Subject: [dpdk-dev] [RFC PATCH] RFC build: prototype support for ARM builds
Date: Tue, 19 Dec 2017 10:53:38 +0000	[thread overview]
Message-ID: <20171219105338.198727-1-bruce.richardson@intel.com> (raw)

Add some skeleton files to enable compiling for ARM target. This has been
tested by doing a cross-compile for armv8-a type using the linaro gcc
toolchain.

	meson arm-build --cross-file aarch64_cross.txt
	ninja -C arm-build

where aarch64_cross.txt contained the following

	[binaries]
	c = 'aarch64-linux-gnu-gcc'
	cpp = 'aarch64-linux-gnu-cpp'
	ar = 'aarch64-linux-gnu-ar'

	[host_machine]
	system = 'linux'
	cpu_family = 'aarch64'
	cpu = 'armv8-a'
	endian = 'little'

It is hoped that those working on arm architecture can use this as a baseline
to add arm support - both native compiled and cross-compiled - to the meson
build.
