My kingdom for Zig to have an official mechanism to emit the Linux library stubs.

Zig’s ability to crosscompile and target arbitrary versions of glibc is PURE MAGIC. I leverage this magic in an unrelated C++ build system. But I have to hack around to get those library stubs from Zig. Would love it to be an official output.

Interesting. So here's my pretty hacky take on it.

https://github.com/forrestthewoods/anubis/blob/983d8a1b9ea5e...

It invokes zig on a dummy C or CPP file. Then it scrapes the output looking for specific files.

C: crt1.o, libm.so, libpthread.so, libc.so, libdl.so, librt.so, libld.so, libutil.so, libresolv.so, libc_nonshared.a, libcompiler_rt.a

C++: crt1.o, libc++abi.a, libc++.a, libunwind.a, libm.so, libpthread.so, libc.so, libdl.so, librt.so, libld.so, libutil.so, libresolv.so, libc_nonshared.a, libcompiler_rt.a

Zig is also a god send in that it has all the generated glibc header bullshit for Linux.

I've got a system that is able to cross-compile ffmpeg for Linux from Windows. Which is a shockingly painful and rare capability. Linux userspace design is so so so so so bad. So embarrassingly bad.

Andrew Kelley is a damn saint for the mountains he moved for Zig. https://andrewkelley.me/post/zig-cc-powerful-drop-in-replace...

Now I just wish some of this capability was exposed in a slightly more formal capacity so that it could be leveraged by the broader community :)
