That's correct output ...

Your expectations are incorrect (probably influenced by your
experience with Win32 DLL model, which is very different from all
other UNIXes (except AIX)).

You need to specify platform (I'll assume Linux/x86_64).

You can get behaviour similar to Win32 by linking the shared library
with -Bsymbolic linker flag (prefix it with -Wl, when using 'gcc'
or 'g++'), or by localizing CommonElement::m_static with a linker
version script (info ld -> Scripts -> VERSION).
