How do I link header files
 

I've been trying to compile viscosityModel in the User folder.

typing wmake it couldn't find one header file. viscosityModel.H includes viscosityLaw.H.

I added the path in the include: #include "/home/marvin/OpenFOAM/marvin-2.1.1/src/transportModels/viscoelastic/viscoelasticLaws/viscoelasticLaw/viscoelasticLaw.H"

Then it began compiling. No error any more about that error. Later another header file wasn't found.
Message:
viscoelasticLaws/viscoelasticLaw/newViscoelasticLaw.C:28:31: schwerwiegender Mistake: viscoelasticModel.H: File or Path not found. End of compiling
make: *** [Make/linux64GccDPOpt/newViscoelasticLaw.o] Mistake 1
(Translated to English)

I believe I don't need that long path name:confused:. My Problem is, that I didn't get so far how wmake knows how to find the header files correctly and I don't know what that all has to do with "files" and "options" in the Make-directory.:confused:

If anyone has a clue I would be very grateful.
