Hi,

I want to use the function defined in in net/ip_options.c file like ip_options_compile, ip_options_build in my netfilter module. I want to put options into IP packet header. I have inserted the header file that declares these function. I have used EXPORT_SYMBOL, but I get warning, "ip_options_compile" undefined. Any suggestions will be greatly respected. I am using Ubuntu 11.10. uname -a: 3.0.0-16-generic. Is there a way to make this symbol visible for newer kernel?

-Jeewan
