[Jorge B. [DTI2] <jo...@dt...>]

    Are you trying to build ipt_MPLS.o as a module? If so, the problem is
that the missing symbols aren't exported from the kernel. Add the next lines
at the end of  net/netsyms.c and do a "make mrproper" to be sure that all
the dependencies are going to bo built correctly (save you .config first).

#ifdef CONFIG_MPLS
EXPORT_SYMBOL(mpls_output);
EXPORT_SYMBOL(mpls_get_moi);
EXPORT_SYMBOL(mpls_set_nexthop);
#endif

    Best regards,

    -Jorge

Hi James,Oliver,


I was fighting with an unresolved symbol in the module ipt_MPLS.o
(mpls_set_nexthop and before mpls_output and mpls_get_moi); Im pretty
sure is a problem on the header files in my system, but I wasnt able to
find where the problem was. Now I modified a little bit the code and it
seems working.

James, sorry for the delay, I will start looking at the points we talked
Rgds,
Luca
