Alien Bob has an article in his wiki about compat32. And he has updated the
compat32-tools package since Slackware64-13.0 was released. If you want
to run a multilib system you should stick with his advice.
There is a Nvidia driver for 64-bit. IMO you can just use that binary driver and
reinstall it whenever you have a new kernel or change in X.Org that would
require it. That is what I will do ... not everyone does the same.
IMO the question to ask is, "Why does glore2002 need a multilib Slackware64?"
If the answer is for wine and skype alone, then you'll probably not have too
many other questions along the line.
If you install compat32 packages, there are things you must blacklist if you
use a package manager such as slackpkg. Since it is the one included in Slackware,
I personally would prefer it over other third-party package managers. While running
Alien Bob's compat32 packages on this box during the Slackware64 -current cycle,
these are the packages I blacklisted:
mingdao@silas64:~$ egrep -v "(^#|^ *$)" /etc/slackpkg/blacklist
The mutt, msmtp, maildrop, irssi, and MPlayer packages are ones that I built
which are also included in Slackware. I exclude the kernel packages primarily
because I run custom kernels. The ones starting at gcc are the compat32
packages that should not be upgraded with the normal 64-bit packages.
On my computers I use official Slackware packages if available, then Alien Bob's
packages if he has them, and if not, I build them myself. No other packages...
If you are going to keep a Slackware64-13.0 stable system, and not run -current
when it's new cycle begins, you should only be upgrading the /patches directory.
Those will be easy enough to follow, and you can ask questions here about them.
And IMO you should keep your system stable, and not run -current, until you learn
more about Slackware and Linux. Otherwise, you're going to have some problems
and maybe break your system. Still, it's your choice.
