qwt_plot_svgitem Object File not Created

[caggiadj]

Howdy Y'all,

I recently added a QwtPlotSvgItem to my code base. I've declared and instantiated everything correctly but my makefile spits out

undefined reference to `QwtPlotSvgItem::QwtPlotSvgItem(QwtText const&)'

The problem is the qwt_plot_svgitem object file isn't compiling. I'm in a Linux environment, Redhat. I've tried putting in svg and xml in a couple of the .pro without any difference. A previous post from 2009 had something with this file but they were in windows. What should I add to compile this file?

I'm running Qwt 6.1.3

Sincerely,
Me
