The response would have more than what’s in CommandLineTools: Applications Library Makefiles Platforms Toolchains Tools usr If Xcode.app was installed: ls -al /Applications/Xcode.app/Contents/Developer/ If CommandLineTools was installed: ls -al /Library/Developer/CommandLineTools If Xcode.app was installed, you would see (at time of writing): Apple clang version 14.0.3 (clang-1403.0.22.14.1) InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin Previously, it was instead: Configured with: -prefix=/Library/Developer/CommandLineTools/usr -with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1Īpple clang version 13.0.0 (clang-1300.0.29.3)Ĭonfigured with: -prefix=/Library/Developer/CommandLineTools/usr -with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1Īpple clang version 11.0.3 (clang-1103.0.32.62)Īpple LLVM version 10.0.1 (clang-1001.0.46.4) InstalledDir: /Library/Developer/CommandLineTools/usr/bin If the program is using CommandLineTools, you would see (at time of this writing): Apple clang version 15.0.0 (clang-1500.0.28.1.1) If the response is “command not found”, it’s not installed. Verify the version of GCC installed: gcc -version Use `sudo Xcode-select -switch path/to/Xcode.app` to specify the Xcode that you wish to use for command line developer tools, or use `Xcode-select -install` to install the standalone command line developer tools.Īgain, if “Command not found” appears, either install CommandLineTools or install XCode.app, then return here. If neither is installed: xcrun: error: active developer path ("/Library/Developer/CommandLineTools") does not exist Applications/Xcode.app/Contents/Developer/usr/bin/gcc If Xcode.app is installed, the response would be: Library/Developer/CommandLineTools/usr/bin/gcc If Command Line Utilities is installed, the response would be: To identify the path to one of the utilities (gcc), use the xcrun utility that comes with macOS: xcrun -find gcc If the Xcode-select command is not found, choose to either install Command Line Tools or install the full Xcode IDE.Applications/Xcode.app/Contents/Developer If XCode.app was installed, you should instead see:.If XCode CLI was installed, you should see:.In a Terminal window, find out what has been installed: xcode-select -p Use Apple’s xcode-select command to identify where to find gcc and other Apple Developer utilities: Developers using Mac Books but NOT developing apps to run on an Apple platform can install just the CommandLineTools. ![]() Library/Developer/CommandLineTools => if installed using CommandLineToolsĬhoose one. $HOME/Applications/Xcode.app => if installed using Apple’s Xcode IDE Utilities needed can be obtained from two different folders, installed two different ways: “PROTIP:” here highlight information I haven’t seen elsewhere on the internetīecause it is hard-won, little-know but significant factsīased on my personal research and experience. Not intended to represent any employer (past or present). NOTE: Content here are my personal opinions, and This tutorial describes how to install several utilities needed by developers running HomeBrew, Python, and other programs on Macs: Install XCode from Apple’s web App Store.If you have other versions of Xcode, or you have renamed Xcode, then you need to use the name that you have given Xcode in the above command. If you want to check the version of Swift that Xcode-beta is using, we can using the following: /Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc -versionĪnd so on. So, if we look at the above command and want to check the Swift version used for the default Xcode app we can update it to look like the following: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc -version This is the most accurate way and it is quite easy: /Applications//Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc -version There are two ways that we can do this, one is more accurate if you want more than just the major version. Sometimes we need to check what version of Swift we are using, or, more correctly what version of Swift Xcode is using. ![]()
