[Openswan Users] 2.4.5RC5 KLIPS module won't compile against 2.6.15-1.2054_FC5 kernel

[Adrian_Sanchez]

I've just tried to compile OpenSWAN with KLIPS support on a Fedora Core
5 box running kernel 2.6.15-1.2054_FC5 installed with the kernel
sources, etc.

OpenSWAN compiled fine with just some warnings, but when running "make
KERNELSRC=/lib/modules/`uname -r`/build module minstall" as per INSTALL
directions, this is the error returned:

/root/download/openswan-2.4.5rc5/modobj26/ipsec_tunnel.c: In function
‘ipsec_tunnel_neigh_setup’:
