Hello,

I would like write my own class to extend icoFoam.
The class is defined in deflection.H and deflection.C, which are in the same directory as the solver. I included deflection.C in Make/files.
That works fines and everything compiles as long as I dont want to call any member functions of that class. If i call one of them it returns
> In function 'main':
> :undefined reference to 'main::deflection::test()'

I assume, I need to inclucde some command in Make/options, but I couldn't figure out which one.

thank you
Markus
