We are embedding mozilla in gtk application. Compiled
that application
using makefiles given in mozilla
/mozilla/embedding/browser/gtk/test/
folder. It works fine.
But when we are trying it from gtk application using
kdeveloper or
anjuta IDE, It crashes. sample code and errors are
attached. Is this problem of some libraries we are
using or
compilation flags used while compiling? If we are
missing some
libraries please let me know.
If anyone knows please help me.
Here is the code that we are using for embedding
mozilla.
#include >stdio.h<
#include >gtk/gtk.h<
#include >gtkmozembed.h<
#include >nsEmbedAPI.h<
int main(int argc, char *argv[])
{
GtkWidget *window;
GtkWidget *vbox;
GtkWidget *mozembed;
gtk_init(&argc, &argv);
gtk_moz_embed_set_profile_path(".", "mozembed");
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
if (window == NULL)
printf("\twindow is null\n");
else
printf("\twindow is not null\n");
gtk_widget_set_usize(window, 600, 700);
vbox = gtk_vbox_new(FALSE, 0);
if (vbox == NULL)
printf("\tvbox is null\n");
else
printf("\tvbox is not null\n");
mozembed = gtk_moz_embed_new();
if (mozembed == NULL)
printf("\tmozembed is null\n");
else
printf("\tmozembed is not null\n");
gtk_moz_embed_load_url(GTK_MOZ_EMBED(mozembed),
"file:/usr/share/doc/HTML/index.html");
printf("\tadding it to vbox\n");
gtk_box_pack_start(GTK_BOX(vbox), mozembed, TRUE,
TRUE, 0);
gtk_container_add(GTK_CONTAINER(window), vbox);
gtk_widget_show(mozembed);
gtk_widget_show(vbox);
gtk_widget_show(window);
gtk_main();
}
When we add given flags ==== -lgtkembedmoz
-lgtksuperwin -lmozjs
-lxpcom
Output is ---------
window is not null
vbox is not null

When we add given flags ====== -lgtk -lgdk -lgmodule
-lgtkembedmoz
-lgtksuperwin -lmozjs -lxpcom -lplds4 -lplc4 -lnspr4
-lpthread -ldl
-lc -lXext -lm -lXi
It gives segmentation fault for any gtk functions
like
gtk_box_pack_start(), gtk_container_add();
What are we doing wrong?
Thanks & Regards.
