alt Hacker NewsYeah, it's mind boggling how everything hard depends on glibc, even critical graphics systems.
I've become obsessed with getting rid of it, especially after I realized that contributing to GNU itself was a dead end. Freestanding Linux programming turned out to be much more fun anyway.
All libraries out there should adopt the SQLite design: programmers provide it with all the necessary functions. Instead of libraries hard depending on glibc, we get to inject the libc-ish subset it needs. Then we can use whatever we want under the hood. I'm working on porting SQLite to freestanding Linux system calls so it can run with zero dependencies. Wish I could say the same for software like mesa, I'd need a lot of help for this one...

We have a similar no dependency philosophy
SQLite already does this with its VFS layer. You hand it the OS functions it needs instead of it grabbing them, etc.
You could look at going straight to syscalls, mesa would be a rewrite nightmare
I went zero-dependency on a production CMS. Rust, no framework, no external crates beyond argon2 for password hashing. Running live on client sites. The hard part wasn't building it, it was accepting that everything you reach for is pulling glibc or similar assumptions back in through the side door. SQLite's VFS model is the right pattern. More things should work that way.
Modularizing (and versioning each part independently) libc would go a long way. There is also a need to separate the stuff needed for system integration with what is necessary for users of the C language to actually do stuff.
