error : A 'DarcyPressure' is not a registered object.

[ziyiwang141319]

*** ERROR ***
A 'DarcyPressure' is not a registered object.

If you are trying to find this object in a dynamically loaded library, make sure that
the library can be found either in your "Problem/library_path" parameter or in the
MOOSE_LIBRARY_PATH environment variable.

I tried to create objects as problem and kernel, but always got this "not a registered object". So I copied DarcyPressure example in the tutorial, still got the same error. I created the head file(.h) and source file(.cpp) for DarcyPressure, and only changed the lineregisterMooseObject("capybaraApp", DarcyPressure); where capybara is my app name. I am using a mac system and I did make process before running inputfile. I put the head file in include folder, and put source file in folder under src/kernels/.
Could you please help me with this?

Hello

How is capybaraapp spelled in the base/ ... app.C file?

Any mismatch, caps included, between the registering and the name of the app will get you this error

Then how to do it

[GiudGiud]

That s your default text editor

Probably vi or emacs

I don't know what to do next. I've never uploaded anything to github

[GiudGiud]

This does not upload it just saves your work

There are good help pages for using git
