From afdb545b2847d2a922ee202775998d4658900fec Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Sat, 1 Jul 2017 16:31:07 +0200 Subject: [PATCH] tools: new tool to filter the output of make Add brmake, a small script that redirects the build output log to a file, keeping just Buildroot's own messages, with the date+time added at the start of the line. We need to unbuffer the output of make so that, when the script is interrupted (SIGINT, ^C), there is no lingering output not yet digested by the logger loop. Signed-off-by: "Yann E.
