mesa/opengl/i'm not too smart

[tarrou]

you guys helped me so much yesterday, i hoped i could impose with another question. i'm trying to start programming on linux with opengl but, i'm painfully new at linux and don't know much about what files neeed to be where, and having a voodoo banshee card probably doesn't help. suse 8 comes with mesa so i've got that on there and glut.h is where it should be but i don't have gl or glu anywhere. lots of people have been talking about gl files being somewhere around /usr/X11R6/include but i don't have any gl header files in there, at least not as .h could someone dumb down normal instructions enough to get me going?

one more thing, i figured the mesa that came with suse didn't have the libraries so i downloaded the tar for them from mesa3d and i know how to extract the files but setting up things i'm not so good at. so maybe that's my problem?

Well this is a makefile which we use at school for programming grpahics in opengl and c ..... so it has some dirs there where files should be.. i have yet to set up open gl or glut or gl on this machine yet.... I will be doing so in the next few days....

#
# a simple Makefile to compile a single file program using the Mesa library
# this file uses the defaults for make, where possible
#

GL_INCDIR = /usr/include/GL
GL_LIBDIR = /usr/lib

# the location of the X11 libraries
XLIBS=-L/usr/X11R6/lib -lXmu -lXext -lX11 -lXi -lSM -lICE -lXt
# the location of the Mesa (OpenGL) libraries
GL_LIBS = -L$(GL_LIBDIR) -lglut -lGLU -lGL -lm $(XLIBS)

LIBS=$(GL_LIBS)

PROG=hello

CFILES=$(PROG).c
OFILES=$(PROG).o

CC=gcc

CPPFLAGS=-I$(GL_INCDIR)
CFLAGS=-Wall -O -g
LDFLAGS=$(GL_LIBS)


all: $(PROG)

clean:
-rm -f *.o $(PROG)

#$(PROG): $(OFILES)
# $(CC) $(LDFLAGS) $(OFILES) -o $@ $(LIBS)

ok, i got it to use gl.h etc but when i try to compile it gives me compile errors for every function i call
/tmp/ccRuUbq0.o(.text+0xf): undefined reference to `glClear'
/tmp/ccRuUbq0.o(.text+0x29): undefined reference to `glColor3f'
and so forth. what does this mean?

[rage2001]

I have never seen those errors.. I am not an experienced opengl programmer... tjhis is my first course.... but that make file is what we use to compile out code... it makes the object file...

in there u see the word hello ..... thatst he name of the c program trying to compile... then once it makes the file (if complied withut errors) we type the name: hello

and the file runs

thsoe errors I am not sure about... its late here.. I can take a look in my book tommorrow... see if I can come up with anything

that would be great. what video card do you use? would that make any difference? this is so frustrating...!
