I think this is happening because the r-src crate is running the wrong R executable to determine the linker flags. The check system is running /Users/ripley/R/R-devel/bin/R, while there's also a different R (for example, /usr/local/bin/R) visible on the $PATH. The code ends up getting the linker flags from the latter when it runs "R" [1]. I think it should be possible to sidestep this issue altogether if you only enable the static library at [2] and then have R link the package shared library for you from the static library produced by Rust using the flags you're correctly setting in Makevars [3]. If you do need Rust to determine the linker flags by itself, make sure to run ${R_HOME}/bin/R, not just R [4]. Unrelated but probably important: having 'all' or $(SHLIB) depend on a target that removes the files you've built [5] is a bad idea because Make is allowed to run independent recipes in undefined order, including rm -Rf $(SHLIB) $(STATLIB) $(OBJECTS) while $(STATLIB) is being built [6]. Note how 'rm -Rf ...' is the first command being run in [7], before any compilation happens. The files you're removing as part of the $(STATLIB) recipe should be enough; there shouldn't be any need for the 'C_clean' recipe. -- Best regards, Ivan [1] https://github.com/blas-lapack-rs/r-src/blob/966266425b1a21a1e979f767c6023e6bf00616fc/build.rs#L112 [2] https://github.com/oxfordcontrol/clarabel-r/blob/13219b94cfa018091cb3ea31c51dff2116704e0a/src/rust/Cargo.toml#L7 see also https://github.com/r-rust/hellorust/blob/master/src/myrustlib/Cargo.toml [3] https://github.com/oxfordcontrol/clarabel-r/blob/13219b94cfa018091cb3ea31c51dff2116704e0a/src/Makevars.in#L12 [4] https://cran.r-project.org/doc/manuals/R-exts.html#Configure-and-cleanup [5] https://github.com/oxfordcontrol/clarabel-r/blob/13219b94cfa018091cb3ea31c51dff2116704e0a/src/Makevars.in#L17 [6] https://cran.r-project.org/doc/manuals/R-exts.html#Using-Makevars [7] https://www.stats.ox.ac.uk/pub/bdr/M1mac/clarabel.log ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
