Hi Johannes,

I really need to get proof-reading emails before sending... ) On 24 June 2025 at 20:02, Jeroen Ooms wrote: | On Tue, Jun 24, 2025 at 7:55 PM Johannes Ranke <johannes.ra...@jrwb.de> wrote: | > | > 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? | | 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. Yes, I was about to suggest that too but Jeroen beat me to it. I looked around, and noticed Hetzner has relatively inexpensive machines ... but at the end of the day it is still your money out of your pocket. I started to poke at arm64 when the (free) runner became available for ubuntu-24.04 (and they since added ubuntu-22.04 too). I actually execute the build-step in a (custom) Docker container (with added r2u resources) so you should be able to use the Ubuntu runner to start a Debian container ... and after that it is like running locally. Only umpteen times slower for debugging cycles <wink>. I also switched to building the BioC binaries for amd64 there. My (fairly ad-hoc) repo is https://github.com/eddelbuettel/r2u-arm64-builder and the action file is https://github.com/eddelbuettel/r2u-arm64-builder/blob/main/.github/workflows/arm64.yaml I respect a remote invocation reflecting the packages to build in each run, that will be easier for you as you know what to build. Ping me if you have question. Direct DM may be best, you could hop into the (open) r-contributors slack at r-contributors.slack.com Cheers, Dirk -- dirk.eddelbuettel.com | @eddelbuettel | e...@debian.org _______________________________________________ R-SIG-Debian mailing list R-SIG-Debian@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-debian
