how to resolve this one anyone can explain ,make: *** No rule to make target 'all'
Are you actually seeing any errors in the build log in the Console view?
If not, you might just need to delete this message (in the problems View, I assume) - as it might just be left over from a previous build that did fail.
You could also do a clean followed by a normal build by pressing the appropriate buttons in the Quickstart Panel.
