Re: [gentoo-ppc-user] crosscompiling x86 and ppc

[Christoph Wegener]

Hi,

just a note for the crossdev scripts. Please have a look at the output of
crossdev-status.sh. afaik building i686-crosscompile tools on ppc is not
tested yet. so i guess you will have to investigate the details of the
crossbuild process.
