Hi all, Couple of questions about how CRAN is building packages for OSX under R 3.4.X El Cap+, prompted by our package (OpenMx) failing CRAN builds (despite building fine locally).
Q1: Is it the case that there’s no equivalent of the win.build system for package creators to test their packages against before submission? We thought https://builder.r-hub.io would be ideal for this but apparently r.hub and the CRAN build are differenent? It would seem ideal to set-up r-hub identically to the CRAN check machine… Is that possible? Q2: Can someone (Simon?) clarify here what the CRAN mac build system is? Specifically: 1. For Clang one uses clang-4.0.0-darwin15.6-Release.tar.gz<http://r.research.att.com/libs/clang-4.0.0-darwin15.6-Release.tar.gz> located at here http://r.research.att.com/libs 2. For Fortran one uses OS X El Capitan (10.11): download gfortran 6.1<http://coudert.name/software/gfortran-6.1-ElCapitan.dmg> from https://gcc.gnu.org/wiki/GFortranBinaries#MacOS (even if one if running 10.12 or 10.13, right?) 3. Make file. Is this the make file being used for CRAN check? ~/.R/Makevars CC=/usr/local/clang4/bin/clang CXX=/usr/local/clang4/bin/clang++ LDFLAGS=-L/usr/local/clang4/lib Many thanks if it is possible to clarify building packages to mirror CRAN check under 3.4.X PS: It would be great to have an Apple installer package for Clang… Perhaps getting installer packages for the build environment would be a good project for https://builder.r-hub.io ? (they are seeking <$10k projects with wide benefit, and I would have thought that keeping up an apple pkg for building R would fit that bill perfectly!!
