Dear R-package-devel, My package "albatross" doesn't contain any compiled code and has been checked on both a POSIX-compatible system and on Windows, so I wasn't expecting any problems after seeing it pass CRAN "pretest" checks. Imagine my surprise when it failed a test on M1mac while reading some files that the test creates in a temporary directory:
https://www.stats.ox.ac.uk/pub/bdr/M1mac/albatross.out Admittedly, I missed a chance to provide a useful test failure message here, so I only know that the names differ from my expectations, not what the differences are. I changed the function to output the actual differences, but so far wasn't able to reproduce the failure; apparently it's not a Mac-specific problem, since the package passed the test on R-hub's "CRAN-like" Mac setup: https://artifacts.r-hub.io/albatross_0.3-0.tar.gz-6df95a00d916dc9c5ff28bdfe2a1e217/albatross.Rcheck/ I had an idea to rent some CPU time on an M1 machine (buying my own not being an option). The Web is full of ads for Scaleway offering exactly this service, but when I checked, they turned out to be out of stock. I'm probably doing something stupid with the file names that usually works but isn't guaranteed to work in all cases, but I cannot figure it out. What should I do to debug this problem? I really don't want to be bothering CRAN with small updates that only help diagnose the problem instead of fixing it. Please keep me Cc:-d in your replies if possible. -- Best, Ivan ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
