Dear colleagues,
after submitting a release of my package RcppCWB (no problems with test servers), CRAN check results reported ERRORS on the macOS check systems: https://cran.r-project.org/web/checks/check_results_RcppCWB.html The core is that when test loading the package, you get the error: Symbol not found: _objc_msgSend$UTF8String Picking up a solution discussed here (disable objc_msgSend stubs in clang), I modified the configure script of my package to pass the flag “-fno-objc-msgsend-selector-stubs“ to the linker, which I thought would solve the problem. However: The CRAN Debian system for incoming R packages uses clang 15, which does not accept this flag any more, resulting in an error. Certainly, I could refine my configure script to address a very specific scenario on CRAN macOS systems, i.e. making usage of the flag conditional on a specific clang version. But I am not sure whether this is the way to go. It would feel like a hack I would like to avoid. Has anybody encountered this error? Is there a best practice or a recomended solution? I would be very glad to get your advice!
