Subject: [PATCH lttng-ust v2] Move include directive from CFLAGS to LOCAL_CPPFLAGS in examples' Makefiles
Date: Tue, 28 May 2013 18:19:18 -0400 [thread overview]
Message-ID: <1369779558-20747-1-git-send-email-jeremie.galarneau__23228.440542198$1369779606$gmane$org@efficios.com> (raw)
In-Reply-To: <1369771309-1773-1-git-send-email-jeremie.galarneau@efficios.com>
The use of LOCAL_* flags and override directives ensures that the build
succeeds even if the user explicitly overrides CFLAGS/CPPFLAGS/LDFLAGS.
Fixes #537
