R SIG Debian - Jun 2025 - arm64 r-base backports on CRAN

Hey Jeroen,

I was recently considering to do this, but did not get around to buy hardware or
look for hosting on that architecture.

I just invested in a nice amd64 system, but just for building for CRAN I wont
need too many arm64 cyles.

Any recommendations on where to look?

Cheers,

Johannes

GitHub actions has free arm64 and x86_64 runners. If you have the
build scripts somewhere, we can try to run them on there. I think this
is also where Dirk builds the arm64 ubuntu binary R packages.
