This file gives a short overview of the required compiler packages to build the LXR sourcecode on linux with the included makefiles. You will need the ARM GCC compiler and the AVR GCC compiler as well as the AVR libc.


GNU Tools for ARM Embedded Processors

https://launchpad.net/gcc-arm-embedded


For Ubuntu 10.04/12.04/13.04 32/64-bit user, PPA is available at https://launchpad.net/~terry.guo/+archive/gcc-arm-embedded.

otherwise you can download the 32bit binaries here https://launchpad.net/gcc-arm-embedded/4.8/4.8-2014-q1-update/+download/gcc-arm-none-eabi-4_8-2014q1-20140314-linux.tar.bz2


Installing the ARM GCC binaries0

download the binary package: wget https://launchpad.net/gcc-arm-embedded/4.8/4.8-2014-q1-update/+download/gcc-arm-none-eabi-4_8-2014q1-20140314-linux.tar.bz2

extract it: tar xvjf gcc-arm-none-eabi-4_8-2014q1-20140314-linux.tar.bz2

move it to /opt/ARM: sudo mv gcc-arm-none-eabi-4_8-2014q1 /opt/ARM

include it permanently in your PATH variable echo "PATH=$PATH:/opt/ARM/bin" >> ~/.bashrc

IMPORTANT! for x64 systems you have to install the 32-bit version of libc6 or you will get an 'arm-none-eabi-gcc: not found' error: sudo apt-get install libc6-dev-i386


AVR GCC

sudo apt-get install gcc-avr avr-libc

Building the firmware

Now you should be ready to go. to build the firmware, go to the LXR folder containing this file and type: make firmware

Now you should now find a new FIRMWARE.BIN file in the 'firmware image' subfolder


Thanks a lot to Patrick Dowling and Andrew Shakinovsky for their code contributions!
