Subject: [PATCH 15/15] perf data: Add doc when no conversion support compiled
Date: Fri, 28 Jul 2017 17:00:21 -0300 [thread overview]
Message-ID: <20170728200021.11389-16-acme@kernel.org> (raw)
In-Reply-To: <20170728200021.11389-1-acme@kernel.org>
From: Geneviève Bastien <gbastien@versatic.net>
This adds documentation on the environment variables needed to the
message telling that no conversion support is compiled in.
Committer testing:
$ make -C tools/perf install
$ perf data convert --all --to-ctf myctftrace
No conversion support compiled in. perf should be compiled with environment variables LIBBABELTRACE=1 and LIBBABELTRACE_DIR=/path/to/libbabeltrace/
$
