libqt4-dev and libqscintilla2-dev missing in Linux Mint 20.3

After upgrading to Linux Mint 20.3 I encountered this problem:
Code: Select all
E: Package 'libqt4-dev' has no installation candidate
E: Unable to locate package libqscintilla2-dev
I need those two for installing miniAudicle (IDE for ChucK). What to do now?

Upstream Debian has removed QT4 with the release of Debian 11 Bullseye, other Debian-based projects like Ubuntu, Mint etc. will also not have it unless they specially package it themselves which is unlikely since QT5 has been around for years and has now been replaced by QT6. If you want QT4 support you will need to use an older version of Mint..
I'm guessing miniAudicle is old and unmaintained software?

That's a problem then because miniAudicle which needs those two programs is an IDE for the programming language ChucK. There is also the IDE Audicle but that is hard to work with. Now I can no longer use ChucK...

miniAudicle seems to be actively developed, or at least has fairly recent commits in its Github repo:
https://github.com/ccrma/miniAudicle/commits/main
There looks to be a pull request which would update the code to use QT5:
https://github.com/ccrma/miniAudicle/pull/44
Perhaps you could clone it, apply the patch from that PR, and have a go at building it yourself?

Thanks, in that case I better wait for a while till a new well tested version of miniAudicle is ready that runs on Linux Mint 20.3.
