kdevelop -> my file won't link!

Hi,

I have these files

Megaman01.cpp
MScene.cpp
main.c
globals.c

with their respective header files (*.h)

They compile, the app runs, it is an openGL / QtOpenGL app.

But,

MScene.cpp needs this :

#include "globals.c" // !!
to work, because otherwise it says, *AFTER COMPILING THE FILES* :

mscene.o(.text+0x223): In function `MScene::readTextures()':
: undefined reference to `LoadTGA(Texture*, char const*)'

However, it does recognize LoadTGA's prototype, which is defined in
globals.h!! And globals.h is imported by mscene.h, which is where it
recognizes its from. It is the function *body* that is not found, so how
can this be? I used autoconf and then ./configure which worke,d an dlike I
said it only errors *after the files ahve been compiled* it is not a syntax
or parse error.

Like I said this worked, by including "globals.c" explicitly. This is not
pretty as you all know.

But after adding some functionality, I needed a glu function.
MScene.cpp needs and can include this :

#include <GL/glu.h>
naturally.
I link against the GLU library in my project settings, and this shows up in
the Makefile as one of the ldflags.

However, even by including this, I get the same error when trying to make :

 "mscene.o(.text+0x7eb): In function `MScene::resizeGL(int, int)':
: undefined reference to `gluPerspective'

Here is a full dump of my make output :

What could possibly cause MScene.cpp to not accept the functions whoms
prototypes it does find? I will emphasize again it is not a syntax or parse
error: after the compile it doesn't seem to find the bodies of the
functions, *unless I specifically include them in MScene.cpp*

Thanks very much for any possible help. Sorry for the length, I wanted to be
clear.
