[PATCHv2 00/36] perf tools: New build framework

[Jiri Olsa]

hi,
I'm following up on latest post from Alexis:
  http://marc.info/?l=linux-kernel&m=141427580405357&w=2

v2 changes:
  - build Makefiles librarized and moved to 'tools/build' [Ingo]
  - several minor fixies [Namhyung]
  - tested on other archs now - x86_64, i386, powerpc
  - moved tools/lib/* under new build framework to show
    that it's possible ;-)
    included traceevent/lockdep maintainers to get the feedback
  - omitted last 2 patches

The patchset is also available in:
  git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
  perf/build

All tests/make tests passed.

Any feedback from ARM guys would be great ;-)


Since it's actually small portion of kbuild that perf needs,
I realized it's actually better to steal it than 'reconfigure'
kbuild to be usable for perf.

Also this patchset is kind of incremental version of the latest:
  perf tools: Add kbuild support into Makefile.kbuild
so it should be easier to review.

NOTE I couldn't find any copyright/credit messages in the kbuild
system, but would be happy to include it if someone suggests one.

The stolen parts are in files:
  Makefile.kbuild
  Build.include

The idea and more details are explained in the 'Documentation/Build'
file. The basic idea is the same as in kbuild system, with some minor
changes to allow for multiple binaries build definitions.

User provides 'Build' files with objects definitions like:
  perf-y += perf.o
  perf-y += builtin-bench.o
  ...

  libperf-y += util/
  ...

and the build framework outputs files:
  perf-in.o
  libperf-in.o

which are then linked into appropriate binaries/libraries.
(perf libperf.a libperf-gtk.so)

Also now we have the full dependency check ((gcc -Wp,-MD,... stuff) and
build command line is stored/checked automatically by the build system.

thanks for comments,
jirka
