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.

Because, of course, make hasn’t built anything.

Aargh!

Annoying, eh?
