QCustomplot

Hello,Iam a beginner in qt.Please help me in coming out of linking issues of QCustomPlot with Qt 5.1.0

The issues are with
QPrinter printer(QPrinter::ScreenResolution);
printer.setOutputFileName(fileName);
printer.setOutputFormat(QPrinter::PdfFormat);
printer.setFullPage(true);
printer.setColorMode(QPrinter::Color);

You can check the issue in the below attached png file.
Any one suggest me which plotting library should i use for plotting sinewave in qt.

Thank you in advance

The error has nothing to do with QCustomPlot.
Do you have " printsupport" in your pro file QT variable? Have you run qmake since adding it?

You can use Qwt, QCustomPlot, or Digia's commercial offerings for technical plotting.
