Fatal error utility not found in g++ While I do make in a program I want to install, which installs fine in Opensuse, I get the error 

warning: include path for stdlibc++ headers not found; pass '-stdlib=libc++' on the command line to use the libc++
      standard library instead [-Wstdlibcxx-not-found]

What I understand that it complains about not finding the utility library in c++ but for MacOS, the compiler is clang and it shows it has the file 

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/utility



MacOS version is 10.14.6, and Xcode version is Version 11.0 (11A420a). How to solve this case then?
The solution is in the warning message: pass '-stdlib=libc++' in the command line when you run the install command. So just add CXX="g++ -stdlib=libc++" to the install/make command.
