If your main program is coded in C++ while your shared library is of C,  you have to demangle the C++ symbols. To confirm your shared library symbols, use 'nm test.so' to see what symbols are available in fact. Or you could confirm what symbols your main program requests actually, use 'nm main.out', too.

Waiting for further information.
