bash - make command not found

I have created make file named `Makefile` in my linux ec2 server. ``` all: a b a: daemon.cpp dictionary_exclude.cpp g++ -o a daemon.cpp dictionary_exclude.cpp -lpthread -std=c++0x -L. b: user_main.cpp client.cpp g++ -o b user_main.cpp client.cpp ``` I could run each of this independently successfull. But when I execute ``` make make -f Makefile ``` It says make : `-bash: make: command not found` Any idea? I can see manually for make is available through man make
