32-Bit Chroot How-To

[wmcbrine]

I have Kaffeine installed, but it complains that it 'can't connect to the Xserver' whenever I try to open a file.

That's what happens when /tmp isn't mounted in the chroot (mount --bind /tmp /chroot/tmp, or via fstab).

Worse still Kaffeine needs access to kernel drivers to work my TV card - and it can't see these in chroot.

If you mean, it can't see the devices, you need to mount --bind /dev /chroot/dev (see my post above). If you mean it can't see the modules, don't worry; only the kernel needs to see them.

There is a 64Bit version of kaffeine - but all the codecs it needs to play mutimedia files and TV streams are in 32 bit

I'm not familiar with kaffeine, but that doesn't sound right. I can tell you, I run 64-bit MPlayer, VLC and Xine here, and they can play almost everything with only their native (64-bit) codecs.

A bit of googling about no sound from flash with chroot (and esd) led to this:

http://lists.debian.org/debian-amd64.../msg00337.html

To sum it up, flash looks for /usr/lib/libesd.so.1 (in chroot), so, symlink (in chroot) /usr/lib/libesd.so.0 to /usr/lib/libesd.so.1 and now I have sound. FWIW, I do have esound installed on chroot, but I'm not sure if its needed and I did modprobe snd-ioctl32 per a comment earlier in this thread...also not sure if that is needed.

Hope that helps anyone wanting sound with flash+chroot+esd

I had the same problem, easy to fix. Just add this bit which is missing from the instructions:

Step 4
$ sudo gedit /etc/fstab
Add the following lines:
<snip />
$ sudo mount -a
$ sudo gedit /usr/local/bin/do_dchroot

Thanks, updated!

This worked for me as well, thanks!

When I get to step 5 and enter dchroot -d, it gives me the folowing message:

diego@jarkorpc:~$ dchroot
dchroot: Invalid input line /etc/dchroot.conf:12
dchroot: Error reading config file '/etc/dchroot.conf'.

Any ideas?

Thanks. Just one thing though, is there a way to install official Debian unstable in my chroot directory?

I would just prefer this as there are a much wider range of applications for Debian unstable, they are updated more frequently and I can use debian unstable unofficial repositories without worrying that later down the line I am going to run into some kind of dependency conflict or other. (Running a mixed environment from different repositories is never a good idea. For those who have no discovered this yet, sooner or later you will end up running into unresolvable dependancy issues).

I assume it is just a case of changing the address in the intitial instructions? But what address should I use?

Thank you Crad for this how to, it worked well ! Also thank you mthaddon for your note about libxmu6.

Great work !

Very interesting... I have been trying to get Mplayer installed through synaptic, but no luck; there is still this pbm of dependencies. Would you be kind enough to tell me how you got it working?

Cheers,

I use mplayer in the chroot, but vlc works just fine in 64 bit mode. I've only run divx stuff through it (as I just got the sound working). I installed it via synaptic.

I use mplayer in the chroot

I'll have a go myself...


EDIT:

No luck... How did you get it to work?
Thx.
