Hello Charles, when looking up the FAQs at the "R" project ( https://cran.r-project.org/doc/FAQ/R-FAQ.html) I can read under "2.2 What machines does R run on?" that s390x (64-bit, big endian) is an officially supported architecture. And I can even find some 32-bit architectures there: "The current version of R will configure and build under a number of common Unix-like (e.g., https://en.wikipedia.org/wiki/Unix-like) platforms including cpu-linux-gnu for the i386, amd64/x86_64, alpha, arm, arm64, hppa, mips/mipsel, powerpc, s390x and sparc CPUs (e.g., https://buildd.debian.org/build.php?&pkg=r-base), 386-hurd-gnu, cpu-kfreebsd-gnu for i386 and amd64, i386-pc-solaris, rs6000-ibm-aix, sparc-sun-solaris, x86_64-apple-darwin, aarch64-apple-darwin, x86_64-unknown-freebsd and x86_64-unknown-openbsd."
I also searched (on a high level) through the release notes: https://cran.r-project.org/doc/manuals/r-release/NEWS.html and couldn't find a stmt indicating that either big endian is not longer supported or that 32-bit support got dropped upstream Did something recently changed that I am not aware of and/or the FAQ is not up to date anymore ? Do you have a reference for your stmt that I can look up? BR, Frank
