Hi Michael,
thanks for the input.
i get it compiled with using crosstool-ng & this link: https://wiki.linaro.org/WorkingGroups/ToolChain/Using/CrosstoolNg
so i'm happy for now :)

See `config.log' for more details.
Hi Bruno. It looks like you're trying to build a cross compiler. You'll also need a 'sysroot' which supplies the headers, libraries, and startup files for the target itself.
You could also try the pre-built cross compilers at https://launchpad.net/~linaro-maintainers/+archive/toolchain. These have the latest Linaro goodness and target the Pandaboard.
