You can find the version information in
$(top_builddir)/gnuradio-core/gnuradio-core.pc. This is filled in with the
information in $(top_srcdir)/version.sh. Where top_builddir is where you are
building the project, and top_builddir = top_srcdir if you are building in
the same directory that contains the source code.


In addition to compile time, in the >= 3.3 API we added a way to ask this at
runtime via the gr.version() call in Python and gr_version() function from
C++.

 (I know you're not using the 3.3 API yet, but it will be another option for
you when you update your application.)
