Subject: [PATCH 3/5] kernel-shark: Change default libraries install location
Date: Tue,  5 Jan 2021 17:54:51 +0200	[thread overview]
Message-ID: <20210105155453.41228-4-y.karadz@gmail.com> (raw)
In-Reply-To: <20210105155453.41228-1-y.karadz@gmail.com>

The default installation path for the KernelShark libraries changes from
/usr/local/lib/kernelshark/ to /usr/local/lib64 (or /usr/local/lib on
32 but systems). This is done in order to be consistent with the install
locations of libtraceevent, libtracefs and libtracecmd.
