Undefined Reference Error

I am trying the install hydra-7.3 for the first time. I used the make and checkinstall command and both of them gave me the following output.

A bump for the move to Programming Talk.

I guess I need to know how to program then. Have you got any suggestions? I am instructed in learning C++ and Perl. Do you know any forums I can goto?:p

Usually that means you haven't linked all the correct libraries, or have attempted to link them in the wrong order (the subsidiary library must normally go after the module that calls it - unless you use library start / end groups)
