C++ "mangles" function names to express the argument types as well.   
GNU "nm -C" will reverse this, so when you see:

... the symbol name in the file is *not* "scm_init_test".  Run this  
command without the "-C" to see what the real symbol name is.

If you add

  extern "C" void scm_init_test();

before the definition I think everything will work.
