Debian seems to have some unique problems in the way they handle AMD64 compared to other distributions. I would not trust what you read there, they make it much more complicated than it really is.

You just need a 64bit capable cross compiler to compile the kernel, which is not that difficult to build from sources. You can also find binaries for that at ftp://ftp.suse.com/pub/suse/x86_64/supplementary/CrossTools/8.1-i386/ (usable with rpm2cpio on non RPM distributions). Then you can cross compile the kernel in the normal way with make ARCH=x86_64 CROSS_COMPILE=x86_64-linux- A few programs (namely iptables and ipsec tools) need to be used as 64bit programs because the 32bit emulation doesn't work for them. ipchains works though. > Should 2.4.25 be able to run 64bit, or are is it more of an all or nothing > type thing? 2.4.25 supports 64bit just fine. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
