Subject: [PATCH 01/30] xfsprogs: fix automatic dependency generation
Date: Wed, 30 Oct 2013 15:30:52 +1100	[thread overview]
Message-ID: <1383107481-28937-2-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1383107481-28937-1-git-send-email-david@fromorbit.com>

From: Dave Chinner <dchinner@redhat.com>

Adding are removing a header file does not result in dependency
regeneration like it should. make clean will rebuild the
dependencies, but a normal make won't. Fix it.

 # dependency build is automatic, relies on gcc -MM to generate.

+# This is a bit messy. It regenerates the depenencies on each build so
+# that we catch files being added and removed. There are other ways of doing
+# this (e.g. per-file dependency files) but that requires more in-depth changes
+# to the build system. Compile time is not an issue for us, so the
+# rebuild on every make invocation isn't a problem we need to care about. Just
+# do it silently so it doesn't make the build unnecessarily noisy.
