QWT plugin for QT Designer

[gandalf]

I can't get QT Designer to load the plugin qwt.
QT designer tells me that the plugin was compiled with mingw while it wants a plugin compiled with MSCV!
What can I do to solve?

[tentakel]

i have the same problem with my custom widget.

i suppose compiling qt with mingw is the mor complex way.
easy solution could be compile the qwt or custom widget with msvc.

but,............i do not know how to do this, too.
see thread http://www.qtcentre.org/threads/30381-custom-widget-with-msvc

if anybody has a solution, please post it with an instruction step by step.
