Re: Questions I should have asked

Hi Alf,
I find that all one needs to develop for GTK on windows, is a decent
text editor and Cygwin.
1. Install Cygwin

2. Install GTK runtime and developer packages. I download these
from http://www.dropline.net/gtk/download.php . It seems that the maintainer
of these packages is no longer going to be updating these in the future.

3. Create hello.cpp:

#include <gtk/gtk.h>

int main(int argc,char *argv[])
{
  gtk_init(&argc, &argv);
  GtkWidget *window=gtk_window_new(GTK_WINDOW_TOPLEVEL);
  gtk_widget_show(window);
  gtk_main();
  return 0;
}

4. Create hello.o by compiling from the cygwin shell using:
gcc -c -Wall -mno-cygwin -mms-bitfields -O2 `pkg-config --cflags gtk+-2.0` 
hello.cpp -o hello.o

5. Link to create the exe:
g++ -Wall -mno-cygwin -mms-bitfields -s -mwindows  hello.o -o hello.exe 
`pkg-config --libs gtk+-2.0`

You should now have an executable windows application (that you will have 
to kill to shutdown).
You can run:
pkg-config --cflags gtk+-2.0
pkg-config --libs gtk+-2.0
from the command line to see what they do if you like?

Hopefully this will get you up and running.

Regards,
Clive
