Dependencies
You’ll need to use either the Crazyflie VM, install some ARM toolchain or the Bitcraze docker builder image. If you install a toolchain, the arm embedded gcc toolchain is recomended.
Frameworks for unit testing are pulled in as git submodules. To get them when cloning
git clone --recursive https://github.com/bitcraze/lps-node-firmware.git
or if you already have a cloned repo and want the submodules
git submodule init
git submodule update
OS X
brew tap PX4/homebrew-px4
brew install gcc-arm-none-eabi
Debian/Ubuntu linux
Download, extract and put in your path the compiler from https://launchpad.net/gcc-arm-embedded. For example:
mkdir -p ~/opt/
cd ~/opt
wget https://launchpad.net/gcc-arm-embedded/5.0/5-2016-q3-update/+download/gcc-arm-none-eabi-5_4-2016q3-20160926-linux.tar.bz2
tar xvf gcc-arm-none-eabi-5_4-2016q3-20160926-linux.tar.bz2
mv gcc-arm-none-eabi-5_4-2016q3 gcc-arm-none-eabi
rm gcc-arm-none-eabi-5_4-2016q3-20160926-linux.tar.bz2
echo "export PATH=\$PATH:\$HOME/opt/gcc-arm-none-eabi/bin" >> ~/.bashrc
On 64Bit Linux you also need to install some 32Bit libs:
sudo apt-get install libncurses5:i386
If all works you will be able to execute arm-none-eabi-gcc:
$ arm-none-eabi-gcc --version
