Im follwing this very good tutorial on how to create a test in box2D. I could run a stand project and have not had any problems so far. I right-clicked on the tests and clicked the "Add New Item" button. there I created FooTest.h and copied the code from the tutorial.
Unfortunately, I get an error message independent of the test, without giving the name of the class or structure. I looked at the sources of another .h file and can't see anything that shows that I need to include another file or do something else. I rebuilt the project several times.
My TestEntries file:
What did I do wrong? Should ive create FooTest.h differently?
