Recommended way of installing packages in Slackware Current

Hello all,

I have installed and used Slackware 13.37 for many years in the past. Now, I want to try the Current branch of Slackware.

However, I have quickly come to notice that the Slackbuild repository is not configured for Current(makes sense).

I was trying to install Mnemosyne which build as per queue (sbopkg pointing to Slackware 14.2) upto but not further -

1. Qt5
2. Qt5-webkit
3. python3-sip
4. python3-Pyqt5
5. Mnemosyne

From this endeavor, I quickly gathered that obviously there will be incompatabilities(but not all) with the stable branch. Also, I consider this a way of learning so for the question as posed above -

1. What is the correct method to go about for the above sequence in the Current Branch (if at all possible)?

2. What are the general guidelines when dealing with installing packages in the Current branch as I have never felt any need to go outside of Slackbuilds and the system defaults itself?

Regards,

Hello,

You will get some answers in this post.

When in need of a 3rd party package I always check AlienBOB's repo first. In your case, this will get you -current packages of Qt5 and Qt5-webkit. Next step is slackbuilds.org - in my experience most Sbo scripts works fine in -current, even if there is no guarantee. In the very few cases were a Sbo script gives an error, I check Ponce's repo for tweaked buildscripts.

Thank folks for guiding. I have had some positive success in Slackware-Current (New to Current). I am having few difficulties in understanding the output of 'Mnemosyne - flashcard program' that I wanna understand.

I have installed Qt5 and Qt5-webkit from Alienbob's collections and python3-opengl from Slackbuilds. Here are my doubts in order -

1. I think sbopkg doesn't recognize Qt5 5-webkit as installed I presume - as it shows them still as 'New'?

2. As clear from the attachment screenshot of Mnemosyne queue in sbopkg, the 'python3-sip' package got build from SlackBuilds, did it take into account Qt5 packages as above?

3. Now, for the output(screenshot attached) of Mnemosyne (it built but didn't ran and threw few error outputs) that I ran from the terminal- So, I need guidance wrt this output

Code:

bash-5.0$ mnemosyne

Warning: Could not import OpenGL. Might cause a black screen on some Linux distributions. Try installing python3-opengl in that case.

Nor sure, but I wonder if you have conflicting sip versions installed. sip-4.19.18 is part of -current. If you built and installed python3-sip using the SBo script, this script builds sip-4.19.6 (if you downloaded the source file indicated on the SBo site). If so, you culd try uninstall the SBo package and, to be on the safe side, reinstall sip-4.19.18 and see if that helps.

if OP installed python3-sip then he's pointing at the wrong repository: there's no python3-sip in the unofficial repository for current.

also if OP is mixing package versions between this repository and others he's in for a lot of pain: for example, the scripts here have been tested with a specific qt5 version so if you install a more recent one (5.13.x instead of 5.9.x) the things that use it as a dependency most probably won't work.

Speaking from personal expirience, I think ponce is right, there probably is a mixing of versions/repos that need to be fixed.

I solved it in this way:
removed ALL sbo-installed packages
removed ALL external packages (sbotools, sbopkg, etc.. keeping slackpkg-plus)
removed ALL alienbob-based packages

keeped all multilib packages installed through slackpkg (they are usually harmless)

then I installed sbotools (they are my choosed sbo manager, mixing sbotools and sbopkg was definitely wrong) and changed SLACKWARE_VERSION= to current (remember to chang jobs count too, or the next step will take forever)
update/create the local repo

then using ONLY sbo, point to the package that you want (in this case Mnemosyne), sbotools actually checks automatically for dependencies, sbopkg doesn't so you'll have to do this by hand
to check if you are using the correct (unofficial-unsupported) repo, there are several MISSING packages that are reported in the requirements. That's CORRECT, they are in the base Slackware-current installation. If you find all packages, then you are in the wrong repo!

finally compile everything (yes, INCLUDING THE WHOLE QT5!) that's because qt5 from sbo and qt5 from alien are different versions, for instance. alienbob has a NEWER version that doesn't work with some programs present in sbo-current.

then blacklist sbo-compiled packages in the slackpkg-plus conf:
/etc/slackpkg/blacklist

Code:

[0-9]+_SBo

that's necessary to avoid involuntary upgrading of the packages.

it should work then
