Installing lightweight 32-bit chroot, pacman problem

So I've decided NOT to install the i686 version of Arch over my current 64-bit installation. Instead, I am going to install a 32-bit chroot. I'm using this guide: http://wiki.archlinux.org/index.php/Ins … _in_Arch64 and everything has gone error-free until I have to sync the pacman32. I can try just "pacman32 -Sy", but it says I need to be root to perform that command. Pacman32 -h works as well, but when I go into "sudo pacman32 -h", it says "command not found"... Can anyone help me? I'm running KDE (if it matters), and I've added the correct line to my ~/.bashrc AS WELL as root's ~/.bashrc... and so far nothing has worked. I've even killed the terminal application, and rebooted, with no luck Any help?

Re: Installing lightweight 32-bit chroot, pacman problem

In Konsole type the command :

su -

then the root password and at the # prompt of root :

pacman32 -Sy
...

To use 'sudo' you have to declare what commands are permitted to a user in the sudoers file, and I am not sure if the bash aliases are recognized in that file.
It seems easier to just use the 'su' command instead.

Oh ok, I didn't know that. I thought that all I had to do was add the alias in the bashrc file. I'll try it out and let you know the results! Thanks.

EDIT

I tried the commands you posted above, but I still got

[mike@mike-desktop ~]$ su -
Password:
[root@mike-desktop ~]# pacman32 -Sy
-bash: pacman32: command not found

Re: Installing lightweight 32-bit chroot, pacman problem

So the pacman32 alias was not created for root.
Check that out.

When bash is invoked as a login shell (which is the meaning of the '-' option of su) it reads ~/.bash_profile when logging in.
So do you have that line in it :

. $HOME/.bashrc

to source the .bashrc file, where I presume you created the alias for pacman32 ?

Check also that you have that line :

Architecture = i686

in the pacman.conf of the chroot installation.

For future issues take time to study documentations and to search in the forums, to try to find the answers yourself.
And if you don't find, ask for help, showing what you tried and where you are stumped.
But, especially with Arch Linux, do not expect always hand holding, it's better to try to learn by yourself first. Isn't it?

Re: Installing lightweight 32-bit chroot, pacman problem

I had read documentation on installing the chroot environment, but the document never stated anything about having to edit ~/.bash_profile too... Anyway, thanks for your help. I'm just trying to learn more about Linux since I'm most likely going to go into an information systems major in college in half a year.

I tried to use what you had posted above, but still no luck. My files were already set up like that. Could it be a permissions issue maybe?

How could I know without infos on your installation ?

Did you check if the pacman32 alias exists when you are logged in as root after the 'su -' command ?

Post the output of these commands just after you logged in as root :

pwd
alias
ls -la $HOME
cat $HOME/.bashrc
cat $HOME/.bash_profile
ls -la /opt/arch32
...

Without data I cannot guess what the problem is with your installation.

Re: Installing lightweight 32-bit chroot, pacman problem

From my previous post :

Post the output of these commands just after you logged in as root

ie after the 'su -' command.

From the output of 'pwd' and the $ of the prompt, I think you posted the results you get as a user not as root.

So your answer cannot be used to try to understand why the pacman32 alias doesn't work as root.

Ah, I'm so sorry about that. I need to read more carefully. Here is the output after logging in as root:

Re: Installing lightweight 32-bit chroot, pacman problem

So you now have your answer to :

[mike@mike-desktop ~]$ su -
Password:
[root@mike-desktop ~]# pacman32 -Sy
-bash: pacman32: command not found

I will let you find yourself what to do now.

Post again to tell the result, after you found the solution.

Re: Installing lightweight 32-bit chroot, pacman problem

I'm pretty sure it's safe to assume it's something dealing with the

[root@mike-desktop ~]# cat $HOME/.bash_profile
cat: /root/.bash_profile: No such file or directory

So I'm going to copy the user version of .bash_profile and put it into root's... that should work?

I did what I said above, and success! Pacman32 is now recognized as a command

Thank you so much for your help berbae, I appreciate it
