Configuring PyQt4¶

Dec 03, 2020 On Windows, click the Change button under the Destination Folder heading, and select where you want to install. On Mac, click the Change Install Location button in the lower-right corner of the window, and select a folder directory. The iTunes player keeps all your music, movies, and TV shows in one place. Quickly organize and browse your media library, transfer to any of your devices, and play your music how you like. Use iTunes to rip your music CDs and have them automatically organized into albums and titles, even see the album cover right there on your computer.

After unpacking the source package (either a .tar.gz or a .zip filedepending on your platform) you should then check for any README filesthat relate to your platform.

If you are using the commercial version of PyQt4 then you must copy yourlicense file to the sip directory, or to the directory specified by the--license-dir option of configure-ng.py.

You need to make sure your environment variables are set properly for yourdevelopment environment.

In order to configure the build of PyQt4 you need to run either theconfigure-ng.py or the configure.py Directx 11 web installer windows 10. script.

configure.py is the original configuration script that uses thebuild system of SIP v4 (i.e. the sip.sipconfig module). It will besupported for the life of PyQt4.

configure-ng.py is the new configuration script that uses Qt’sqmake program to do all the heavy lifting. It has the followingadvantages:

it supports cross-compilation
it is the basis of PyQt5’s configuration script
generated Makefiles have an uninstall target
it will work with SIP v5 (which will have no build system).

Users are encouraged to switch to using configure-ng.py in order toease the future transition to SIP v5 and/or PyQt5.

Using configure-ng.py¶

The configure-ng.py script is used to configure PyQt4 as follows:

This assumes that the Python interpreter is on your path. Something like thefollowing may be appropriate on Windows:

If you have multiple versions of Python installed then make sure you use theinterpreter for which you wish to build PyQt4 for.

The full set of command line options is:

--assume-shared¶

Normally Qt is checked to see if it has been built as shared libraries.Some Linux distributions configure their Qt builds to make this checkunreliable. This option ignores the result of the check and assumes thatQt has been built as shared libraries.

--bindir <DIR>, -b <DIR>¶

The pyuic4, pyrcc4 and pylupdate4utilities will be installed in the directory <DIR>.

--concatenate, -c¶

The C++ source files for a Python module will be concatenated. Thisresults in significantly reduced compilation times. Most, but not all,C++ compilers can handle the large files that result. See also the--concatenate-split option.

--concatenate-split <N>, -j <N>¶

If the --concatenate option is used to concatenate the C++ sourcefiles then this option determines how many files are created. The defaultis 1.

--configuration <FILE>¶

<FILE> contains the configuration of the PyQt4 build to be used insteadof dynamically introspecting the system and is typically used whencross-compiling. See Configuring with Configuration Files.

--confirm-license¶

Using this confirms that you accept the terms of the PyQt4 license.

--dbus <DIR>, -s <DIR>¶

The dbus-python.h header file of the dbus-python package can befound in the directory <DIR>/dbus.

--debug, -u¶

The PyQt4 modules will be built with debugging symbols. On Windows thisrequires that a debug version of Python is installed.

--designer-plugindir <DIR>¶

The Python plugin for Qt Designer will be installed in the directory<DIR>.

--destdir <DIR>, -d <DIR>¶

The PyQt4 Python package will be installed in the directory <DIR>. Thedefault is the Python installation’s site-packages directory. Ifyou use this option then the PYTHONPATH environment variable mustinclude <DIR>.

--enable <MODULE>, -e <MODULE>¶

Normally all PyQt4 modules are enabled and are built if the correspondingQt library can be found. Using this option only those modules specificallyenabled will be checked for and built. The option may be specified anynumber of times.

--help, -h¶

Display a help message.

--license-dir <DIR>¶

The license files needed by the commercial version of PyQt4 can be found inthe directory <DIR>.

--no-deprecated¶

All Qt v4 features that have been deprecated in Qt v5 will be disabled.This is useful when porting PyQt4 applications to PyQt5.

--no-designer-plugin¶

The Qt Designer plugin will not be built.

--no-docstrings¶

The PyQt4 modules will not contain automatically generated docstrings.

--no-python-dbus¶

The Qt support for the standard Python DBus bindings is disabled.

--no-qsci-api¶

The PyQt4.api QScintilla API file is not installed even ifQScintilla does appear to be installed.

--no-sip-files¶

The .sip files for the PyQt4 modules will not be installed.

--no-tools¶

New in version 4.11.

The pyuic4, pyrcc4 and pylupdate4 tools will not be built.

--no-timestamp, -T¶

Normally the header comments of each generated C/C++ source file includesa timestamp corresponding to when the file was generated. This optionsuppresses the inclusion of the timestamp.

--plugin <PLUGIN>, -t <PLUGIN>¶

If Qt has been built as static libraries then the static plugin<PLUGIN> will be linked with the appropriate PyQt4 module. The optionmay be specified any number of times.

--protected-is-public¶

On certain platforms the size of PyQt4 modules can be significantly reducedby redefining the C++ protected keyword as public duringcompilation. This option enables this behaviour and is the default onLinux and MacOS/X.

--protected-not-public¶

The default redefinition of protected to public during compilationon Linux and MacOS/X is disabled.

--pyuic4-interpreter <FILE>¶

<FILE> is the name of the Python interpreter used in the pyuic4wrapper. The default is platform dependent.

--qmake <FILE>, -q <FILE>¶

Qt’s qmake program is used to determine how your Qt installationis laid out. Normally qmake is found on your PATH.This option can be used to specify a particular instance ofqmake to use. This option is not available on Windows whereqmake must be on PATH.

--qsci-api, -a¶
