Slackware update

The last time I (re)installed Slackware I documented what I did. Somehow I managed to really bork my installation and I decided to go through with a larger reinstallation once more. This is a log of some things I did differently.


Before installing the kernel it’s nice to check the GPG signature of the downloaded packages. With the kernel GPG signature we can simply do:

wget linux-XX.tar.xz
wget linux-XX.tar.sign
unxz linux.tar.xz
gpg --verify *.sign

When making oldconfig yes "" | oldconfig saves time.


I didn’t use this tool previously, but it can be used to update the official Slackware packages. Just remember to update the gpg signature as well.

slackpkg update
slackpkg update gpg

I didn’t take the plunge to slackware-current just yet, I might do it at a later time when I feel I have a lot of unused time (will I ever?), but it’s easy to update selected packages.

slackpkg upgrade git

Will only update git for example.


I did some strange things here, the one which worked was simply as root:

cpan install CPAN
cpan install DateTime

Slackbuilds with sbopkg

Slackbuilds works well but can be cumbersome. sbopkg is a great little tool which makes downloading and installing much easier.

Hakyll and xmonad

This gave me a lot of problems. At first I installed xmonad and xmonad-contrib from slackbuilds and I tried to install Hakyll from cabal, but conflicts ensued and they couldn’t really work together.

I tried to move cabal out from my home director, but didn’t find a very satisfactory solution and in the end I just gave up.

The first thing to do is to install ghc from slackbuilds. Then install the Cabal lib and cabal-install from (they are in the same lib).

Then install a newer version of ghc from their prebuilt binaries at

There I got the error that couldn’t be found. This was solved by symlinking to libncurses with ln -s /lib64/ /lib64/

Then we can install things with cabal as a regular user:

cabal install cabal-install
cabal install hscolour
cabal install missingH
cabal install hakyll
cabal install xmonad
cabal install xmonad-contrib

If you get the error:

pandoc- failed during the configure step. The exception was:
user error ('/usr/bin/ghc' exited with an error:
/usr/lib64/ghc-7.8.4/unix- In function
execvpe.c:(.text+0x300): multiple definition of `pPrPr_disableITimers'
first defined here

Try rerunning cabal install cabal-install and then try to install hakyll again. This shouldn’t happen with an updated ghc though.

From source

  1. fish shell
  2. neovim (xclip from slackbuilds)
  3. rust (nightly build)
  4. dzen2 (edit and use Xinerama, XPM and XFT)

If you get

rustc: error while loading shared libraries:
cannot open shared object file: No such file or directory

it’s because rust installed it in /usr/local/lib which is not in the default search path. Can add /usr/local/lib to LD_LIBRARY_PATH or issue ldconfig /usr/local/lib for instant gratification.


This can be done with everything as regular user.

git clone ~/.rakudobrew

Add ~/.rakudobrew/bin to path. Then we can install package manager panda and VM moar:

rakudobrew build moar
rakudobrew build-panda

Then with panda we can install modules:

panda install Task::Star


Install from slackbuilds. Check readme! After installation, to allow for no password for postgres (useful for pure local) alter /var/lib/pgsql/9.4/data/pg_hba.conf

and add the line

local   all     postgres    trust

before all other configurations.


This time I’m having trouble with getting sound working in Skype. To be continued… Maybe.
