Not compiling with qt5
The error is:
../jupedsim/src/GraphicView.cpp:97:27: error: 'class QGraphicsLineItem' has no member named 'translate' current_line->translate(pos.x()-old_pos.x(),pos.y()-old_pos.y());
The backwards compatible way is: //current_line->translate(translation_x,translation_y); current_line->setTransform(QTransform::fromTranslate(translation_x,translation_y), true);
I made the change, but you need to check.
