How can I stop warnings about unused private fields?
c++, clang, macos, qt
Solution
Per this answer, try
QMAKE_CXXFLAGS_WARN_ON += -Wno-unused-private-field
It appears that the `QMAKE_CXXFLAGS_WARN_ON` flags are added to the compiler command line after `QMAKE_CXXFLAGS`, and would re-enable that warning (because `QMAKE_CXXFLAGS` contains `-Wall`).
Problem
While compiling a collection of files in a Qt project, I'm seeing lots of warnings similar to this one. ``` In file included from /usr/local/Trolltech/Qt-4.8.6/include/QtGui/qevent.h:52: /usr/local/Trolltech/Qt-4.8.6/include/QtGui/qmime.h:119:10: warning: private field 'type' is not used [-Wunused-private-field] char type; ^ ``` Per suggestions from various searches, I did add the entry QMAKE_CXXFLAGS += -Wno-unused-private-field to the .pro file and confirmed that it shows up properly in compiler invocations but I'm still getting that warning. I'm running Qt on a Mac with clang. Thanks in advance for any insights.
