In regards to your fix above, how does this change the probing behavior? It seems that it's just combining all the .a files into a single library, right? I still needed to include that whole lost if -D options that the examples use, or it still didn't seem to probe the bus. I must be missing something else as well. Do you mind pasting all of the defines/libraries that you pass into your app to get it to work? Currently the examples in mine pass this large list:
-march=native -DRTE_MACHINE_CPUFLAG_SSE -DRTE_MACHINE_CPUFLAG_SSE2 -DRTE_MACHINE_CPUFLAG_SSE3 -DRTE_MACHINE_CPUFLAG_SSSE3 -DRTE_MACHINE_CPUFLAG_SSE4_1 -DRTE_MACHINE_CPUFLAG_SSE4_2 -DRTE_MACHINE_CPUFLAG_PCLMULQDQ -DRTE_MACHINE_CPUFLAG_AVX -DRTE_MACHINE_CPUFLAG_RDRAND -DRTE_MACHINE_CPUFLAG_FSGSBASE -DRTE_MACHINE_CPUFLAG_F16C -DRTE_MACHINE_CPUFLAG_AVX2 -DRTE_COMPILE_TIME_CPUFLAGS=RTE_CPUFLAG_SSE,RTE_CPUFLAG_SSE2,RTE_CPUFLAG_SSE3,RTE_CPUFLAG_SSSE3,RTE_CPUFLAG_SSE4_1,RTE_CPUFLAG_SSE4_2,RTE_CPUFLAG_PCLMULQDQ,RTE_CPUFLAG_AVX,RTE_CPUFLAG_RDRAND,RTE_CPUFLAG_FSGSBASE,RTE_CPUFLAG_F16C,RTE_CPUFLAG_AVX2 -include $(RTE_SDK)/include/rte_config.h -O3 On Fri, Mar 18, 2016 at 2:56 PM, Matthew Hall <mhall at mhcomputing.net> wrote: > On Fri, Mar 18, 2016 at 02:45:10PM -0700, Cliff Burdick wrote: > > Hi, I've been trying to create a standalone application linked against > > DPDK, and I'm having some issues getting the program to run properly.
