QWT plugin not showing up in creator windows. qwt-6.1.3

[rafael]

i have built qwt-6.1.3 using visual studio 2013 64 bit.
i have setup QMAKEFEATURES AND QT_PLUGIN_PATH environment variable.

i can create the widgets programmatically.
The widgets show up in designer also but it does not show up in creator.

when i click on tools -> form editor- > About Qt design plugins.

i get
failed plugins
C:/qwt-6.1.3/plugins/designer/qwt_designer_plugin.dll
cannot load library c:/qwt-6.1.3/plugins/designer/qwt_designer_plugin.dll: %1 is not a valid Win32 application.

I'm using qt 5.5.1 64 bit install package.

Do i need to rebuild qt creator for the plugin to work?

Hi,

You need to use the same version of Qt and compiler used to build Qt Creator in order for your plugin to get loaded.

Depending on your current setup, it might be simpler to rebuild Qt Creator.

Are you building your plugin with a Qt 5.7.0 for Visual Studio 2013 in 32bit ?

@SGaist thank u!
i Compile by visual studio 2015 32bit,
2015 and 2013 linked the dll is different???? surprised!

Visual Studio versions are not compatible one with the other so you can't mix and match, you always have to build everything with the same version. That's nothing Qt specific.
