On Windows I have a package that builds just fine with any recent version of Rtools. But on win-builder it fails because the version of GNU make on that machine does not support if-else syntax. Support for this syntax was added in GNU make 3.81, which was released in 2006. The version of Rtools on my computer comes with GNU Make 4.2.1.
I resubmitted the package to win-builder with `make --version` and found that it is using version 3.79.1. I'm curious -- why does it use such an old version of make, and one that does not come with Rtools? I've tried to follow the documentation at https://cran.r-project.org/doc/manuals/R-admin.html#The-Windows-toolset to get a build environment as close as possible to what is prescribed. But since this environment differs from what CRAN actually uses, it makes for a long and error-prone process when submitting a package to CRAN. -Winston [[alternative HTML version deleted]] ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
