Hi Keith,
The original error is gone, thanks! But I get another one a bit later
(source up to date from git for pktgen, DPDK 2.2.0 as SDK) :

This is fixed by this patch:
root at dpdk3:~/pktgen-dpdk/app# git diff
diff --git a/app/pktgen-seq.h b/app/pktgen-seq.h
index a48fbe0..ba787ff 100644

#include <cmdline_parse_ipaddr.h>

Then it fails linking:
LD pktgen
/usr/bin/ld: cannot find -llua
collect2: error: ld returned 1 exit status
I tried a few things and got this link working but then I got errors
about implicit declaration of function ?lua_putstring? and this is a
macro in 5.3.0 but not present in 5.3.2, a bit more lua transition work
is probably needed :).

Laurent
