I have experienced this problem when downloading clang from clang.org. The problem is that MacOS 10.14 does not have the system headers in /usr/include/ anymore. So I have to write (with clang and clang++ intended compilers): Building for Clang of clang.org on MacOS 10.14 in parallel directory: <my-project>/configure CXX=clang++ CXXFLAGS=-g CC=clang CFLAGS=-g CPPFLAGS="-isysroot $(xcrun --show-sdk-path) -I /usr/local/include" LDFLAGS="-L /usr/local/lib”
