3) Run Xcode onceĪfter downloading Xcode, you have to launch the Xcode application one time to install its components. If your computer does not have enough disk space for Xcode, or if the download will take prohibitively long (more than 24 hours) due to the quality of your internet connection, reach out to the instructors for alternate installation instructions. Xcode is a very large app, so the download and installation will take some time, anywhere from 1-4 hours depending on your network connection speed.
This can be done by setting the CPLUS_INCLUDE_PATH env variable. The C++ compiler needs to be told to look at this root path instead of /usr/include.To get the correct path for your system you can run the xcrun -show-sdk-path command. They will be installed in /Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk or a similar directory. This will install the C++ header files and libraries, albeit, in a different directory. Install Xcode through the App store to get access to the developer command-line tools.Optionally, install a C++ compiler like clang / gcc through brew if one is missing.Instead they are under the xcode path and you need to tell the C/C++ compiler where to find these libraries now. The issue is that macOS Catalina doesn’t use the /usr/include and /usr/lib/ directories anymore for all C++ headers and libraries.Ī lot of projects rely on these directories to exist, can’t find the files and then break.
