Hi ,
Trying to write a test app  for  MEMNIC  ...
At the EAL init I got the error  while loading the memnic driver .. ..

Hi,

I compiled my testapp using this command

cc testapp.c -lrte_eal -lrte_mbuf -lrte_cmdline -lrte_timer  -lrte_mempool  -lrte_pmd_ring -lethdev -lrte_malloc -ldl -lpthread  -lrte_ring  -I/home/utils/dpdk-1.7.0/x86_64-native-linuxapp-gcc/include -L/home/utils/dpdk-1.7.0/x86_64-native-linuxapp-gcc/lib -o testapp

do I need to include any libraries to make it work.

You should use DPDK makefiles to build your application. Please try to follow 
this example:
