Hi,

For a small ARM pocket PC (Pandora) I've installed slackware 14.2 created by Linux-SWAT on the Pandora forums.
https://pandorawiki.org/Software_projects/OS/Slackware

Reason for installing Slackware is to be able to install more recent versions of software. The Pandora is a very old device and basically EOL. I was hoping with Slackware I can install and use more recent versions of software.

One of the packages I was hoping to use is a more recent version of FBreader.
http://slackbuilds.org/repository/14.2/office/fbreader/

First issue I ran into was a QT related problem.

Solution that Linux-SWAT provided was updating the slackbuild with:

export UI_TYPE=qt4
into
export UI_TYPE=gtk

QT error was indeed fixed, but after a long time compiling it failed with a new error

Anyone a suggestion how to fix the issue?

This should have been posted in the Slackware ARM sub-forum.

OK let's also give some actual feedback. Unfortunately I can not help you with this compiliation error.

There is no 'recent' version of FBreader for Linux. The 0.99.4 release is the most recent but it stems from 2012, i.e. 9 years old and no guarantee that there will ever be a new Linux release. The user interface is Qt4 based (Gentoo wrote a patch to port this to Qt5) but the GTK+ user interface is actually unsupported according to the website, and is not even guaranteed to work.

I ditched FBreader a long time ago and switched to calibre. Calibre is an e-book management library but it also contains a very good e-book reader as well as an e-book editor. I doubt however that there's a pre-compiled version of it for ARM Linux. Compiling from source is not trivial. You could try my SlackBuild script for calibre (http://www.slackware.com/~alien/slackbuilds/calibre/), it compiles everything you need into a single package. Part of what it compiles is Qt5 so it may be too tough on your old ARM PC.

But on my Android phone, I use FBreader a lot - the Android version is actively developed and very sleek. A pity that the Linux version is not getting the same level of attention.

On the Pandora there is a few months older FBreader version available for the default OS that still works fine (from april 2012). Indeed too bad they went the commercial route, but luckily there are more alternative readers. I was also able to install coolreader on Slackware with sbopkg. Coolreader is also using QT4 so apparently not every QT4 program fails.
I will certainly give Calibre a try even if it is only to see if it works. Might indeed be too heavy though, next to an older CPU the Pandora has limited memory.
Another reader I am interested in is Foliate. Not available as slackbuild but it might work via flatpak. Flatpak is available as slackbuild.

Thanks for the help and I will post my next questions in the ARM section

Tried your Slackbuild script but it failed to dl 5.13 from https://download.qt.io/official_releases/qt/. Only 5.12 and 5.15 are available from that site. On my device QT 5.9.7 is installed.
Noticed in the script INT_QT=5.13.2 - change it to INT_QT=5.15.2? And try again?
