Undefined reference to ...

I'm trying to write a utility for making compressible homogeneous turbulent box flow. To achieve that change turbGen.H and turbGen.C have to be modified. Since I don't want to modify them, I have copied them in my user directory/application/utility/cboxTurb and changed their name to cturbGen.H and cturbGen.C. As it comes out cturbGen.H is being used correctly but when it wants to define the functions from cturbGen.C compiler complains:

undefined reference to `Foam::cturbGen::cturbGen...`

How should I make it understand where is the cturbGen.C file? should the "turbGen.dep" be changed in the Foam directory?

@Mahdi..

Hi, can you post the whole error message?

Actually this is the problem, no matter what I write in my ctubGen.C, it compiles without any problem which means wmake is not using my file at all, however I have added the header in my main file which is cboxTurb.C
