I think problem is overwriting your setting when selecting doing step 3 & 4. After above steps can you please check your generated config file (x86_64-native-linuxapp-gcc/.config) for the CONFIG_RTE_MACHINE value? What you can do is, - do above steps - edit "x86_64-native-linuxapp-gcc/.config", update CONFIG_RTE_MACHINE as "default" - rebuild, "make install T=x86_64-native-linuxapp-gcc" You can verify that this is working by enable vebose during build, with V=1: - make install T=x86_64-native-linuxapp-gcc V=1 And during compilations verify following flag exists; "-march=corei7" Another problem, unrelated, in your step 3 above a config file created under "./build/.config" but you are not using it, step 4 again creates a new config file under "x86_64-native-linuxapp-gcc/.config" You can do either: - make T=x86_64-native-linuxapp-gcc config - make output will be under ./build/ - To install libraries into system folders: "make install" OR - make T=x86_64-native-linuxapp-gcc O=x86_64-native-linuxapp-gcc config - make O=x86_64-native-linuxapp-gcc output will be under ./x86_64-native-linuxapp-gcc/ - To install libraries into system folders: "make O=x86_64-native-linuxapp-gcc install" briefly if you omit "O=" it uses "build" by default. > Thanks > Chai. > > -----Original Message----- > From: Ferruh Yigit <ferruh.yi...@intel.com> > Sent: Monday, October 22, 2018 02:58 AM > To: Shubhachint, Chaitanya <chaitanya.shubhach...@netscout.com>; dev@dpdk.org > Subject: Re: [dpdk-dev] Build DPDK for different target machine. > > [EXTERNAL EMAIL] > > On 10/19/2018 5:24 PM, Shubhachint, Chaitanya wrote: >> Hello, >> >> I am trying to build DPDK library set (shared) so that there are somewhat >> portable.
