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.
