A simple
example on using
make
- Write a
Makefile to
automate the
compilation of the
Hello.c
program:
#include <stdio.h>
int main( int argc, char* argv[] )
{
printf( "Hello World !\n" );
}
|
- The final
executable program
is named
hello
|
A simple
example on using
make
- The chain of
file dependencies,
starting from the
target
hello:
hello depends on: hello.o
constructed using: gcc -o hello hello.o
hello.o depends on: hello.c
constructed using: gcc -c hello.c
|
- How to
specify these
dependencies
in a Makefile:
hello: hello.o
gcc -o hello hello.o
hello.o: hello.c
gcc -c hello.c

DEMO:
demo/C/Make/1
(1) Type make
again
after completion.
(2) Edit
hello.c and
re-compile !!!
