Try setting SDKROOT
explicitly to the system SDK:
export SDKROOT=$(xcrun --sdk macosx --show-sdk-path)
Doing it avoids the need for creating symlinks in /usr
.
This error seem recurrent, for example, if you installed another compiler (e.g. gcc from brew). Setting SDKROOT
became so common that it might be a good idea to add it to ~/.bash_profile
.
