Simpler linking on linux

I was trying to solve a linking issue with cg when i noticed the linking in torque is super weird

looks like it makes a macro for every gl function that calls a binding function that calls getprocaddress to find each function at runtime.. im not sure why that is exactly but in an effort to simplify things i commented most of the lines out for the macros and instead just included GL/gl.h and GL/glu.h files and linked libGL

also i dont have to statically link GLU anymore either, it works fine

here are some of the relavant changes:


in GLCoreFunc.h i commented everything out EXCEPT:

//torque vertex buffer extension
GL_FUNCTION(GLboolean, glAvailableVertexBufferEXT, (void), return GL_FALSE; )
GL_FUNCTION(GLint, glAllocateVertexBufferEXT, (GLsizei size, GLint format, GLboolean preserve), return 0; )
GL_FUNCTION(void*, glLockVertexBufferEXT, (GLint handle, GLsizei size), return NULL; )
GL_FUNCTION(void, glUnlockVertexBufferEXT, (GLint handle), return; )
GL_FUNCTION(void, glSetVertexBufferEXT, (GLint handle), return; )
GL_FUNCTION(void, glOffsetVertexBufferEXT, (GLint handle, GLuint offset), return; )
GL_FUNCTION(void, glFillVertexBufferEXT, (GLint handle, GLint first, GLsizei count), return; )
GL_FUNCTION(void, glFreeVertexBufferEXT, (GLint handle), return; )


and put these lines up at the very top:

#define GL_GLEXT_PROTOTYPES
#include
#include


also GLExtFunc.h

i commented everything out and put:

#define GL_GLEXT_PROTOTYPES
#include
#include


also GLUFunct.h i put:
#define GL_GLEXT_PROTOTYPES
#include
#include


then in mk/conf.UNIX.mk i changed these lines near the bottom to be:

LINK.LIBS.GENERAL = $(LINK.LIBS.VORBIS) -lGL -lGLU -L/usr/X11R6/lib -lSDL -lpthread -ldl # -lefence

LINK.LIBS.TOOLS = $(LINK.LIBS.VORBIS) -lGL -lGLU -L/usr/X11R6/lib -lSDL -lpthread -ldl # -lefence


notice there is no static linking
also i added GL

i think the wacky linking was probably for windows, so if you want to compile for both you should probably put some sorta #ifdef stuff in there for if its linux only, then comment out everything
