compiling c++11 using make command

I am trying to compile my code on CPU using MobaXterm terminal and I use make command to compile my code. But many errors appears starting with the ones bellow. I searched online and understand that this is an issue with the compiler. But I am using make not g++. Any suggestion to solve these compilation problems.

                     from host/src/host.cpp:16:

After many tries and suggestions, I finally find out the solution:

Edit my Makefile as follow:

    # Compilation flags
ifeq ($(DEBUG),1)
CXXFLAGS += -g -std=c++11
else
CXXFLAGS += -O2 -std=c++11
endif

That's more of a compiler issue and not and issue with make.

  1. Check that the compiler is properly set up for the system you are on.
  2. Also,if the compiler is well set up, check if it is compatible to compile C++11 standard as an older compiler could be the issue.

I think it would also be useful if you: -include What OS you are on -what compiler your are using

Let me know if this is useful.
