Re: [dpdk-dev] Build DPDK for different target machine.

Yes, that is exactly what am I trying to do. Build on a designated build machine, copy dpdk libs over to target machine and use them. Upon usage I get the 'Illegal instruction' error.

I am doing same but including dpdk libraries with application, you can do same. Other thing to try, copy the shared libraries from the build machine into targets instead of building them on targets.

Hello,

I am trying to build DPDK library set (shared) so that there are somewhat portable. I want to build them once on a designated build machine and run them on other machines of similar architecture. I can build DPDK and use it locally successfully but running them on a different target machine always gives me core dump with 'Illegal instruction'.

I am building with
make install T=x86_64-native-linuxapp-gcc
export RTE_TARGET=x86_64-native-linuxapp-gcc
and CONFIG_RTE_BUILD_SHARED_LIB=y

I have tried setting CONFIG_RTE_MACHINE, as "default" or "snb" but that does not help.

Help is much appreciated. Details of Build machine and target machine below:

Thanks
Chai.
