How to make NetBeans use C++11 - c++

Question

I set up NetBeans 8.1 on Linux Mint to compile C/C++. Everything went fine at first, until I tried using C++14.
I changed the settings for C++ from C++98 to C++11. There was an error in the program which I fixed. I got distracted and changed the settings again to use C++14. g++, or at least the version I have installed, does not support C++14, so I changed it back to C++11, but it's still using C++14 of its own accord. I tried changing it to C++11 and back again, and then to C++11 again. C++11 works for sure, because I've used that tag with success in the past.
Here is the build log:
cd '/home/.../NetBeansProjects/Sun Storm'
/usr/bin/make -f Makefile CONF=Debug
"/usr/bin/make" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf

BUILD FAILED (exit value 2, total time: 76ms)
By seeing g++ -c -g -std=c++14, it is safe to assume that NetBeans is still using C++14, even though it is set to use C++11. How can I get NetBeans to use the settings that are actually there instead of making them up on its own?
Note: I couldn't find anything on the Internet about NetBeans not following the given settings.
I also tried deactivating the C/C++ plugin, restarting the IDE, and then activating it again. I also tried installing the GNU Standard C++ Library v3. Nothing changed.

Have you tried to change your "g++" call to devtoolset-2 ?
