Re: [dpdk-dev] DPDK PDUMP Issue

["Varghese, Vipin" <vipin.varghese@intel.com>]

Hi Dikshant,

Summarizing the contents from earlier mails below

1. Issue-1 shared with PDUMP not working with testpmd - solution shared and suggested what needs to be added to fix the same.

2. Issue-2 shared for custom Makefile for application not working - pointed out possible cause and missing order of libraries in CFLAGS and LDFLAGS. Suggested to use an existing working DPDK/example content for custom Makefile. 

Please note I do not have the project or Makefile for use case to try it locally, hence please try

```
5. Unable to find `-Wl,-lpcap` passed for `-Wl,-lrte_pmd_pcap -Wl,-lrte_pdump`

Hint: I normally take up sample like example/l2fwd and work towards to removing unwanted libraries while keeping the content and format intact for my custom makefile.
```
