I happened to notice that this header file uses #import <Cocoa/Cocoa.h>
This is the first time I came across the preprocessor directive #import; the first thing I found about it is this Q&A suggesting it's not portable nor standard C: https://stackoverflow.com/q/39280248/3576984 On the other hand, this exact invocation seems pretty common on GitHub https://github.com/search?l=C&q=%22%23import+%3CCocoa%2FCocoa.h%3E%22&type=Code I don't see much in the way of relevant documentation for Cocoa besides stuff like this page from 2001: http://cocoadevcentral.com/articles/000031.php Is this something that should be updated to use #include? Other packages appear to have done so, e.g. from GitHub: https://github.com/search?q=%22%23include+cocoa%2Fcocoa.h%22&type=code Michael Chirico [[alternative HTML version deleted]] ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
