[Click] click kernel module compile for Debian Lenny

[Stephen Pink]

Kevin,

Thanks for  your advice.  I was not able to successfully build a kernel with 2.6.19.2 sources, as the error that I get below (with the PDA) seems to come from using a later version of gcc and binutils (according to what I read in the linux forums).  So I brought over the most recent sources: 2.6.27.1 and I was able to build a (pre-patched) kernel which runs just fine.  

Problem now is that there is no Click patch for this newest distribution and the kernel sources (include files) have changed rather a lot since the older 2.6.19.2, so I am unable to make a click kernel module without having to "port" the patch to this new distribution.

If you know a shortcut on how to do this, I would appreciate hearing about it.

Hi Steve,

Kernel configuration options differ significantly from one version to the
next. So you cannot simply use one kernel's .config to build another
kernel. Configuration options not assigned a value are not compiled (See
Documentation/kbuild/makefiles.txt). Configuration option renames and
removals from one version to the next will likely cause module
dependencies to not be satisfied.

If you really want to use the 2.6.26 .config try 'make oldconfig'. This
will attempt to use as much of the old(new) config as possible. Another
option would be to configure the kernel using one of the other targets
('make menuconfig', see 'make help' for more options)

I would recommend configuring and testing a stock 2.6.19.2 kernel before
worrying about the click patches.

Hope this helps,
Kevin Springborn
