Linux Device driver - /usr/src/linux is empty
 
Hi, i am trying to write modular programm,
but when i try to compile i come to know i dont have any files in /usr/src/linux.

i have installed fedora 12 which has 2.6.31.5-127.fc12.i686.PAE

i am including in my code
linux/kernel.h
linux/module.h

Those are not present directory in /usr/src/linux is not present.

My goal is to compile modular programs.

I am newbie
Please help me how to do .....

Look in your yum repository for the linux headers or devel version related to your current kernel

knudfl 07-06-2010 12:49 PM
# yum install glibc-headers
will provide /usr/include/linux/kernel.h

# yum install kernel-devel
provides /usr/src/kernels/linux-´uname -r´
Only a few files are included.

'module.h' : You may need the full kernel source,
not available as an rpm package. ( Only as SRC.RPM.)

i have installed fedora 12 which has 2.6.31.5-127.fc12.i686.PAE
is like i need to download only this particular
2.6.31.5-127.fc12.i686.PAE sourcecode and manually copy paste to this location?

where can i get this kernel source code .src.rpm for this particular kernel

knudfl 07-06-2010 01:39 PM
'kernel-2.6.31.5-127.fc12.src.rpm' is available.
wget http://download.fedora.redhat.com/pu...7.fc12.src.rpm

2.6.31.5-127 : This is the release version.
If you ever update, it will change.
( Latest is : kernel-2.6.32.14-127.fc12.src.rpm ).

Hi i have downloaded kernel-2.6.31.5-127.fc12.src.rpm
i extracted and i found there are lot of patches along with linux-2.6.31.tar.bz2.
I extracted linux-2.6.31.tar.bz2 and copied whole directory linux-2.6.31 to /usr/src/ , The code what i have written is
module1.c
[Code]
#include<linux/kernel.h>
#include<linux/module.h>

int init_module(void)
{

printk("In Init module \n");
}

void cleanup_module(void)
{

printk("In Cleanup module \n");
}


i compiled using
gcc -DMODULE -D__KERNEL__ -I /usr/src/linux-2.6.31/include/ -c module1.c

The error what i am getting is

if i give uname -r i am getting the following

[root@rajguruvin rgv]# uname -r
2.6.31.5-127.fc12.i686.PAE

if i give yum install kernel-devel i am getting

[root@rajguruvin rgv]# yum install kernel-devel
Loaded plugins: presto, refresh-packagekit
Setting up Install Process
Package kernel-devel-2.6.32.14-127.fc12.i686 already installed and latest version
Nothing to do
