Re: Question about native compiling

If we do our compiles on a G5 is it really a 'native' compile or is it a cross-compile and we're back in the same boat as we were with the x86? Should we use a G4 instead? Thanks for any advice or pointers to other places where I can find information. Do you plan on running the same Ubuntu install (for ppc32) on the 8347e? If not you'll need to be careful to ensure libraries, etc are the same or compatible. - k ___ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
Re: Question about native compiling
Thanks Kumar and everyone else who responded. You've all been a great deal of help and I really appreciate it. We're going to go with the G5. Thanks again. Bruce ___ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded

Thanks for any advice or pointers to other places where I can find information. We use a dual G5 to do the exact same thing. We have a compiler buildt on our target board (Freescale 8280), and on the G5 we make sure that this compiler is being used (by chrooting into a copy of the filesystem used on the target). Then we compile all our apps . Only thing we have to do speciial, is to add --build=powerpc-unknown-linux-gnu --host=powerpc-unknown-linux-gnu to the ./configure cammand line. ___ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
