            Bug ID: 192
           Summary: construct function miss for  build with static library
           Product: DPDK
           Version: 18.11
          Hardware: All
                OS: All
            Status: CONFIRMED
          Severity: normal
          Priority: Normal
         Component: mk
          Assignee: [email protected]

Target Milestone: ---

I use libdpdk.a to compile a libpmd.so, but I find some construction function missed in libpmd.so
There're two file have such issue:
1. drivers/mempool/ring/rte_mempool_ring.c
No function in this file will be call from other place, so if I don't add -Wl, --whole-archive libdpdk.a for gcc , then the construction function will not be generated to libpmd.so
the construction functions are:
MEMPOOL_REGISTER_OPS(ops_mp_mc)
MEMPOOL_REGISTER_OPS(ops_sp_sc)
MEMPOOL_REGISTER_OPS(ops_mp_sc)
MEMPOOL_REGISTER_OPS(ops_sp_mc)

2. drivers/mempool/stack/rte_mempool_stack.c

Current we can add -Wl, --whole-archive to workaround, or add a null function in this 2 file, but it looks very stupid.

Thank you
