I have confirmed '--start-group/--end-groups' is specified while compiling, but I am still seeing the error.

---------------------------------------------------------------------- I just enabled the following option, then compile DPDK. CONFIG_RTE_BUILD_SHARED_LIB Is this collect to compile PMDs as dynamic link libraries? With the option, all libraries include are compiled as dynamic link library. Does "--start-group/--end-group" options work with dynamic link libraries? Regards, Tetsuya
