We could also patch > our build tools but the problem would still exist for other distros. yes, Gentoo fixed this for every package in our tree like 9 years ago (we added a common function like 11 years ago that ebuilds could call manually, but we found that didn't scale). when you run a standard autoconf script, we automatically search for files named "config.sub" and "config.guess" and replace them with the up-to-date host copy. no checking or anything :). in hindsight, that seems like a bad idea, but in practice, i think we have yet to find a package that this doesn't actually work. and behold, no one has ever complained about config.sub not recognizing their mips or sparc or x86_64 or aarch64 system ever again. > If anyone knows where config.guess and config.sub are installed on > common platforms like the various Linux or BSD distributions, please let > me know those locations. I have only the paths for Debian and Gentoo. if Gentoo is the only one that uses /usr/share/gnuconfig/ and every one else picked /usr/share/misc/, then i'll just move Gentoo. don't bother listing it in your patch. even then, many of the other paths (like internal automake/libtool) will work fine on Gentoo. we picked .../gnuconfig/ as it installs more than one file and FHS generally recommends that packages w/more than one file not go into .../misc/. -mike
