Hi Burt, Thanks for your hints.
Here is the output of “dpkg-query -l pkg-config”, looks same as yours: cfdumitr@silpixa00382658:~/git_fdio/vpp$ dpkg-query -l pkg-config Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-======================-================-================-================================================= ii pkg-config 0.29.1-0ubuntu1 amd64 manage compile and link flags for libraries I re-ran “make install-dep”, it worked again with no (obvious) error messages: cfdumitr@silpixa00382658:~/git_fdio/vpp$ sudo make install-dep Get:1 http://security.ubuntu.com/ubuntu xenial-security InRelease [102 kB] Hit:2 http://ie.archive.ubuntu.com/ubuntu xenial InRelease Hit:3 http://ie.archive.ubuntu.com/ubuntu xenial-updates InRelease Hit:4 http://ie.archive.ubuntu.com/ubuntu xenial-backports InRelease Fetched 102 kB in 0s (245 kB/s) Reading package lists...

Well the config.log you have IS consistent with mine. g2 doesn't show up the way it does in mine because your configure did not complete successfully. Can you double check $ dpkg-query -l pkg-config comes back with something like Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-====================-===============-===============-============================================= ii pkg-config 0.29.1-0ubuntu1 amd64 manage compile and link flags for libraries which it should if your "make install-dep" worked properly. You see the src/configure.ac<http://configure.ac> has PKG_CHECK_MODULES macro that is in /usr/share/aclocal/pkg.m4, and that file suggests that our configure.ac<http://configure.ac> should have more helpful hints than it currently does dnl To ensure that this macro is defined, also add: dnl m4_ifndef([PKG_PREREQ], dnl [m4_fatal([must install pkg-config 0.29 or later before running autoconf/autogen])]) But we circle around to your make install-dep should have worked and obviated the need for extra helpful messages in configure.ac<http://configure.ac>. Of course, you want to do a git status to make certain that nothing bad crept into your repo. Burt
