--- Comment #5 from Peter Bergner <bergner at gcc dot gnu.org> --- (In reply to Matthias Klose from comment #0) > cc1: warning: will not generate 'power7' instructions because assembler > lacks 'power7' support > cc1: error: '-msecure-plt' not supported by your assembler So this is the error you get if the gcc configure doesn't find your cross binutils. Is the install dir of your cross binutils on your PATH? If it is, do the binaries have powerpc64-linux-gnu-* names, which your gcc configure is expecting? Can you attach the output of your configure?
