Subject: [PATCH] libtracefs: Update libtracefs.pc when version changes
Date: Fri, 9 Apr 2021 17:57:38 -0400 [thread overview]
Message-ID: <20210409175738.101366dd@gandalf.local.home> (raw)
From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>
When the libtracefs version changes, the libtracefs.pc needs to be updated,
otherwise it may install the wrong version number.
