That '-x c++' flag to the linkage run (the second) may be your
problem.  It tells gxx that all the filenames following it are C++
source files.  I.e. it things objs/main.o is a c++ source file, which
obviously it isn't.

You shouldn't usually need the '-x c++' flag at all. Just be sure you
use a standard filename convention for your source files. '.c++' is
not an expected filename for C++ sources. It's not even a legal DOS
filename, on top of that. Use '.cxx' or '.cpp' instead. Or '.cc' if
you want to keep a bit closer to Unix conventions.
