Hello all! I have ArchLinux i686 version, but I'm trying to compile an x86_64 kernel... And you've guessed... Not supported by the ArchLinux stock gcc / binutils... I've done the "raining" dance, by trying to compile my own gcc / binutils, but it didn't "rain" (I mean it didn't work)... Any pointers? Thanks, Ciprian. P.S.: Is there any good reason for which there isn't even a separate package of gcc that is able to do this? (I've read the bug from one year ago, but no good reason was specified...) P.P.S.: I'm missing Debian...

Arch users generally prefer a clean 32bit/64bit chroot to a "dirty" system and have therefore developed tools to make chroot creation really convenient. You should try it too - get the devtools and try "mkarchroot". -- Sven-Hendrik

About the reason I've read it and somehow understood it. Also mkarchroot is quite nice (in fact the reason I'm struggling with kernel compilation is for a Vserver deployment)... But back to the problem at hand: I cannot use a chrooted Linux, because in order to use x86_64 packages I need a x86_64 enabled kernel on my laptop (which I don't). So actually I need to cross-compile the kernel. Now I've seen that in the default repository we have gcc for crosscompiling for arm. Why not one for x86_64? Anyway thanks for the pointer of mkarchroot! (It would help me in deployment of virtual servers.) Ciprian.

Why do you want to build the kernel ? Arch already provides it ! All packages are provided in both i686 and x86_64 http://allanmcrae.com/2009/06/using-an-x86_64-kernel-on-an-i686-userland/

Good question. 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?

I haven't found one... I've already searched the AUR for "gcc" and the only entries that resemble what I need are: * http://aur.archlinux.org/packages.php?ID=28545 (gcc-multilib); * http://aur.archlinux.org/packages.php?ID=31547 (cross32-gcc); But both of them are for crosscompiling an i686 from a x86_64, while I need the reverse. Could you please give me the exact URL from those packages? Thanks, Ciprian.
