Ok. That's because there are two "hive" variants. the building system should use either one of them (but not both at the same time). I didn't get the error before because I was just building a module (that speeds up the development). Such errors only happen on a full build. Fixed. As I did a git rebase (in order to have something that we could upstream later), you'll need to use this procedure to update: $ git remote update $ git reset --hard origin/atomisp_v2 There's no need to clean your last build. Just run: $ make -j4 And it should build fine this time. > > Not sure if I can help with that. Sounds like we have to remove > definitions - which I might be able to do.

Intel seems to use some code generator internally. Basically, for each specific device, it can remove/add/change things. Don't mind about that. For us, we're seeing just the generated code and working to simplify it and making it more generic. > But with some hints I'm of course willing to give it a shot.

Yeah, is is fine now. Thanks! Thanks, Mauro
