The files look as follows:

Yes, and LDFLAGS should then be used in test_t rule. But, both by convention and by implicit rules implementation, the C++ compiler is contained in CXX variable (and not CC, which is supposed to be C compiler) with its compile flags being stored in CXXFLAGS variable. By properly setting CPPFLAGS (preprocessor flags (-I, -D, ...) for both CC and CXX) , CXXFLAGS, and LDFLAGS you can build test_t purely by using implicit rules. Cheers, Leon
