Makefiles help you to build a program from source without you having to issue every compiler call. They are interpreted by the command make and manage dependencies meaning they online issue the compile steps needed to save you time. Here is an example how to use a Makefile.
Contents
C file
We are using a source file written in C called main.c. Here is how we create it:
cat >main.c <<EOF
#include <stdio.h>
int main()
{
printf("hello world");
}
EOF
Makefile
Now we create the Makefile:
cat >Makefile <<EOF
all:hello
hello: main.c
gcc main.c -o hello
install: hello
cp hello /usr/local/bin
EOF
sed -i "s/ /\t/g" Makefile
Use it
To use the Makefile to build the executable binary file hello from the C source main.c, just call the command make and it will look like this:
tweedleburg:~/tuturial # make gcc main.c -o hello
