Makefile - C++11

Question

I'm trying to understand MakeFiles and I'm trying to set the CFLAGS to C++11 in my make file. I have read the following: Makefile modification to support c++11 I have implemented one of the solutions, however, it does not seem to work, I'm getting the same error:

error: 'i' does not name a type for(auto i=begin; (i != end); i++)

Here is my MakeFile:

# Location of the Python Header files 
# This is system dependant. 

PYTHON_VERSION = 2.7
PYTHON_INCLUDE = /usr/include/python$(PYTHON_VERSION)

CFLAGS += -03
CFLAGS += -std=c++0x
CFLAGS += -pg -D_DEBUG -g -c -Wal
# location of the Boost Python include files and library

BOOST_INC = /usr/include
BOOST_LIB = /usr/lib

WAV_TARGET = /includes/Wav
WAV_SOURCE = Wav

# Compile the .wav Python and Cpp file 

$(WAV_TARGET).so: $(WAV_TARGET).o
  g++ -shared -Wl, --export-dynamic ($WAV_TARGET).o -L$(BOOST_LIB) -lboost_python -
          L/usr/lib/python$(PYTHON_VERSION)/config -lpython$(PYTHON_VERSION) -o  
          $(WAV_TARGET).so
$(WAV_TARGET).o: $(WAV_SOURCE).cpp
 g++ -I$(PYTHON_INCLUDE) -I$(BOOST_INC) -fPIC -c Wav.cpp

I'm probably missing something really stupid, but where am I going wrong here?

Your target isn't even using CFLAGS when invoking g++ . You can either add $(CFLAGS) to the target:

$(WAV_TARGET).o: $(WAV_SOURCE).cpp
    g++ $(CFLAGS) -I$(PYTHON_INCLUDE) -I$(BOOST_INC) -fPIC -c Wav.cpp

Or just add -std=c++11 to the flags you listed:

$(WAV_TARGET).o: $(WAV_SOURCE).cpp
    g++ -std=c++11 -I$(PYTHON_INCLUDE) -I$(BOOST_INC) -fPIC -c Wav.cpp
