libpq++ how to

[Kyle Waters]

I'm trying to use libpq++ and I have it installed on a Debian box(yeah) 
and a Fedora box.  I'm trying to compile the examples that come with 
Debian and I get the following error:

test001.cxx:(.text+0x1aa): undefined reference to 
`pqxx::connection_base::protocol_version() const'

on both machines.  I haven't ever done database stuff with c++ so I'm 
probably missing something simple.  If someone can point me in the right 
direction for some beginning documentation or tell me what's wrong, I'd 
appreciate it.
