Create an empty .c file with your favorite text editor or any console text editor. Write a printf function, as follows, and compile it:

$ nano hello_world.c
#include <stdio.h>
int main (void){
  printf("Hello World\n");
  return 0;
}
$ $CC hello_world.c –o helloworld

You can copy the binary file on to the Intel Galileo development board with the scp command. SSH and SCP tools are installed with the full image we built to boot with the SD card.

If the board is connected to your local network, you can easily transfer files with the scp command to the board from your host machine. Secure Copy Protocol (SCP) securely transfers computer files between a local host and a remote host. Therefore you can transfer files from Intel Galileo to your development PC or from your PC to the Intel Galileo board.

$ scp helloworld [email protected]:/home/root/apps

$ ssh [email protected]

Open the Intel Galileo board's terminal and run the application from the folder you copied in the binary file:

$ cd /home/root/apps
$ ./helloworld
Hello World

To install new software on the Eclipse IDE, from the menu bar, go to Help | Install New Software.

This will prompt you with a window to start the installation.

First, you need to select the download site for the plugins. On the host I use, Eclipse Kepler (the previous version is Juno) is installed so, from the Work With drop-down list, select the correct site.

Click on http://download.eclipse.org/releases/kepler.

This action will load the available plugins to the following list.

Select the required plugins to be installed. Perform the following steps to select plugins from the available software:

Expand Linux Tools and select LTTng – Linux Tracing Toolkit.

Expand Mobile and Device Development and select the following items from the list:

Expand Programming Languages and select C/C++ Autotools support and C/C++ Development Tools.

Open the Install New Software Window again.

This time you should add the link for the Yocto Project plugin. Click on the Add button, which will open a smaller window. Enter a meaningful name (for example, Yocto ADT Plugin), enter http://downloads.yoctoproject.org/releases/eclipse-plugin/1.6/kepler, and click on Add.

When you add and select the new link from the Work with: menu, it will refresh the list of available packages to be installed.

Check the Yocto Project ADT Plug-in, Yocto Project Bitbake Commander Plug-in, and Yocto Project Documentation plug-in boxes.

Click on the Next > button, read and accept the license agreements, and finish the installation as shown in the following screenshot:

Click on Window from the Eclipse IDE menu and select Preferences from the list.

A new window will appear; from the list that appears on the left-hand side of the window, select Yocto Project ADT.

You need to enter the paths where you installed the toolchain, as shown in the following screenshot:

Click on Apply; if the Yocto Project plugin doesn't complain about anything, the configuration should work.

First, we will open Remote System Explorer in the Eclipse IDE.

Click on Window in the Eclipse IDE menu, hover over Open Perspective if Remote System Explorer is on the list. Click on it if it is not; then, click on Other and select Remote System Explorer in the opened window.

In the new perspective, define a new connection by clicking on the button where Remote Systems are listed or right-click to add a new connection.

This will open a new window called Select Remote System Type; select Linux and click on Next.

This will show you a window, as shown in following screenshot, where you need to type in the Intel Galileo development board's IP address and a description for the connection:

Select SSH Types in the following window when processing .ssh files, processes.shell.linux, ssh.shells, and ssh.terminals.

This process defines a remote connection. Now we need to configure Eclipse in order to run applications on a remote device, as follows:

In the Eclipse menu, click on Run and select Run Configurations. When the new window appears, click on the icon with a plus sign on it in order to create a new configuration.

You need to fill the spaces according to your host system's configuration. Select the remote connection and remote path to deploy the application.

If you save this instance, you can use it later for any other project you create on Eclipse to run on Intel Galileo.

Click on File from the Eclipse IDE menu, select New, and then click on C Project. This will open a new window, as shown in the following screenshot.

Expand Yocto Project ADT Autotools Project and select Hello World ANSI C Autotools Project:

After you finish this, all the related files will be created. You can just build the Hello World sample by clicking on Build and running with the selection Run As, Remote Application on Intel Galileo.
