Re: "extensions/libipt_ah.c" iptables 1.4.0 compilation problem

["SŽébastien Cramatte" <scramatte@zensoluciones.com>]

I answer to myself !

As you can see make include 2 paths to kernel include :

cc -O2 -Wall -Wunused -I"/lib/modules/2.6.16.19-xen/build"/include 
-I../linux-2.6.24.7/include -

One is the correct, the same as KERNEL_DIR argument  but the other match 
KBUILD_OUTPUT default value.

To build my iptables I must specifiy  2 arguments :

#make KERNEL_DIR=../linux-2.6.24.7  KBUILD_OUTPUT=../linux-2.6.24.7

This is not "clearly" explained in the INSTALL doc file ...

Netfitler team just tell this ...

1) Next, make the package.
        % make KERNEL_DIR=<<where-you-built-your-kernel>>
...

Please update the DOC !

Regards
