What is the modern equivalent of RTE_BUILD_SHARED_LIB?

brydon_gibson — Mon, 13 Sep 2021 13:03:12 GMT

I've built an app with dpdk 20.11 and I'd like to convert it to a shared library. I've removed the main function, changed the app name to a library name, and configured RTE_BUILD_SHARED_LIB=y. However, make still complains about "undefined reference to main".

The CC command is as follows:

cc -O0 -ggdb -include rte_config.h -march=native -I/usr/local/include -DALLOW_EXPERIMENTAL_API eCPRI.c cmdParser.c -o build/libeCPRIgen-shared -L/usr/local/lib/x86_64-linux-gnu -Wl,--as-needed -lrte_node -lrte_graph -lrte_bpf -lrte_flow_classify -lrte_pipeline -lrte_table -lrte_port -lrte_fib -lrte_ipsec -lrte_vhost -lrte_stack -lrte_security -lrte_sched -lrte_reorder -lrte_rib -lrte_regexdev -lrte_rawdev -lrte_pdump -lrte_power -lrte_member -lrte_lpm -lrte_latencystats -lrte_kni -lrte_jobstats -lrte_ip_frag -lrte_gso -lrte_gro -lrte_eventdev -lrte_efd -lrte_distributor -lrte_cryptodev -lrte_compressdev -lrte_cfgfile -lrte_bitratestats -lrte_bbdev -lrte_acl -lrte_timer -lrte_hash -lrte_metrics -lrte_cmdline -lrte_pci -lrte_ethdev -lrte_meter -lrte_net -lrte_mbuf -lrte_mempool -lrte_rcu -lrte_ring -lrte_eal -lrte_telemetry -lrte_kvargs

It looks like it's still trying to build an executable as opposed to a shared library. Do I need to change more in my makefile, or is there a different option than RTE_BUILD_SHARED_LIB in newer versions of dpdk?

Hi Crisselle,

Intel Premier support does not have "DPDK" as a selectable product when creating a case. What product should this be created under?
