[Slackbuilds-users] Problem/fix for SlackBuild for MP3Diags

[David Halliwell]

    Hello. A long-time Slackware user here, but relatively new to using 
SlackBuilds. Sending this email without subscribing to the mailing list.

    Today, I wanted to build/install the MP3Diags software 
(https://slackbuilds.org/repository/15.0/audio/MP3Diags/?search=mp3diag). 
It would not build, exiting with a message about not finding Qwidget. I 
had seen the qt4 dependency, and had downloaded, built, and installed 
qt4 using he Slackbuild, but MP3Diags would not build on my Slackware 
15.0 system (upgraded last year from 14.2). I also tried building it on 
a fairly clean Slackware 15.0 VM, but had the same error.

    Looking closely at the SlackBuild script and the errors messages on 
the terminal window, I was able to determine that the build script was 
finding and using qmake from the standard qt5 installation, not the qt4 
version. I manged to work around this by changing line 83 from 'qmake' 
to '/usr/lib64/qt4/bin/qmake', and then I also needed to change line 88 
from 'lrelease' to '/usr/lib64/qt4/bin/lrelease'. After those changes, 
MP3Diags built, installed, and ran successfully.

    I have contacted Dominik Drobek (the listed maintainer) about this. 
He is still on 14.2, and he mentioned that there is a newer version of 
MP3Diags available upstream that uses qt5, but he does not have time to 
do any updates now. He suggested that I take over - but I also do not 
have time, and do not feel I have the necessary skills to be able to 
revise the script for a new version.

    I don't know if my fix is the best way, or whether there is 
something odd about my system with leftover cruft from previous 
Slackware versions, but I thought I'd take the time to send in the 
information on the fix I have found, in case someone can make the 
changes - or has a better solution.

    Thanks for having this resource available.
