I get the same errors too.

The cause is a limitation of the impgen utility of libtool 1.4.2.
impgen cannot treat the special symbol names in libglibmm (and libatkmm).

I always do the following instructions to complete the gtkmm2 compilation.

  1. Copy libglibmm def file generated by dlltool.

    $ cd pango/pangomm
    $ cp ../../glib/glibmm/.libs/libglibmm-1.3-14.dll-def .libs/libglibmm-1.3-14.dll-def

  2. Delete the import libraries already generated.

    $ rm .libs/*.a

  3 Make libpangomm again.

    $ make

I think it is a libtool's problem, and it can be solved by using
the collect def files generated by dlltool.

I would suggest that gtkmm2 should provide the coloect def files and
use it to build DLLs.
