flycapture2.h和「class Error」

Question

我的英語不好。 我正在研究使用實時555的直播視頻，但我不從一個文件流，我從現場攝像機流。下面是在代碼文件中的一個，我從互聯網上獲得：

#ifndef PG_CAMERA_H 
#define PG_CAMERA_H 
#include "FlyCapture2.h" 
#include <unistd.h> 
#include <time.h> 
#include <cv.h> 
#include <highgui.h> 
#include <mutex> 
#include <thread> 
#include <base.hpp> 
#include <memory> 
//#include <tr1/memory> 
#define SOFTWARE_TRIGGER_CAMERA 

using namespace FlyCapture2; 
using namespace std; 
using namespace cv; 

/*s=vectors for storing camera and asssociated settings */

typedef std::vector<std::shared_ptr<FC2Config>> vec_config; 
typedef std::vector<std::shared_ptr<TriggerMode>> vec_TriggerMode; 



class PG_camera 
{ 
public: 
PG_camera();

//void initialise();

void get_max_res(int camera_number, int *width, int *height); 
int get_number_cams(void); 

vec_CamInfo VCamInfo;

vec_TriggerMode Vtrigmode; 



unsigned int number_of_cams; 
vector<bool> iscolor; 
vector<int> N_images; 
//int N_images; 
int camera_mode; 


void set_colour(unsigned int camera_number, bool colour); 
void PrintBuildInfo(); 
void PrintCameraInfo(CameraInfo* pCamInfo); 
void PrintError(Error error); 
bool CheckSoftwareTriggerPresence(Camera* pCam); 
bool PollForTriggerReady(Camera* pCam); 
bool FireSoftwareTrigger(Camera* pCam); 
int initialise_format7(Camera *cam, Format7ImageSettings  *image_settings, bool colour, Mode mode); 
int trigger_mode_setup(TriggerMode *triggerMode, Camera *cam, int k_numImages); 
void configure_strobe(Camera *cam); 


}; 

#endif // PG_CAMERA_H 

我已經加入庫和包括（標準，OpenCV的，flycapture ....），但目前還沒有庫和包括定義「類錯誤」。所以任何人都有這個問題，你能給我一些建議嗎？ 感謝您的閱讀！

這個問題對我來說至少是錯誤是模棱兩可的。所以你必須指定：

void PrintError(FlyCapture2::Error error);
