The case that bit me yesterday was a Bioconductor package Rigraphlib, see https://bioconductor.org/packages/release/bioc/src/contrib/Rigraphlib_1.0.0.tar.gz This package builds a static library entirely from a configure script. Because there is no 'src' dir, we assumed the package to be all-arch, and get linking errors when trying to use it on another arch then it was built for. Arguably this is indeed bad package design, but that is hard to protect against. > I wouldn't think that should happen as configure is supposed to only guide > the compilation in src - if there is no src no binaries are expected as the > package did not provide any native sources hence there should be no binary > content. This looks like something that could be added to R CMD check? In that case maybe R should warn if it runs a package configure script but there is no "src"? And check if NeedsCompilation: yes is set? One way or another, what matters is that when R runs configure or make during install, the value in the "Built" field in the binary package should contain the platform value. This is also important when distros ship R packages in deb or rpm format, to prevent packages that have compiled code from getting "Architecture: all" and be installed on the wrong platforms. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
