PS3 32 to 64

[leon_73]

Hi all,

I'm pokeing on my ps3 just to see what can I do with it...

Just intalled a brand new gentoo using the stage4-32 .... Now I've tried to compile a new kernel (reiserfs was missing ) and I decided to compile it as 64 bit kernel but I noticed that if I enable it, I get the following error:

Probably it would be easiest to install a full 64 bit setup. Compiling 64 bit code on a 32 bit arch is usually considered cross compiling, which is somewhat of a pain to deal with (you'd need to install another set of compilers, etc).

The 32bit-userland has a compiler capable of compiling 64bit output. And it's provided with the stage4. To compile a 64bit kernel on a 32bit userland, the easiest way is to set the cross compiler in the top level makefile of /usr/src/linux, like so:

CROSS_COMPILE ?= powerpc64-unknown-linux-gnu-

You very likely need to run a make mrproper before trying to recompile, so be sure to back up your .config.

As a side note, kboot does not support reiserfs. So if you plan to use reiser, you should create a /boot partition with not only the kernels and ramdisks but also an etc/kboot.conf.

Also, be certain you use one of the ps3 kernel sources ebuilds in the cell overlay unless you really know what you are doing.
