Current ./configure script shows misleading errors in case of wrong DPDK path:
# ./configure --with-dpdk=/wrong/path ... checking whether dpdk datapath is enabled... yes checking for library containing get_mempolicy... -lnuma checking for library containing pcap_dump... -lpcap checking for library containing mnl_attr_put... no configure: error: unable to find libmnl, install the dependency package This happens because we're not checking for headers before checking for dependencies. All the compile attempts fails and script thinks that we need more dependencies. With this change script will check for 'rte_config.h' availability and produce sane error message: # ./configure --with-dpdk=/wrong/path ... checking for rte_config.h... no configure: error: unable to find rte_config.h in /wrong/path 'AC_INCLUDES_DEFAULT' passed explicitly to avoid preprocessor test.
