We're trying to upgrade to Qt 5.5.1, but apparently our Qt 5.5.1 Windows build is lacking an external symbol required by our Qwt 6.1.2 configuration:: QMetaType::registerNormalizedType().
We did recently successfully build our application against a Qwt 6.1.2 build with Qt 4.8.5. We're using Visual Studio 2010, 64-bit. (I'm using Windows 7).
The full error messages are below, but basically, it looks like that function is needed by these modules:
- qwtd.lib (moc_qwt_plot_picker.obj)
- qwtd.lib (moc_qwt_text_label.obj)
- qwtd.lib (qwt_plot_item.obj)
- qwtd.lib (qwt_plot.obj)
- qwtd.lib (qwt_legend_data.obj)
- qwtd.lib (moc_qwt_plot.obj)
Our qwtconfig.pri has these settings (commented out options are disabled):
- # QWT_CONFIG += QwtDll
- QWT_CONFIG += QwtPlot
- QWT_CONFIG += QwtWidgets
- # QWT_CONFIG += QwtOpenGL
- # QWT_CONFIG += QwtSvg
- # QWT_CONFIG += QwtMathML
- QWT_CONFIG += QwtExamples
- # QWT_CONFIG += QwtPlayground
Our Qt 5.5.1 build configuration has these options.
- -prefix C:\Riverware\tools\Qt-551\qtbase
- -commercial
- -nomake tests
- -debug-and-release
- -commercial
- -platform win32-msvc2010
- -shared
- -qt-zlib
- -qt-libpng
- -qt-libjpeg
- -no-opengl
- -no-angle
- -icu
- -no-strip
- -saveconfig CwQt551-ConfigOut
(Notice that our Qt 5.5.1 build is WITHOUT OpenGL and ANGLE. It's not clear that we can build the prerequisites for those with Visual Studio 2010. I don't know).
The full text of the six link errors -- all "unresolved external symbols" for QMetaType::registerNormalizedType() -- can be seen in the attached text file.
Does anyone know where QMetaType::registerNormalizedType(..) (the missing symbol) would be coming from? Or if a Qwt configuration (which would hopefully work for us) can refrain from requiring that symbol?
Thank you in advance.
