Linaro embedded toolchain on Ubuntu 64-Bit

Linaro provides a specialized toolchain for embedded (bare metal) development. But after installing, I could not execute the binary:

$ gcc-arm-none-eabi-4_7-2012q4/bin/arm-none-eabi-gcc
-bash: gcc-arm-none-eabi-4_7-2012q4/bin/arm-none-eabi-gcc: No such file or directory

Also ldd claims its not dynamically linked:

$ ldd gcc-arm-none-eabi-4_7-2012q4/bin/arm-none-eabi-gcc
 not a dynamic executable

The truth is: it is dynamically linked, but against 32-Bit libraries. And since I have not yet installed any 32-Bit library, ldd doesn’t work properly. According to the readme, you should install the 32-Bit variant of libc and libncurses. Since Ubuntu is Multi-Arch, you can easily install those libs:

sudo apt-get install libc6:i386 libncurses5:i386

Now you should be able to run the Linaro toolchain on 64-Bit variants of Ubuntu.

  1. For Arch Linux you need to edit /etc/pacman.conf (enable multilib) and install the libs:

    pacman -Syyu
    pacman -S lib32-glibc
