[SOLVED] Quick questions regarding installing multi-library packages!

Laxman_prodigy · 07-11-2012, 03:16 AM

Hi.
Needed skype and other apps to run, so thought of enabling 32 bit compatibility!!

I see the wiki as here: http://alien.slackbook.org/dokuwiki/...kware:multilib but, do I have to download every package one by one? As that's what I am doing right now! And do I have to download other files as well or just the .txz ones as that's the one we install with installpkg?

So, my question is : "How do you do it?"

What you do is follow the instructions on the page you have linked to.

First "Obtaining multilib packages" then "Enabling multilib support on Slackware64".

No.

Code:

cd ~
mkdir multilib
cd multilib
lftp -c "open http://connie.slackware.com/~alien/multilib/; mirror 13.37"

Thanks Didier!! Fired it!

Okay, so I got upto the step where it says now, "Adding 32-bit Slackware libraries". Now, since I don't have the 32 bit DVD, how would I proceed?

Do I need to download the whole DVD or I can get away with ftp programs that fetch the required libraries only? I am new at this and doing a quite a bit of reading too. So, if there is/are command/s that can get the same job done without downloading the whole sets?

A slight tweak to the lftp command and you could use it to fetch updates as well:

Code:

lftp -c "open http://connie.slackware.com/~alien/multilib/; mirror -en 13.37"

F.Y.I. As a one off download this would have worked as well (though syncing updates would be tricker):

Code:

wget -r -np -nH --cut-dirs 1 -Rindex.html* -erobots=off http://connie.slackware.com/~alien/multilib/13.37/

That question is answered in the "quick and dirty instructions":

Code:

If you are running Slackware 13.1 or newer, and downloaded the compat32-tools package for that
release, the massconvert32.sh script can use a remote webserver to download the 32-bit Slackware
packages from, instead of requiring a local Slackware mirror or a DVD. You use the ”-u” parameter to
specify the remote URL like this:

massconvert32.sh -u http://someserver.org/path/to/slackware-13.37/slackware

You don't necessarily need to convert the 32 libs, instead you can install the packages within the slackware64-compat32 subdirectory. These have been done for you.

You are reading the README, right? This had the lftp command and advice with regards to the installing the libraries in the "Enabling multilib/Fast-track" section.

Hi.

Will the first command get the 32 bit Slackware tree/libraries? Coz I am stuck at this part of the multilib guidelines "Adding 32-bit Slackware libraries".

Edit: Roger that, I am on it. Thanks.

yes

Laxman_prodigy · 07-11-2012, 05:19 AM

Okay, so as far I get it, the first two commands in the "The quick 'n' dirty instructions" is all I need to get the multilib functionality and the rest below are for things and stuff as and when needed right?

ruario · 07-11-2012, 05:23 AM

The first two commands are for those with the slackware64-compat32 subdirectory (that would be you, if ran the suggested lftp command). The other commands there for those without this directory. The instructions do say all of this.

If you also downloaded a directory called slackware64-compat32 then you are lucky, because I did the 32bit package conversion for you already!

If you can't find that subdirectory called slackware64-compat32 then you have to do the conversion yourself.

Aah, yes man! Slightly got confused with the continuous reading. So, I was saying, I have ran the first two commands after using the lftp command suggested by the some previous poster, it ran successfully and completed! Do I need to do more still? I am reading the following instructions and I am getting it quite! But, I think I got multi-lib'ed already, have I?

You should be done, for the most part. Though you may also wish to configure slackpkg if you use that for updates, i.e.

If you run Slackware 13.37 or newer, then slackpkg supports regular expressions in the blacklist file. In that case, a single line in /etc/slackpkg/blacklist will be enough to blacklist all of my packages (including multilib gcc and glibc packages and all compat32 packages):
