====== TL;DR ======

<code>
curl -s https://github.com/matthiasr/summon-arm-toolchain/raw/master/summon-arm-toolchain | /bin/sh
git clone git://github.com/matthiasr/r0ket.git r0ket
cd r0ket/firmware
cp SECRETS SECRETS.release
PATH=$HOME/arm/bin:$PATH ./release-all
</code>


Another working example:
<code>
git clone https://github.com/esden/summon-arm-toolchain.git
cd summon-arm-toolchain
./summon-arm-toolchain PREFIX=$HOME/arm USE_LINARO=0
...
</code>

gcc-linaro fails to build, and when building by hand he had problems while linking. ratte

====== Toolchain ======

I adapted a [[https://github.com/matthiasr/summon-arm-toolchain|Script]] for building a GNU binutils/GCC/Newlib/GDB toolchain. It should be portable. //gmp//, //mpfr// and //mpc// need not be installed.

The script will build //binutils//, //gcc//, the //newlib// C library, //gcc// again and //gdb// into ~/arm by default.

====== r0ket firmware ======

Currently there is one issue with the mainline r0ket firmware; in some circumstances the linker for loadables fails to find some library functions gcc inserts on variable initialisations or something. I've found that linking with gcc instead fixes this problem. A fixed version is available from [[https://github.com/matthiasr/r0ket|my repo]] [[https://github.com/r0ket/r0ket/pull/20|for now]].
