Hi. I'm tryong to use opencv4 with contrib modules. Building made succesfully with some few warnings. But headers for build directory are missing such as highgui.hpp, core.hpp and so on...

can't help with codebloxx, but you have to run

make install

(from the build folder) to copy the nessecary headers/libs/dlls to


(or whatever you set OPENCV_INSTALL_PREFIX to with cmake.)

then use your_opencv_install/include and your_opencv_install/x64/mingw/lib to build your own program

Hi. I appreciate your contribution but, remember I'm on windows OS (Windows 10 64bits)

iTop gravatar imageiTop ( 2019-04-01 04:04:05 -0600 )edit

yes, that's where mingw will install headers/libs/dll's on windows (your codebloxx does not matter here)

I see, but I've already load opencv.cpb in codeeblocks and built it successfully. Nevertheless include (install) dir still empty...that's my preoccupation. Above you told me to run "Make install" but it's not possible on Windows OS on my knowledge

lol, it is. i wouldn't have been able to build opencv without ...

Ok I see. Then can you tell me step by step how can I run make install on my platform ? I tried on cmd but i got error that command is unknown

cd  C:\Users\sergio\/Documents\Logis\OPENCV\opencv\build
: (or navigate in explorer there, andpress [alt]+d   [alt]+e  to open a cmd)
mingw32-make install

: (make is call like that with mingw)
