Kairo Compiler 0.1.1-beta-rc.20260724

Stage 0 release build. See full changelog below.

Changes

All changes are in lib-helix, Stage 0's corelib. The compiler itself is unchanged.

Why "lib-helix" and not "lib-kairo"?

The name is a per-rebrand holdover encoded throughout Stage 0. Renaming it would mean churning a frozen compiler for a cosmetic change, so it stays as-is.

• Fixed an aligned-new / misaligned-delete mismatch. delete is now correctly aligned.
• Removed <minmax> from the C++ standard headers pulled in by core-lib, avoiding the min/max macro pollution.
• Updated licensing information.

System requirements

• macOS: 13.3 (Ventura) or newer
• Linux: glibc 2.35 or newer (Ubuntu 22.04+, Debian 12+, RHEL 9+, Fedora 37+)
• Windows: Windows 10 or newer (no VC++ Redistributable required runtime is statically linked)

To compile Kairo code, Stage 0 invokes Clang 18+ with libc++, which must be on your PATH. libstdc++ and GCC are not supported.

• Linux / macOS: install Clang and libc++ - e.g. apt install clang libc++-dev libc++abi-dev,
  or brew install llvm
• Windows: install Clang via the Visual Studio "C++ Clang tools" component, or a standalone
  LLVM release. clang++ must be on your PATH.

Troubleshooting

macOS: "cannot verify this app is free of malware" when running a downloaded release binary.
Release binaries aren't yet notarized. Clear the quarantine flag:

xattr -dr com.apple.quarantine ./kairo
