Thanks, this works fine.

I'm try to build dpdk 1.8.0

unpack sources

export CFLAGS="-march=core2 -mtune=generic -pipe -O2"
make V=1 config T=x86_64-native-linuxapp-gcc
make V=1 MACHINE_CFLAGS="${CFLAGS}"

Hi,

CFLAGS for DPDK are usually set via EXTRA_CFLAGS. Try the following as a final 
set after the other config above:

EXTRA_CFLAGS="-march=core2 -mtune=generic -pipe -O2" 
MACHINE_CFLAGS=$EXTRA_CFLAGS make V=1

It compiles DPDK 1.8.0 from source on my test env.
