Are there more people having problems building packages on the build machine? I'm getting an "error: failed to init transaction (unable to lock database)" error, or is this related only to my account?

So for the time being I'm not able to update the x86_64 versions of my packages :( If somebody has a bit time left feel free to update them, otherwise I'll do it when it is working again (the packages currently in need are: sakura, ristretto, wxmaxima, and youtube-dl).

This is probably an issue with the RW portion of your chroot. I haven't setup a good way to fully clean this up, because it's all done under sudo. I just killed that for you, to clean it up. you should be good now

Update on this, I was over there last night and the build machine decided it hated us all, and subsequently refuses to boot (looks like hardware to us). Anyhow, just a heads up.

Yeah good call, machine is off. Dead. Finito. I will have to buy new hardware or something soon. For now, it's best if people rely on Andy's pkg_diff and help rebuild other people's packages

But is the converse possible? Can I build x86_64 pkgs from inside Arch32 by chrooting to my arch64 partition?

It's not possible. You can't chroot to a x86_64 system, from a 32bit system. Regards, Mateusz.

Um, sure you can, if your hardware runs 64bit. I *think* there are some issues with kernel modules, but if you use 'linux64' in addition to chroot, all your bases should be covered

Right. But by '32bit system' I meant '32bit kernel + 32bit userland'.

NB: I have a 64bit environment running Arch32, with a core Arch64 installed in another partition mounted as /mnt/arch64

I tried this: mount --bind /dev /mnt/arch64/dev mount --bind /dev/pts /mnt/arch64/dev/pts mount --bind /dev/shm /mnt/arch64/dev/shm mount -t proc none /mnt/arch64/proc mount -t sysfs none /mnt/arch64/sys linux64 chroot /mnt/arch64

but the latter does not work: I get "chroot: cannot run command `/bin/bash': Exec format error"

Any idea? Or is it really impossible to do this as Mateusz was saying?

Thanks F

I believe it's impossible. 64bit system can run 32bit executables, but not vice versa. A 64bit root would have 64bit executables, so a 32bit system cannot run them. You probably could use Qemu for it though. If you're willing to spare the processing power and RAM needed for emulation. -- Hyperair

I have hardware that was actually bought for Arch 64 building. It's running at my house right now. Currently it's not set up to do anything. If someone has the time and knowhow, I'll give them sudo access to set up any build stuff they want for everyone. We can use this is the meantime. Jason
