Again QWT plugin in QtCreator

[hubipet]

Hello

i have a, maybe, strange behavior with the qwt-plugin in qtcreator(designer)
I compiled qwt 6.0.0 successfully and copied all libs to the required places.
Then I copied the qwt plugin to /opt/QtSDK/Desktop/Qt/473/gcc/plugins/designer.
If I run QtCreator as root, I can see all Qwt widgets
If I run QtCreator as a user I get libqwt_designer_plugin.so is not a valid Qt plugin.

has anyone anyone an idea?

"make install" ( not you ! ) copies everything to the right places, Then you have to configure your environment like it is described in the INSTALL file.
