c++ - CFLAGS not recognised in makefile -

i'm complicating small school assignment uses lambda functions, needs '-std=c++11' in gcc call. output of make file seems show not being added. i'm not having linking problems there no need copy source here.

here makefile:

cc=g++ cflags= -std=c++11 -i. -wall deps = wordarray.h obj = ayalajl03b.o wordarray.o  %.o: %.c $(deps)         $(cc) -c -o $@ $< $(cflags)  l03b.out: $(obj)         $(cc) -o $@ $^ $(cflags)  .phony: clean  clean:         rm -f -v *.o         rm -f -v *.out 

here output:

[user@server lab03]$ make g++    -c -o wordarray.o wordarray.cpp wordarray.cpp:28:77: warning: lambda expressions available -std=c++11 or =gnu++11     counter([](char a)->bool{return !isvowel(a) && !isdigit(a) && isalpha(a);}, worount].word); 

please me understand i'm doing wrong.

your rule

%.o: %.c $(deps) 

but compiling .cpp file.

the implicit make rule .cpp source files used.

either change rule

%.o: %.cpp $(deps) 

or set cxxflags variable used in implicit rule.
