Do you need a makefile to compile a C program?
Now for your task, really there is no need for a Makefile, since make has built-in rules that know how to compile a simple program. All you need to do is place your C source in a file named after the executable name ( Hello) and with a .c extension, i.e. Hello.c. does everything. If you want to use gcc instead of cc, you can run
When to use$ ( CC ) in makefile?
If the makefile is written like most makefiles, then it uses $ (CC) when it wishes to invoke the C compiler. That’s what the built-in rules do, anyway. If you specify a different value for that variable, then Make will use that instead. You can provide a new value on the command line:
How to make GNU make use a different compiler?
You can set the environment variables CC and CXX, which are used for compiling C and C++ files respectively. By default they use the values cc and g++ If the makefile is written like most makefiles, then it uses $ (CC) when it wishes to invoke the C compiler. That’s what the built-in rules do, anyway.
