Hi all I put together a package with my favourite tracks from the track generator and I set up the 2014 championship, it is ready to sign in. Visit www.torcs.org for details. I wish you all and your families a happy new year. Kind regards Bernhard |

Hi Sergio Basically you can take 1.3.4/5, there are just these things to consider: - The car used in the tutorial does not exist anymore (so you have to choose another one or to "resurrect" it, e.g from an old package or CVS) - Some types have been changed from "char*" to "const char*" - http://www.berniw.org/trb/forum/showthread.php?topicid=3421 So the code differences will be minimal, the main difference will be the different car, like you would have decided to take another car to go through the tutorial. Regarding the installation I would recommend this (see chapter 10.5): - http://www.berniw.org/trb/events/rules_view.php?viewrulesid=18#c10_5 (installation from full package into home, you still need to set then $TORCS_BASE and $MAKE_DEFAULT properly to be able to develop your robot outside the ordinary source tree) I guess I will update the tutorial for 1.4 then (but 1.4 is still pretty far away, first 1.3.6 has to be done).

Hi Sergio TORCS 1.2.4 was a long time ago, so it needs some care to make it build, short: - regenerate (or edit) configure script - update some includes (<xxx.h> to <xxx>, changed from gcc 3.x to 4.x). Some more details here: http://sourceforge.net/p/torcs/mailman/message/30193739/ Kind regards Bernhard On 12/30/2013 07:41 PM, Sergio wrote: > > > ---------- Forwarded message ---------- > From: *Sergio* <ser...@gm... <mailto:ser...@gm...>> > Date: 2013/12/30 > Subject: Torcs installation > To: tor...@li... > <mailto:tor...@li...> > > > Hello.

Hi Evgenios You are welcome. So TORCS is building and running fine now, great to hear. I guess you reinstalled the same Ubuntu Version as you had before, so this case will remain a mystery then...

Well, thanks for your help, in the end I re-installed ubuntu and It worked flawlessly so I am at a loss as well at what I did wrong. Thanks everyone for your time here! |

Hi Tom No, looks good, no idea... Recap: - The command line shows -lpng -> ok - There is actually a png library -> ok - The symbol is defined -> ok So the last thing what comes to my mind is that something is broken (toochain, environment, libs, ...). Could you try to reinstall the png lib and png devel packages, and then try to reconfigure/rebuild torcs (make distclean, ./configure, make)?

Hello Tom,
one thing you could do is find where is the missing library :
on your test program you run ldd to find in which path is located libpng
ldd png_test | grep libpng
and look if the path of this lib is well referenced in the compile paths of
Torcs :
-L/usr/lib -L/usr/local/lib

Hi Tom
Hm, no idea. What you can check if the symbol is available in the png
libs, and what your default library is (usually there are multiple
versions installed, e.g. 1.2 and 1.5):
cd /usr
find . -name "libpn*"
-> list of candidates
check with "nm -D path/libpng.so | grep create_info_struct" ("path" is
meant as placeholder here)
Is the symbol defined there?
You could try to export as well "-Wl,--verbose" in CPPFLAGS, CXXFLAGS
and CFLAGS, and rerun configure/make to see the linker output during the
build.
Please report back when you have more information or a solution.
Kind regards
Bernhard
