#15 Won't Compile (linux)

When running make (after running qmake), I get this:

I got the (only) tar.bz2 package

3 problems:
1. You don't have the required ginac installed.
2. qmake is probably setting the wrong kde includes & libs
(unless you're really using 3.1)
3. qmake most likely won't have set the right library flags
for gl.

To fix 2 and 3, open the Makefile and change -I/usr/kde/3.1/
include on the INCPATH line to 3.x where x is your kde
version. Do the same for LIBS Then add -lglut -lGLU -lGL to
the LIBS variable as well. It should then compile.

Without have seen the code : ginac/ginac.h: No such file or directory

-> missing header ;)
