Ql-sdk throws C++ compiler error

IoT Modules LTE Standard Module

Any idea why I am getting this error, Does 4.9.2 gcc compiler supports C++11/14?

Thanks,

Should be yes.
Better to check your source code. If still like so, you can upload some piece of code and let us to check.

application uses stl like this code is failing to complile at #include level. Please see below error. It started from app.cc file and compiling up to cross tool alloc_traits.h file.
Do you think am I missing compiler flag?
Below is c++ compile flag:
set(CMAKE_CXX_FLAGS “${CMAKE_CXX_FLAGS} -ggdb -std=c++11 -Wall -Werror -Wno-error=deprecated-declarations”

Thanks for your support.

It might not work with it in your Makefile. I have tested some C++11 examples .

source ql-ol-crosstool/ql-ol-crosstool-env-init
 arm-oe-linux-gnueabi-g++  -v
 arm-oe-linux-gnueabi-g++  test1.cpp  -std=c++11
