• Install the prerequisites:

sudo apt-get install git-core gcc make

For a 64bit Linux you might also need lib32z1 because the gcc-arm-none-eabi package in /Tools is a 32bit binary:

sudo apt-get install lib32z1

• Checkout TinyG2 source as of now, master branch is very outdated. There's no stable version available, but the brave souls may try edge branch.

mkdir -p ~/src/github.com/synthetos
cd ~/src/github.com/synthetos
git clone https://github.com/synthetos/g2 g2
cd ./g2
git checkout edge

To clone the edge branch directly you can run the following command:

git clone -b edge git@github.com:synthetos/g2.git

• Build the sources:

cd g2/TinyG2
make

If you get the error which breaks at include <type_traits> you probably use an incompatible version of gcc-arm-none-eabi. At this time, to compile G2 it's best to use the gcc-arm-none-eabi binaries which are downloaded in the Tools directory or downgrade to 4.9.1.

Do not use -j option when running make. It will break everything. See #11 for the details. The output is ./bin/gShield/gShield_flash.bin.

After compiling, you will likely want to flash the firmware.

• Flashing G2 with Linux.
• Flashing G2 with OSX.
