I got confused.
I have a /usr/lib/libobjc.a, come with FreeBSD 4.6.
And a /usr/local/lib/gcc-lib/i386.../3.0.4/libobjc.a,
come with GCC 3.0.4.
If I remove the /usr/lib/libobjc.a, it will complain no objc.
If I add the gcc-lib into the libraries, it can't links to C++ library.
Which one should I use ?
