cannot use std containers
The project created in cube, then converted to c++.
Include statements do not show error and allow navigation to the code, e.g. #include <string> finds
“C:\SW4STM32\plugins\fr.ac6.mcu.externaltools.arm-none.win32_1.17.0.201812190825\tools\compiler\arm-none-eabi\include\c++\7.3.1\string
However attempt to use string class fails.
