[R-SIG-Mac] Please test R 4.0.0 pre-releases!

Wed Apr 1 22:29:37 CEST 2020

Patrick,

firstly, please don't post such things - they are often wrong (as are parts of what you included it this e-mail) and it's impossible for us to track all blogs that have incorrect advice. Unfortunately, a lot of the issues we see out there are due to people finding bad advice and using it. Ideally, it should be sufficient to point to the official R documentation since that is the canonical source. If you post a blog, it should point to the official documentation. If that documentation is missing or not covering a need, please post here so we can fix it. It is more important that the official source is complete and much better for the community than to have random tidbits that may or may not be correct floating around.

As for the script, please do not use R tar balls - first, you're picking the wrong one (there is no R-devel for el-capitan. R 4.0.0 pre-releases are in R-4-0-branch and they are built for high sierra). Second, the tar ball doesn't have the entitlements enabled so it doesn't match the release. Please use the signed R package. This may change, but with the complications of the Apple notarization process that's what it is today.

Then there is the question of the SDK. What are you trying to setup here? What you posted here has nothing to do with the CRAN setup. You don't need 10.13 SDK to compile igraph, it compiles just fine using stock command line tools on High Sierra which is what we use on CRAN. You can, of course, pick any SDK you like, but please don't tell people that's what they should do. One of the most annoying issues is that people are recommending messing with Makevars which is incredibly fragile and will cause things to break left and right with any update. It's ok to do that for a very special purpose, but no regular user should have Makevars in their home.

So if you really want to serve the community, please suggest improvements to the official documentation and post them here. If you have special needs, ask about them here.

Thanks,
Simon

Bioconductor packages depend on thousands of CRAN packages and one thing that makes it hard for us and for our users to build/check Bioconductor packages at the moment is the absence of Mac binary packages for R 4.0.0 on CRAN. Do you have an estimate of when they will become available?

However, the build fulfils Apple's conditions and is known to pass notarization (in fact the the package available for download today is actually notarized) so it should be a good test for the release which will be notarized and should work on Catalina.
>>>> For those that want to replicate our setup - technical details: we are now building with macOS 10.13 (High Sierra) as target (i.e. the oldest supported system), regular Apple Xcode/command line tools and GNU Fortran 8.2. R builds are running on macOS 10.15 (Catalina) with Xcode 11.4 using macOS 10.13 target. Packages are built on macOS 10.13 VMs with just Apple command line tools (this should make it easy to replicate the setup using Travis, for example).
