Subject: [dpdk-dev] [Bug 192] construct function miss for build with static library
Date: Fri, 18 Jan 2019 02:15:52 +0000 [thread overview]
Message-ID: <bug-192-3@http.bugs.dpdk.org/> (raw)

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: dev@dpdk.org
Reporter: qingfu.cqf@alibaba-inc.com
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
