dpdk-pdump makes use of LIBRTE_PMD_PCAP for interfacing the ring to
the device-queue pair. Updating Makefile to check for the same.

pdump is enabled default, so won't this break the default build?

What about moving this to lib/librte_pdump, convert $(error ..) to $(warning ..)
and disable CONFIG_RTE_LIBRTE_PDUMP there?

Yes, you are right it will fail. Which then forces the user to enable PCAP.

If we set to warning and there are no PCAP headers in build system. The application gets built, but will fail internally becz the pcap API will fails during execution.

We shouldn't break the default build because of missing dependencies.

if CONFIG_RTE_LIBRTE_PDUMP disabled application won't be compiled

How about combining If(($(CONFIG_RTE_LIBRTE_PMD_PCAP),y) check with below existing if check?
with this, dpdk-pdump will be compiled only when both the flags are enabled.

Hi Reshma,

I tried your suggestion, but the build fails even using warning or not using warning. The reason is DPDK build expects pdump to be build.

I am looking at other alternatives, how to get this done. In last effort, we may need to disable PDUMP to be build default from '.config' file.

Thanks
Vipin Varghese
