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]
/Users/xyz/rivet/YODA-1.7.7/pyext/yoda/util.cpp:446:10: fatal error: 'utility' file not found
#include <utility>
         ^~~~~~~~~
1 warning and 1 error generated.
error: command 'g++' failed with exit status 1

make[1]: *** [all-recursive] Error 1
make: *** [all-recursive] Error 1

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?

  • clang is not g++ e.g. it has different parameters. and OpenSuse is Linux not MacOS - You need to configure the build system to use the correct compiler and OS specific things, then it might work. Not every thing wrtitten for Linux works on macOS – mmmmmm Sep 25 '19 at 20:50
  • I know OpenSuse is Linux, the point here to mention that the script works actually, and the exact script has worked on other Macs of my colleagues. – tachyon Sep 25 '19 at 21:38
  • Then you need to include more info in the question the obvious thing is how does your setup differ from your colleague? – mmmmmm Sep 25 '19 at 21:43

    That is what I don't know. The .profile file seems not to exist in my machine but there is a .bashrc. I am looking for any specific command in the .profile/.bashrc which can solve this issue. – tachyon Sep 26 '19 at 7:47

    nB the command is g++ --print-search-dirs note the last s – mmmmmm Sep 26 '19 at 17:44

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.

The solution is pretty simple, yet hard to find: You need to set the environment variable MACOSX_DEPLOYMENT_TARGET to 10.14 for Mojave and likely 10.15 for Catalina, like so

export MACOSX_DEPLOYMENT_TARGET=10.14
