Thanks, I cleaned up my system, and at least I could compile existing modules.
What I then found out is, that if you take the local data (which is allocated by hal_malloc) and you make a global variable out of it (to avoid pointers) then the same error message as shown below appears. I went back to allocate data by hal_malloc and now it works.
