Hi *What am I trying to do?*
I am trying to write Gtests for my application based on DPDK. *Details about the app:* The application compiles dpdk as static library. Its a pretty simple. For now it just runs a dummy Gtest and create a memory pool. The key is, its a C++ file. I see no issue if it were a C app. *Issue I am facing:* The call to rte_mempool_create fails() with "Err: No such file or directory". *More debugging:* The reason for the above failure is, the constructor for the ring driver is not getting called. Specifically below code in ~/driver/mempool/ring/rte_mempool_ring.c. MEMPOOL_REGISTER_OPS(ops_mp_mc); MEMPOOL_REGISTER_OPS(ops_sp_sc); MEMPOOL_REGISTER_OPS(ops_mp_sc); MEMPOOL_REGISTER_OPS(ops_sp_mc); So when I look at the C app which has these constructors called, I see the init_array size to be much larger than the the C++ app. Considering the two code are almost identical, I don't know what am I missing to have these constructors run. They are definitely getting compiled but are not called. *What have I tried:* 1. I tried the --whole-archive LD option but I dont think that should play a part here since the constructors does get called with C app. Any suggestions? Regards Sachin.
