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

Hi William,
`rte_dump_stack()` implementation requires linking DbgHelp system library.
There are other required libraries, see `add_project_link_arguments()` in
`config/meson.build`.
I also noticed that these libraries are not added to pkg-config
`Libs.private`. We must use `ext_deps` and `cc.find_library()`
instead of `add_project_link_arguments('-l...')`. IIRC you don't use
pkg-config, but still.

Thanks, pass linking stage now.

Thanks, and yes, the pkg-config on my system still doesn't work.
