Turn On Line Numbers in Eclipse [Luna]

Personally, I’m not sure what any code editor thinks it is doing by not having line numbers switched on by default.

But, each to their own, so if you want to see your line numbers in Eclipse and you just can’t find out where on earth to turn them on, aaargh! Don’t panic.

Just go to:

Window -> Preferences -> General -> Editors -> Text Editors

And check the handy “Show line numbers” box:


Then, take a deep breath, and feel much better than you can now see which line of code you are editing at any given time.

It’s really easy to do and is a nice way to keep different types of projects together.

As you probably know, the default workspace is called ‘workspace’ and lives under your home folder on Linux. If you want to use additional workspaces, the steps below cover everything you need to know about using multiple workspaces:


1. Create a new folder

In your home directory, you need to create a new folder, which will be the location of your new workspace. You can call this folder anything: Coursework or 3DProjects, for example.

make: Nothing to be done for ‘all’ – Eclipse Error Solved

I’ve seen this odd error several times over the years, almost always after first importing a new project into Eclipse-CDT.

After import, when you try to build your project, it just returns the message make: Nothing to be done for all in the console.

And then, once you’ve got the error, nothing you do will kick your build into action – changing files, changing project settings, even deleting and recreating build configurations.

If you try to run the executable, you just get Launch failed. Binary not found.

Annoying, eh?
