Installing the toolchain
Add a .list file in /etc/apt/sources.list.d/ containing : “deb http://emdebian.org/tools/debian jessie main”
Update the public key for this repo with ‘curl http://emdebian.org/tools/debian/emdebian-toolchain-archive.key | sudo apt-key add –‘
Add armhf as foreign architecture by running ‘sudo dpkg –add-architecture armhf‘.
Check correct install with ‘dpkg –print-foreign-architectures‘ which should show ‘armhf‘
Run ‘sudo apt-get update‘ and install the toolchain by running ‘sudo apt-get install crossbuild-essential-armhf‘
/usr/bin should now contain arm-linux-gnueabihf-g++
Emulating armhf with QEMU user-mode emulation
Run ‘sudo apt-get install qemu-user-static‘
In my case running a cross compiled test c++ program (type hello world) caused dynamic library load errors…
You can easily fix this by setting an environment variable, export QEMU_LD_PREFIX=/usr/arm-linux-gnueabihf (or wherever you installed the toolchain) or by building with static linking.
