This was a work in progress that was never finished.

This may be a better starting place.

YouTube Video

Here is a video that says it will show how to use Eclipse for remote debugging.

Here is where you get the RSE-runtime.

host$ sudo apt-get update
host$ sudo apt-get install eclipse
host$ sudo apt-get install gcc-4.4-arm-linux-gnueabi

Work in Progress

Eclipse is an open source Integrated Development Environment that's enjoying broad use.

Here's how to run gdb on Beagle via Eclipse

Installing on Host

Install Eclipse and the gdb tools

$ cd ~/oe
$ sudo  apt-get install eclipse 
$ source source-me.txt
$ bitbake gbd-cross

Install Remote System Tools

  • Start Eclipse ($ eclipse &)

Eclipse - Workspace Launcher.png

  • Click: OK

Eclipse - Welcome.png

  • Go to Help:Install New Software...

Eclipse - Install New Software.png

Eclipse - Add Site.png

  • Enter: Galileo in the Name field
  • Click: OK and wait while it fetches from the site.
  • Expand: Mobile and Device Development

Eclipse - Mobile Devices.png

  • Check: Eclipse C/C++ DSF gdb Debugger
  • Check: Eclipse C/C++ Remote Launch
  • Check: Remote System Explorer End-User Runtime
  • Check: Remote System Explorer User Actions
  • Expand: Programming Languages
  • Check: Eclipse C/C++ Development Tools
  • Click: Next >
  • Verify the list and Click Next >

Eclipse - Install Details.png

  • Accept the license and Click: Finish
  • Click: "Yes" to restart Eclipse
  • Click: "Yes" to use same workspace

Finding the Beagle's IP address

  • On the BeagleBoard run
$ ifconfig eth0

Note the IP address

  • On the host edit /etc/hosts and add:
137.112.41.76	Beagle (Use your IP address)
  • Exit the editor and try:
$ ping Beagle

If you don't get an answer something is messed up. Get help. On the host connect to the Beagle and create a workspace

$ ssh Beagle
$ mkdir -p workspace/HelloWorld/Debug

Creating a New Project and Setting up for Remote Debugging

Now back to the Eclipse

  • Click: File:New:C Project

Eclipse - New C Project.png

  • Name the project HelloWorld

Eclipse - C Project.png

  • Click: Finish
  • Click: Project:Properties

Eclipse - Project Properties.png

  • Expand: C/C++ Build
  • Select: Settings
  • Tab: Tool Settings
  • Select: GCC C Compiler
  • Replace "gcc" in "Command:" with "~/oe/angstrom-dev/cross/armv7a/bin/arm-angstrom-linux-gnueabi-gcc"

Eclipse - gcc.png

  • Click: Directories (below GCC C Compiler
  • Click Eclipse - Add.png (Add...) button and insert "/home/yoder/oe/angstrom-dev/staging/armv7a-angstrom-linux-gnueabi/user/include" (Replace yoder with your path name.)
  • Click: GCC C Linker (below Directories)
  • Replace "gcc" in "Command:" with "~/oe/angstrom-dev/cross/armv7a/bin/arm-angstrom-linux-gnueabi-gcc"
  • Click: Libraries
  • Click: Add... to Library search path (-L) (the bottom one) insert "~/oe/angstrom-dev/staging/armv7a-angstrom-linux-gnueabi/lib"
  • Click OK to close Properties for HelloWorld window

Creating and Compiling a New C File

  • Copy the HelloWorld file that we have been using into ~/workspace/HellowWorld.
  • Click File:Refresh. You file should appear in the project.

  • Hit Ctrl-B to build, or click the little hammer Eclipse - Build Button.png.

Running Your Program

  • Menu: Run:Debug Configurations...

Eclipse - Debug Config.png

  • Double-Click C/C++ Remote Applcation to create a new configuration
  • Name it BeagleBoard
  • Project: Click Browse and select HelloWorld
  • C/C++ Application: Click Search Project and select HelloWorld
  • Remote Absolute File Path... Click: Browse...
  • Connection: Click New...

