Bison complains about undefined reference of my own data type

I am a newbie in bison, so I don't know all the secrets. I used for a while a
standard example with its own data type and now I want to include my own. I
included the header file, but the compiler throws me an exception for
undefined reference. However, this is not true, the implementation of the
function of my data types class are in the cpp file. The explanation I can
give is the following.

The example's data type was in a header file, let's say example.h. The
implementation was in the same .h file, so it worked. My data type's
implementation is in a separate .cpp file. So, there is some problem for
bison to recognize .cpp files? Maybe, because it is in C and not C++ ?

Do you now if there is a solution? The cpp can't get into the h, because
they are already built, so I can't just change them all, it's a pretty big
project.

Thank you,
Stratis
