Qwt-5.3.0-svn: oscilloscope

Hi,
I can't run the example oscilloscope. I get this error message:

./oscilloscope: symbol lookup error: ./oscilloscope: undefined symbol: _ZN12QwtPlotCurve7setDataERK13QwtSeriesDataI7QPoin tFE

What means?

Assuming you are on Linux/X11:

"c++filt _ZN12QwtPlotCurve7setDataERK13QwtSeriesDataI7QPoin tFE"
QwtPlotCurve::setData(QwtSeriesData<QPointF> const&)

With "ldd" you can check which Qwt library will be loaded, when you run your application. With "nm /your/path/to/libqwt.so.5 | c++filt" you can see, what is in the library.

You right! It tried to use the old qwt-5.2.

Thanks.