Eclipse - Select Remote.png

  • Select: SSH Only and Click Next >
  • Host name: Beagle
  • Click: Finish
  • "Select Remote C/C++" will appear. Connection: Beagle

Eclipse - Select Remote 001.png

  • Expand: My Home, workspace, HelloWorld, Debug

Eclipse - Select Remote 002.png

  • Click: OK
  • In the Properties window select Connection: Beagle
  • Click: Apply
  • Tab: Debugger
  • GDB debugger: Click: Browse and look for "~/oe/tmp/cross/armv7a/bin/arm-angstrom-linux/gnueabi-gdb"

Eclipse - Debugger.png

  • In Debugger Options Tab: Shared Libraries
  • Add... "~/oe/angstrom-dev/staging/armv7a-angstgrom-linux-gnueabi/lib"
  • Click: Debug (bottom right)

It should compile your file (if needed), copy it to the Beagle and start gdb on it. However I haven't been able to make it work.

Fix: The first time you try to select the Remote Absolute File Path for C/C++ Application you haven't uploaded the binary file to the Beagle. Hence you cannot select it via the dialogue. Once you clicked the "Debug" button you can re-open the dialogue and select the binary or you can manually complete the line to "/home/MyUsername/workspace/HelloWorld/Debug/HelloWorld".

Back when I had this working, it will run up to main() and wait for your input. Try the single step button (F6 step over, F5 step into)

Be sure to hit Terminate (Ctrl-F2) when done.

Add a for loop and watch the index variable change!

This is taken from: http://www.ibm.com/developerworks/opensource/library/os-eclipse-stlcdt/index.html

You might be able to do this via apt-get install. I used the add/remove program app in Red Hat and selected Fedora Eclipse. It appears to load lots of things. This load version 3.4.1

In Ubuntu go to Applications: Add/Remove Select Show: All available applications Search: eclipse Check: Eclipse Click: Apply Changes Wait for some 113 files to download (15 minutes on a fast connection) With this install you need to load a few more things. Go to Help:Software Updates:Find and Install... Select: Search for new features to install Select: Callisto Discovery Site Click: Finish (wait a moment) Select a site near you (wait a moment) Expand: Callisto Discovery Site Select: C and C++ Development Next, Accept, Next, Finish (wait)

This loads version 3.2.2


        1. Install the c/c++ stuff

Select: Help:Software Updates Tab: Available Software Expand: Ganymede Update Site Check: C and C++ Development Click: Install Expand: Remote Access and Device Developement Check: Remote System Explorer C/C++ Remote Debugger Launcher Check: Remote System Explorer End-User Runtime Click: Install Click: Next Click: I accept... Click: Finish

          1. Fedora #####

I did see the Canymede Update Site on Fedora, so I Select: Help:Software Updates Tab: Available Software Click: Add Site Location: http://download.eclipse.org/releases/ganymede Click: OK The Available Software list should update nad "Ganymede Update Site" should appear. The follow the instructions above.

          1. #####

Start Eclipse Select: File:New:Project... Expand: C Select: C Project Click: Next Project Name: HelloWorld (no spaces) Select: Hello World ANSI C Project Click: Next Fill in to suit, Click: Next Click: Finish Tab: C/C++ Projects Expand: HelloWorld Expand: src Expand: HelloWorld.c Double-Click: main(void) The file will open in a window

This will create an executable that runs on the Ubuntu Linux (guest) platform.

          1. Beagle Execution

Here's how to run it remotely on the Beagle. This is from: http://www.nabble.com/Solution:-Using-Eclipse-CDT-for-Gusmtix-development-td18251552.html Here's what I did differently: 4) Project Properties/Settings

* On "GCC C++ Compiler" change "Command" to 

"~/gumstix/gumstix-oe/tmp/cross/bin/arm-angstrom-linux-gnueabi-g++" (dbg_03.png)

* On "GCC C++ Compiler/Directories" add 

"~/gumstix/gumstix-oe/tmp/staging/arm-angstrom-linux-gnueabi/include" to "Includes paths (-I)"

I used: tmp/staging/arm-angstrom-linux-gnueabi/usr/include

* On "GCC C++ Compiler/Miscellaneous" add "-c -march=armv5te 

-mtune=xscale -Wa,-mcpu=xscale" to "Other flags"

I didn't change this since the gcc should have all this set.

5) On "Run/Debug Configurations" add "C++ Remote Application"

* On "Main" tab

This is in Run:Debug Configurations


In eclipse, Select: Window:Open Perspective:C/C++ Click on the HelloWorld project to select it Select: Project:Properties Expand: C/C++ Build Select: Discovery Options


Starting point: http://www.nabble.com/Solution:-Using-Eclipse-CDT-for-Gusmtix-development-td18251552.html

On the Beagle: opkg install openssh openssh-sftp openssh-server opkg install gdbserver

In Eclipse File:New Project Select General:Project I used project name "Remove gdb"
