One thing I thought was that perhaps reusing Kbuild would be a good idea, something like: cd tools/ make menuconfig And use all the Kbuild machinery to select needed features, etc. What do you think? It can be a follow up to what you're doing, that is needed anyway, some questions below: > Thanks. > > -- > >From 0f391f0acf39d3b2e85145dce389cbf425cb7cdd Mon Sep 17 00:00:00 2001 > From: Borislav Petkov > Date: Mon, 14 Jun 2010 21:14:15 +0200 > Subject: [PATCH] perf: rewire generic library stuff > > --- > tools/Makefile | 74 +++++ > tools/lib/Makefile | 41 +++ > tools/lib/util/cache.h | 86 ++++++ > tools/lib/util/debugfs.c | 252 +++++++++++++++++ > tools/lib/util/debugfs.h | 31 +++ > tools/lib/util/strbuf.c | 133 +++++++++ > tools/lib/util/strbuf.h | 92 +++++++ > tools/lib/util/types.h | 17 ++ > tools/lib/util/util.h | 282 ++++++++++++++++++++ Will we continue using "util" here?
