LNK2005将静态openCV库与Visual Studio和QT Creator链接时出错 [英] LNK2005 Error linking static openCV libraries with Visual Studio and QT Creator

问题描述

我建立了静态的openCV 2.3库.我的项目目前使用动态库没有问题，但是现在我想使用静态库.我将这些库添加到了我的.pro文件中:

I built the static openCV 2.3 libraries. My project currently uses the dynamic ones with no problem, but now I want to use static libs. I added the libs to my .pro file:

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"

并包括目录:

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:

When I try to build I get these errors:

Any help or suggestions appreciated.

推荐答案

在CMake上，在构建openCV静态库时，除了取消选中BUILD_SHARED_LIBS外，我还取消选中了BUILD_WITH_STATIC_CRT，这解决了该特定问题

On CMake, when building the openCV static libraries, besides unchecking BUILD_SHARED_LIBS I also unchecked BUILD_WITH_STATIC_CRT, and that took care of that particular problem
