I was able to successfully configure, build and install Qwt for x86 and CE6 (cross-compilation) based on Qt 4.8.4.
To cross compile for CE6 I must define QT_NO_PRINTER macro (maybe QPrinter is not supported in CE6 - I don't know).
I was able to successfully configure, build and install QwtPolar for x86 too.

When I try to cross-compile QwtPolar for CE6 I must define QT_NO_PRINTER macro but this gives compile error in qwt_polar_renderer.cpp.
.\qwt_polar_renderer.cpp(231) : error C2027: use of undefined type 'QPrinter'
I see that some portion of the code in this file is conditionally excluded based on QT_NO_PRINTER macro.
But QwtPolarRenderer::renderTo() expected a QPainter inpt parameter in any case.

How can I fix this, please?
