Dear poppler people,
Currently I am trying to develop a program to sort documents. For this
program I would like to use poppler to render PDF files. I have made the
following code to try out and gain experience with poppler.
Unfortunately the results is a segmentation fault :-(. I hope someone
here can help me solve the problem.
The following messages are returned when executing the function
"poppler_document_new_from_file":
(process:15205): GLib-GObject-CRITICAL **: gtype.c:2248: initialization
assertion failed, use IA__g_type_init() prior to this function
(process:15205): GLib-CRITICAL **: g_once_init_leave: assertion
`initialization_value != 0' failed
(process:15205): GLib-GObject-CRITICAL **: g_object_new: assertion
`G_TYPE_IS_OBJECT (object_type)' failed
Segmentation fault
The code compiles without errors or warnings with the following command:
"gcc `pkg-config --libs --cflags glib-2.0 gtk+-2.0 poppler poppler-glib
gdk-2.0 gdk-pixbuf-2.0` test.c -o test"
The system in use is Fedora 9 kernel 2.6.25.11-96.fc9.i686 on a dual
core Intel pentium E2140. The (dev) packages are installed using the
package manager "gpk-application". I am running Gnome but KDE is
installed also.
I hope someone has an idea. Maybe it is something really simple which I
forgot. I thank you for your reply and ideas in advance.
Greetings,
Bart
