Ideally, we shouldn't need 'config.guess' at all. Normally, it is only used if the GNU triplet is not explicitly passed to ./configure. A few years ago, I fixed most instances of this problem by unconditionally passing --build=<triplet> to ./configure in the default 'configure' phase of gnu-build-system. https://git.savannah.gnu.org/cgit/guix.git/commit/?id=3c7d023d6458669c6bfa23bc85e098c91f699892 However, our OCaml package has a custom 'configure' phase that does not pass --build. I'm not sure if that's because OCaml's configure phase doesn't support --build, or if it was omitted because it's not typically needed on x86_64. * * * Anyway, more generally, I hope that we will not get in the habit of simply removing systems from 'supported-systems' when builds fail on those systems, without investigating and concluding that it would be prohibitively difficult to support the software on that system. To my mind, it's *good* to see failed builds on other architectures, to be reminded of bugs on non-x86_64 systems that should be fixed. When we remove systems from 'supported-systems' without good reason, this is somewhat analogous to deleting unfixed bug reports. What do you think? Mark
