Error: could not find function

Dear All,

Pfff... found my stupid error!!!! :-)
And because of the fact that this is the 'novice' list and I realy did not
find the answer on the inet, here it is... so we all can have a bit fun about
my error....

What I was overlooking was the pre-processing from c++ instead of c,
but I was thinking in the wrong direction e.q. I thought it had to do
with the syntax in my code-file, the answer from the man pages:

the actual file extension 'c'
tells the compiler/linker to compile from actual c-code instead of c++.

For any given input file, the file name suffix determines what kind of
compilation is done:

file.c
C source code which must be preprocessed.

And YES, I had a filename extension .cpp!!!!!!!!!!! Whoehaa!!

Thanks ALL for helping me out.

Greetz, dawizz.
