Question

I am trying to get OpenGL and Glut running on Eclipse Linux FC13.

After spending two days on it, I admit that help is needed. On FC13 Eclipse, I see
/usr/include/GL and /usr/include/SDL — so the libs are there. I started Eclipse, and then tried to run a simple program on it, just like suggested here. However, two things were missing in those steps:

1. Callisto could not be installed —
   nothing was found from the
   repository
2. GCC C++ Linker is not found anywhere
   for Eclipse 3.5.2.

When trying to run the program, I see this error:

Program does not exist

and sometimes

Binary not found

If I just run the “hello world” it works, but otherwise, those errors happen every time I try to include glut gl or sdl commands.

Here is an excerpt from the compiler error:

make all 
g++ -O2 -g -Wall -fmessage-length=0   -c -o tw.o tw.cpp
tw.cpp: In function ‘void main_loop_function()’:
g++ -o tw tw.o

Yes, apparently the compiler is not able to see the glu, gl, sdl and glut libraries.

Some suggestion on how to fix?

Answer 1

You have to tell the compiler that your program uses additional libraries.

Use the -l argument

g++ -O2 -g -Wall -fmessage-length=0  -lglut -lGL -lGLU -lX11  -c -o tw.o tw.cpp

This should help against unsatisfied link errors.

You can set these in the properties of your Project.
Properties->c/c++ Build->Settings->Tool Settings->Linker
