> How do I get my application to my users? For historical reasons, there hasn't been a good answer to this question for a long, long time What is wrong with a binary in a tarball, like Firefox and Blender and VSCode and everyone else uses? This always seemed like a non-problem to me.
Linker errors
You just bundle all libraries except glibc in the tarball. You build against the oldest glibc you're willing to call "supported". Firefox and Blender (among many others) have been doing this for as long as I can remember, and as long as I can remember their tarballs have never failed to work for me, on any distro.
The problem seems to me to be that there's some kind of cultural imperative to attempt to dynamically link against whatever the system version of a library is, which is clearly insanity.
