From mboxrd@z Thu Jan 1 00:00:00 1970 From: Thomas De Schampheleire Date: Tue, 29 Jul 2014 23:12:28 +0200 Subject: [Buildroot] [PATCH 01 of 20] pkg-generic: introduce helper function to check for a deprecated variable In-Reply-To: References: Message-ID: <677354152366d6f52f1b.1406668348@localhost> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net This patch introduces a helper check-deprecated-variable, that throws an error when a package defines a deprecated variable. This helps in detecting transition errors when changing the buildroot infrastructures, and also helps users that have created packages not part of mainline buildroot.
