Pavel Pisa prepares cross toolchains for several architectures as Debian packages. These cross toolchains were prepared according to How to build GNU cross-compilers page.

Installation on Debian/Ubuntu

  • Add APT source:
echo deb unstable main  >/etc/apt/sources.list.d/rtime-debs.list
  • Update list of available packages
apt-get update
  • Install packages from cross-dev section (e.g. using apt-get, aptitude or synaptic)

These packages have not correct dependencies. You need to install libmpfr1ldbl a libgmp3c2 packages manually. Packages are not signed so you will see a warning during installation.

There are packages for GCC, Binutils and Newlib/Glibc for the following architecture

  • arm-elf
  • arm-linux-gnueabi
  • powerpc-elf
  • powerpc-linux-gnu
  • mips-elf
  • msp430 Uniarch devel

Packages are prepared to run on i386 and amd64 architectures.

Installation on Gentoo

emerge -av dpkg

Dpkg complains about missing files, so we create them manually:

touch /var/lib/dpkg/{status,available}
touch /usr/local/bin/update-rc.d
chmod +x /usr/local/bin/update-rc.d

Install any packages you want:

dpkg -i binutils-powerpc-linux-gnu_2.18.0-1_i386.deb  gcc-powerpc-linux-gnu_4.3.2-1_i386.deb
dpkg -i glibc-powerpc-linux-gnu_2.7-1_all.deb

Installation on distributions without dpkg

ar x binutils-powerpc-linux-gnu_2.18.0-1_i386.deb   # Extract Debian package
tar -C / -xvzf data.tar.gz                          # Untar data from the package to the filesystem root
