Qwt 5.x doesn't work with Qt 5, you need at least Qwt 6.x.

Qwt 5.0.2 has been released 2007 - is this really the version you want to use ?

Uwe

when i try to install Qwt 6.0.1
qmake
mingw32-make
i got this error...

QT_STATIC_CONST has been removed in Qt 5.4 - but why starting with old versions of Qwt ( 6.0.1 is fro 2011 ), when trying to build with a brand new Qt 5.5 ?
Use Qwt 6.1.2 and it will work without problems.

Uwe

i installed Qwt 6.1.2 sucessfully.
and set the environment variable as

Variable name ->QT_PLUGIN_PATH
Variable value ->C:\Qt\Qwt-6.1.2\plugins
Variable name -> QMAKEFEATURES
Variable value ->C:\Qt\Qwt-6.1.2\features


when i open Qt designer ,Qwt plugin is added...
But when i open Qt creator, Qwt plugin is not included in design ..how do i fix this?

I only have experience on windows platform.
For me it's a simple copy of the plugin to my plugin dir.

e.g.
My designer.exe is installed in f:\qt\5.5.\mingw492_32\bin.
My plugin dir is f:\qt\5.5.\mingw492_32\plugins.
My qwt installation dir is f:\qt\qwt-6.3.0-svn

So I copy f:\qt\qwt-6.3.0-svn\plugins\designer\qwt_designer_plugin.dll to f:\qt\5.5.\mingw492_32\plugins\designer

When designer starts, you can see the plugin status in menu Help->About Plugins.

Hope this helps

Hi,
I have the same problem, i can see the Qwt Widget in QT Designer but not in QtCreator.
I use QT5.4, QWT6.1.2 and mingn

Do you have the solution?

Your version of the creator is not compatible and you have to build Qwt twice: one version for your application development and the other one compatible with the creator to be able to load the plugin.
Always have in mind, that the creator is a Qt application itself and is compiled/linked against specific Qt libs. Then loading a plugin that has been built against different versions of those Qt libs can't work.
