Hemant,
If you want to debug a vpp-debug image, then use:
make test-debug TEST=test_foo DEBUG=gdb
Thanks,

Hi Florin,
I first built a debugged vpp image using “sudo make build”. Then I
used the command you showed me below and interestingly the command
builds a *release* binary and then runs. So, data structures I want
inspect in gdb are optimized out. I don’t see this vagary with VPP
shell debugging I spoke of in my first email.
(gdb) p adj
$2 = <optimized out>
(gdb)

Hi Hemant,
Probably you’re looking for:
make test TEST=test_foo DEBUG=gdb

Hi folks,
I know how to use gdb with vpp when a vpp shell is logged into
using “sudo vppctl -s /run/vpp/cli.sock”.
However, I can’t work with gdb to debug vpp if I am using “sudo
make test TEST=test_foo”. Is it even possible?
Since I can’t make gdb work with “sudo make test”, this is the
reason my progress has been slow debugging ip-neighbor and
ip_adjacency. I am relying on fprintf(stderr, …) and its like
peeling an onion.
Regards,
Hemant
