Thanks. I find the problem in the source code where it uses CPP_STANDARD as suffix in –std=c++, therefore I should set CPP_STANDARD instead of the other one.

You generally shouldn't set CMAKE_CXX_STANDARD on its own, you should also be explicitly setting CMAKE_CXX_STANDARD_REQUIRED and CMAKE_CXX_EXTENSIONS to ensure you are getting the behaviour you want. These would also typically be set by the project's own CMakeLists.txt file rather than being passed on the cmake command line as cache variables. You may find the following article helpful: https://crascit.com/2015/03/28/enabling-cxx11-in-cmake/ On Fri, Apr 21, 2017 at 8:57 AM, Alex Chen <alex_c...@filemaker.com> wrote: I tried to set the compiler flag –std=c++14 via cmake command line on Linux with –DCMAKE_CXX_STANDARD=14. The message from ‘make’ shows -std=c++11 –std=gnu++14 If I do not set that flag, I get -std=c++11. This seem to imply the CMAKE_CXX_STANDARD flag sets gnu++ instead of c++. How do I set the flag –std=c++14 then?
