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.
