Hi Everyone, I'm testing Emacs 27.2 on OS X 11.2.3. It's the Apple Silicon aarch64 hardware. It is available at GCC304 on the Compile Farm. Configure is dying: checking AppKit/AppKit.h usability... yes checking AppKit/AppKit.h presence... yes checking for AppKit/AppKit.h... yes checking for Mac OS X 10.6 or newer... yes configure: error: Non-toolkit scroll bars are not implemented for Nextstep. I believe I have all the UI stuff disabled, so I should not need toolbars. I think I am building the equivalent of emacs-nox. Options include --without-toolkit-scroll-bars: --without-x --without-sound --without-xpm --without-jpeg --without-tiff --without-gif --without-png --without-rsvg --without-imagemagick --without-xft --without-libotf --without-m17n-flt --without-xaw3d --without-toolkit-scroll-bars --without-gpm --without-dbus --without-gconf --without-gsettings Jeff
