failed to build latest dpdk 1.8.0 on kvm virtual machine

[Vasiliy Tolstov]

I'm try to build dpdk 1.8.0

unpack sources
sed -i 's|CONFIG_RTE_MACHINE="native"|CONFIG_RTE_MACHINE="default"|g'
config/defconfig_x86_64-native-linuxapp-gcc
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.

Thanks, this works fine.
