Aro is a modern C compiler written in Zig that aims for fast compilation, low memory usage, and high-quality diagnostics, with support for C standards from C89 through C23 plus common GNU and Clang extensions. It works as a standalone compiler driver and as an embeddable Zig module, powering Zig's translate-c C frontend, while its native code generation backend is still under construction.
Use cases
- compile C code
- parse C source files
- preprocess C headers and sources
- translate C headers to Zig
- check that C code conforms to C23 or earlier standards
- get clearer error messages when compiling C
- embed a C compiler frontend in a Zig-based tool
- replace gcc or clang for faster C compilation
When to choose
- You need a fast, low-memory C frontend with good diagnostics for parsing, preprocessing, or semantic analysis
- You are building Zig tooling that must consume C code, such as translation or bindings generation
- You need up-to-date C23 standards support along with GNU and Clang extensions
- You want to integrate C compilation as a library inside your own build or analysis tools
When to avoid
- You need a production-ready backend that emits optimized machine code for arbitrary targets today, since codegen is still under construction
- You need a drop-in replacement for GCC or Clang in existing production build pipelines
- You need C++ support - Aro only handles C
- You rely on the full warning sets of older standards like C11 and C17, which are not yet complete
