Qt 5.9.1 non-commercial Qt Charts and Visual Studio 2015
I've got a problem concernig Qt 5.9.1 non-commercial and Qt Charts in Visual Studio 2015 (msvc2015_64). I've use the online Installer for Windows to install Qt and already checked that QtCharts is installed using Qt Maintenance Tool.
When I try to compile my programcode in Visual Studio, I get Linker Error due to unresolved external symbols. I know that I have to add the qt5charts.dll, but there is non on my system.
I have tried to compile the chartthemes example. When I use the Qt Creator, it is no problem, but it is compiles as 32 bit. Due to other libraries we need to compile our programs as 64bit.
What am I missing for using QtCharts?
Thanks in advance
@M.-Niemeyer So, you installed Qt 5.9.1 msvc2015_64?
You said the example builds as 32bit, that means you have 32bit Qt.
Make sure you installed Qt + QtCharts for msvc2015_64.
Also do you have this line in your pro file:
QT += charts
There is no need to add qt5charts.dll manually.

I am able to compile my programs using Qt in 64bit but if I try to add QCharts I get unresolved linker error because of missing dlls.
We use Microsoft Visual Studio 2015 so we don't use .pro files but have .vcxproj and .sln files instead. If I try to compile my project as Qt .pro poject with
QT += charts
it tells me that charts is unknown.
I've added a screenshot of my QT configuration according to the maintenance tool.
If I am really missing the 64bit version, how can I obtain it.
Many thanks. I've solved the problem by adding and installing UWPx64 (MSVC2015) in the maintenance tool.
This is strange. UWP means "Universal Windows Platform". This is something different to msvc2015 which is native. Qt Charts should be available for msvc2015 as well.
@jsulm The Qt5Charts.dlls were only available after installing this additional package. All other Qt-Dlls I need (Qt5Widgets, Qt5Core, Qt5Gui, ...) could allready be found in the QTDIR\bin after installing msvc2015. Somehow there was an installation problem. After altering the installation, the QtCharts-dll where added into the mscv2015_64 directory-structure. Actually I do not use the UWP package.
