Change
g++ `pkg-config gtkmm-3.0 --libs --cflags` -o "gtkmmdemo" ./src/gtkmmdemo.o
to
g++ -o "gtkmmdemo" ./src/gtkmmdemo.o `pkg-config gtkmm-3.0 --libs --cflags`
From the description of gcc, option -l (lowercase l):
It makes a difference where in the command you write this option; the linker
searches and processes libraries and object files in the order they are
speci-
fied. Thus, 'foo.o -lz bar.o' searches library 'z' after file 'foo.o'
but before
'bar.o'. If 'bar.o' refers to functions in 'z', those functions may not
be loaded.

I'm trying to compile a simple program, has set up the eclipse as in
this tutorial:

I'm using gtkmm-3.0.
gtkmmdemo.cc

#include <gtkmm.h>
int main(int argc, char *argv[])
{
Gtk::Main kit(argc, argv);
Gtk::Window window;
Gtk::Main::run(window);
return 0;

And the error message I get is this:
