Cross-compiling CGO projects has long been a challenge for Go developers. While CGO enables access to the vast ecosystem of C and C++ libraries, it introduces complexities like dependency management, slow builds, and the pitfalls of dynamic linking with glibc or musl. In this talk, we’ll explore how Zig—a modern systems programming language—can simplify cross-compilation workflows for CGO projects, enabling faster, cleaner, and more portable builds.
