New in Eclipse Mars: Launchbar

In “Going to Mars: Building a DIY Eclipse IDE for ARM Embedded Microcontrollers” I described how to install an Eclipse based IDE for ARM, based on Eclipse Mars (4.5) and CTD (8.7). There are many great new features in Eclipse Mars which makes that switch worthwhile: the Launchbar:

Launchbar in Eclipse Mars

A dream is are now a reality: a really, really easy way to build, run/debug an application!

Historically, launching (debugging or executing) a binary with Eclipse has been a pain: I need to open debug/launch configurations, it is hard to select the correct configuration, and so on. Until now, with Eclipse Mars and the Launchbar :-).

Installation

The Launchbar is not part of Mars C/C++. It needs to be installed from

Installing Launchbar

Installing Launchbar

Using Launchbar

The Launchbar has three buttons:

Launchbar

Launchbar

  1. Build the current project
  2. Launch the current project (debug or run)
  3. Stop the project launched

I can switch between running or debugging the project:

Run or Debug with Lauchbar

Run or Debug with Launchbar

I can easily select the configuration I want to use or create a new configuration:

Selecting Configuration

Selecting Configuration

To view or edit a configuration I can use the toolbar icon:

Edit or view configuration

Edit or view configuration

Finally, I could create a new connection:

Launchbar Connection

Launchbar Connection

‘Local’ is maybe a bit misleading: it will use the local GDB/debug connection. But it would be possible to use e.g. SSH to a remote board/client/etc.

Summary

That plugin is a big step forward in Eclipse to make build-debug-stop very easy. Building and debugging is one click away, without messing with debug and launch configurations. Yet another excellent reason to use Eclipse Mars πŸ™‚

Happy Launching πŸ™‚

  1. I just went to download Eclipse Mars and found that there is now Eclipse Neon. Do you know anything about this one yet? For instance, is it stable, and can your instructions for Eclipse Mars be “generally” applied to the Neon edition?

    Thanks. πŸ™‚

    • Mars has been released in June 2015, and the next release is Neon which is expected mid 2016.
      I have not tried Neon because it is not a release or stable release yet. But my instructions should apply to Neon too πŸ™‚

      • Thank you. I can wait for Neon then. I did not know how often the releases came.

        THANK YOU for all the help you have provided to many thousands of people worldwide with your blog over the years.

  2. I don’t get a “Run” selection in the drop-down menu – just Debug. I think I have to set up a “Run configuration” to make that show up, but I don’t know how to set this up. Is there a way to just have it program the flash and not launch a debugger?

  3. It took two tries, the first ended when I installed KSDK and close to the end Eclipse informed me the jar was corrupt. After removing KSDK, downloading a new copy and installing it I couldn’t get Eclipse to let me install it, it wanted to ‘fix’ something then would die.

    Created new folder and started over with a successful install up to installing the MCUonEclipse components, everything installed all right but when I restarted eclipse it hung at “Loading org.eclipse.compare” I installed the latest (was using Java 7) version of java, no help. I can get it to run with: eclipse -clean -refresh — that is the only way it will run.

      • I increased the HEAP space and Eclipse loads now but I’ve found other issues:

        java.lang.UnsatisfiedLinkError: C:\MCUEclipse\eclipse\plugins\com.pemicro.core_1.1.43.201511061812\pemicro_jloader.dll: Can’t load IA 32-bit .dll on a AMD 64-bit platform
        ~ this goes on so I snipped it short for this other error:

        com.freescale.processorexpert.core: PExCore: Invalid ID of the project component (fsl_lptmr_hal).
