> Setting up a machine or build system for older glibc is not trivial .

God, I hate glibc so much. It’s an absolutely terrible design from the 80s. It can and should be trivial to target any arbitrary version of glibc. The way Linux performs linking is so bad and so much worse than Windows. (Headers + thin import lib. Linking expecting a full and complete so is stupid and bad.)

Zig solved this problem. It can trivially target any version of glibc and cross-compile. It’d be nice if the Linux community demanded this level of functionality from their toolchains. Alas. https://andrewkelley.me/post/zig-cc-powerful-drop-in-replace...
