From mboxrd@z Thu Jan 1 00:00:00 1970 From: Thomas De Schampheleire Date: Wed, 23 Nov 2011 14:59:20 +0100 Subject: [Buildroot] [PATCH 1 of 2 v3] Makefile.package.in: add utility functions find*clauses and notfirstword In-Reply-To: References: Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net This patch adds a few utility functions to Makefile.package.in. Functions finddirclauses and findfileclauses help in building a find command that skips a set of directories and performs operations on a set of files. This pattern can for example be used to keep certain files or directories from being stripped, or to remove certain files from a package installation. The notfirstword function is the inverse of the 'firstword' function in make: it returns all but the first word. Signed-off-by: Thomas De Schampheleire Reviewed-by: Arnout Vandecappelle (Essensium/Mind) --- v3: use -path instead of -wholename; fix a bug in finddirclauses. Thanks, Cam. v2: integrate _cont variants in main find*clauses functions.
