how to provide the defines from one header to another?

Hello,

I ran into the following problem:
I have implemented an API, consisting of C-Api, Manager, BaseClass and the concrete working classes derived from the BaseClass. One of this "concrete" class includes the first header file header1.h and loads its .lib file. I can communicate with the concrete Class only via C-Api with the second header file header2.h. Within the concrete class I use the define constants (

Code:

---

#define SOME_CONSTANT

---

) of the header1 without problems. However, if I include the second header into the third one header3.h, then I'm not able to use the defines from the first header anymore.

Is there a way of solving this problem?


best regards,

vanselm

It is not clear how you "included" your heades... however, why not include header1.h into header3.h?

I don't want to include header1 into header3 because I would like to separate the class of header3 from the vendor specific API in header1. So that I can use devices of different vendors over my Api in header2. (See my modified problem description in first post)
