.. _ref-build-system:
The PyQt4 Build System
======================
.. versionadded:: 4.10
SIP v5 will not include an extensible build system, i.e it will not provide an
equivalent of SIP v4's :mod:`sipconfig` module. Consequently a version of PyQt
built with SIP v5 will not provide an equivalent of the
:mod:`~PyQt4.pyqtconfig` module. However there is still a need for certain
information to be shared between PyQt and other modules (such as QScintilla's
:mod:`~PyQt4.Qsci` module) that are built on top of it. Specifically it is
important that the same ``-t`` and ``-x`` command line flags are passed to the
``sip`` executable to create, for example, the QScintilla bindings as were
passed to create the PyQt bindings.
Starting with v4.10, :attr:`PyQt4.QtCore.PYQT_CONFIGURATION` is a dict that
describes how PyQt was configured. At the moment it contains a single value
called ``sip_flags`` which is a string containing the appropriate ``-t`` and
``-x`` flags.
The Old Build System
--------------------
.. deprecated:: 4.10
The old PyQt4 build system is an extension of the SIP v4 build system and is
implemented by the :mod:`~PyQt4.pyqtconfig` module. It can be used by
configuration scripts of other bindings that build on top of PyQt4 and takes
care of the details of the Qt installation.
Note that the :mod:`~PyQt4.pyqtconfig` module is only created if you use
:program:`configure.py` and not if you use :program:`configure-ng.py`.
.. module:: PyQt4.pyqtconfig
.. class:: Configuration(sub_cfg=None)
This class encapsulates configuration values that can be accessed as
instance objects. It is derived from :class:`sipconfig.Configuration`.
:param sub_cfg:
an optional list of sub-class configurations. It should only be used
by the ``__init__()`` method of a sub-class to append its own
dictionary of configuration values before passing the list to its
super-class.
.. attribute:: pyqt_bin_dir
The name of the directory where the PyQt4 utilities are installed.
.. attribute:: pyqt_config_args
The command line passed to :program:`configure.py` when PyQt4 was
configured.
.. attribute:: pyqt_mod_dir
The name of the directory where the :mod:`PyQt4` Python package is
installed.
.. attribute:: pyqt_modules
A space separated string of installed PyQt4 modules. The :mod:`Qt`
module is not included.
.. attribute:: pyqt_sip_dir
The name of the base directory where PyQt4's ``.sip`` files are
installed. Each module's ``.sip`` files are installed in a
sub-directory with the same name as the module.
.. attribute:: pyqt_sip_flags
A space separated string of the :program:`sip` command line options
used to build the PyQt4 modules. These should also be used when
building bindings that ``%Import`` any PyQt4 modules.
.. attribute:: pyqt_stubs_dir
.. versionadded:: 4.12
The name of the base directory where PyQt4's PEP 484 stub files are
installed.
.. attribute:: pyqt_version
The PyQt4 version as a 3 part hexadecimal number (e.g. v4.0.1 is
represented as ``0x040001``).
.. attribute:: pyqt_version_str
The PyQt4 version as a string. For development previews it will start
with ``preview-`` or ``snapshot-``.
.. attribute:: qt_data_dir
The value of ``QLibraryInfo::location(DataPath)`` for the Qt
installation.
.. attribute:: qt_archdata_dir
When building against Qt v5 this is the value of
``QLibraryInfo::location(ArchDataPath)``. When building against Qt v4
it is the value of ``QLibraryInfo::location(DataPath)``.
.. attribute:: qt_dir
The root directory of the Qt installation (normally the directory that
contains the :file:`bin` directory).
.. attribute:: qt_edition
The Qt edition.
.. attribute:: qt_framework
Set if Qt is built as a MacOS/X framework.
.. attribute:: qt_inc_dir
The value of ``QLibraryInfo::location(HeadersPath)`` for the Qt
installation.
.. attribute:: qt_lib_dir
The value of ``QLibraryInfo::location(LibrariesPath)`` for the Qt
installation.
.. attribute:: qt_threaded
Set if Qt is built with thread support (always set for PyQt4).
.. attribute:: qt_version
The Qt version as a 3 part hexadecimal number (e.g. v4.1.2 is
represented as ``0x040102``).
.. attribute:: qt_winconfig
Additional Windows specific configuration.
