On StackOverflow I've been given some directions on getting Xcode to correctly use a cross platform Makefile, however haven't been completely successful so far.
I can add a target wrapping the Makefile, but haven't passed the environment variables to the `make` execution successfully yet, for it to remove the _line_ preprocessor directives. Also I haven't figured out yet how to configure that Make target as a build step before the program target itself. > On 6 Oct 2018, at 10:47, Hans Åberg <haber...@telia.com> wrote: > > >> On 5 Oct 2018, at 21:29, Uxio Prego <uxio.pr...@gmail.com> wrote: >> >> How would you detect Xcode from GNU Make? > > Is this for an external Makefile project? I probably don't really understand this question. Can't you eventually achieve the same results via either the "Cross-platform" > "External Build System" wizard or (e.g.) the "macOS" > "Command Line Tool"? > >> I would want to run `sed 's/#line/\/\/#line/'` on the generated parser >> in order for it not to show as assembly during debugging.

Nice to know, however maybe the `sed` use is more convenient. The default flow must be not to manipulate _line_ preprocessor directives. If I added `%no-lines`, would GDB debugging break? I'd try once I have a Linux box at hand again... So unless nothing breaks, injecting a `%no-lines` line in the Bison doc, I see unnecessarily complicated compared to optionally run a simple `sed` substitution on the generated parser. > Thank you, _______________________________________________ help-bison@gnu.org https://lists.gnu.org/mailman/listinfo/help-bison
