure: error: Can't find libm. Please check config.log and if you can't
solve the problem send the file to tor...@li... with
the subject "torcs compilation problem"


thanks

Hi Jacobo Reveles,

After reading the config.log file, I think the problem is that ./configure 
didn't found libXrender.

You can search manually for libXrender ('locate libXrender' or 'su - -c 
"updatedb" && locate libXrender' (the last one takes some time)) . If it 
doesn't exists, you can try to install libXrender.

If it does exists, the problem can be the search path. It searches for that 
file in /usr/X11R6/lib. A couple of libs are found in that directory, but it 
could be that libXrender is installed in another directory. If that is the 
case, you can try to set the LDFLAGS enviroment variable. Lets assume that 
libXrender is in /usr/lib. The LDFLAGS environement variabele should then be 
set to " -L/usr/lib ". This can be achieved by the command:

LDFLAGS=" -L/usr/lib " ./configure

Mart

Hi all,

Happy new year to all TORCS users and developpers.
May the 2006 year be as productive as 2005, TORCS is getting
better and better thanks to all the work on code and all the
contributions on tracks and cars :-)
May also 2006 be nice for your personnal life and your familly.

Eric.

Does not matter, it should work in the end crossplattform and on all supported
systems, so the very same code should work on all platforms (Linux, FreeBSD,
Windows, 32/64 bit, little and big endian).

Yes, there was a thread ~1 year ago, and I have a plan in my mind. It will be a
big amount of work, so if you want to help have a look at the README and pick a
task there for the current release (let me know to avoid doubled work), the
networking thing is too big to start with, trust me;-)

Bye, thank you,

Bernhard.

Hello,
I'm Klogus... I'm getting addicted to Torcs! I'm also a linux programmer,
and I'm wondering how network playing could be achieved in this operative
system.
What would be the general scheme? Are there some ideas yet? I could make
some experiment on my LAN.
It would be great! We could organize a real annual championship....

Thank you!=20

Hello,

thanks to all developers for this great game, but you know, people are never 
completely satisfied, so I have two small wishes for next versions.

1. When I drove with keyboard there was no problem, but now I got a wheel and 
I have problem with screensaver. When I go a longer race a screensaver turns 
on during a race. Would it be possible to avoid it? As I know, some video 
player does it with generating some keyevents at some intervals. Maybe torcs 
could do the same, if it gets events from joystick/wheel, it would generate 
keyevents ie every 1 min.

2. I use upper back view (one of driver's view) when I'm driving. The problem 
is, that program doesn't remember camera position. I prefer a longer camera 
distance than is default and I have to set it on every race again. 
When I finish race with some other view (ie F4) and switch it to driver's view 
(F2) in new race then it is ok.

I never heard that before as well. To diagnose you can start TORCS with "torcs
-d", this will give you a backtrace of the crash (requires GDB), that will
perhaps help to diagnose the problem (depends with what switches it was compiled).

>   Version: 0.0.7

Hmm, I just tested with 0.0.8. What happens if you disable the sound completely
in the sound menu, what happens if you use the plib backend? Does this help? Did
you enable texture compression or downscaling, and if yes, which version of plib
is on your system?

What would help as well is:
- OS architecture -> x86 (32bit), AMD/EMT64 (64bit)
- plib version
- plib compile switches if 64bit architecture (requires -fPIC)
- glut/freeglut version
- which 3D card and driver?
- which sound card and driver?

Bye, Bernhard.

I have just installed torcs 1.2.4 from the fedora core rpm's.  I'm 
running torcs on fedora core 4.  The developers have done a great job on 
this simulation.  I am very impressed.

I don't have a problem starting or running the first race.  However, 
every time I try to run a second race, torcs crashes.  I have checked 
the FAQ and didn't see anything that was similar.  Where should I start 
to look for the problem?  The following is the output from the terminal 
when running torcs.

I have an update on the control tutorial, with a new section on
trajectory optimisation - this might be useful for your robot.

http://www.idiap.ch/~dimitrak/simu/index.html

here is the source for the demo:

http://www.idiap.ch/~dimitrak/software/trajectory/optimise_road.cc

After compling, run it with

optimise_road 1000 0.01 >trajectory.out 2>learning.out

The trajectory.out file will be split into 3 pairs of 2 columns. One
pair is the x,y coordinates of the track's left side, the other the
track's right side, and the 3rd the coordinates of the trajectory.

The learning.out file will haeve the following columns
iteration, cost, penalty, mean squared derivative, mean derivative (the
last one is not very meaningful mathematically in terms of convergence
though).

If the penalty remains at 0 then the algorithm probably has not
converged, because most of the optimal solutions tend to touch the sides
of the road.

OK, have fun
