Re: [Buildroot] [PATCH 1/4] package/libtraceevent: new package

[Andreas Ziegler <br015@umbiko.net>]

Hi Maxime,

libtraceevent and libtracefs are libraries, thus should be positioned 
under "Target packages" -> "Libraries".

Introducing a "Debugging, profiling and benchmark" category here would 
probably be appropriate.

Tested successfully on x86_64 hardware.

Kind regards,
Andreas
