[maemo-developers] [maemo-developers] Hello World

[From: Gergely Buday]

Hi,

I'm to write a Hello World program based on section 5.3.1 (Writing
maemo GUI applications/Windows/HildonApp of the Maemo SDK Tutorial.
Unfortunately it doesn't work. Possibly I forgot to do something, so I
ask for your experienced eyes to pick the errors.

Running af-sb-init.sh restart I get the following error message:
============================================

And here is what I wrote:

My main.c:
---
#include <hildon-widgets/hildon-app.h>
#include <gtk/gtk.h>
#include <libosso.h>

int main(int argc, char** argv)
{
        HildonApp* app;

        gtk_init(&argc, &argv);

        app = HILDON_APP(hildon_app_new());
        hildon_app_set_title(app, ("My Title"));

        osso_initialize("helloWorld", "0.1", TRUE, NULL);

        gtk_widget_show_all(GTK_WIDGET(app));
        gtk_main();

        return 0;
}

Thanks in advance
