Download: PyQt 4.8.3 x86 (compiled against Qt 4.7.1) for Maya 2012

x64: Nathan Horne compiled a version, available on his website

In case you want to build it yourself, here’s the guide (based on Ozgur Yilmaz’s guide): The final build will include everything that you’ll find in the default PyQt installer.

Pre-requisites:

• sip source (e.g. 4.12.1)
• qscintilla2 source (e.g. 2.5.1)
• pyqt4 source (e.g. 4.8.3)
• Nullsoft installer maker
• MySQL Community Server 5.x (download the version that has -win32 in its name)
• OpenSSL (e.g. 1.0.0d)
• Qt 4.7.1 pre-compiled LGPL libraries (except you want to compile the libraries yourself)
• (get the Qt SDK if you don’t want to use the pre-compiled libraries and compile them yourself instead)
• Python 2.6
• Perl (OpenSSL needs this to compile)
• MS Visual C++ Express 2008

Unpack everything except Perl and Python into the directory c:\qt. Put Python in c:\python26 for convenience. Perl can be installed anywhere. Make sure python.exe and perl.exe are in the PATH.

Compiling:

Open up the Visual Studio 2008 x86 Command Prompt from start menu/programs/etc. First we need to set some additional environment variables:

• set PATH=c:\qt\4.7.1\bin;%PATH%

• set LIB=c:\qt\4.7.1\lib;%LIB%

• set INCLUDE=c:\qt\4.7.1\include;%INCLUDE%

• set QMAKESPEC=c:\qt\4.7.1\mkspecs\win32-msvc2008

• set QTDIR=c:\qt\4.7.1\qt

Compile SIP:

• cd sip-4.12.1

• python configure.py -p win32-msvc2008

• nmake

• nmake install

Compile PyQt4:

• cd PyQt-win-gpl-4.8.3

• python configure.py -w (answer yes to the question)

• nmake

• nmake install

Compile QScintilla:

• cd QScintilla-gpl-2.5.1\Qt4

• qmake qscintilla.pro

• nmake

• nmake install

• cd ..\Python

• python configure.py

• nmake

• nmake install

• cd ..\designer-Qt4

• qmake designer.pro

• nmake

• nmake install

Compile PyQt4 mySQL driver:

• set LIB=c:\qt\mysql-5.5.11-win32\lib;%LIB%

• set INCLUDE=c:\qt\mysql-5.5.11-win32\include;%INCLUDE%

• cd 4.7.1

• cd src\plugins\sqldrivers\mysql

• qmake mysql.pro

• nmake

• nmake install

Building Qt Translations:

• cd 4.7.1

• cd translations

• qmake translations.pro

• nmake

Compile OpenSSL: (make sure perl.exe is in your path!)

• cd openssl-1.0.0d

• perl Configure VC-WIN32 no-asm --prefix=c:/openssl

• ms\do_ms

• nmake -f ms\ntdll.mak

• nmake -f ms\ntdll.mak install

Creating the installer exe:

In the PyQt folder open PyQt.nsi in a text editor and make the following changes:

• !define PYQT_PYTHON_MAJOR   "2"

• !define PYQT_PYTHON_MINOR   "6"

• !define PYQT_ARCH           "x86"

• !define MYSQL_SRC_DIR       "C:\Qt\mysql-5.5.11-win32"

Now do some file copying…

• In the mysql folder copy all the dll files from the lib folder to the bin folder.
• Copy the sip folder from c:\qt\pyqt-win-gpl-4.8.3 to c:\python26\lib\site-packages\pyqt4.
• Copy sip.exe from c:\Qt\sip-4.12.1\sipgen to c:\python26\lib\site-packages\pyqt4\bin.
• Copy sip.h from c:\Qt\sip-4.12.1\sipgen to c:\python26\lib\site-packages\pyqt4\include.
• the Qt dlls will be copied automatically by the installer

In the explorer right click the nsi file and chose “Compile NSIS Script”.

If all goes well then a installer named PyQt-Py2.6-x86-gpl-4.8.3-1.exe should be created.

Pfew – finally DONE!
