Linker Errors

Good day

I am trying to compile an application using the following tools:

gcc-3.3-23
orbit2-2.6.0-21
orbit2-devel-2.6.0-21
orbitcpp-1.3.5 (from source, not shipped with distro)

on SuSE 8.2. However, I suspect that I am not linking correctly, as my app
compiles to an object (.o) file, but it does not want to link correctly.

Thanks to Murray for suggesting pkg-config, it cut my error file from 134 
lines to 17. Could you please tell me which other libraries I need / must 
link to? I have included my list of ORBit and IDL libraries, as well as an 
extract of my Makefile.

sdr_corba : sdr_corba.o
	g++ sdr_corba.o `pkg-config --cflags --libs ORBit-2.0-cpp` \
	-o sdr_corba 2> linker_errors

Also, (just for interest's sake) using the c backend generates a -skelimpl.c 
file with the --skeleton-impl option, but the cpp backend does not generate 
something similar. Is this correct? And how do I generate files with a .cpp 
extension in stead of .cc?

Best Regards
Johan
