Getting the environment setup correctly is tricky with Clang. With GCC, you just run 'gcc -dumpmachine' and you can tell what you are targeting. -dumpmachine does not work with Clang. Clang reports the host's arch, like x86_64 even if you are targeting iPhone or iPhoneSimulator or WatchOS or AppleTV. To get the information from Clang you need to do something like this: https://github.com/weidai11/cryptopp/blob/master/GNUmakefile#L50. You have to run the preprocessor with CFLAGS or CXXFLAGS, and look for defines like __x86_64__ or __aarch64__. You have to use CFLAGS or CXXFLAGS because that's where you put '-arch arm64'. Xcode sets this for you in the IDE, but you have to do it manually when setting up a makefile. > Just like before on iOS14.5, I'm having issues with creating/editing > configurations in the simulator, with log messages like: > > Saving configuration failed: Error Domain=NEVPNErrorDomain Code=5 "IPC failed" > > The message I'm getting may be just as well be unrelated, but a common theme > I'm > seeing is that you can't get Network Extension providers to work on > simulators. Yeah, Apple has some cryptic error messages at times. If you can't find it while searching, then you have to burn one of those Apple Support incidences. > This Eskimo fellow seems to have good insight on the matter. > > https://developer.apple.com/forums/thread/46004?answerId=134358022#134358022 Quinn is usually very helpful. He's been supporting Apple development for as long as I can remember. Jeff
