Ok, I did this.

Yep, so linking works... but... no output is given by the pascal
procedure. If I do some output in C after the pascal call, it also is
not executed. The binary simply returns to commandline and the exit
code of the programm is 103 (is this something pascalisch?).

If I use Fernandos example, it works indeed! But he moves output to
C.

I could do that, but I don't know if our project uses pascal
libraries internally, I just have an API to work with and I'm the
lucky one who has to write the perl and the python modules... Oh, one
thing I know: it is completely object oriented inside! Is this also a
problem (there are some object libs in the rtl path)?

But I will talk back to the pascal developer, perhaps he only uses
self-written stuff...

But on the other hand: There must be a way to link the pascal stuff
into my C stuff, or not?

Thanxx for the quick help!
