make error

Thanks Anmol, first installed the following extra packages
"linux-kernel-headers kernel-syms module-init-tools" then ran make
oldconfig && make prepare, I get further:
 make M=drivers/staging/bcm/

  WARNING: Symbol version dump /home/douglagm/git/linux-2.6/Module.symvers

I did a git clone git://
git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
then git branch douglagm - I am working on this.

The commands simply prepare the sources for compilation. Don't worry, it
will not modify your system in any way.

P.S. Make sure you're submitting patches against the linux-next tree.

Hi,

I have always wanted to contribute, but I am not a coder, I am a Linux
Admin, so I know some bash, perl and php. I came across the following video
: http://www.youtube.com/watch?v=LLBrBBImJt4&feature=related

So I decided even if I clean code it would hopefully make some
contribution. I followed the video and came to the following file that
needed some correction: drivers/staging/bcm/InterfaceDld.c. "
checkpatch.pl" gave 2 errors, both ERROR: "(foo*)" should be "(foo *)",
so I fixed the errors.

I did a "git diff" and it showed the corrections, from the video the next
step is to build the file, I believe the command must be "make
M=drivers/staging/bcm/", but I get the following errors:

  ERROR: Kernel configuration is invalid.
         include/generated/autoconf.h or include/config/auto.conf are
missing.
         Run 'make oldconfig && make prepare' on kernel src to fix it.


  WARNING: Symbol version dump /home/douglagm/git/linux-2.6/Module.symvers

  LD      drivers/staging/bcm//built-in.o
  Building modules, stage 2.
/home/douglagm/git/linux-2.6/scripts/Makefile.modpost:42:
include/config/auto.conf: No such file or directory
make[1]: *** No rule to make target `include/config/auto.conf'.  Stop.
make: *** [modules] Error 2

The error says " Run 'make oldconfig && make prepare' on kernel src to
fix it", but I am a bit nervous to try this, I would please like some
guidance before continuing.

I think the issue is related to my OS's kernel headers, from the kernel
README I am not sure what I need to do ?

I did a bit of searching the net and did not really find some answers,
well that made sense to me. kernelnewbies.org, not sure what is going on
there, get a lot of "*This page does not exist yet. You can create a new
empty page, or use one of the page templates. Before creating the page,
please check if a similar page already exists."*

Regards
Gregg

You should be cloing linux-next[1].

You are seing the above warning message because you have booted from
kernel-Version-X and you are building modules for kernel-Version-Y. To get rid
of this, after cloning the linux-next tree, build the kernel and boot from it.
Building and booting from your fresh kernel is sort of straight forward process
if you are not much concerned about the final kernel image size, etc. Following 
steps on my ubuntu box works fine, might work for you as well.
To build the kernel, in just few steps:

1: # sudo apt-get install build-essential
2: # make oldconfig
3: # make all 
4: # make modules_install install
5: # update-grub
6: # shutdown -r -y now

If you have system has multiple CPUs(see: cat /proc/cpuinfo), you can reduce the
build time by replacing the command in step 3 above as 
3: # make -jX all 
Where X = Number of CPUs

You also need to change your email-client to something else as gmail e-mail
client will not work for sending patches, refer email-clients[2] under
Documentation. I use mutt and this works quite well with gmail smtp server. You
can search for a mutt configuration file over world wide web to work with gmail.

You can also use git send-email command to send patches, but before that you
need to instal git-email add-on. On ubuntu box:
# sudo apt-get install git-email

Then setup smtp configuration
# git config --global sendemail.smtpserver smtp.gmail.com
# git config --global sendemail.smtpserverport 587
# git config --global sendemail.smtpencryption tls
# git config --global sendemail.smtpuser [off-list ref]
