Anatomy of Cross-Compilation Toolchains

on YouTube ↗59m

" summary

Cross-compilation toolchains are four pieces: binutils, GCC, kernel headers, C library. Build order is binutils → host libs (GMP/MPFR/MPC) → install kernel headers → stage‑1 GCC (no libc) → build libc for the target → final GCC; sysroot holds target headers/libs and can be made relocatable or overridden with --sysroot. glibc binaries add about 1.7 MB vs uClibc/musl roughly 1.1–1.4 MB in a simple ARM toolchain, and a full toolchain build typically completes in ~15–20 minutes on a modern machine.
