As per my understanding of the error message mentioned above:
using ::at_quick_exit _LIBCPP_USING_IF_EXISTS - This line introduces the at_quick_exit function from the global scope into the current namespace. The _LIBCPP_USING_IF_EXISTS macro is used to conditionally include this line only if the at_quick_exit function exists. Similarly it is implemented for the quick_exit function.
The error message suggests that the global scope does not have the functions at_quick_exit and quick_exit which is causing the parsing error.
Here are some of the troubleshooting steps you can follow to resolve the error:
- You can check and update the version of Xcode installed on your system.You may check if you have the necessary SDKs installed in Xcode. In this case, you need to have the MacOSX SDK installed. Open Xcode, go to Preferences, select the Locations tab, and ensure that the Command Line Tools and SDKs are properly set up.
- You can also check that the include path in the MATLAB environment is correctly configured to point to the cstdlib header file you mentioned: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1
- If the error still persists you may try to update or reinstall the C++ Standard Library for your Xcode installation. You can do this by using the Xcode package manager, such as Homebrew, to update the C++ Standard Library.
