Hello,

I just get a fresh red hat distribution with my opteron, and I have some
problem during ./configure of my project. The result is:

"configure:2567: error: C compiler cannot create executables"

in fact, it's because the gcc doesn't know the arch and cpu type
"x86_64"

$ gcc -pipe -ftemplate-depth-24 -march=x86_64 test.c

cc1plus: bad value (x86_64) for -march= switch
cc1plus: bad value (x86_64) for -mcpu= switch

but '/bin/arch' returns x86_64

What should I do?

$uname -a

Linux Ryzom 2.4.20-9.2smp #1 SMP Thu Apr 10 11:54:33 EDT 2003 x86_64
x86_64 x86_64 GNU/Linux

$gcc --version

gcc (GCC) 3.2.2 20030313 (Red Hat Linux 3.2.2-10)
