💖 CONFIG.GUESS — the config.guess manual page, bestie edition 💖

okay so you opened the manual for config.guess and honestly? iconic choice. it's a User Commands situation, so let's get into it ✨

✨ NAME ✨

config.guess — guess the build system triplet 🦋

🎀 SYNOPSIS 🎀

config.guess [OPTION]

👑 DESCRIPTION 👑

ok so the GNU build system is lowkey obsessed with the idea that there are three types of machines and you need to keep them straight, no cap:

  • the build machine — the one where the compilers actually get run 💅
  • the host machine — the one where the package you're building will actually run 🌸
  • the target machine — and this one only shows up when you're building a compiler, assembler, etc., and it's the machine that the compiler you're building will produce code for 🧚

This script will guess the type of the build machine. that's literally its whole thing, and it ate.

It outputs the configuration name of the system config.guess is run on. fr fr, that's it. 🫶

✨ OPTIONS ✨

  • -h, --help — print this help, then exit 🙈
  • -t, --time-stamp — print date of last modification, then exit ⭐
  • -v, --version — print version number, then exit 💜

🌈 ENVIRONMENT VARIABLES 🌈

so here's the tea: config.guess might need to compile and run C code, which means it needs a compiler for the build machine. that's why we have the environment variable CC_FOR_BUILD — use it to specify the compiler for the build machine 💖

If CC_FOR_BUILD is not specified, CC will be used instead. But be sure to specify CC_FOR_BUILD if CC is a cross-compiler to the host machine. like, genuinely, do not skip that part, bestie 😭

  • CC_FOR_BUILD — a native C compiler, defaults to cc 💅
  • CC — a native C compiler, CC_FOR_BUILD is preferred 👑

💀 REPORTING BUGS 💀
