Question

I am on with trying to compile a simple GTK+ Hello World app on windows. I am following a tutorial from this url:

http://pandhare0.tripod.com/#mini-Tutorial

The contents of my HelloWorld.c is as follows and also taken from a wikipedia example:

 #include <gtk/gtk.h>

 int main (int argc, char *argv[])
 {
    GtkWidget *window;
    GtkWidget *label;

    gtk_init (&argc, &argv);

    /* create the main, top level, window */
    window = gtk_window_new (GTK_WINDOW_TOPLEVEL);

    /* give it the title */
    gtk_window_set_title (GTK_WINDOW (window), "Hello World");

    /* Connect the destroy signal of the window to gtk_main_quit
     * When the window is about to be destroyed we get a notification and
     * stop the main GTK+ loop
     */
    g_signal_connect (window, "destroy", G_CALLBACK (gtk_main_quit), NULL);

    /* Create the "Hello, World" label  */
    label = gtk_label_new ("Hello, World");

    /* and insert it into the main window  */
    gtk_container_add (GTK_CONTAINER (window), label);

    /* make sure that everything, window and label, are visible */
    gtk_widget_show_all (window);

    /* start the main loop, and let it rest there until the application is closed */
    gtk_main ();

    return 0;
 }

I have followed the instructions to generate the build bat file and the contents of which are below:

path C:\MinGW\bin;C:C:\gtk_2_22_x64\lib\%path%

I have the MinGW inside my environment path. When I run the following command inside my command prompt:

gtkcmd.bat HelloWorld.c HelloWorld.exe

I get the following output:

C:\gtk+_compilation>gtkcmd.bat HelloWorld.c HelloWorld.exe

Previously I had tried, strictly what the tutorial said, and used the / in the path statements as opposed to the full paths I now use. When I did use the / though it could not link anything. Every GTK statement returned an undefined error. So I have stayed with using the Full path in the header and linkers statements in the command line. As you can see from the above, it cannot find the gtk/gth.h header. This confuses me as I can clearly see the paths for such inside the command line arguments.

Any help is greatly appreciated.

Cheers,

Andrew

UPDATE:

Ok – I did screw up the bat file – daft mistakes but after correcting these inline with an answer below I now have the following bat file:

path \MinGW\bin;C:\gtk_2_22_x64\lib\%path%

After this I now get the following errors from the compilation:

It seems you folowed the instructions to create the .bat file incorrectly somehow – this:

-IC:C:\gtk_2_22_x64\include\gtk-2.0

should be:

-IC:\gtk_2_22_x64\include\gtk-2.0

and similar elsewhere. It looks like your path has got set up incorrectly – this:

path C:\MinGW\bin;C:C:\gtk_2_22_x64\lib\%path%

should be:

path C:\MinGW\bin;C:\gtk_2_22_x64\lib\%path%

or something like it (note C:C: should be C:).

Edit: And now your problem is that the linker cannot find the libraries. The batch file should contain stuff like:

-L/path/to/gtk/libraries

but I don’t know how you specify that when you create the file.
