I'have added a test case to DUnit Test project in embarcadero c++ builder 2010. I can compile it fine but the linker fails saying "unresolved external" to a method in an .obj file from original project. If I add the .obj file to DUnit project it works fine. However I don't want to do it as there are huge number of .obj files in the original project and it will be a pain to add .obj files each time you want to test a new class. Is there a way to point the linker to search directories to look in for .obj files and get them from there. ( I'm not using the command line, but the c++ builder 2010 IDE).
