My new MacBook Air has the Xcode command line developer installed, but I can't see any header file under /usr/include. How to get all the standard header files installed under the /usr/include?
MacBook Air, macOS 14.5
Normally Xcode uses the appropriate SDK located elsewhere. I’m not sure about the command line tools. I thought they used to populate /usr/include, but I wouldn’t be surprised if they didn’t anymore/ever.
/usr/include is protected in macOS 10.15 and later.
Set CPATH:
export CPATH=`xcrun --show-sdk-path`/usr/include
