Optional

On some Linux distributions you may need to run this command:

With Eclipse installed in the /opt directory, it can be accessed by any user.

Install OpenJDK-8:

You have completed installing the Eclipse IDE for C/C++ Developers and the OpenJDK.

Change directory to your home directory:

With your favorite text editor, create a text file named eclipse.desktop:

Copy the following to the text file:

[Desktop Entry]
Name=Eclipse
Type=Application
Exec=/opt/eclipse/eclipse
Terminal=false

Name[en]=Eclipse

Save the text file.

Set the text file eclipse.desktop to be executable:

Install eclipse.desktop:

Create a symbolic link in /usr/local/bin:

Add the Eclipse IDE icon to be displayed with the shortcut:

Start the Eclipse IDE:

Eclipse with ask you to select a directory for your workspace. Accept the default directory and click on the Launch button.

Eclipse will launch the workspace and display the welcome screen.

Start the process of creating a project by clicking on File > New > Project.

The New Project wizard will be displayed:

Select C/C++ Project. Click on the Next button.

The Templates for New C/C++ Projects will be displayed:

Select C++ Managed Build. Click on the Next button.

The C++ Project window will be displayed:

Enter a Project name of EgtProject. Under Project type, select Empty Project. Under Toolchains, select Cross GCC. Click on the Next button.

The Select Configurations window will be displayed:

By default, the Debug and Release configurations are selected. Click on the Next button.

The Cross GCC Command window will be displayed:

Enter the following information:

Cross compiler prefix: arm-buildroot-linux-gnueabi-
Cross compiler path: /home/<user>/buildroot-at91/output/host/bin

Click on the Finish button.

To add a new C++ source code file, hover over EgtProject, right-click and select New > Source File.

A New Source File window will open.

Enter basic.cpp in the Source file: box. Click on the Finish button.

The Eclipse IDE workspace now has the basic.cpp source file added to the project.

Enter the following source code to the basic.cpp window pane:

#include <egt/ui>
#include <iostream>
using namespace std;
using namespace egt;

int main(int argc, const char ** argv)
{
  Application app;
  TopWindow window;
  Button button(window, "Press Me");
  center(button);
  window.show();

  return app.run();
}

Save your program by selecting File > Save.

On the Host PC, using your favorite text editor, add the following to your ~/.bashrc file:

To set build properties, hover over EgtProject, right-click and select Properties from the menu at the bottom.

A Properties for EgtProject window will open:

In the left-hand pane of the Properties window select C/C++ Build > Tool Chain Editor.

Observe that the Current toolchain: dropdown box has Cross GCC selected.

Next, select C/C++ Build > Settings.

a

On the Tool Settings tab, select Cross Settings, observe the following fields contain the following:

Prefix: arm-buildroot-linux-gnueabi-
Path: /home/<user>/buildroot-at91/output/host/bin

​

Be sure to use the path to the location of where you have buildroot-at91 installed.

b

On the Tool Settings tab, select Cross G++ Compiler > Miscellaneous. Change the Other flags text box to the following:

-c -fmessage-length=0 `pkg-config libegt --cflags`

​

Ensure that the PKG_CONFIG_PATH points to the pkg-config tool located in the buildroot-at91 build.

​

Note the use of the back quote ( ` ). This performs command substitution so that the output of the pkg-config tool will be fed into the command line of the C++ compiler.

​

If a project contains C source files, the Cross GCC Compiler would require configuration. As the EgtProject only contains a C++ source file, this step is skipped.

c

On the Tool Settings tab, select Cross G++ Linker > Libraries. To the right of the Libraries pane, click on the Add… (a little green plus next to a file icon). Add the following library: pthread

d

On the Tool Settings tab, select Cross G++ Linker > Miscellaneous. Enter the following into the Linker flags text box:

`pkg-config libegt --libs`

​

This linker flag will pass the location of the libegt dependencies to the linker so that the pkg-config tool can fill in the libraries required to use libegt.

​

Ensure that the PKG_CONFIG_PATH points to the pkg-config tool located in the buildroot-at91 build.

​

Note the use of the back quote ( ` ). This performs command substitution so that the output of the pkg-config tool will be fed into the command line of the C++ compiler.

To build the project, hover over EgtProject, right-click and select Build Project from the menu. Or you can click on the Build icon.

The Console window (bottom pane) will display the build progress.

At the completion of a successful build, a Debug folder in the Project Explorer window in the left pane. Note the files in the folder: makefile, sources.mk, objects.mk and subdir.mk.

To set run properties, hover over EgtProject, right-click and select Run As > Run Configurations… from the menu.

In the left-hand pane, double-click on C/C++ Remote Application.

To setup a SSH connection with the target, click on the Connection New button.

A Create a new connection window will appear:

Select SSH from the dropdown box. Click on the OK button.

A New Connection window will appear:

Enter the following settings:

Connection name: Remote Host
Host: 10.0.0.20
User: root

Select Password based authentication
Password: <root_password>

Click on the Finish button.

In the Run Configurations window, enter the following in the Remote Absolute File Path for C/C++ Application: text box:

/root/basic

This is the location the basic.cpp executable will be loaded and run.

Click on the Run button.

Observe the WVGA Display on the target:

The basic.cpp executable is running remotely on the target.

To stop the program, press the Stop button (upper left hand, just below the menu bar).

To configure the Debug Configuration, hover over EgtProject, right-click and select Debug As > Debug Configurations… from the menu.

The Debug Configurations window will appear:

In the left pane, select EgtProject Debug.

From the Main tab, observe the settings that you entered in the previous section:

Connection: Remote Host
Remote Absolute File Path for C/C++ Applications: /root/basic

Select the Debugger tab.

Enter the path to the arm-based debugger:

GDB debugger: /home/<user>/buildroot-at91/output/host/bin/arm-linux-gdb

Create a GDB initialization script by creating a text file named gdbinit in your home directory: /home/<user>. Enter the following text:

handle SIGILL nostop 
set sysroot /home/<user>/buildroot-at91/output/host/arm-buildroot-linux-gnueabi/sysroot

Save the GDB initialization script.

On the Debug Configurations window, under the Debugger tab, enter the path to the GDB initialization script to:

GDB command file: /home/<user>/gdbinit

Click on the Apply button. Click on Close to close the Debug Configurations window.
