OPN2BankEditor

I'm trying to build the package on the AUR (package opn2bankeditor-git), and I've been having this error:

Any clue on what this could be? I believe it's versioning related but I'm not sure what version of what program I should switch to.

This module needs you the extra library being installed to make graphs.

By extra library do you mean Qwt? If that's the case, I have it installed (qwt 6.2.0-1).

Anyway, looking at error, I see, there is some incompatibility with Qt 6-based Qwt... Needs some fixes on here... :thinking:

Any progress?

Good reminder, I'll try to check out this today. Recently I worked on Qt6 support at some place, and I could try it here too.

One year later, any progress?

I'll try to take a look. Mostly this module was maintained by @jpcima, however, he doesn't appear for a while. So, I'll try to debug this by myself soon.
