问题
I have a problem with using Sphinx-doc's Ref function, i put a label above a paragraph and then i try to link to that label from another doc but inside the same project.
The label i use in one document:
.. _hal_1k_1p:
And the Ref i try to use to link to that label:
:ref:`Link title hal_1k_1p`
But i only get this error message when building the doc:
WARNING: undefined label: link title hal_1k_1p (if the link has no caption the label must precede a section header)
What am i doing wrong?

Okay, looking at :ref: you need to have this:
:ref:`Link title <ha1_1k_1p>`
to link to that label.
Ensure you have angle brackets surrounding your label like so: <label>
