I found out that to staticly compile against DPDK using the combined lib, I
needed all these options :
-Wl,--whole-archive -ldpdk -Wl,--no-whole-archive -lnuma -ldl -lpthread -lm
-lmlx4 -lmlx5 -libverbs
The whole-archive makes sense, as we need to embed drivers that wouldn't be
found at linking time (failing to include it prevents port discovery).
However it leads to missing inclusion. That's why I added all the libs at the
end of the line. The mlx4 libs particularly leads me to think that there must
be a more programmatic way, portable accross versions of DPDK to find out which
libraries referenced in DPDK I should include, right? Morveover if the DPDK
user didn't include mlx4, it will fail to compile...
What should I use? (the whole rte.extapp.mk DPDK build process is not an option
as the build system is rather complex in this project)
Or maybe some of these libraries should be included in the dpdk static lib?
I use the last git version (but it's the same problem with previous ones).
