Using a chroot

[emoguitarist06]

I'm running Ubuntu 10.10 64bit and I have succesfully installed 10.10 32bit as a chroot using https://help.ubuntu.com/community/BasicChroot
I'm able to go into the chroot shell and it works perfectly

Now I need to know how to use it lol

I want to run PCSX2. I have it downloaded in my personal Downloads folder but how to I access it from a chroot? also will I have to install all the libs required for PCSX2 within the chroot itself?

I'm lost

any direction whatsoever would help!!

Howdy,

Chroot is very last century and a pain in the derrier to use. You should rather use VMware or Virtualbox.

What? Are you Sure? I understand virtualization as I run Windows 7 in VirtualBox

According to PCSX2
http://code.google.com/p/pcsx2/wiki/...64bStatusLinux
CHROOT is the best route to take which was just updated in September

I am not trying to virtualize an entire operating system and WASTE that much resources just for 1 program

https://help.ubuntu.com/community/BasicChroot states that one good use of chroot is for Running 32-bit applications on 64-bit systems

Did you bind mount your home directory (or whatever other directory) in /etc/fstab?

also will I have to install all the libs required for PCSX2 within the chroot itself?

Yes. That's the point of the chroot (to use 32-bit libs).

LOL. The 3D support/performance provided by the virtualbox driver is nowhere near what one can get with a native chroot. Chroots are not deprecated by VM's.

No but I will tonight and post my results
I did check
$ sudo editor /etc/schroot/mount-defaults
and made sure nothing was commented (#)

Yes. That's the point of the chroot (to use 32-bit libs).

So obviously I'm going to need to add the repos to be able to add the libs.

That what I thought

[emoguitarist06]

I mounted my home folder into my chroot using

sudo mount -o bind /home /var/chroot/home

it worked perfectly

Now how do I add repos? I can't

gedit /etc/apt/sources.list

because gedit isn't installed

and what repos do I need?

You need the following installed: libasound2-dev, libbz2-dev, libgl1-mesa-dev, libglew1.5-dev, libglu1-mesa-dev, libgtk2.0-dev, libjpeg-dev, libsdl1.2-dev, libsoundtouch1-dev, libsparsehash-dev, libwxbase2.8-dev, libwxgtk2.8-dev, libx11-dev, nvidia-cg-toolkit, portaudio19-dev, zlib1g-dev

I also tried

sudo add-apt-repository ppa:gregory-hainaut/pcsx2.official.ppa

but "add-apt-repository" isn't found lol

That's the official PPA noted here

UPDATE

I copied all the repos from my friends 32bit Maverick and I installed all libs BUT here is my problem

root@phillipguy-laptop:~/Downloads/pcsx2-0.9.7-r3881# ./pcsx2 
Error: Unable to initialize gtk, is DISPLAY set properly?

I have tried

export DISPLAY=:0.0

as noted here:https://help.ubuntu.com/community/BasicChroot
but still no luck

[emoguitarist06]

SOLVED

Using the knowledge here:
http://wiki.mandriva.com/en/Developm...ide_the_chroot

I installed Xephyr
which in Maverick is:

sudo apt-get install xserver-xephyr

I mounted /dev/input/ to my chroot so I can use my PS3 Sixaxis controller
in chroot shell

mkdir /dev/input

outside shell

sudo mount -o bind /dev/input /var/chroot/dev/input

Finally to run my graphical application
outside shell

Xephyr -ac -fullscreen :1

You can remove -fullscreen if you don't want fullscreen but for PCSX2 I couldn't play it without -fullscreen
inside chroot

export DISPLAY=localhost:1

and then run your program... in my case ./home/phillipguy/Downloads/pcsx2
