Description Christophe Marin 2019-06-04 11:48:28 UTC

GCC9 is less permissive than previous versions, the current QtCurve version fails to build in openSUSE:

[  111s] /home/abuild/rpmbuild/BUILD/qtcurve-1.9.0/build/.cmake_utils_base/cmake_c_macros/include_fix/qtcurve-utils/gtkprops.h: In member function 'constexpr GObject* QtCurve::GtkWidgetProps::Props::_SigConn_shadowDestroy_ObjGetter::operator()(QtCurve::GtkWidgetProps::Props::SigConn<QtCurve::GtkWidgetProps::Props::_SigConn_shadowDestroy_ObjGetter>*) const':
[  111s] /home/abuild/rpmbuild/BUILD/qtcurve-1.9.0/build/.cmake_utils_base/cmake_c_macros/include_fix/qtcurve-utils/gtkprops.h:80:24: error: a reinterpret_cast is not a constant expression

This is the first error found, there may be others.
