Error with compiling OS/2

[Elbert P. <elb...@gm...>]

Hello,

I tried to compile v6.1.0 with Qt v4.7.3

But the examples gives errors:

cpuplot.cpp: In member function 'void CpuPlot::legendChecked(const
QVariant&, bool)':
cpuplot.cpp:202: error: 'infoToItem' was not declared in this scope
cpuplot.cpp: In member function 'void CpuPlot::showCurve(QwtPlotItem*,
bool)':
cpuplot.cpp:214: error: 'itemToInfo' was not declared in this scope
make[1]: *** [obj\cpuplot.obj] Error 1
make[1]: *** Waiting for unfinished jobs....
compiling moc\moc_barchart.cpp


Any idea how to solve this ?
