[dpdk-dev] Linker error on rte_dump_stack() on Windows

[William Tu]

Hi,

While linking OVS to Windows DPDK library, static link to
librte_eal.a, we hit some error about rte_dump_stack().
I don't know why other symbols work, but only a couple symbols showed
errors here.
Any suggestions about how to debug/fix this? Thank you!

Running dumpbin, I can see the rte_dump_stack symbol.
c:\dpdk\install\lib>dumpbin /ALL librte_eal.a | grep rte_dump_stack
    D9E52 rte_dump_stack
 00000045  REL32                      00000000       139  rte_dump_stack

other symbols look similar...
c:\dpdk\install\lib>dumpbin /ALL librte_eal.a | grep rte_eal_cleanup
