C++ for paparazzi

First uninstall binutils-arm, newlib-arm, paparazzi-arm7, gcc-arm. This packets can easily found e.g. by selecting source/paparazzi in synaptic.

Install gnuarm-toolchain from www.gnuarm.com. Find under Files->Binaries->GCC-x.x the right tool chain for your platform. I've used this.

This link told me how to set up the path. I've added: export PATH=$PATH:/opt/gnuarm-3.4.3/bin/ in ~/.profile to have my installation under /opt in the path.
