我有一个通过cmake使用clang-tidy的构建：
set_target_properties(project
PROPERTIES
...
CXX_CLANG_TIDY
"/usr/bin/clang-tidy"
"-checks=modernize-*,readability-*,performance-*"
"-fix"
)
构建它时，我在Qt库内部可能出现内存泄漏：
/opt/Qt5.7.0/5.7/gcc_64/include/QtCore/qobject.h:242:16: warning: Potential memory leak [clang-analyzer-cplusplus.NewDeleteLeaks]
return connectImpl(sender, reinterpret_cast<void **>(&signal),
^
.../a.cpp:27:5: note: Taking false branch
if (not inputQFile.makeAbsolute()) {

/opt/Qt5.7.0/5.7/gcc_64/include/QtCore/qobject.h:242:16: note: Potential memory leak
return connectImpl(sender, reinterpret_cast<void **>(&signal),

我该如何沉默？
我已经尝试过的
将
// NOLINT添加到a.cpp：33的末尾->无效将
// NOLINT添加到qobject.h：242->无效将qobject.h：242包裹在
#ifndef __clang_analyzer__->中无效将所有qobject.h包裹在
#ifndef __clang_analyzer__->中无效将
// NOLINT添加到connectImpl的所有行-> clang-tidy崩溃@Tarod：
这是我目前拥有的：
#ifndef __clang_analyzer__
return connectImpl(sender, reinterpret_cast<void **>(&signal),
receiver, reinterpret_cast<void **>(&slot),
new QtPrivate::QSlotObject<Func2, typename QtPrivate::List_Left<typename SignalType::Arguments, SlotType::ArgumentCount>::Value, // NOLINT
typename SignalType::ReturnType>(slot),
type, types, &SignalType::Object::staticMetaObject); // NOLINT
#endif //__clang_analyzer__
最佳答案
我认为您必须注释所有5行connectImpl（）或类似内容，因为// NOLINT仅影响单个代码行。(1)
