Possibly, yes. > What version of the compiler is running on rhub and how is it different from > CRAN r-release-osx-x86_64 or even CRAN r-oldrel-osx-x86_64 R-hub uses the standard system compiler in Xcode. CRAN checks use their custom built clang compiler. This is usually compatible with the system compiler, except for some rare ABI issues. You can download it at https://cran.r-project.org/bin/macosx/tools/ The check flavors page at https://cran.r-project.org/web/checks/check_flavors.html might be outdated, as it still shows clang 4.0.0. I don't know, I cannot speak for CRAN. > About CRAN (Question 2): What can be a reason why a package fails on > r-release-osx-x86_64 but checked fine on r-oldrel-osx-x86_64 Hard to say. I think you only have a real chance to fix this if you can reproduce it on your machine.
