opencv > 2.4.3 not found #3

Open KMShein opened 3 years ago

KMShein commented 3 years ago

I have install the 2.4.11 and 4.5.2 into my virtual box (Ubuntu). It's still giving me the error of not finding the 2.4.3. Would you please le me know how to solve it and where exactly should we put that opencv?

EricLYang commented 3 years ago

Since you installed 2.4.11, you need to update the CMakeLists.txt https://github.com/EricLYang/ORB-SLAM2-Example/blob/master/CMakeLists.txt

find_package(OpenCV 2.4.11 REQUIRED)

Same DBoW2 https://github.com/EricLYang/ORB-SLAM2-Example/blob/master/Thirdparty/DBoW2/CMakeLists.txt

find_package(OpenCV 3.0 QUIET)if(NOT OpenCV_FOUND) find_package(OpenCV 2.4.3 QUIET) if(NOT OpenCV_FOUND) message(FATAL_ERROR "OpenCV > 2.4.3 not found.") endif()endif()

opcv The compatible version was not found and also 4.5.2 versions were considered but not accepted. Is there any steps that I was missing? I really appreciate your help. Thanks.

EricLYang commented 3 years ago

If you know where is 2.4.11, you should specify the path manually, check here https://stackoverflow.com/questions/49816206/cmake-find-package-specify-path/49816516

KMShein commented 3 years ago

I tried it with "exact required" and added the path. It was not accepted as well. Do you know where to download the 2.4.3 version? 22

EricLYang commented 3 years ago

can you attach your CMakeList.txt ?

KMShein commented 3 years ago

Of course. I have attached both below. Thanks for replying.

can you try

find_package(OpenCV 2.4.11 REQUIRED /path/to/2.4.11)

opencv 3 is not supported

KMShein commented 3 years ago

I tried it with 4.5.2 and it worked but now i am having the another problem of "opencv/cv.h : no such file or directory". I think it came from ORBextractor.h. I tried comment it out in ORBextractor.h but it gave even worse errors.
