Solving compilation problems
----------------------------

.. _suppress-warning:

suppress-warning
^^^^^^^^^^^^^^^^

The generator will generate several warnings which may be irrelevant to the
user. The ``suppress-warning`` node suppresses the specified warning, and it is
a child of the :ref:`typesystem` node.

.. code-block:: xml

    <typesystem>
        <suppress-warning text="..." />
    </typesystem>

The **text** attribute is the warning text to suppress, and may contain the *
wildcard (use "" to escape regular expression matching if the warning contain
a regular "*").

.. _extra-includes:

extra-includes
^^^^^^^^^^^^^^

The ``extra-includes`` node contains declarations of additional include files,
and it can be a child of the :ref:`namespace`, :ref:`value-type`,
:ref:`object-type` and :ref:`typesystem` and nodes.

The generator automatically tries to read the global header for each type but
sometimes it is required to include extra files in the generated C++ code to
make sure that the code compiles. These files must be listed using include
nodes within the extra-include node:

.. code-block:: xml

     <value-type>
         <extra-includes>
             <include file-name="..." location="global | local"/>
         </extra-includes>
     </value-type>

The **file-name** attribute is the file to include, such as "QStringList".
The **location** attribute is where the file is located: *global* means that
the file is located in $INCLUDEPATH and will be included using #include <...>,
*local* means that the file is in a local directory and will be included
using #include "...".

When specified as a child of the :ref:`typesystem` node, the include
directives are added to the module source file which contains
the type converter and registration code. It can be used to specify
additional includes required for the converter code snippets.

.. _include-element:

include
^^^^^^^

The ``include`` node specifies the name and location of a file that must be
included, and it is a child of the :ref:`namespace`, :ref:`value-type`,
:ref:`object-type` or :ref:`extra-includes` node.

The generator automatically tries to read the global header for each type. Use
the include node to override this behavior, providing an alternative file. The
include node can also be used to specify extra include files.

.. code-block:: xml

     <value-type>
         <include file-name="..."
             location="global | local"/>
     </value-type>

The **file-name** attribute is the file to include, such as "QStringList".
The **location** attribute is where the file is located: *global* means that
the file is located in $INCLUDEPATH and will be included using #include <...>,
*local* means that the file is in a local directory and will be included
using #include "...".
