Re: Fwd: how to compile kvm 64 bit
Ciao Hollis, I don't see arch=, cpu=, nor i686 anywhere in the libkvm build scripts. Could you have a shell alias or some other strangeness on your system that is adding those i686 options? yes, it was true... TANK YOU! some old vars that I used to use on another old platform. thanks again... -- /* Paolo Pedaletti, * [EMAIL PROTECTED] www.pedaletti.it */ -- To unsubscribe from this list: send the line unsubscribe kvm in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
Re: Fwd: how to compile kvm 64 bit
Ciao Malinka, your -mcpu=i686 specifically tells gcc to compile for 32-bit cpu you need to use something like -march=k8 or -mtune=k8 usually ok, I can understand it, but I thought that it was enough to run ./compile to obtain the correct Makefile with the right cpu-option [EMAIL PROTECTED]:/usr/src/kvm-79# ./configure Source path /usr/src/kvm-79/qemu C compilergcc Host C compiler gcc ARCH_CFLAGS -m64 make make install install host CPU x86_64 host big endian no target list x86_64-softmmu so ./compile detect the right cpu/options [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 but the Makefile is wrong do I do something wrong? Is it necessary to do something different? thank you -- Paolo Pedaletti -- To unsubscribe from this list: send the line unsubscribe kvm in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
