error code on target machine.

I created a custom error code file on my development machine and included in my build.  Is there a way to access this custom error code file on my target??

I know the directory struct is different on the target and made the mistake of hard coding in the path on my devellopment machine.  What I'm trying to do is print out the custom error if and when the test encounters one.  I could create a custom error code.txt then look for the right error code then send it to the print...which is what I do on the development machine but how is it done on a target??
