将静态openCV库与Visual Studio和QT Creator链接时出现LNK2005错误
将静态openCV库与Visual Studio和QT Creator链接时出现LNK2005错误
提问于 2012-03-14 16:03:07
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，我得到了以下错误：

在CMake上，当构建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，这就解决了这个特定的问题

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

问题似乎是您的链接器试图将不同的、不兼容的Visual C++运行时库(CRT)版本组合成一个单独的二进制文件。
让我猜测一下:项目的每个部分和您链接的库都不是使用Visual C++中相同的代码生成选项生成的。
我想知道/NODEFAULTLIB交换机是否能解决这个挑战？
