This is a quick and dirty HOWTO on how to build an arm-none-eabi G++ toolchain This work is based on http://www.hermann-uwe.de/blog/building-an-arm-cross-toolchain-with-binutils-gcc-newlib-and-gdb-from-source

1. Build binutils

apt-get source binutils
pushd binutils-2.19.1
debian/rules patch
mkdir build && pushd build
../configure --prefix=/tmp/arm --target=arm-none-eabi --disable-werror
make
make install
popd

2. Build base GCC

apt-get install gcc-4.3-source
make -f /usr/src/gcc-4.3/rules.source patch-source
pushd src
mkdir build && pushd build
# This command line came from ecos's toolchain
../configure --target=arm-none-eabi --prefix=/tmp/arm --with-newlib --enable-languages=c --disable-__cxa_atexit --enable-threads --without-headers --disable-shared
make all-gcc
make install-gcc
popd

3. Build newlib

apt-get source newlib
pushd newlib-1.17.0
debian/rules patch
mkdir src/build
pushd src/build
../configure --target=arm-none-eabi --prefix=/tmp/arm --enable-interwork --enable-multilib --disable-nls
make
make install
popd

4. Build final GCC

pushd src
mkdir build-final && pushd build-final
../configure --target=arm-none-eabi --prefix=/tmp/arm --with-newlib --enable-languages=c,c++ --disable-__cxa_atexit --enable-threads --without-headers --disable-shared
make
make install
popd
