LNK2005 将静态 openCV 库与 Visual Studio 和 QT Creator 链接时出错

Question

我构建了静态 openCV 2.3 库。我的项目目前使用动态库没有问题，但现在我想使用静态库。我将库添加到我的 .pro 文件中：

LIBS += "C:\Program Files\openCV_VS_static\opencv\build\lib\Release\opencv_calib3d231.lib" \
"C:\Program Files\openCV_VS_static\opencv\build\lib\Release\opencv_contrib231.lib" \
"C:\Program Files\openCV_VS_static\opencv\build\lib\Release\opencv_core231.lib" \
"C:\Program Files\openCV_VS_static\opencv\build\lib\Release\opencv_features2d231.lib" \
"C:\Program Files\openCV_VS_static\opencv\build\lib\Release\opencv_flann231.lib" \
"C:\Program Files\openCV_VS_static\opencv\build\lib\Release\opencv_gpu231.lib" \
"C:\Program Files\openCV_VS_static\opencv\build\lib\Release\opencv_haartraining_engine.lib" \
"C:\Program Files\openCV_VS_static\opencv\build\lib\Release\opencv_highgui231.lib" \
"C:\Program Files\openCV_VS_static\opencv\build\lib\Release\opencv_imgproc231.lib" \
"C:\Program Files\openCV_VS_static\opencv\build\lib\Release\opencv_legacy231.lib" \
"C:\Program Files\openCV_VS_static\opencv\build\lib\Release\opencv_ml231.lib" \
"C:\Program Files\openCV_VS_static\opencv\build\lib\Release\opencv_objdetect231.lib" \
"C:\Program Files\openCV_VS_static\opencv\build\lib\Release\opencv_ts231.lib" \
"C:\Program Files\openCV_VS_static\opencv\build\lib\Release\opencv_video231.lib"

并包含目录：

INCLUDEPATH += "C:\Program Files\openCV_VS_static\opencv\build\include"
INCLUDEPATH += "C:\Program Files\openCV_VS_static\opencv\build\include\opencv"

当我尝试构建时出现以下错误：

任何帮助或建议表示赞赏。

Answer 1

在 CMake 上，在构建 openCV 静态库时，除了取消选中 BUILD_SHARED_LIBS 之外，我还取消选中了 BUILD_WITH_STATIC_CRT，这解决了这个特定问题

Answer 2

确保项目属性->配置属性->c/c++>代码生成：运行时库是多线程的（/MT）

Answer 3

问题似乎在于您的链接器试图将不同的、不兼容的 Visual C++ 运行时库 (CRT) 版本组合到一个二进制文件中。
让我猜测一下：项目和库的每个部分您链接的对象不是在 Visual C++ 中使用相同的代码生成选项生成的。
我想知道 /NODEFAULTLIB 开关是否可以解决这个挑战？
