This build system has been tested on Mac OS X 10.6 (should also work on 10.5). Small modifications may be needed in order to make it work with other platforms.

Note: If you have previously built a toolchain of another version, out of the same builder directory, make sure to do the following first before building with newer sources:

make clean

You will need to have GCC, make, binutils and latex installed on your machine to compile all of this. You can get all of these on Mac OS X, by just installing the Apple Developer Tools which are free here.

If you haven’t installed gmp or mpfr, install them first:

sudo make install-deps

NOTE: The first time you run this, it will attempt to download the tarball for the CodeSourcery sources, which may take some time. It should not need to do this again for later steps (files needed will be extracted).

These instructions should now also work on Ubuntu Linux, provided the following packages have been installed prior to attempting the build:

sudo apt-get install curl flex bison libgmp3-dev libmpfr-dev autoconf build-essential libncurses5-dev libmpc-dev

Next prep for building the main toolchain:

mkdir -p $HOME/arm-cs-tools/bin

export PATH=$HOME/arm-cs-tools/bin:$PATH

Next build the toolchain:

make install-cross

This should build the compiler, newlib, gdb, etc.. and install them all into a directory called arm-cs-tools in your home directory. If you want to install to another location, feel free to change the export lines and to adjust the definitions at the top of the Makefile.

Keep in mind that the Makefile does install at the end of each build.

Once you’re done, you’ll likely want to add the path where the compiler was installed to to your .bash_profile, .zshrc, etc..:

export PATH=$HOME/arm-cs-tools/bin:$PATH
