Drop it like it's hot.

No matter how end-of-life or obscure $thing is, someone desperately needs it, IME.

can you get a better compiler back ported?

Compiler isn't a big deal. libgcc, libstdc++ etc suddenly become a nightmare

can those be linked statically? Or does that bugger up partially native assemblies?

I'd prefer to avoid writing more build logic for a single distro-arch combination, it's hard enough keeping on top of the configurations I have.

Fair. So that implies libgcc, libstdc++ etc backports if you want 14.04 to be useful.

yeah, which is a big area of responsibiliy to take on a user's system

True, though if it's the only choice for getting it running, then that's what you have to go for. four years ago is quite early in arm64 land, I'm surprised that anyone would still be running that :(

I guess issue isn't Ubuntu users, it's vendor-ubuntu-deriv users. Linux 4 Tegra etc.
