modul compile fails - autoconf.h

[Tamas Hegedus <biohegedus@gmail.com>]

Hi,

I have to compile a Cisco VPN Client on lenny stable (the provided
Cisco compatible vpn pkg is not good for me).

In directory "/lib/modules/2.6.26-2-686/build" there is no linux/config.h
/lib/modules/2.6.26-2-686/build -> /usr/src/linux-headers-2.6.26-2-686

Or where it should be?

I think I have a lot of packages (src, headers, autconf, etc) needed
for compiling...
I do not know what to do.

Thanks  a lot for your help in advance,
Tamas

In order to build the VPN kernel module, you must have the
kernel headers for the version of the kernel you are running.


Directory containing linux kernel source code [/lib/modules/2.6.26-2-686/build]

* Binaries will be installed in "/usr/local/bin".
* Modules will be installed in "/lib/modules/2.6.26-2-686/CiscoVPN".
* The VPN service will *NOT* be started automatically at boot time.
* Kernel source from "/lib/modules/2.6.26-2-686/build" will be used to
build the module.

Is the above correct [y]
