Should there be a pinned topic with the minimum supported compiler versions

It would be great to have a convenient place to find the minimum compiler versions required for ParaView versions. Right now it kind of looks like GCC is by default at 5.4 since that is the oldest compiler version for the dashboards. I’m getting the following compiler error with GCC 4.8.5:

/home/acbauer/Code/ParaView/ParaView/Qt/Components/pqMultiViewWidget.cxx:124:8: error: no matching function for call to ‘QObject::connect(QPointer&, void (pqHierarchicalGridWidget::)(int, double), pqMultiViewWidget::pqInternals::pqInternals(pqMultiViewWidget)::__lambda5)’
});
