Compile problem

Dear all,

I am trying to compile a program which uses some ROOT libraries. Here is the Makefile

ROOTLIBS:= $(shell root-config --libs)                                                                                                            
                                                                                                                                                  
name=mca2                                                                                                                                         
                                                                                                                                                  
all: mca2                                                                                                                                         
                                                                                                                                                  
clean:                                                                                                                                            
        rm *.o mac2

mca2: $(name).o                                                                                                                                   
        g++ -O2 $(name).o $(ROOTLIBS) -o mca2

and he is the error I got after make

make
g++ -O2 -pipe -Wall -W -Woverloaded-virtual -fPIC -Iinclude  -pthread \

I am using the last ROOT version released and I set correctly the environment variable ROOTSYS, maybe am I missing something?

You need to enable C++11. This is done by adding the compilation flag -std=c++11

$(name).o: $(name).cpp 
g++ -O2 -pipe -Wall -W -Woverloaded-virtual -fPIC -Iinclude -pthread \ 
-I $(ROOTSYS)/include -std=c++11 -o $(name).o -c $(name).cpp
