gvedit doesn't build in Mac OSX qt: stable 5.15.1 and Xcode 12.0.1 (clang 12.0.0)
Steps to reproduce
autogen.sh, I didn't try cmake yet
In file included from main.cpp:20: In file included from /usr/local/Cellar/qt/5.15.1/lib/QtWidgets.framework/Headers/QApplication:1: In file included from /usr/local/Cellar/qt/5.15.1/lib/QtWidgets.framework/Headers/qapplication.h:43: In file included from /usr/local/Cellar/qt/5.15.1/lib/QtWidgets.framework/Headers/qtwidgetsglobal.h:43: In file included from /usr/local/Cellar/qt/5.15.1/lib/QtGui.framework/Headers/qtguiglobal.h:43: In file included from /usr/local/Cellar/qt/5.15.1/lib/QtCore.framework/Headers/qglobal.h:105: /usr/local/Cellar/qt/5.15.1/lib/QtCore.framework/Headers/qcompilerdetection.h:590:6: error: Qt requires a C++11 compiler and yours does not seem to be that. # error Qt requires a C++11 compiler and yours does not seem to be that.
Despite CXXFLAGS='-Wall -g -O1 -Wc++11-extensions' at configure time.
I made some progress on other issues, like adding QT += widgets printsupport and not finding #include <gvc/gvc.h> but eventually got stuck with needing DGVEDIT_DATADIR to be defined through gvedit.pro After running automake and qmake enough times I lost my changes and need to take a break.
Anyway, just letting others know it's broken.
