Hello,
I'm trying to get my feet wet in programming in C and the first thing I'm doing is reading a book called an Introduction to GCC. I'm running Fbsd 7-stable I have Gcc44 installed.
Example in the book is 3 files named main.c, hello_fn.c and hello.h:
File main.c with the following code:
#include "hello.h"
int
main (void)
{
hello ("world");
return 0;
}
File hello_fn.c with the following code:
#include <stdio.h>
#include "hello.h"
void
hello (const char * name)
{
printf ("Hello, %s!\n", name);
}
and hello.h with the following code:
void hello (const char * name);
Objective is to create a makefile which will create an executable named main. The books has this code in the Makefile:
CC=gcc
CFLAGS=-Wall
main: main.o hello_fn.o
clean:
rm -f main main.o hello_fn.o
The book says this should create two object files named main.o and hello_fn.o plus an executable named main. But the last is not created! Does it have to do with make version? or is the book outdated (2005) http://www.network-theory.co.uk/gcc/intro/
or you can the section that I'm referring to here:
http://www.network-theory.co.uk/docs/gccintro/gccintro_16.html
By the way I can create the executable using gcc -Wall main.c hello_fn.c -o main
so it's not a gcc problem I don't think.
