Hi. I get segmentation fault if I try to access a Poppler object whose
pointer is passed through g_signal_connect. There is no such problem
with normal pointers, though.
For example, if I run the following code...
#include
struct Colors
{
double red;
double green;

Thanks!
So i could replate enter and leave to g_iddle_add, right?
gdk_threads_enter();
g_printf("UpdateConfigNow\n");
iUpdateConfigNow();
gdk_threads_leave();
To
g_idle_add((GCallback)iUpdateConfigNow, NULL);
Why i get this error?
Main.c:1824: undefined reference to `g_iddle_add'
Thanks

Hi guys,
My application sometimes have segmentation fault error. In debug mode

This basically means that the pointer that you passed to
gtk_entry_get_text was not pointing to a GtkEntry.

Running through gdb, we can see it crashes on this line:
gtk_container_add(GTK_CONTAINER(window),menu_bar);
glancing through the code, this makes perfect sense because window is
never initialized. The pointer window points to some random address.
Adding:
window = gtk_window_new(GTK_WINDOW_TOPLE

which is supposed to display a simple menu. It compiles but when I run it,
it gives a segmentation fault.
Please review the program and suggest some solution:

Hi Aparna,
Forgive me if I am wrong, but g_thread_init(NULL); gdk_threads_init();
might duplicate the call. I recall when using gnet (which initiates
the threads itself it segfaulted if I called g_thread_init. Perhaps
taking one of those out would fix your problem?

Hi,
I am compiling a gtk application using gcc-3.4.5-glibc-2.3.6 for arm

to know why the inclusion of g_thread_init() gives me a segmentation
fault while i run the application on the target platform.

The problem was in the callback's arguments, thanks.

I cut out most of the code to make things clearer, don't worry I did

Szymon,
In addition to what Yeti has pointed out, one thing that's obviously wrong
is that you don't seem to have anything in your code that adds the text
entry
to the window, i.e.
gtk_container_add(GTK_CONTAINER(windowP), widgetP);
Also, why not use gtk_entry_get_text(...) to read the content o
floating point
number parser? You have a whole range of functions from
atof and strtod to sscanf to g_ascii_strtod() available.

Clicking on button STOP, the variable *stop is setted to TRUE.

My best advice is to read the GDB Manual -
http://www.gnu.org/software/gdb/documentation/. Chapters 4 and 5
should give you a fairly good idea how to perform simple debugging on
your program. If you don't feel like get some GUI debugger like
Insight (http://sources.redhat.com/insight/).

Are you dealing with threads?
Maybe it's a problem of concurrency.

Using GTK 2.2.4, we are getting a segmentation fault in
g_object_run_dispose called from gtk_widget_destroy on a fixed container.
The context is a screen that works fine when operated on slowly, such that
all widgets are displayed before any action is taken. The problem only
occurs if you "
abel_new("i put something here");
Or even:
const char* ch = "i put something here";
label=gtk_label_new(ch);
Or even:
char *ch;
ch = g_strdup("i put something here");
label=gtk_label_new((const char*)ch);
g_free(ch);

first line has no type
4th line is a comparission
5th line copys to unallocated space
ok, it works first time, but when the program executes
this func
tion again it creates a segmentation fault.
also
label=gtk_label_new((const char*)ch);
doesnt work either,
I get segmentation fault when, i destroy the dialog
which contain the label.

gdk_pixbuf_save() is a vararg function. Compare your function call to the API
