Running an old qt4 app called oom

[alextone]

I have an old qt4 app called oomidi, which is a DAW, and in which the midi workflow is better than anything else i've used in Linux, imho.

I can run it on a dual boot earlier version of Ubuntu (22.04) as that version of ubuntu allows me to add a launchpad ppa which specifically provides qt4 for those apps which require it.

My question is, can I do this (safely, or at all) for my main install of AVL-MXDE 21.3? I'd rather have just one install (one distro to rule them all) and do everything there.

I know this app is old, but it still works in the right environment, and as i wrote, the midi workflow is great for my use. If i can get it built and running in AVL-MXDE, I'd be happy.

I've looked at trying to build it as an appimage, but it may be beyond me.

I don't have the skills to upgrade it to qt5, or qt6, or i'd have done it already.

Hi Alex,

I remember oomidi well, too bad it went off the rails..

Ubuntu PPA's are always a roll of the dice and often there will either be immediate conflicts or future upgrade breakages..

The problem is that Debian Bullseye, the base of MX-21 and MXDE-EFL 21 removed QT4 from the official Debian repositories and effectively cut off all QT4 apps at the knees... The next AVL-MXE will be even further away, QT4 ain't coming back... I'm tempted to go off on a rant but this is a real problem with Linux that to a large extent doesn't occur on Windows (sure there are always edge-cases)... I also lost a few great QT4 Audio programs I used for a long time when this happened so I feel your pain..

Unless you want to read up on compiling QT4 from scratch on a newer Debian system or want to port Oomidi to QT6 I think you are in for a colossal and very frustrating waste of your time.. This is something I neither have the time or expertise to tackle unfortunately..

Yep, I hear you. I've spent the day looking at qt4 to qt5 upgrade posts, and the complexities of building appimages. Both out of my league at the moment.
