[Mesa3d-users] newbie problem accessing header files

[marty moore <remoorsed@ya...>]

 Hi,
 I'm just learning mesa-6.4, using gcc-3.4.3.22, on scientific linux(rh enterprise 4).
 
 I've followed the installation instructions, and verified that the headers and library files are install in /usr/local/include/GL and /usr/local/lib.
 When I try to compile the hello.c example program or  the demo program rain.cxx, I get compiler errors about undefined references to gl/glu/glut commands used in the program.  If I vary the #include <GL/gl.h> statement to #include <gl.h>, I get an error that gl.h wasn't found, which seems to indicate that the gl, glu, and glut header files were found when I used the <GL/gl.h> format.  I get the same errors when I use the full path name in the include statements.
 The problem seems similar to needing the "using namespace std " statement to access the <stdlib> or <iostream> header files.
 
 Is there a namespace I should be using, or do these errors mean that mesa3d isn't properly installed?
 
 any ideas would be appreciated,
 Marty

You should always have the "GL/" part in your #includes.  It's a 
standard OpenGL convention.

Are you using -I/usr/local/include when you compile?  You may be 
inadvertantly getting gl.h and glu.h from /usr/include/GL/.

Otherwise, a small test program and the exact output from the compiler 
would be helpful.
