C++ 链接OpenCV时未定义的符号

我正在尝试将OpenCV库的静态库链接到我的项目中，但出现错误：

Undefined symbols for architecture armv7:
  "__ZN2cv9ExceptionC1EiRKSsS2_S2_i", referenced from:
      __ZL16icvGenerateQuadsPP8CvCBQuadPP10CvCBCornerP12CvMemStorageP5CvMati in libopencv_calib3d.a(calibinit.o)
      _cvFindChessboardCorners in libopencv_calib3d.a(calibinit.o)
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我不知道符号“ZN2CV9Exception1Eirksss2_S2_I”应该是什么，也不知道我用来构建静态库的任何源文件或头文件中的字母字符串

有谁对链接器更有经验，能向我解释一下这些错误吗

编辑：01.07。还没有解决这个问题，只是选择使用calib3d退出棋盘格检测，并使用不会产生链接错误的功能2d进行不太复杂的圆检测。

很可能您将OpenCV库按错误的顺序放置。在链接列表中尝试以下顺序：

opencv_contrib opencv_legacy opencv_videostab opencv_photo opencv_缝合opencv_objdetect opencv_video opencv_ml opencv_calib3d opencv_功能2d opencv_highgui opencv_Flan opencv_imgproc opencv_core

您可以使用

c++filt

对未定义的符号进行分解，以找到实际的函数名

$ c++filt.exe __ZN2cv9ExceptionC1EiRKSsS2_S2_i
cv::Exception::Exception(int, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, int)

$c++filt.exe\uuu zn2cv9异常1IRKSSS2\uS2\uI
cv:：Exception:：Exception（int，std:：basic_string const&，std:：basic_string const&，std:：basic_string const&，int）

---

然后，您必须确定哪个源文件包含此函数，以及库中与之对应的链接。

libopencv\u core.a

。这是我链接的第一个库。。现在我放弃了使用legacy/calib3d，而是使用一种圆检测方法，使用feature2d.a。（功能2s、imgproc、objdetect和core lnk）不幸的是，在如此混乱的符号中，我看不到任何特定的函数名……包含缺少函数的库是
