Developing GTK+ applications

This recipe will show how to build, run, and debug a graphical GTK+ application using the Eclipse IDE.

Getting ready

1. Add the eclipse-debug feature to your project's conf/local.conf file as follows:

   EXTRA_IMAGE_FEATURES += "eclipse-debug"

2. Build a core-image-sato target image as follows:

   $ cd /opt/yocto/fsl-community-bsp/
   $ source setup-environment wandboard-quad
   $ bitbake core-image-sato
   

3. Build a core-image-sato toolchain as follows:

   $ bitbake -c populate_sdk core-image-sato
   

4. Install the toolchain as follows:

   $ cd tmp/deploy/sdk
   $ ./poky-glibc-x86_64-core-image-sato-cortexa9hf-vfp-neon- toolchain-1.7.1.sh
   

Before launching the Eclipse IDE, we can check whether we are able to build and launch a GTK application manually. We will build the following GTK+ hello world application:

The following is a code for gtk_hello_world.c:

#include <gtk/gtk.h>

int main(int argc, char *argv[])
{
  GtkWidget *window;
  gtk_init (&argc, &argv);
  window = gtk_window_new (GTK_WINDOW_TOPLEVEL...
