I share your concern about niche architectures. We are running ARM64 in CI now. We have no access to an easy bigendian platform to test on. I tried Travis S390 for a while, but the CI itself was very unreliable on that platform, frequent timeouts made it hard to keep in the test matrix, so I dropped it. Access to a big-endian machine with a modern build chain would be handy for occasional manual test runs, and of course debugging. "It don't work" is so nonactionable, and with the only access to alternative architectures being CI sometimes, it's hard to fix problems that do arise (see the litany of weird MIPS failures that Debian reports) P. > On Oct 15, 2020, at 12:39 PM, Roger Bivand wrote: > > OT: We've been worried by not being able to build GEOS on Solaris 10 on ix64/x64 with GEOS after 3.6 - we had had a Sparc Solaris to run checks on a big-endian system, and have continued on Intel Solaris, and because the build train is divergent, it finds lots of assumptions made in coding, and since 3.6, we haven't been able to install GEOS. With Apple Silicon coming, it would be helpful to solve the Solaris build problem to keep our check systems up to date:
