That gives me more motivation to beat Nvidia/ARM to the punch and do the upgrade myself. ~Brian
math/R: Flang is broken for the foreseeable future; switch arm64 to gfortran
Hi Ingo --
When we upgraded to llvm-10.0.0, I had to mark flang as BROKEN [0]
because upstream has not yet ported what is now called Classic Flang
to llvm-10, as most efforts have shifted to the new Flang, which has
been upstreamed into mainline LLVM. There are plans to upgrade Classic
Flang to llvm-10 but nothing as of yet has manifested, and there is no
timetable for such an upgrade.
As a result, R will no longer build on arm64, since it uses flang for
its Fortran code. The solution is, at least for now, to switch arm64
to use gfortran, which the attached diff does. I don't have an arm64
available to test, so I am hoping someone can volunteer to test this
out and make sure it builds.
OK?
~Brian

Re: math/R: Flang is broken for the foreseeable future; switch arm64 to gfortran
I've slipped this into the currently running aarch64 bulk build, it
fails with:
...
checking size of int... configure: error: in
`/usr/obj/ports/R-4.0.2/build-aarch64':
configure: error: cannot compute sizeof (int)
