OpenCV 3.2文件編譯？

Question

如何在Windows 10中使用opencv 3.2，mingw和命令窗口編譯C++文件（包括opencv）。（我不想使用codeblocks/Vbasic/eclipse/netbeans等軟件）。

Answer 1

嘗試使用cmake生成makefile，然後使用相同的make和build。

以下是一個cmake的最小例子，其中我使用opencv進行像素聚類。

您需要創建一個CMakeLists.txt文件並添加以下內容。爲構建你可以檢查我的github回購的更多信息： https://github.com/anubhavrohatgi/ImageProcessing.git

#include the header files located in the include folder

#Set the variables for Headers and Sources. Manually add the filenames. This 
#is useful if the files are changed, removed or name modified. 
#Better than GLOB version 
SET( HEADERS 
    include/clustering.h 
) 

set( SOURCES 
    src/main.cpp 
) 

add_executable(clustering ${SOURCES} ${HEADERS}) 

target_link_libraries(clustering 
    ${OpenCV_LIBS} 
)
