[fpc-pascal]Getting pascal code to link with C code

This problem is under linux OS.
Maybe someone has an insight on a problem that I am having
trying to get a shared library created by Free Pascal
to be callable in code by GNU C.
If libraries do not work under Free Pascal, then I would like to link
in the object file that is created by the PPC386 compiler.
I am using FPC1.0.2. It indicates in the help text of the compiler that
the -CD switch is not supported. The -CS option is not recognized by
PPC386.
Imagine compiling the following test.pp file:
library test;
uses funcunit ; (all functions inside unit are cdecl declarations)
exports
testfunc1, testfunc2 ;
end.
*********************
Now compile the unit into a library: ppc386 -CD -g -P -Sd -Op2 test.pp
This creates a libtest.so file that is statically linked.
I do not believe it is a library with position independent code.
*********************
Now, I could use gcc -ltest to link this into a GNU C compiled program,
but upon calling the external function
in the library, I get an exception thrown and the process is ended.
Any ideas on getting pascal code linked into C programs? Either using
.so shared library or linking .o file directly.
Thanks,
Mark Diener
