It has been a long time since I've attempted to support my software on AIX. However, my old notes mention OBJECT_MODE and COMPILE_BITS as environment variables which influence the IBM toolchain. IIRC, their use could/should eliminate the need for `-q64` and `-X 64` arguments in the 64-bit cases listed by Bruno.
See, for instance, https://www.ibm.com/docs/en/xl-fortran-aix/16.1.0?topic=environment-default-bit-mode -Paul On Mon, Oct 28, 2024 at 3:12 PM Bruno Haible via cfarm-users < cfarm-users@lists.tetaneutral.net> wrote: > Hi, > > > We've been poking around, getting to grips with how all this stuff > > works, doing some test builds of easy stuff on things that aren't linux, > > as "that's not Linux" is very much our focus.
