opengl unter linux compilieren ?

hmm, jetz hat er zwar die header gefunden, leider findet er die richtigen funktionen nicht

allerdings gibt es kein -l glu oder so ... das findet er nich ... wie kann ich die definition von z.b. der funktion wie gluMainLoop dem compilier beibringen ?
-
mal ganz allgemein, wo finde ich ne liste von den linker files ?
wieso ?
damit ich weis, wie sie heißen, damit ich sie richtig einbinden kann ^^
-
hast du mal
glut32 versucht ?
-
-lGLU, vielleicht auch lglut, kommt drauf an, welche implementation du hast.
kannst mal nachgucken, die sollten unter /usr/lib liegen. libGL* libgl*
