Toolchain
Where to get a ARM toolchain?
You can find here more or less recent toolchains.
Download the .tar.bz2 file.
Uncompress it # tar -xvjf arm-2009q3-67-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2
I suggest to create a file name /home/$USER/.cross_compile that contains:
export ARCH=arm export CROSS_COMPILE=/home/georges/tools/toolchain/arm-2009q3/bin/arm-none-linux-gnueabi
Each time, you need to build a software with this toolchain, you just have to source it.
If you are building Android, you can find it here: prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/.
