The first thing you should do when you get an 'undefined reference' error
is search your libraries to find out which library that is defined in, and
then link to that library. Probably you need to add '-ldl'. But since you
didn't specify your platform, there's really no way we could know. Did you
try the man pages for 'dlopen', 'dlclose', and 'dlsym'?
