What's the recommended compiler to use to compile Qt and PyQt on Windows?
The free edition of Qt-4.5.2 builds very cleanly with mingw. I did a
static build of Qt with mingw (gcc 3.4.5) on Windows XP.
I downloaded the Python 2.6.2 binary from the Python website and built
the
latest sip snapshot using the win32-g++ platform. That appears to build
okay.
I then tried the latest PyQt snapshot but it failed:
g++ -c -O2 -frtti -fexceptions -mthreads -Wall -DUNICODE
-DQT_LARGEFILE_SUPPORT -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB
-DQT_THREAD_SUPPORT -I"..\..\..\..\Qt\4.5.2\include\QtCore"
-I"..\..\..\..\Qt\4.5.2\include\QtGui" -I"..\..\..\..\Qt\4.5.2\include"
-I"..\..\..\..\Python26\include" -I"..\..\_qt" -I"."
-I"..\..\..\..\Qt\4.5.2\include\ActiveQt" -I"release"
-I"..\..\..\..\Qt\4.5.2\mkspecs\default" -o release\qpycore_qstring.o
qpycore_qstring.cpp
qpycore_qstring.cpp: In function `QString
qpycore_PyObject_AsQString(PyObject*)':
qpycore_qstring.cpp:100: error: invalid conversion from `Py_UNICODE*' to
`const ushort*'
qpycore_qstring.cpp:100: error: initializing argument 1 of `static
QString QString::fromUtf16(const ushort*, int)'
This is with PyQt configured using:
configure.py --consolidate -c -j 5 --enable QtCore --enable QtSvg
--plugin
qjpeg --plugin qtiff --pluginqgif --plugin qsvgicon
Is this a supported configuration? Would it be best to try to build
Python
with mingw or rebuild Qt and PyQt with Visual Studio Express?
My recommendation is to use the compiler used to compile Python which for
Python v2.6 is MSVC 2008. I don't test with MinGW.
That said, I suspect the fix to the above is just to explicitly cast to
const ushort *. If that works then tell me.
I should have tried that myself. That works fine.
I now have a linker error for the SVG plugin for some reason. I had to add
-lQtSvg in the link command line. I thought I had configured PyQt for SVG.
The demos seem to work fine, thanks!
