Hi, I am trying to compile some C++ code and link it to a couple of C++ libraries (Informix c++ libs). However, I get 'undefined references' for every object from the libraries I use. The code compiles fine though. Could anybody give me some suggestions on how to test the libraries/what to be aware of when linking/what might cause the problem? I'm using gcc 3.3.1 and all librarie are in place & specified in the makefile. Thanks alot! Martin
