You must include "/usr/lib/c++rt0.o" near the front of your "ld" command
line when creating C++ shared libraries. E.g.,
ld -Bshareable -o libfoo.so.1.0 /usr/lib/c++rt0.o *.o
If you are using the standard FreeBSD makefiles (<bsd.lib.mk>), you can
accomplish this by defining the CPLUSPLUSLIB make variable.
