Linker? I hardly know her
Zig ELF Linker Improvements Devlog
Zig fans are losing it as builds go from coffee break to blink-and-done
TLDR: Zig’s new build system can now rebuild some projects almost instantly on Linux, a huge quality-of-life upgrade for developers. Fans are calling it the long-promised breakthrough, while skeptics are already stirring debate about rival projects, Windows support, and whether the speed boost matters outside development.
A glorified behind-the-scenes tool update somehow turned into a full-on comment-section event. The big news from the Zig devlog is simple in normal-person terms: the programming language’s new build system can now rebuild projects crazy fast on Linux, even when they use outside code libraries. We’re talking a jump from 36 seconds to a few hundred milliseconds in the demo logs — basically from “go make tea” to “did it already finish?” And yes, the community absolutely noticed.
The loudest reaction was pure vindication. One fan said this was “the promise that blew my mind” years ago, and others piled on with the same energy: this is the dream, this is why they cared about Zig in the first place, this is the moment it starts feeling real. Then came the giant hot take: if this speed boost expands to more systems, Zig could become “THE C replacement” — which is the kind of spicy prophecy guaranteed to start fights on any programming forum.
Of course, no online tech celebration is complete without a little drama. One commenter immediately asked whether this sudden push was connected to the Bun drama, tossing in a delicious whiff of rivalry gossip. Others were more practical, asking the very unglamorous but very real question: what about Windows? And one party-pooper brought release-build concerns, wondering if these turbo-fast rebuilds are only for development and not the final polished app. So yes, the vibes are ecstatic — but with a side of platform anxiety, competitive speculation, and classic nerd caveats.
Key Points
- •Zig’s new ELF linker, introduced in 0.16.0 and still disabled by default, has progressed beyond its earlier Zig-only linking limitations.
- •The linker can now build the self-hosted Zig compiler with LLVM and LLD libraries enabled.
- •Fast incremental rebuilds are now supported on x86_64 Linux even when linking external libraries and C sources.
- •Example build logs in the article show the Zig compiler rebuilding incrementally in roughly a few hundred milliseconds after the initial build.
- •The main missing feature identified is DWARF debug information generation for Zig code, which the author says is the next priority.
