static linking of cgi

I would like to static link the cgicc library. I try this with
	g++ -O2 -L/usr/lib/mysql/ -lmysqlclient /usr/lib/libcgicc.a select.o WebDB.o -o select

But then I get a lot of messages like:
	WebDB.o: In function `WebDB::DisplayParameters(char const*, char const*)':
	/home/cecil/zzz/WebDB.cpp:60: undefined reference to `cgicc::HTMLElement::set(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'

What am I doing wrong?
