Look, it’s not that complicated. If you just build your software with gcc or whatever in a docker container with pinned versions, put the binary on your website, and call it a day, 5 minutes later someone is going to complain it doesn’t work on their 3 year old Linux Mint install. The balkanization of Linux is undeniable at this point. If you want to fix this problem without breaking anything else, you have to jump through hoops (and glibc is far from the only culprit).

You can see what the best-in-class hoop jumping looks like in a bunch of open source projects that do binary releases — it’s nontrivial. Or you can see all the machinations that Flatpak goes through to get userspace Mesa drivers etc. working on a different glibc version than the base system. On every other major OS, including other free software ones, this isn’t a problem. Like at all. Windows’ infamous MSVC versioning is even mostly a non-issue at this point, and all you had to do before was bundle the right version in your installer. I’ll take a single compiler flag over the Linux mess every day of the week.

Do you distribute a commercial product to a large Linux userbase, without refusing to support anything that isn’t Ubuntu LTS? I’m kind of doubting that, because me and everyone I know who didn’t go with a pure Electron app (which mostly solves this for you with their own build process complexity) has wasted a bunch of time on this issue. Even statically linking with musl has its futziness, and that’s literally impossible for many apps (e.g. anything that touches a GPU). The Linux ecosystem could make a few pretty minor attitude adjustments and improve things with almost no downside, but it won’t. So the year of the Linux desktop remains illusive.
