Question

我有一个类，当我尝试在头文件中添加以下声明时：

bool m_DeviceIDs[100];

我遇到了分段错误。有什么想法吗？整个班级标题：

class Protocol
{
    vector<ProtocolDevice*> _DeviceProtocols;
    vector<Device>* _Devices;
    Helper _Helper;
    vector <unsigned char> m_MessageToSend;//xml messages to send
    bool m_LockDevices;
    //bool m_DeviceIDs[100];
    unsigned int GetVacantID();
public:
    Protocol(void){};
    Protocol(vector<Device>* devices);
    ~Protocol(void);
    void RemoveDevice(int DeviceID);
    void AddDevice(Device device);
    bool SendPing( int DeviceID);
    bool GetInputStatus( int DeviceID);
    void GetLowLevelConfiguration(int DeviceID);
    bool ActivateOutput(char outputID, bool state, int DeviceID);
    bool ActivateBSUHF(unsigned char state, int DeviceID);
    bool ActivateUnitLF(unsigned char state,int DeviceID);
    void StartDeviceListeners();
    void WriteMessageToDevice(int DeviceID, unsigned char* message, int length);
    vector<unsigned char> CollectDataFromDevice(int DeviceID,int dataLength);
    int GetDeviceAvailableDataLength(int DeviceID);
    void RefreshServerDetails(int DeviceID, string host, int port,int reconnectInterval);
    void ReconnectHost(int DeviceID);
    void SendVersion(int,bool);
    void StartListentoDevice(int DeviceID);
    void StopListenToDevice(int DeviceID);
    bool SendSetLowLevelConfiguration(LowLevelConfiguration llConfig, int WaitAckMS,     bool FromBaseToLocator,int DeviceID);
    bool OperateExciterRead(char operation, unsigned int ReaderID, int Retries,int DeviceID);
    bool RequestConfigurationFromLocator(int ReaderID,int TimeOut, int Retries,int DeviceID);
    void SendXMLMessage(unsigned char opcode,   vector<unsigned char> XMLData,unsigned int MessageID, unsigned int SourceID, unsigned int DestID);
    void Mute(int Length, int DeviceID);
};

您所显示的代码没有任何问题，但您可能需要尝试使用std::bitset代替bool数组，因为它更具有多种功能和空间效果，例如：

#include <bitset>
std::bitset<100> m_DeviceIDs;

C ++ Linux：在类中声明一个数组会导致分段错误
