Re: [vpp-dev] VPP API Test Crash - Need help debugging
Billy, Apologies, that was a convenience I did for the attendees of the devboot course last year. In the course notes I had the git checksum of the commit, but as Dave points out, a bit stale. I find a combo of "ldd" against the VPP binary you have built and ultimately want to install and "ldconfig -p | grep" to be useful. Grep against "vpp" and "vlib" tends to show what's hanging around and the diff usually is defunct jetsam from prior packaging. Be a little careful though as I don't believe vlib is unique to VPP/fdio As the project evolves , so too packaging (I've felt your pain) A "find" over /usr/include for headers is not a bad sanity check too On Mar 27, 2017 6:52 AM, "Dave Barach (dbarach)" <dbar...@cisco.com> wrote: Dear Billy, Looks like a stale tree... vm = vlib_mains[os_get_cpu_number ()] from within vpp_api_test was always a mistake.
