OpenCV 3.0錯誤包括ocl.hpp

Question

我在ubuntu 14.04中使用opencv 3.0.0。 我安裝了AMD Catalyst視頻驅動程序，在OpenCL上使用OpenCV。

/etc/OpenCL/vendor通過「libamdocl32.so」和「libamdocl64.so」具有「amdocl32.icd amdocl64」.icd。

在OpenCV的cmake的文件，OpenCV的表現爲：

-- OpenCV modules: 
--  To be built:     hal core flann imgproc ml photo video imgcodecs shape videoio highgui objdetect superres ts features2d calib3d stitching videostab 
--  Disabled:     world 
--  Disabled by dependency:  -

--  Include path:    /home/eduardo/Install-OpenCV/Ubuntu/OpenCV/opencv-3.0.0/3rdparty/include/opencl/1.2 
--  Use AMDFFT:     NO 
--  Use AMDBLAS:     NO 
--  Use OpenCL:     YES 

當我包括ocl.hpp文件在我謨（＃包括）。編譯器返回他的信息：

In file included from main.cpp:11:0: 
/usr/include/opencv2/ocl/ocl.hpp: In member function ‘cv::ocl::Hamming::ResultType cv::ocl::Hamming::operator()(const unsigned char*, const unsigned char*, int) const’:

我需要在GPU上測試侵蝕和擴張過濾器。

有人知道爲什麼會發生這種情況？

Answer 1

您不應將ocl.hpp納入基於OpenCV 3.0的項目中，以使用ocl::function_name表示法。

編輯：有another ocl.hpp在的OpenCV 3.0 - 其意義是完全不同比2.4分支：在後一種情況下，存在所有的OpenCL充電函數定義，以及在的OpenCV 3.0它是平臺，上下文和設備相關的信息或調整。它可以包含以下命令：

#include <opencv2/core/ocl.hpp> 

你ocl.hpp從/usr/include/拍攝 - 看來你也有安裝在您的系統中的一些OpenCV的2.4.x的開發包 - 這是一個不同的分支，爲了更好的通關請刪除所有libopencv*-dev包。如果您只想使用3.0版本，它將幫助您（將刪除不明確的標題）。

您應該在cmake <your opencv 3.0 source dir>和make之後運行make install - 它會將所有必需的東西安裝到您的系統中。默認情況下，所有標題將位於/usr/local/include文件夾中。
