**Maria1505** · 15/04/2007, 23h23

Bonjour pourriez tester ce programme et me dire quelles sont les librairies que je dois inclure pour que mon programme tourne ! Merci bcq

Code :

Sans pouvoir tester (je suis sous linux) je dirais :

-lopengl32 -lglu32 -lglaux -lm

Jc

**BruceBoc** · 16/04/2007, 19h00

C'est quoi "lm" parce que sur windows sa ne me dit rien. Sinon pour le reste sa devrait suffir.

**Laurent Gomila** · 16/04/2007, 19h11

-lm c'est pour lier avec la bibliothèque standard mathématique (ce qu'il y a dans math.h). Parfois y en a besoin, parfois pas. Peut-être que sous Windows il n'y en a pas besoin.

**Maria1505** · 16/04/2007, 20h40

oui j'ai deja essaye ca mais il me donne :

--------------------Configuration: Engrenage - Win32 Debug--------------------
Linking...
LIBCD.lib(wincrt0.obj) : error LNK2001: unresolved external symbol _WinMain@16
Debug/Engrenage.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

Engrenage.exe - 2 error(s), 0 warning(s)

Tu as créé un projet "Application Windows", ton point d'entrée doit donc être WinMain et non main (voir MSDN pour son prototype).
