Compile error if linking against GTK+ 3 and poppler-glib via pkg-config

[Stefano Facchini]

The following test program (test.cpp):

    #include <gtkmm.h>
    #include <poppler.h>
    int main()
    {
         return 0;
    }

compiled with:

g++ -o test test.cpp `pkg-config --cflags --libs gtkmm-3.0 poppler-glib`

gives the error:

In file included from /usr/include/gdkmm-3.0/gdkmm/window.h:37:0,
                 from /usr/include/gdkmm-3.0/gdkmm.h:28,
                 from /usr/include/gtkmm-3.0/gtkmm.h:92,
                 from test.cpp:1:

Using:
Ubuntu Oneiric 11.10
libgtkmm-3.0-1, libgtkmm-3.0-dev version 3.2.0-0ubuntu1

The same test program compiles just fine with gtkmm-2.4. The equivalent C program linked against gtk+-3.0 also compiles fine.

Moreover, I get no errors with other distributions I tried (Archlinux, openSUSE 12.01), even with gtkmm-3.0

This is just because the current libpoppler-glib-dev depends on libgtk2.0-dev instead of libgtk3.0-dev. It uses GDK in its API, for instance. This would happen to people using GTK+ 3, not just gtkmm 3.

However, GDK is only used by include files when POPPLER_WITH_GDK is defined. POPPLER_WITH_GDK is apparently defined during the poppler build, and I don't think Ubuntu's libpoppler-glib was really built with that defined. So maybe the dependency is unnecessary. Reassigning to libpoppler-glib-dev for investigation there.

If GTK+ (or GDK) really is needed, it would be great if libpoppler was ported to GTK+ 3, but that doesn't seem to have even happened upstream yet.

This bug was fixed in the package poppler - 0.18.4-0ubuntu1

---------------
poppler (0.18.4-0ubuntu1) precise; urgency=low

  * New upstream version:
    - "evince displays the included PDF without rotation" (lp: #711300)
    - Contents of the page is not displayed while it is OK
      with xpdf or acroread (lp: #878715)
  * debian/control:
    - libpoppler-glib-dev shouldn't depends on libgtk-dev, it stopped using
      gdk and uses cairo directly (lp: #870662)
