Q: How to make a module with c sourses.

I'm going to make a module with c sources, which consist of 5 header (*.h)
files,
13 source (*.c) files, and a makefile.

To solve the problem, '*.c' and '*.h' files are included in 'm.xs', then it
works.
I do not think that THIS IS AN ANSWER!".

Here is a very small example which I want;

Makefile -----------------------------------------
CC = gcc
CFLAGS =

OBJS = main.o lib.o

main: $(OBJS)

main.o: main.c *.h

lib.o: lib.c *.h

clean:
-rm main
-rm $(OBJS)

lib.h -----------------------------------------
int PrintHello();

lib.c -----------------------------------------
#include <stdio.h>
#include "lib.h"

int PrintHello(char *name) {
printf("Hello, %s!\n", name);
return 1;
}

main.c ----------------------------------------
#include <stdio.h>
#include "lib.h"

int main() {
char *name = "Aha00a";
PrintHello(name);

return 0;
}

-----------------------------------------------

My goal is to use a Perl script as following;

iwanna.pl -------------------------------------
use strict;
use MyLib::Hello;

my $name = "Aha00a";
PrintHello($a);

-----------------------------------------------

Thanks in advance.

You're right - it's not. Trying to create your own Makefile manually is an
exercise in frustration. Don't do it.

Instead, start with h2xs - even if you don't actually convert your .h files
with it, it will still create a "skeleton" module for you, that uses the
standard "perl Makefile.PL; make; make test; sudo make install" procedure
to build, test, and install.

Have a look at the following to get started:

perldoc perlxstut
perldoc h2xs
perldoc ExtUtils::MakeMaker::Tutorial
perldoc ExtUtils::MakeMaker
