Hello,
I am fairly new to the forum. I am trying the build the scull module from LinuxDeviceDriver examples and ran into the following issue:

"
adminuser@VirtualBoxImages-desktop:~/Desktop/examples/scull$ make
make -C /lib/modules/2.6.27-7-generic/build M=/home/adminuser/Desktop/examples/scull LDDINC=/home/adminuser/Desktop/examples/scull/../include modules

make: *** [modules] Error 2
"

How can I get the config.h for the 2.6.27.7 kernel? Is there a patch file that I could use?

Thanks,
Fatima

The config.h is now called autoconf.h. You could make a symbolic link to solve this:

Hi Seniors,

I ran following commands
1.tar zxf wrapfs.tar.gz
2.cd wrapfs

'wrapfs.tar.gz' from http://faculty.cs.nku.edu/~waldenj/c...labs/lab9.html
... is an old version from year 2006.
Is for older versions of 'kernel 2.6.xx' only.

Hello sir ,
Thank you for your post.

shantai@Shantai:~$ git clone http://git.kernel.org/pub/scm/linux/...ezk/wrapfs.git
Cloning into 'wrapfs'...
fatal: http://git.kernel.org/pub/scm/linux/....git/info/refs not found: did you run git update-server-info on the server?

when i run 2nd command on terminal it says

shantai@Shantai:~$ git clone git://git.fsl.cs.sunysb.edu/wrapfs-latest.git
Cloning into 'wrapfs-latest'...

$ git clone git://git.fsl.cs.sunysb.edu/wrapfs-latest.git

You will need some space (and speed ?) :

I have no idea. But I'd guess, it's like any kernel build.

Guessing again : Add the "wrapfs entry" ( WRAP_FS = YES ?)
to your config file, and 'make oldconfig', etc.

Hello Sir,
I used following commands for Wrapfs

shantai@Shantai:~$ git clone git://git.fsl.cs.sunysb.edu/wrapfs-latest.git
Cloning into 'wrapfs-latest'...
remote: Counting objects: 2334656, done.
remote: Compressing objects: 100% (450553/450553), done.

Resolving deltas: 100% (1949123/1949123), done.

Now for INstalling Wrapfs
I followed

1. cd wrpafs-latest
2.make oldconfig ---- created .config file
3.make-- compiled it successfully
4. ctags *.[ch] for this get error n skipped this step
5.cat /proc/filesystems
6.insmod wrapfs.ko
insmod: can't read 'wrapfs.ko': No such file or directory

Could u plz help me forward
Thank You

'make oldconfig' :
That's when you use the config file from your currently installed kernel.
..There are a couple of methods to get "the old .config file".
Please see the kernel documentation.
( There is usually a 'config' for your kernel in the /boot/ directory.
And one in /proc/ : /proc/config.gz ).

My guess was that you could add like CONFIG_WRAP_FS=y to the old '.config'.
(see #8)
