Hi Dikshant,
Looks like the custom Makefile log is quite different in passing DPDK CFLAGS
and LDFLAGS. Also here are couple of surprises for me
1. Unable to find `make -n` logs
2. presence of g++ is present in each line
3. unable to find include option
4. request was to run `make -n` and cross the relevant libraries are bound
within the `-Wl,--whole-archive` and `-Wl,--no-whole-archive `.
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.
