我正在创建一个简单的调试线程名称数据库(因为您不能在windows中给线程名称，您只能将该名称发送给调试器)。我有这个头文件:

threadname.h

class ThreadNameMap {
public:
    void setThreadName( uint32_t id, const std::string &name );
    std::string getThreadName( const uint32_t id ) const;
    // If ID given as string
    std::string getThreadName( const std::string id ) const;
    // If no ID given, current ID is used
    std::string getThreadName( ) const;
    // A singleton getter
    static ThreadNameMap* ThreadNameMap::getInstance();
    // Static getters that use the singleton
    static std::string getName( const uint32_t id );
    static std::string getName( const std::string id );
    static std::string getName( );
private:
    ThreadNameMap() {maxNameLength = 16;};
    int maxNameLength;
    // Map of ids and names
    std::map<uint32_t, std::string> names;
}; 

这是实现:

threadname.cpp

<>之前ThreadNameMap::getInstance() {static ThreadNameMap = ThreadNameMap();返回本月;}std::string ThreadNameMap::getName(const uint32_t id) {return getInstance()->getThreadName(id);}std::string ThreadNameMap::getName(std::string id) {return getInstance()->getThreadName(id);}std::string ThreadNameMap::getName() {return getInstance()->getThreadName();}void ThreadNameMap::setThreadName(uint32_t id, const std::string &name) {setThreadName_private (id、name.c_str ());如果(id = = 1)id = boostThreadId();[id] = name;}std::string ThreadNameMap::getThreadName(const uint32_t id)如果名字。Count (id)>0返回names.at (id);其他的返回";}std::string ThreadNameMap::getThreadName(const std::string id)threadNumber = 0;sscanf(id.c_str()， "%lx"， &threadNumber);返回getThreadName (threadNumber);}/**这个被报告为未引用!!* */std::string ThreadNameMap::getThreadName() const {返回getThreadName (boostThreadId ());} 之前

我使用单例接口，我像这样在我的记录器头文件中访问它:

logger.h

<>之前# include"…路径…/setthreadname.h"#define LOGMTDBG_tmp(debuglevel, logstream) LOGMT(debuglevel (debuglevel) <<datetimeEx & lt; & lt;' ' << ThreadNameMap: getName () & lt; & lt;' ' <<__FUNCTION__ & lt; & lt;' ' <<logstream) 之前

Logger包含在许多其他cpp和h文件中-无论需要什么地方。其中一些报告未引用的符号:

我搜索了项目，但是没有任何一个类非静态方法的引用，只有 logger.h 中的一个。

我检查了许多未引用的外部符号问题，但它们都有两种可能性:

1. dll缺失-好吧，我没有使用任何dll显然
2. 函数已声明但未实现——在上面的代码中，您可以看到声明和实现以及它们都匹配

那么为什么链接器会抱怨没有被引用的方法呢?我试图改变const和移动.h文件中的静态方法，没有任何帮助。我现在真的很绝望。
