我正在尝试使用.avi文件作为源. (相机捕获已经可以使用.)我的项目编译没有问题,但是在链接过程中出现错误:
I'm trying to use an .avi file as my source. (Camera capture already works.) My project compiles without problems, but during linking I get the error:
undefined reference to 'cv::VideoCapture::open(std::string const&)'
我该怎么办? VideoCapture::open()的std::string重载放在哪个库中?
What should I do? In which library is this std::string overload of VideoCapture::open() put?
VideoCapture(0)(摄像头捕获)可以编译,链接和运行,因此VideoCapture(std::string)必须位于我已经与之链接的libs中的其他位置...对吧?
VideoCapture(0) (camera capture) compiles, links and works, so VideoCapture(std::string) has to be somewhere else that in libs I'm already linking with... right?
OpenCV版本:2.4.9(昨天从git复制).
OpenCV version: 2.4.9 (cloned from git yesterday).
推荐答案问题是由我使用2.4.9版本的2.4.5头文件引起的.
The problem was caused by me using 2.4.5 header files for 2.4.9 version.
