OpenCV: No such file or directory

Since you have the /.../opencv4/opencv2 directory on your INCLUDEPATH, remove the leading opencv4/opencv2/ from the #include <opencv4/opencv2/...> directives.

If that is not it, find out whether the file mentioned in the error message exists in that include directory or anywhere.

Unfortunately it didn't help me. Maybe he is trying to immediately access the file in "core.hpp" without accessing the folder "core"?

add all of them
INCLUDEPATH += /usr/local/include/opencv4/opencv2
DEPENDPATH += /usr/local/include/opencv4/opencv2

INCLUDEPATH += /usr/local/include/opencv4/opencv2/core
DEPENDPATH += /usr/local/include/opencv4/opencv2/core

INCLUDEPATH += /usr/local/include/opencv4/opencv2/highgui
DEPENDPATH += /usr/local/include/opencv4/opencv2/highgui

simply include header files in any cpp file
#include "core.hpp"

@JoeCFD
Doesn't work =(

[JoeCFD]

[zzzKennYzzz]

@JoeCFD

@JoeCFD said in OpenCV: No such file or directory:

add all of them
INCLUDEPATH += /usr/local/include/opencv4/opencv2
DEPENDPATH += /usr/local/include/opencv4/opencv2

add all of them
INCLUDEPATH += /usr/local/include/opencv4
DEPENDPATH += /usr/local/include/opencv4

@JoeCFD
Thank you! But now the new problem

however, they are there

[JoeCFD]

from command line:
locate libopencv_contrib or locate opencv_contrib
to find where it is located. Then in your pro file add
LIBS += -Lpathtoopencv_contrib -lopencv_contrib

Hi,

Using:

CONFIG += link_pkgconfig
PKGCONFIG += opencv

Should be enough
