bonjour,
j'entreprend actuellement d'apprendre l'utilisation de crystal space, le motyeur 3d temps réel open source.
J'ai télécharger sur le site
http://www.crystalspace3d.org/main/CELstart#Downloads
le CELstart en version linux 64bits
http://www.crystalspace3d.org/downloads/contrib/celstart-1.2.1-linux-x86_64.tar.bz2
cependant si j'essaie de lancer le test de walktest j'ai cette erreur

 ./walktest_static 
./walktest_static: error while loading shared libraries: libCgGL.so: cannot open shared object file: No such file or directory

le fichier en question est a coté du programme walktest, dois je le mettre à un endroit spécifique ?
merci

les bibliothèques partagées sont habituellement, je crois, dans /usr/lib
Si tu n'as pas envie de polluer ce répertoire, essaye de te renseigner sur la variable d'environnement LD_LIBRARY_PATH (ce sont peut-être des tirets et non des underscores, je n'ai pas de machine Linux sous la main)

Bonjour,

# yum provides \*libCgGL.so

te donnera le nom du paquetage à installer fournissant cette bibliothèque, rangée dans le bon répertoire (typiquement /usr/lib64/), plutôt que de l'avoir "à côté".

ok merci j'ai installé du coup cette librairie

et c bon !!

Je sens que cela vas être packagé bientot tout cela...

Tu devras ajouter ce paquet à un BuildRequires: lib3ds-devel dans le spec (par exemple)

ok je veux bien m'y mettreà le mettre sous forme de package
mais déjà j'essaie de le faire fonctionner et après je prendrais du temps pour apprendre à packager un programme
il me manque encore ça "OpenGL development libraries" mais je ne sais pas comment le trouver dans les dépôts
voici quelques librairies dont j'ai eu besoin pour le moment

yum install perl-devel

yum install libX11-devel

yum install libXxf86vm-devel.x86_64 

yum install zlib-devel

yum install libpng-devel

yum install libjpeg-devel

yum install cal3d*

yum install lib3ds

yum install lib3ds-devel

yum install libmng-devel

yum install cegui

yum install caca*

Justement tu aurais plus interet à utiliser un spec, cela permettra de mieux comprendre comment fontionne la compilation.

Je pense que tu peux avoir besoin du paquet Cg surtout si tu utilises une carte nVidia plutot récente.

j'ai installé ça

yum install mesa-libGL-devel

suivant les conseils reçu sur le forum de crystal space

http://www.crystalspace3d.org/forum/index.php/topic,1700.0.html

et j'ai ce problème quand je veux installer le paquet cg

mais ça fonctionne sans cette librairie !!!!!!!!!!!!!!!
ceci dit j'ai cette erreur donc tu dois avoir raison
