I was hoping somebody who understands the system might be able to offer some advice. The problem I'm having is that when I try to link my object files together with "-lglut32 -lglu32 -lopengl32" I get messages stating that there are "undefined reference"(s) to "_glBegin", amonst other symbols. Searching through the archives I've spotted a message stating that this means I'm compiling with the wrong headers (The symbols should be of the form _glBegin AT 4'). It's at this point that I've lost the thread. My code contains "#include " and doing a 'find / -name glut.h' only shows the one file located in /usr/include/GL. Similarly doing the same find for gl.h gives me one in /usr/include/GL and one in /usr/include/w32api/GL. My compile command is "gcc -c " My link command is "gcc -o
