[Gumstix-users] Compiling iptables and libpcap (fwd)

[Vikram K. <vk...@re...>]

I had sent this earlier, but have had no responses. My email inbox is 
misbehaving, so not sure if it reached the list.

Any pointers will be welcome

Also, in general, are there any instructions for adding optional packages 
other than compiling the entire kernel/image afresh after enabling those 
packages ?

Folks

  I want to be able to the use the libpcap library and iptables to set the 
appropriate "mangle" rules to trap packets and send them directly to user space instead of 
via the kernel where the UDP/IP headers will be stripped

  http://docwiki.gumstix.org/Software states that iptables,libpcap can be added 
via "buildroot".

  Do I have to recompile the entire kernel to add these two ? I am satisfied 
with whatever the kernel has and don't want to break it. I just want to add 
these two packages as well as libpcap-devel (to be able to write a user level 
program) to process the packets

  Can I compile these two and then copy them over ?
  Currently, the BR2_TARGET_LIBPCAP and BR2_TARGET_IPTABLES are both "not set"

  Or do I have to compile the entire source with these two enabled ?

  I would really prefer not having to recompile and reload the entire kernel

  Any pointers will be welcome

Thanks in advance..
