Hi Vipin,

I tried using `-Wl,--whole-archive` and `-Wl,--no-whole-archive `  option with my necessary libraries but it does not seem to help as well.

Below is the makefile log for my app:

g++ -shared -Wl,--export-dynamic packet_generator.o  -L/mnt/data/dchitkara/DPDK_2020_01_30_x86/x86_64-native-linux-icc/lib -Wl,--whole-archive -Wl,-lrte_mempool_ring -Wl,-lrte_member -Wl,-lrte_eventdev -Wl,-lrte_pmd_pcap -Wl,-lrte_pdump -Wl,-lrte_bus_vmbus -Wl,-lrte_pci -Wl,-lrte_bus_pci -Wl,-lrte_bus_vdev -Wl,-lrte_net -Wl,-lrte_distributor -Wl,-lrte_reorder -Wl,-lrte_kni -Wl,-lrte_pipeline -Wl,-lrte_table -Wl,-lrte_port -Wl,-lrte_timer -Wl,-lrte_hash -Wl,-lrte_jobstats -Wl,-lrte_lpm -Wl,-lrte_power -Wl,-lrte_acl -Wl,-lrte_meter -Wl,-lrte_sched -Wl,-lm -Wl,-lrt -Wl,-lrte_vhost -Wl,--start-group -Wl,-lrte_kvargs -Wl,-lrte_mbuf -Wl,-lrte_ip_frag -Wl,-lrte_ethdev -Wl,-lrte_cryptodev -Wl,-lrte_mempool -Wl,-lrte_ring -Wl,-lrte_eal -Wl,-lrte_cmdline -Wl,-lrte_cfgfile -Wl,-lrte_pmd_bond -Wl,-lrte_pmd_vmxnet3_uio -Wl,-lrte_pmd_virtio -Wl,-lrte_pmd_cxgbe -Wl,-lrte_pmd_enic -Wl,-lrte_pmd_i40e -Wl,-lrte_pmd_fm10k -Wl,-lrte_pmd_ixgbe -Wl,-lrte_pmd_e1000 -Wl,-lrte_pmd_ring -Wl,-lrte_pmd_af_packet -Wl,-lrte_pmd_null -Wl,-lrt -Wl,-lm -Wl,-ldl -Wl,--end-group -Wl,--no-whole-archive  -o ../../../COMMON/../bin/PACKET_GENERATOR_TEST_MOD.so

Ok, I think I have seen similar outcomes in custom Makefiles. Can you execute with `make -n` with the master Makefile and cross the necessary libraries are in bound between `-Wl,--whole-archive` and `-Wl,--no-whole-archive `  (specically for shared libraries).
