Subject: [PATCH 01/10] perf tools: Compile perf with libperf-in.o instead of libperf.a
Date: Wed, 13 Feb 2019 13:32:37 +0100 [thread overview]
Message-ID: <20190213123246.4015-2-jolsa@kernel.org> (raw)
In-Reply-To: <20190213123246.4015-1-jolsa@kernel.org>
There's no need for perf build to use libperf.a,
we can use directly libperf-in.o.
The libperf.a stays as a target if needed:
$ make libperf.a
...
CC util/pmu.o
CC util/pmu-flex.o
LD util/libperf-in.o
LD libperf-in.o
AR libperf.a
