I had a look at this, but I have no idea how I can fix this. To me it looks like it is conflicting with what is in the clang and what is in the SDK. I have no clue how to force it using the same include file. Any help appreciated

[kockie69]

Ok, I think I already have a solution provided by another user.

This one is fixed now. Compiled locally on toolchain with success
