Help with Undefined symbols error

I am using a fairly large software package (that presumably worked for the creator). I am getting an Undefined symbols error and all the files are object files. I don't know where to start with sorting out this error.

Here is what I did leading up to this error. (The file I am compiling into an executable is called ChainMaker.cpp)

I first entered

Code:

 make ChainMaker

This returned a bunch of errors that had to do with the #include statements. It seems the author was using #include <file_name> when he should have been using #include "file_name". Once I got rid of all those errors I got an error dealing with an undefined function so I defined the function. Now when I do

Code:

make ChainMaker

I get probably over 100 lines of error messages that basically chain off of each other:

Code:

EDIT: I forgot I was in the C forum - can a moderator move this to the C++ forum? Sorry!
