It looks like you recently added GTK+ 3 support to Ghostscript. In psi/dxmain.c, most of the calls to GTK+ 3 functions are guarded with with GTK_CHECK_VERSION(3, 0, 0). But in the function window_resize(), there's an unconditional call to: width = gtk_widget_get_allocated_width (img->window) - 96; height = gtk_widget_get_allocated_height (img->window) - 96; I don't think those functions are available in GTK+ 2. When I try to build Ghostscript from source on Linux with GTK+2, I get the errors: ./psi/dxmain.c: In function 'window_resize': ./psi/dxmain.c:363:17: warning: implicit declaration of function 'gtk_widget_get_allocated_width'; did you mean 'gtk_widget_get_allocation'?

Fixed in: http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=a73071b87a61 Actually, GTK 3.x.x support was added about 6 years ago (basically when GTK 2.x.x became deprecated and unsupported), this recent change was to address deprecated API calls in the 3.x.x API. GTK+ 2.x.x is likely to be dropped at some point - particularly given that GTK2 development appears to have stopped ~2 years ago (and was minimal for quite some time before that).
