Cross Compiler Build x86_64 Host arm1176jzf-s

[Thomas D. Dean]

I want to develop on an x86_64 system for the Raspberry Pi.

I will use -static, but, for now, ...

int main() {
   fprintf(stderr,"Hello, world, from c.\n");
   return 0;
}

What version of gcc supports my arm1176jzf-s? (Raspberry Pi)?

This appears to work, however, I have not tested on the Raspberry Pi.
