Well the reasons could be multiple: * first of all the real reason is that I want to compile an x86_64 kernel for one of my servers that I want to use as VServer hosting target; but my laptop has ArchLinux i386, and I don't want to either install x86_64 ArchLinux on my laptop, or on the server itself just to be able to compile the kernel; * second cross-compiling is one of the basic operations one should be able to do in an development environment; * third I believe that the real power of OSS / FOS (and therefore also Linux based distributions), is that it allows you the flexibility to customize things to match your liking; furthermore I've switched from Debian (which also provided everything I needed and even more), to ArchLinux (which provides almost everything I need), because I've seen ArchLinux as a more suitable target for experimenting with Linux; (I hope I'm not wrong!) By the way: I'me preparing three custom packages: cross-x86_64-gcc-base, cross-x86_64-binutils, and cross-x86_64-glibc. Anyone interested in them? Any ideeas if someone has already done this?
