[SOLVED] Slackware 14, emacs won't launch, how to install missing library?

Tachtory · 01-22-2014, 12:57 AM

It appears I'm missing a shared library for Emacs. I'm trying to launch in terminal mode. When I try to launch I get this error:

Code:

$ emacs -nw
emacs: error while loading shared libraries: libMagickWand-6.Q16.so.1: cannot open shared object file: No such file or directory

I installed the X Windows package, but did not install the X Windows Apps package. I am coming from debian distros (Mint) so usually I go to the package manager for installing missing software.

How should I proceed with Slackware, to find and install missing or new software or libraries?

If you are new to Slackware it is strongly recommended to make a full install (even long-time Slackware users usually do that).
Assuming that you have configured the slackpkg package manager correctly you would first find out which package contains that library:

Code:

>>>slackpkg file-search libMagickWand
DONE

The list below shows the packages that contains "libMagickWand" file.

[ Status           ] [ Repository               ] [ Package                                  ]
   installed                                        imagemagick-6.8.6_10-x86_64-1             

You can search specific packages using "slackpkg search package".

Your output will look different, since I use the slackpkg+ plugin, but it will nonetheless report that the package you need is the imagemagick package. So just install that:

Code:

slackpkg install imagemagick

But again, it is strongly recommended that you make a standard full installation.

Slackware is offered as an all-in-one distribution, it doesn't have tools that manage dependencies resolution, that is left to the system administrator (you).

So you should opt to switch to a full installation (the only one supported), it's easy to do it with slackpkg:

- set a mirror in /etc/slackpkg/mirrors (the one corresponding to your version, 32 or 64bit)

- give the command

Code:

slackpkg update

- then, if you're on 32bit slackware

Code:

slackpkg install slackware

if you are instead on 64bit slackware

Code:

slackpkg install slackware64

Okay, thank you for the quick reply.

Just curious, do the 'current' packages just point to 14.1 right now, or are they newer?

TobiSGD · 01-22-2014, 02:32 AM

-current is the development version of Slackware.

lems · 01-22-2014, 06:19 AM

From looking at the changelog, there were mostly security fixes in -current since 14.1 was released. Calligra was updated to 2.7.5, cairo rebuilt without specific options. and so on.

edit: Oh, and firefox was updated to the latest version (not ESR).

The emacs package installs two versions of the emacs binary: emacs-24.3-with-x11 and emacs-24.3-no-x11. And it makes a symbolic link, so that command emacs starts emacs-24.3-with-x11 as default.

You could have fixed it by using the no-x11 version, instead. As root:

Code:

ln -sf emacs-24.3-no-x11 /usr/bin/emacs

(Or 24.2 in Slackware 14.0).

Tachtory · 01-22-2014, 07:59 AM

That sounds good!

So if I'm really serious about learning emacs I could add this to my bashrc?

Code:

alias vim="emacs-24.3-no-x11"

And don't forget to put

Code:

(setq viper-mode t)
(require 'viper)

into your ~/.emacs.

Actually it's ~/.emacs.d/init.el these days.

Thanks, I did not know that. I tried emacs a few times and did not want to insult anyone. Both are powerful editors, in my opinion, it's just that I'm used to vi (I use nvi most of the time).

No sweat. It used to be ~/.emacs and that actually still works. But someday, it won't.

The fastest guy on the keyboard that I ever watched used emacs with vi keybindings. I always felt as if I should have a fire extinguisher near when I watched him type. It was mind-boggling.
