Hi Vipin,

Here is full log with include option and build with make -n option from master makefile as well:

Please have a note that module we are running is just one part of our CPP project treated as a separate test module.

Thanks,

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.
