When you write -lxxx, your compiler look for libxxx.a or libxxx.so

I don't use Boost.System, but according to its documentation:
http://www.boost.org/doc/libs/1_38_0/libs/system/doc/reference.html#Deprecated-names
You should use get_generic_category() instead of get_posix_category()

You can also use the command nm to verify if 'yyy' function is in 'xxx' library:
nm -C /usr/lib/libxxx.a | grep yyy

IMHO, get_posix_category is in libboost_system.a, but not in
libboost_system-mt.a
