|
|
I would like to reinstall my Gentoo system, switching from 32bit to 64bit. However, normally when I reinstalled gentoo, I use a chroot install from the AltInstall Manual.
The question is, will this also work when installing (compiling) 64bit packages in a chroot running from a 32bit (gentoo) environment? _________________ | 1.6Ghz atom N270 | adopt an unanswerd post | a nice way to post a config file |

i am just missing the point here. why can't you boot 64bit live cd and install from there? |

The only solution is then cross-compiling a stage3.
But you will have so many headaches, that booting a 64 bit live CD is the easier solution. _________________ Kind regards,

An amd64 kernel built with IA32 emulation can run x86 programs. You could boot the amd64 LiveCD, rearrange your partitions to make room for an amd64 installation, then chroot into your regular system and run your programs from there. This would let you run your regular X server and programs with all their files, but also keep the text consoles attached to the amd64 CD, which you could then use to install a new amd64 system in the background. This does require adequate space to have both systems temporarily installed side-by-side. Using LVM makes this easier, but if the existing system is not LVM, the change can still be done. |

Hello everyone!
Basically this thread answers my question, but I just want the confirmation from experts.
I wanted to do the same thing as Sade. I followed this link to make 64bit kernel and everything went well. The system booted. However, I'm wondering if it's possible to compile kernel modules - particularly nvidia-drivers? Because the kernel is 64bit, I would have to compile 64bit kernel driver, but there are also some libraries in nvidia-drivers that won't work with my 32bit system. Also, this requires recompilation of xorg-server and who knows what else. Is this correct, or there is a way to overcome this?
I've already given up, because I won't gain much with 64bit system, and the hassel is to big, but for future visitors and for the sake of my education I beg your answer. |
