Re: [R-sig-Debian] R 4.0 for ARM processors
@Johannes - Thank you for your suggestion. I see the wisdom in it. I like having pre-built binaries because I'm lazy; but in this case, being lazy is causing too much work. @Patrice - Thanks for sharing the story and those links. It seems the Odroid is like the RPi 3. The newer RPi 4 has (up to) 4 GB of memory, so I hope I won't need 12 boards! (PS - It's pretty cool that someone made a midi sequencer from their Odroid. I never thought of using my RPi that way.)

I think it would be preferable to add to your /etc/apt/sources.list deb-src https://cloud.r-project.org/bin/linux/ubuntu focal-cran40/ to get access to the source packages for R 4.0.2, and then do sudo apt update sudo apt build-dep r-base and sudo apt source -b r-base to build these on your arm cluster for your architecture. Of course you will need to rebuild after R releases to keep up to date. Johannes ___ R-SIG-Debian mailing list R-SIG-Debian@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-debian
