Subject: [PATCH 4.14 34/41] ARC: build: Dont set CROSS_COMPILE in archs Makefile
Date: Thu, 18 Oct 2018 19:54:49 +0200 [thread overview]
Message-ID: <20181018175422.671965719@linuxfoundation.org> (raw)
In-Reply-To: <20181018175416.718399607@linuxfoundation.org>
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alexey Brodkin <abrodkin@synopsys.com>
commit 40660f1fcee8d524a60b5101538e42b1f39f106d upstream.
There's not much sense in doing that because if user or
his build-system didn't set CROSS_COMPILE we still may
very well make incorrect guess.
But as it turned out setting CROSS_COMPILE is not as harmless
as one may think: with recent changes that implemented automatic
discovery of __host__ gcc features unconditional setup of
CROSS_COMPILE leads to failures on execution of "make xxx_defconfig"
with absent cross-compiler, for more info see [1].
Set CROSS_COMPILE as well gets in the way if we want only to build
.dtb's (again with absent cross-compiler which is not really needed
for building .dtb's), see [2].
Note, we had to change LIBGCC assignment type from ":=" to "="
so that is is resolved on its usage, otherwise if it is resolved
at declaration time with missing CROSS_COMPILE we're getting this
error message from host GCC:
| gcc: error: unrecognized command line option -mmedium-calls
| gcc: error: unrecognized command line option -mno-sdata
