Subject: [ptxdist] [PATCH v2] systemd: add SYSTEMD_CPPFLAGS for local kernel headers
Date: Wed, 26 Nov 2014 13:03:16 +0100 [thread overview]
Message-ID: <1417003396-14336-1-git-send-email-list-09_ptxdist@tqsc.de> (raw)
From: Markus Niebel <Markus.Niebel@tq-group.com>
systemd uses cpp to generate tables for keymappings. Without setting
CPPFLAGS the toolchain headers will be used for generation but
local kernel headers for compilation. This can break compile.
Since CPPFLAGS are implicitly used when calling compiler directly,
we can drop the CFLAGS settings for local kernel headers.
tested with kernel 3.9
changes:
v2: drop SYSTEMD_CFLAGS, add this fact to the comments
