Are you the OP behind the StackOverflow question here: https://stackoverflow.com/questions/46280628/object-files-in-r-package-too-large-rcpp If so we already tried to answer. This is NOT an issue for CRAN but merely a warning. Do yourself a quick favour and run file.info( system.file("libs", "dplyr.so", package="dplyr") )$size and you see that some well-known and widely used packages are MUCH bigger. | I read with interest this article | http://dirk.eddelbuettel.com/blog/2017/08/14/#009_compact_shared_libraries | | In particular, I was interested in the Makevars modification: | | strippedLib: $(SHLIB) | if test -e "/usr/bin/strip"; then /usr/bin/strip --strip-debug | $(SHLIB); fi | | Unfortunately it crashed compilation on Mac OS because for some reason | --strip-debug doesn't exist. Interesting. It so happens that I just shipped a use of `strip --strip-unneeded` in RcppClassic, see https://github.com/eddelbuettel/rcppclassic/blob/7cc5c626952d38cc97a99363131fe7ac9d0a7b28/src/Makevars#L33 Does --strip-unneeded work on macOS ? | But this small modification works: | strippedLib: $(SHLIB) | if test -e "/usr/bin/strip" & test -e "/bin/uname" & [[ | `uname` == "Linux" ]] ; then /usr/bin/strip --strip-debug $(SHLIB); fi Maybe --strip-unneeded is for preferable. Otherwise, yes, one needs to check for Linux here. But that is the crux of these Makefile / Makevars tweaks. They get non-portable real quickly. The easiest may just be to NOT worry, and just use -W,-S in the local ~/.R/Makevars.
