To make it work, I also included all the libraries contained in Makefile.am file of ospf process in my own Makefile.am file.<br> Even though it successfully compiles after the adaptation of functions from area_router.cc, it gives "undefined reference" errors while linking some certain functions such as SingleVarRW::initialize(int const&, Element*), SingleVarRW::~SingleVarRW(), PolicyTags::PolicyTags(Element const&), IfMgrIfTree::find_interface(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&) const, IfMgrXrlMirror::~IfMgrXrlMirror(), etc. along with some others.<br>
Why doesn't it work even though I exactly use the same libraries as ospf does ?<br></blockquote><br></div></div>You need to post your linker error output so someone can help you in more detail.<br><br>The link order is important, and you need to be sure you're using the same automake primaries for a C++ program target to link.<br>
