Cross-compiling for the Raspberry Pi

Compiling DUNE directly on the Raspberry Pi is possible, but soon becomes tedious, as it takes a while. Luckily there is an alternative, cross-compiling. The Raspberry Pi has an available toolchain at GitHub, but it uses a too old version of the gcc compiler, and therefore it will not compile DUNE. The solution to this, is to use the cross-compiler environment that is made for LSTS Glued.

• Install required packages

sudo apt-get install docker.io

• Clone Glued from github

git clone https://github.com/LSTS/glued.git

• Run docker shell for the build system

cd glued/docker && sudo make shell

• Create build configuration for mariner-01

​ ./mkconfig.bash mariner-01

• Compile system image for mariner-01

​./mksystem.bash lctr-rpi/mariner-01.bash

• Create cross-compilation toolchain

./pktoolchain.bash lctr-rpi/mariner-01.bash

• Leave docker enviroment

exit

• Make directory for pibuild
• cmake
• make
