We suppress these warnings in the clang code model, because Qt only started suppressing these warnings in some Qt 5.x version. https://code.qt.io/cgit/qt-creator/qt-creator.git/tree/src/plugins/clangcodemodel/clangdiagnosticfilter.cpp#n59 > Adding "-Wno-suggest-override" to analyzer's Clang Warnings DOES fix it, so > thank you! Still don't understand where it's coming from though. It looks like Clang got this new warning (that already existed for GCC) in Clang 11 (which we ship with Qt Creator). Q_OBJECT seems to only suppress suggest-override for GCC though: https://code.qt.io/cgit/qt/qtbase.git/tree/src/corelib/kernel/qobjectdefs.h?h=5.15#n155 I fail to reproduce this warning here though. > I'm also confused why we have Clang Warning "Diagnostic Configurations" under > both the "C++ -> Code Model" and "Analyzer". So you could have a small, most important set of clang warnings for the code model, and a wider set of clang warnings when you trigger the Analyzer manually.
