Hello there, I'm a software engineer working with MIPS CPU -- octeon. I used to build my projects on my x86 system using a cross-compiled gcc which was built specifically for octeon platform. Recently, I have figured out that gcc 4.4.3 starts to support octeon platform by using a normal x86 gcc with an option "-march=octeon". But it seems not working as I tried several time. I've tried to compile a brand new gcc while not install it. And I also tried installing it. Both ways seem not working as it supposed to. As I'm using gcc to build an octeon target, i got the message below: gcc a.c -march=octeon a.c: 1: error: bad value (octeon) for –march= switch a.c: 1: error: bad value (octeon) for –mtune= switch It seems the option '-march' and '-mtune' won't work with all MIPS series platform. But when I tried replace 'octeon' with 'athlon64' or something else, gcc did it just fine. I was wondering, am i using the option in a wrong way, or it is a bug in fact? Please help me out about how to build octeon target under x86 gcc with those options, thanks very much. Best Regards, Zhuo Liu -- ------------------------------------- Best Regards, Liu Zhuo
