The author covers what Crosstool-NG is, how target triples work, and the two main hurdles encountered: using an outdated distro package versus building from source, and configuring the unusual nan2008 floating-point convention on a mips32r2 target. The solution required adding -mnan=2008 to CFLAGS/LDFLAGS, --with-nan2008 to the C compiler options, and the same flag in the C library screen. The resulting toolchain successfully compiled busybox and a small text editor (kilo) for the printer, producing slightly smaller binaries than the Zig approach and without needing to patch ELF headers. ## Full article daily.dev links to this article rather than hosting it.
