When I compile Emacs for macOS, I disable native-compilation for good: ./configure PKG_CONFIG_PATH=/usr/local/lib/pkgconfig \ LDFLAGS="-L/usr/local/lib" CPPFLAGS="-I/usr/local/include” \ CC=clang OBJC=clang CFLAGS="-g -O3” --with-ns --with-modules --with-jansson \ --with-native-compilation=no I keep getting all these messages about GCCJIT: checking for gcc_jit_context_acquire in -lgccjit… no configure: WARNING: Elisp native compiler can't be enabled as libgccjit was not found. Please try installing libgccjit or a similar package if you want to have it enabled. checking for libgccjit.h… no configure: WARNING: Elisp native compiler can't be enabled as libgccjit header files were not found. Please try installing libgccjit-dev or a similar package if you want to have it enabled I really DO NOT want notice compilation here…and I know that I’m doing.
