I am not shure what you mean, but if you want to say, that elxr is not the GNU linker, that's right, these are Greenhills logs. Perhaps I did not point out clearly.

Ah, I see, this is because of a non standard section type, not suported by Greenhills. Is there a relation to the problem, that the linker complained about different section types for .debug_info or .debug_abbrev?

[Lehner, Michael] 
I'll try that.

Are there any solutions fort he other errors where symbols I really can't find?
