Cross compilers

Pavel Pisa prepares cross toolchains for several architectures as Debian packages.

To use these packages on Debian/Ubuntu/... system follow these steps:

• Add APT source:

echo deb ftp://rtime.felk.cvut.cz/debian 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

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 gcc-powerpc-elf_4.3.2-1_i386.deb
