how to make simple makefile for c program

make reads in rules (specified as a list. In either case, don't use autoconf, please. make is a Unix tool to simplify building program executables from many modules. However, if you want to change the name of the generated executable, libraries, or compiler flags, you can just modify the variables. h files in the current directory, meaning when you add new code files to your directory, you won't have to update the Makefile. It uses the wildcard and patsubst features of the make utility to automatically include. OBJECTS = $(patsubst %.c, %.o, $(wildcard *.c)) Here's the Makefile I like to use for C source. If you're interested in figuring that out, I hope I've given you a good start on that. I tried to make this as simple as possible by omitting variables like $(CC) and $(CFLAGS) that are usually seen in makefiles.

Thus, to improve: HEADERS = program.h headers.h However, to support more C files, you'd have to make new rules for each of them.

(bear in mind that make requires tab instead of space indentation, so be sure to fix that when copying) Interesting, I didn't know make would default to using the C compiler given rules regarding source files.Īnyway, a simple solution that demonstrates simple Makefile concepts would be: HEADERS = program.h headers.h
