you have to install crystal space and cel. delete that you have installed and put this in your console but you need to have those packages first :
cvs zlib1g-dev bison-1.35 gcc-3.2 g++-3.2 cpp-3.2 jam libmng-dev libmikmod2-dev libogg-dev libvorbis-dev zlib1g-dev libpng3-dev libjpeg62-dev python2.3-dev  xlibmesa3-gl (or xlibmesa-gl-dev and xlibmesa-glu-dev, it depends of your xfree86 version).
if you have all of that do :

cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/crystal login
(press enter when there is password

cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/crystal co -rPRE_THING_FACTORIES CS && cd CS && ./configure CC=gcc-3.2 CXX=g++-3.2 CPP=cpp-3.2 && make all && export CRYSTAL=$PWD && echo \"export CRYSTAL=$PWD\" >> $HOME/.bashrc && cd .. && cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/cel login
(press enter when there is password

cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/cel co -D 2003-05-16 cel && cd cel && export CSCONFPATH=$PWD && ./configure CC=gcc-3.2 CXX=g++-3.2 CPP=cpp-3.2 && jam && export CEL=$PWD && echo \"export CEL=$PWD\" >> $HOME/.bashrc && echo \"export CSCONFPATH=$PWD\" >> $HOME/.bashrc && cd .. && cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/planeshift login
(press enter when there is password

cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/planeshift co -rMB010 planeshift && cd planeshift && ./autogen.sh && ./configure CC=gcc-3.2 CXX=g++-3.2 CPP=cpp-3.2 && jam && cd .. && wget -t0 -c http://heanet.dl.sourceforge.net/sourceforge/planeshift/planeshift.tar.gz && tar -xvzf planeshift.tar.gz planeshift/art

when i do ./walktest, i have :
using GL_ARB_texture_env_combine
using GL_ARB_texture_env_dot3
not using GL_EXT_texture_env_combine
not using GL_EXT_texture_env_dot3

can you explain me that ? I hope it\'s coming from that because i have no errors so i can\'t understand why crystal space lag

I have this error when i have cal3d packages :
*-------------------------------------------------------------------------*

Someone can give me a list of all required package in order to use Crystal Space in OpenGL on a Debian GNU/Linux System ?

I resolved the problem font, it was because I didn\'t have the freefont2 package but my game is always slow and I saw that the crystalspace test and cel test are also slow but I don\'t understand why because I have no errors. Have you an idea ?

no problem with drm and dri. all is ok. I have just problems with planeshift.

I see an other problem when I launch the game :
Warning: Failed to load `freefnt2\'; reason(s):

WARNING: could not load plugin \'crystalspace.font.server.freetype2\'

But it\'s fonts so i don\'t think there is a link between fonts and graphics.

Thanks for your help
