Subject: [Qemu-devel] [PATCH 08/11] trace: rebuild generated-events.o when configuration changes
Date: Thu, 28 Mar 2013 14:25:49 +0100 [thread overview]
Message-ID: <1364477152-26994-9-git-send-email-stefanha@redhat.com> (raw)
In-Reply-To: <1364477152-26994-1-git-send-email-stefanha@redhat.com>
Make sure to rebuild generated-events.o when ./configure options change.
This prevents linker errors when a stale generated-events.o gets linked
with code compiled against fresh headers. For example, try building
with ./configure --enable-trace-backend=stderr followed by ./configure
--enable-trace-backend=dtrace.
