Answer 1

Meh, the launch configuration - our biggest usability problem...

1. Go to Run -> Configure Launches
2. select your project to the left
3. hit the "+" button
4. to the right, select your project target
5. optionally add a build dependency (again, select e.g. your target).

that should be it.

/me really wants to rewrite this dialog...

After following the steps provided by milianw. In case it doesn't work, follow this steps:

1. Go to Run >> Current Launch Configuration
2. choose the current file name you are trying to compile.
