error C2872: 'IServiceProvider' : ambiguous symbol

  (2007-07-04 11:51:09)

  今天早上 被这个错误烦了很久 。。。在网上找解决的办法 竟然全是英文的 。。。更头大

  硬着头皮看了几篇 问题好像都不大一样 于是就仿佛大海捞针一般 慢慢的找吧 挨个的试

  终于 把问题解决了 回过头想想 还真不是个事 。。。但是 为了提醒自己 也为了可能也会犯这个错误的 其他的朋友们 我还是记录下来吧

  解决办法： 调整自定义的头文件和包含的系统头文件，命名空间的前后位置。因为位置不对很可能会引起在调用时候的混淆。

  不管怎么说 要长记性哦 。。。

OpenCV Change Logs

  http://opencv.willowgarage.com/wiki/OpenCV%20Change%20Logs

• The library has been reorganized. Instead of cxcore, cv, cvaux, highgui and ml we now have several smaller modules:
  • opencv_core - core functionality (basic structures, arithmetics and linear algebra, dft, XML and YAML I/O ...).

  • opencv_imgproc - image processing (filter, GaussianBlur, erode, dilate, resize, remap, cvtColor, calcHist etc.)

  • opencv_highgui - GUI and image & video I/O

  • opencv_ml - statistical machine learning models (SVM, Decision Trees, Boosting etc.)
  • opencv_features2d - 2D feature detectors and descriptors (SURF, FAST etc.,
    • including the new feature detectors-descriptor-matcher framework)
  • opencv_video - motion analysis and object tracking (optical flow, motion templates, background subtraction)

  • opencv_objdetect - object detection in images (Haar & LBP face detectors, HOG people detector etc.)

  • opencv_calib3d - camera calibration, stereo correspondence and elements of 3D data processing
  • opencv_flann - the Fast Library for Approximate Nearest Neighbors (FLANN 1.5) and the OpenCV wrappers
  • opencv_contrib - contributed code that is not mature enough
  • opencv_legacy - obsolete code, preserved for backward compatibility
  • opencv_gpu - acceleration of some OpenCV functionality using CUDA (relatively unstable, yet very actively developed part of OpenCV)
• If you detected OpenCV and configured your make scripts using CMake or pkg-config tool, your code will likely build fine without any changes. Otherwise, you will need to modify linker parameters (change the library names) and update the include paths.

• It is still possible to use #include <cv.h> etc. but the recommended notation is:

  • #include "opencv2/imgproc/imgproc.hpp"
