your -mcpu=i686 specifically tells gcc to compile for 32-bit cpu you need to use something like
-march=k8 or -mtune=k8 usually http://gcc.gnu.org/onlinedocs/gcc/i386-and-x86_002d64-Options.html the difference between march and mtune is whether it breaks compatability with other CPU's (mtune doesn't) On Thu, Dec 4, 2008 at 10:24, paolo pedaletti <[EMAIL PROTECTED]> wrote: > > Ciao, > sorry for this silly question, but I can't compile kvm-79 for AMD 64bit > > Linux 2.6.27-9-server, ubuntu 8.10 > model name : AMD Athlon(tm) 64 X2 Dual Core Processor 5600+ > > > [EMAIL PROTECTED]:/usr/src/kvm-79# ./configure > Install prefix /usr/local > BIOS directory /usr/local/share/qemu > binary directory /usr/local/bin > Manual directory /usr/local/share/man > ELF interp prefix /usr/gnemul/qemu-%M > Source path /usr/src/kvm-79/qemu > C compiler gcc > Host C compiler gcc > ARCH_CFLAGS -m64 > make make > install install > host CPU x86_64 > host big endian no > target list x86_64-softmmu > gprof enabled no > sparse enabled no > profiler no > static build no > -Werror enabled no > SDL support yes > SDL static link yes > curses support yes > mingw32 support no > Audio drivers oss > Extra audio cards > Mixer emulation no > VNC TLS support no > kqemu support no > kvm support yes > CPU emulation yes > brlapi support no > Documentation no > NPTL support yes > vde support yes > AIO support yes > KVM support yes > > [EMAIL PROTECTED]:/usr/src/kvm-79# make > make -C libkvm > make[1]: Entering directory `/usr/src/kvm-79/libkvm' > gcc -march=i686 -mcpu=i686 -malign-functions=4 -O2 -m64 > -D__x86_64__ -MMD -MF ./.libkvm-x86.d -g -fomit-frame-pointer -Wall > -fno-stack-protector -I /usr/src/kvm-79/kernel/include -c -o > libkvm-x86.o libkvm-x86.c > `-mcpu=' is deprecated.
