socket programming with DPDK?

socket programming with DPDK?

[Choonho Son]

Hi,

I am making netflow collector with DPDK.
I need to export result to another server with socket programming.
But I can not include <netinet/in.h> which defines struct sockaddr_in.

How can I make application with traditional socket programming and DPDK?

Thanks.

Why can't you add netinet/in.h?  Are you getting an error when doing so?  I
vaguely recall someone posting a fix for an include error for that file, but I
don't recall its disposition

Yes, we shouldn't try to redefine libc like in rte_ip.h.

Hi , im succesfully integrate boost asio c++ code with dpdk libraries. I do
packet processing with dpdk collecting statistics of protocol usage and
then use a extern function to send the statistics (custom struct) through a
boost socket in c++ code. Boost libraries use netinet/in.h internally .
Maybe the workaround is separete the compiling units and not mix the header
files.

Maybe this can help you.

Regards.
