这是我的简单设置:(我隐藏了许多不需要的信息)
//AutoFocusTest.h
#include "camAVTEx.h"
class CAutoFocusTestApp : public CWinApp
{
protected:
camera_t* mCamera;
public:
virtual BOOL InitInstance();
};
//camAVTEx.h
class camera_avtcam_ex_t : public camera_t
{
public:
camera_avtcam_ex_t();
virtual ~camera_avtcam_ex_t();
//member variables
//member function declarations
}
//camAVTEx.cpp
#include "camAVTEx.h"
camera_avtcam_ex_t::camera_avtcam_ex_t()
{
//stuff
}
camera_avtcam_ex_t::~camera_avtcam_ex_t()
{
//stuff
}
//the rest are defined here in my program
//AutoFocusTest.cpp
#include AutoFocusTest.h
BOOL CAutoFocusTestApp::InitInstance()
{
mCamera = new camera_avtcam_ex_t();
}
此设置产生错误:
3> AutoFocusTest.obj:错误LNK2001:未解析的外部符号 “public:__ cdecl camera_avtcam_ex_t :: camera_avtcam_ex_t(void)” (?? 0camera_avtcam_ex_t @@ @ QEAA XZ)
从我读过的关于这个相对常见问题的所有内容来看,我没有链接导致我的camera_avtcam_ex_t函数定义无法找到的东西。但是,我无法弄清楚我可能错过了什么。我添加了所有include目录和库目录,并将库文件添加到其他依赖项部分。
有人能发现我可能遗失的任何东西吗?
答案 0 :(得分:1)
假设您的camera_avtcam_ex_t
的构造函数已定义,声明为private
,则无法实例化它。
