[Clfs-support] Binutils for ARM devices

[Chris Smith]

Hi Michele,

I did this some time ago, but using binutils v2.24 not v2.27.  I built it using the following:

export CLFS_FLOAT=soft
export CLFS_HOST=x86_64-cross-linux-gnu
export CLFS_TARGET=arm-linux-musleabi
export CLFS_ARCH=arm
export CLFS_ARM_ARCH=armv5te

../binutils-2.24/configure \
	--prefix=/usr \
	--build=${CLFS_HOST} \
	--target=${CLFS_TARGET} \
	--host=${CLFS_TARGET} \
	--with-sysroot=/ \
	--disable-nls \
	--disable-multilib

make configure-host
make
make DESTDIR=${TARGET_FS} includedir=${TARGET_DEV_DIR}/usr/include datarootdir=${TARGET_DEV_DIR}/usr/share install

I’m pretty sure this worked okay, but the project was only half finished, and I haven’t touched it for a long time.

Regards,
Chris
