I think these are relevant: $ zgrep -i ia32 /proc/config.gz CONFIG_IA32_EMULATION=y CONFIG_IA32_AOUT=y > > > In order to get a 64 > > > bit kernel a have to set CFLAGS=-march=k8 > > > > Your CFLAGS in make.conf don't affect your kernel, normally. > > Didn't really think so either.

The only thing I can't think of at this point is something from the gentoo cross compile howto from vapier that may or may not apply: "If you want to cross compile a kernel, do this: make ARCH=hppa CROSS_COMPILE=hppa2.0-unknown-linux-gnu-" So, you may want to configure, make, and install your kernel like: make ARCH=x86_64 menuconfig make ARCH=x86_64 make ARCH=x86_64 install (You don't need a CROSS_COMPILE prefix since gcc should work fine.) -- Boyd Stephen Smith Jr. [EMAIL PROTECTED] ICQ: 514984 YM/AIM: DaTwinkDaddy -- gentoo-user@gentoo.org mailing list
