Hi Phil. Thanks for answering so quickly.

Here is my experience doing the same from a ``cmd.exe`` (still not working).

  First, note that my PATH does NOT contain Cygwin::

    C:\tmp\PyQt-win-gpl-4-snapshot-20070710>echo %PATH%
    C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;c:\Program
Files\Microsoft SQL
Server\90\Tools\binn\;c:\Python25\Lib\site-packages\mingw-3.4.5-win32.egg\bin;C:\blp\API

  I ran the simplest configure command::

    C:\tmp\PyQt-win-gpl-4-snapshot-20070710>C:/Python25/python.exe configure.py
    Determining the layout of your Qt installation...
    Error: Make sure you have a working Qt v4 qmake on your PATH or use the -q
    argument to explicitly specify a working Qt v4 qmake.

  Oops, it seems I need to specify the location of qmake. Okie, so I
  add it to the cmdline::

    C:\tmp\PyQt-win-gpl-4-snapshot-20070710>C:/Python25/python.exe
configure.py -q C:/Qt/4.3.0/qmake/qmake.exe -w
    Determining the layout of your Qt installation...
    C:\Qt\4.3.0\qmake\qmake.exe -o qtdirs.mk qtdirs.pro
    QMAKESPEC has not been set, so configuration cannot be deduced.
    Error processing project file: qtdirs.pro
    Error: C:\Qt\4.3.0\qmake\qmake.exe failed to create a makefile.
Make sure you
    have a working Qt v4 qmake on your PATH or use the -q argument to explicitly
    specify a working Qt v4 qmake.

  Oh, oh; I need to set QMAKESPEC, okay::

    C:\tmp\PyQt-win-gpl-4-snapshot-20070710>set QMAKESPEC=win32-g++

  Still does not work::

    C:\tmp\PyQt-win-gpl-4-snapshot-20070710>C:/Python25/python.exe
configure.py -q C:/Qt/4.3.0/qmake/qmake.exe -w
    Determining the layout of your Qt installation...
    C:\Qt\4.3.0\qmake\qmake.exe -o qtdirs.mk qtdirs.pro
    Could not find mkspecs for your QMAKESPEC(win32-g++) after trying:
            C:/iwmake/build_mingw_opensource\mkspecs
    Error processing project file: qtdirs.pro
    Error: C:\Qt\4.3.0\qmake\qmake.exe failed to create a makefile.
Make sure you
    have a working Qt v4 qmake on your PATH or use the -q argument to explicitly
    specify a working Qt v4 qmake.

  It's that problem with setting the difficult-to-find QMAKEPATH (see
  ``C:/iwmake/build_mingw_opensource\mkspecs``); I've already been
  through this, so I set it::

    C:\tmp\PyQt-win-gpl-4-snapshot-20070710>set QMAKEPATH=C:/Qt/4.3.0

  But it still won't go through::

    C:\tmp\PyQt-win-gpl-4-snapshot-20070710>C:/Python25/python.exe
configure.py -q C:/Qt/4.3.0/qmake/qmake.exe -w
    Determining the layout of your Qt installation...
    C:\Qt\4.3.0\qmake\qmake.exe -o qtdirs.mk qtdirs.pro
    mingw32-make -f qtdirs.mk release
    'mingw32-make' is not recognized as an internal or external command,
    operable program or batch file.
    Error: Failed to create release\qtdirs.exe. Make sure you have a

    qmake on your PATH or use the -q argument to explicitly specify a

    qmake.

  I need to adjust my PATH to access MinGW's make::

    C:\tmp\PyQt-win-gpl-4-snapshot-20070710>set PATH=C:\MinGW\bin;%PATH%

    C:\tmp\PyQt-win-gpl-4-snapshot-20070710>echo %PATH%
    C:\MinGW\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;c:\Program
Files\Microsoft SQL
Server\90\Tools\binn\;c:\Python25\Lib\site-packages\mingw-3.4.5-win32.egg\bin;C:\blp\API

  But it still does not go through::

    C:\tmp\PyQt-win-gpl-4-snapshot-20070710>C:/Python25/python.exe
configure.py -q C:/Qt/4.3.0/qmake/qmake.exe -w

Am I missing something, or it seems that this
``c:\iwmake\build_mingw_opensource`` path is still in effect. How do I
fix that?
