Netbeans 7.2 shows “Unable to resolve identifier” , although build is successful

Here’s an excerpt from my answer to another question.

Unresolved Identifier

If the source of the .cpp file looks like this

Click with the right mouse button on your project.
Check C/C++ Code As...
Run Reparse Project.

If that is not enough.
Go to Project Properties
Fill in the Include input field as described.

Set the include path correct.

I hope that can help you.
