[Openswan Users] Error compiling patch natt and klips kernel 2.6.18 Debian 3.1

[André Marascalchi Zenun]

Hello folks!

This is my first time installing openswan and I'm facing some problems!
I I'm trying to compile my kernel with support to NAT-T and Klips but
always that the compilation reach the ipsec part I get an error and the
compilation stops!

The error that I get is "net/ipsec/ipsec_alg_cryptoapi.c:148: warning:
function declaration isn't a prototype"! And others...

I try to apply the patches openswan-2.4.4.kernel-2.6-klips.patch and
openswan-2.4.4.kernel-2.6-natt.patch. The way that I apply them was like
this:

vpn:/usr/src/linux# patch -p1 < ../openswan-2.4.6.kernel-2.6-klips.patch
vpn:/usr/src/linux# patch -p1 < ../openswan-2.4.6.kernel-2.6-natt.patch

Please if some one could give some advice in how compile this two
patches I'll be grateful!

Thanks!

André
