Example C program for use with @lst:example_makefile {#sec:example_c}

This very small program exists to ensure the validity of @lst:example_makefile but it also serves as a cool way to see make in action in its original intended use environment.

Listing: A simple "hello world" program in C, hello.c {#lst:helloworld_c}

#include <stdio.h>

int main(void)
{
    printf("hello, world\n");
}

Listing: Compiling @lst:helloworld_c with @lst:example_makefile make all and then invoking it {#lst:helloworld_c_compile}

echo "$ make all"
make -f Makefile.helloworld
echo "$ ./hello"
./hello
