This document contains instructions on building PyQt under Windows, using the pre-built binary version of Qt installed via its installer.

:Source: http://www.diotavelli.net/PyQtWiki/BuildPyQt4Windows

Typically, you want to built the PyQt snapshots when it is lagging a little bit behind the Qt release. When I wrote this document, I wanted to build PyQt for Qt-4.3.3 and there was no binary at that time.

See this thread for more details: http://www.mail-archive.com/pyqt%40riverbankcomputing.com/index.html#11081

Note: follow these instructions to-the-letter. This is Windows. Any slight variation might throw you off.

This document is up-to-date for the following versions:

• Qt-4.3.3
• Python-2.5
• MinGW-5.1.3
• SIP snapshot as of 2007-07-11
• PyQt4 snapshot as of 2007-07-11

• Grab the binary installer (.exe) for the latest Qt release on TrollTechs webpage.

• Execute the installation, with or without MinGW depending on if you already have it.

This will place Qt in C:\Qt\<version> by default.

• Download the Python MSI binary from the python.org website and run it, and install it (typically in C:\Python25\python.exe).

• Add the Python25\ folder to your path

You will need an install of MinGW that contains mingw32-make.exe. Install MinGW using the binaries from the MinGW website. I placed mine in C:\MinGW.

• Make sure you have::

  C:\MinGW\bin/mingw32-make.exe C:\MinGW\bin/g++.exe

You MUST use the cmd.exe shell, and not Cygwin's bash nor MinGW nor MKS not anything else.

Start cmd.exe and set your PATH to something clean that contains both MinGW and Qt::

set PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\Qt\4.3.3\bin;C:\MinGW\bin

Verify your PATH configuration by running these two commands::

g++ -v qmake -v

• Download and unpack the SIP snapshot source for Windows.

• Configure it, making sure to use the -p option (otherwise the build runs in an infinite loop)::

  C:\tmp\sip-snapshot-20070704> C:/Python25/python configure.py -p win32-g++ C:\tmp\sip-snapshot-20070704> mingw32-make C:\tmp\sip-snapshot-20070704> mingw32-make install

This should install the following files in your Python library::

C:\Python25\include\sip.h C:\Python25\Lib\site-packages\sip.pyd C:\Python25\Lib\site-packages\sipconfig.py C:\Python25\Lib\site-packages\sipconfig.pyc C:\Python25\Lib\site-packages\sipdistutils.py C:\Python25\sip.exe

Using the same shell setup as above,

• Your path should look something like this: C:\Qt\bin;C:\MinGW\bin;C:\Python25;C:\MinGW\libexec\gcc\mingw32\3.4.2

*** Note: MinGW must be inside C:\MinGW, it doesn't work if you move it ***

• Download and unpack the PyQt4 snapshot source for Windows.

• Configure it::

  C:\tmp\PyQt-win-gpl-4-snapshot-20070710> C:/Python25/python configure.py -w Determining the layout of your Qt installation... C:\Qt\4.3.3\bin\qmake.exe -o qtdirs.mk qtdirs.pro mingw32-make -f qtdirs.mk release mingw32-make -f qtdirs.mk.Release mingw32-make[1]: Entering directory C:/tmp/PyQt-win-gpl-4-snapshot-20070710' g++ -c -O2 -frtti -fexceptions -mthreads -Wall -DUNICODE [...] g++ -enable-stdcall-fixup -Wl,-enable-auto-import [...] lqtmain -lQtCore4 mingw32-make[1]: Leaving directory C:/tmp/PyQt-win-gpl-4-snapshot-20070710' release\qtdirs.exe This is the GPL version of PyQt 4-snapshot-20070710 (licensed under the GNU General Public License) for Python 2.5 on win32.

  Type 'L' to view the license. Type 'yes' to accept the terms of the license. Type 'no' to decline the terms of the license.

  Do you accept the terms of the license? yes Checking to see if the QtGui module should be built... g++ -DUNICODE -DQT_LARGEFILE_SUPPORT -DQT_DLL -DQT_NO_DEBUG -DQT_GUI_LIB -I. -IC:\Qt\4.3.3\mkspecs\default [...] [...]

  This should complete succesfully.

  Note: you should not have to set any variable. QTDIR is now obsolete. QMAKESPEC should be found automatically, but if it is not, you can probably safely use the -p win32-g++ option.

• Compile it::

  C:\tmp\PyQt-win-gpl-4-snapshot-20070710> mingw32-make

• Install it::

  C:\tmp\PyQt-win-gpl-4-snapshot-20070710> mingw32-make install

This should install the following files::
