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.

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.Finally when you open MATLAB type "mex -setup C" at the MATLAB command line (only needed once). ![]() usr/libexec/PlistBuddy -c 'Add :IDEXcodeVersionForAgreedToGMLicense string 10.0' ~/Library/Preferences/.ist Copy and paste the following to Terminal to tell MATLAB that you agree to the Xcode license:.If you install Homebrew then the Command Line Tools will be installed automatically.If you do not have Xcode you do not need to install it, and you probably don't want to as it is huge(~10 GB)! Instead install just the Command Line Tools, which are < 1 GB you will get some warnings when you run alphaMELTS for MATLAB, but they are harmless and can be suppressed. On Mac, if you have Xcode installed, and it is up to date, this will work for alphaMELTS for MATLAB. The second time you will be asked whether to Open or Move to Trash, so pick Open. Go to System Preferences -> Security & Privacy->General tab and select "Allow anyway", and then try again. If you see the option like "Move to Trash" and "Cancel" then click Cancel.
