<tt>Dear Julien,<br>
<br>
in a vanilla kernel you would achieve this by using "make
<your_targets> V=1" (you can find this clue in "make help").<br>
If you are lucky, Openvswitch's makefile may pass that flag along and
bring you the information you are seeking for.<br>
<br>
Regards,<br>
Massimo.<br>

<pre wrap="">I had the same problem, and I believe the problem is not coming from the
linux header file but rather with a include path during compilation.
Sadly i cannot find how to display the command line called by makefile
during module compilation (i.e. what is behind "CC [M]
/root/Downloads/openvswitch-1.1.0pre2/datapath/linux-2.6/genetlink-brcompat.o").
If someone has some clues how to pring more information during kernel
module compilation...
Cheers,
Julien.

<pre wrap="">I am making another attempt to install Open vSwitch on a netkit machine. The
issue is that their compilation requires including kernel header files that
the distributed netkit kernel omits. I did the following:
- compiled the kernel manually, which creates the necessary header files
- copied these over to the distributed kernel in the appropriate location
However, I still get the following errors. Various header files are still
missing. Does anyone know why these would not show up after I compiled the
kernel myself (simply using the Makefile provided with Netkit)?
