Subject: [Buildroot] [PATCH v3 13/18] python2: generate reproducible .pyc
Date: Wed, 23 Nov 2016 12:08:13 +0100	[thread overview]
Message-ID: <1479899298-14655-14-git-send-email-jezz@sysmic.org> (raw)
In-Reply-To: <1479899298-14655-1-git-send-email-jezz@sysmic.org>

.pyc files contain modification time of .py source. In order to make
build reproducible, we fix modification time of all .py before to
compile .pyc files.

This work was sponsored by `BA Robotic Systems'.
