One Toolchain for Every Platform. In C++. Even in the Browser.

说明与用途

将 C++ 交叉编译中的主机和目标分离，将所需工件从 200 个减少到 30 个，使得可以从任何主机（包括浏览器）构建 20 个平台的应用程序，同时遵守 Windows 和 macOS 的许可限制。

问题

Building a C++ application for multiple platforms from a single machine is difficult because each target requires a separate sysroot and compiler build, leading to large build times and complex toolchains.

结果

A universal C++ toolchain that separates host and target artifacts reduces build complexity from 200 to 30 tarballs, enabling compilation for 20 targets from any host, including browsers, while respecting legal constraints on Windows and macOS SDKs.

工作流

• 1. Build the host compiler for the current machine (build).
• 2. Build the target compiler for the same architecture.
• 3. Build host compilers for all other architectures using the already built targets.
• 4. Separate host artifacts (compiler, linker, build driver, binutils, resource headers) from target artifacts (sysroot, headers, libraries).
• 5. Use the host compiler to build applications for any target, regardless of host OS.
• 6. Optionally run the compiler in a browser via Emscripten or similar.
• 7. Distribute the target tarballs only if legal licenses allow (e.g., Windows SDK restrictions).

证据

The whole concept of cross‑compilation revolves around the triplet…

If target and host are separated, it's 30 tarballs, and only 10 of them are heavy builds.

The whole thing can be done on one machine in one OS, though only if that OS is Linux.
