Subject: [PATCH] i2c-tools: enable static use of libi2c
Date: Tue, 16 Jun 2015 04:01:19 +0200 [thread overview]
Message-ID: <1434420079-3029-1-git-send-email-wsa@the-dreams.de> (raw)
From: Wolfram Sang <wsa+renesas@sang-engineering.com>
When debugging embedded systems, it is often nice to simply TFTP the
desired i2ctool to the target without the hazzle of dealing with shared
libs. Using -static is overkill, too, so let's add a switch which will
only link functions from libi2c statically.
