Trying ubuntu 16.04.1, and development seems hard...
Trivial test program:
$ cat app.cc
#include <gtkmm.h>
int main(int argc, char *argv[])
{
auto app = Gtk::Application::create(argc, argv, "uk.ac.cam.bpi.app");
Gtk::Window window;
window.set_default_size(200,200);
return app->run(window);
}
$ cat Makefile.am
bin_PROGRAMS = app
app_SOURCES = app.cc
app_CXXFLAGS = $(GTKMM_CFLAGS)
app_LDFLAGS = $(GTKMM_LIBS)
$ cat configure.ac
AC_INIT([app], [1.0])
AC_CONFIG_AUX_DIR([build])
AC_CONFIG_MACRO_DIR([m4])
AM_INIT_AUTOMAKE([-Wall foreign])
AC_PROG_CXX
PKG_CHECK_MODULES([GTKMM],[gtkmm-3.0])
AC_CONFIG_FILES([Makefile])
AC_OUTPUT
First surprise:
Package gtkmm-3.0 was not found in the pkg-config search path.
gtkmm-3.0-dev was installed using apt install, and put in /usr/lib/x86_64-linux-gnu/pkgconfig, so I have to set PKG_CONFIG_PATH? Shouldn't pkg-config know that that is where -dev packages put .pc files by default?
$ echo $PKG_CONFIG_PATH
/usr/lib/x86_64-linux-gnu/pkgconfig
then compilation fails with:

Puzzled as -lgtk-3 and -lglib-2.0 appear, and apt install libgtkmm-3.0-dev seemed to install the necessary packages.
Just tried the exact same example code above on NetBSD-current/amd64, and it succeeds with:
