Have a trouble with compiling simple dirver.

Hi, ppl. I'm from windows world, but very much like to switch to real
working with hardwere, here is my problem:

i need to compile such a simple dirver(using Fedora 8):
<code>
#include <linux/module.h>

static int hello_init(void)
{
return 0;
}

static void hello_exit(void)
{
return;
}

module_init(hello_init);
module_exit(hello_exit);

</code>




While trying to compile a this simple piece of software I have went through many difficulties such as compiling and installing kernel and
learned much things but still have errors. I learned that some headers needed to be installed, but there so many Linux clones and everyone of them use different schedules to do this. There comes errors:

Code:

Please use CODE /CODE tags arounf long listings as it's a pain to scroll through it all.

I find that creating a Makefile saves a lot of effort when compiling - especially kernel modules. Here's one that should work to test your hello.c program.
Code:
obj-m := hello.o 

KERNELDIR  := /lib/modules/$(shell uname -r)/build
PWD   := $(shell pwd)

default:
	$(MAKE) -C $(KERNELDIR) M=$(PWD) modules
Just create a textfile called Makefile in the directory of hello.c and run "make" from the console.

Hi sulacco,

I have a question, where is the <linux/init.h> #include command?

Regards,

It's right at the top. Look closer.

I'm using this kind of makefile, but will try your version
Code:
TARGET:= hello
WARN := -W -Wall -Wstrict-prototypes -Wmissing-prototypes
INCLUDE := -isystem /lib/modules/`uname -r`/build/include
CFLAGS := -O2 -DMODULE -D__KERNEL__ ${WARN} ${INCLUDE}
CC := gcc

${TARGET}.o: ${TARGET}.c

.PHONY: clean

clean:
        rm -rf{target}.o

I'm running your version of makefile but it says only that:

"Nothing can be done for `hello.c`"

What it is?

I think that the most important error string is this:

/lib/modules/2.6.28/build/include/linux/prefetch.h:14:27: error: asm/processor.h: No such file or directory

maybe I shoud to create somewhere a link?

Sorry I'm sure what's going on here as your code compiles fine on my system with the Makefile. Maybe something worng with your kernel source ?

How to understand wrong something or not with kernel source?
I've just downloaded it from kernel.org and configured, compiled, compiled
modules, installed modules, then make install.

this is the schedule which I did:

make menuconfig
make
make modules
make modules_install
make install

then I checked grub.conf and saw that make utility already changed it.

Then I restarted comp and choose kernel 2.6.28 to load.

C programms compiled successfully, but with driver program there is problem.

here what i've got while using your version of makefile.
First it have to be such a command:
make hello.

Code:
[root@localhost ushka]# make hello
cc     hello.c   -o hello
hello.c:1:26: error: linux/module.h: No such file or directory
hello.c:15: warning: data definition has no type or storage class
hello.c:15: warning: parameter names (without types) in function declaration
hello.c:16: warning: data definition has no type or storage class
hello.c:16: warning: parameter names (without types) in function declaration
make: *** [hello] Error 1

If I google linux/types.h:198: error: expected, I get several results.
http://lkml.indiana.edu/hypermail/li...10.1/1854.html

What I searched for is part of the first line with an error.

Assuming the link I provided helps, the problem is that you compiled in the same directory that the source is in. You're allowed to, but I think it's frowned upon. What I do is to use O=../build2.6.28 as one of the args for make each time. (do mkdir ../build2.6.28 first though!)

This is all you need to do. Create the file and type "make".

There's absolutely nothing wrong in compiling in the source directory. The error is due to incorrectly running make.

Just to be sure all is well try this :

Quote:
rm hello.{mod.*,o,ko}
make

if I run only:
Code:
make
here what I've got for answer:
Code:
make: Nothing to be done for `default'.
