Hi dear community,
So I am trying to build an openCV package on a jenkins server, meaning that I don’t have direct sudo rights on there and thus cannot apt-get install stuff. The idea is to have the package built remotely, and then use the package as a downloadable library for other stuff…
I have a personal project that uses openCV, and the idea is that this personal project downloads the generted package and uses it as is, so that I don’t have to install openCV on my linux, but simply downloading the generted package is good enough.
I have managed to build the package itself, and I manage to use the generated package on my personal project via cmake (find_package(OpenCV) ) after downloading it. Compiling works as well, the only issue that remains is at execution. As soon as some functions from openCV are used, I get this error message :
OpenCV(4.5.5-dev) Error: Unspecified error (The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Cocoa support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script) in cvNamedWindow, file /home/jenkins/agent/workspace/tion_opencv_v4.5.5-testlinux64-2/opencv/modules/highgui/src/window.cpp, line 1250
terminate called after throwing an instance of 'cv::Exception'
Looking online, it seem that when building openCV, it is missing pkg-config and libgtk2.0-dev, but the catch is that I cannot run any sudo commands so I cannot run sudo apt-get install. I have access to a virtual environment, so I tried running pip3 install PyGTK pkgconfig but I still got the issue at execution.
So my question is this: is there any configuration that can be changed inside openCV cmake when building it from source to fix this ? Or any other workaround that would be worth trying ?
Hope I’m clear, happy to provide more info if not
thanks for the supprt

error means, that there was no dev libgtk or libqt available,when building the opencv libs .
so,
wont change anything (it’s too late, and not python related)
this will have the capabilities of the build box (e.g. no gui, limited video options, simd differences, etc)deployment server there is …
have a look at cv::getBuildInformation() to see, which options were built in
Hi berak, thanks for the support.
So I am running pip3 install PyGTK pkgconfig right before the openCV build, not my own personal repo, with the hope that when openCV builds, it uses these packages from the venv…
So it’s not exactly jenkins tha’s deploying the package, but conan. Anyways, when I build the package from source on my linux machine I get the “exact” same content built as on the docker image used via the jenkins job, but since my machine has the pkgconnfig and the gtk, the built package is properly usable…
as for the getBuildInformation :

again, this is a c++ lib, not python. it would need the dev c++ headers / libs, not some python wrapper (and cmake does not use pkg-config internally)
GUI
support for video files / urls (v4l / webcam only)
python 2 / 3 wrappers (!)
Indeed, and when I run the exact same commands that jenkins runs to build from source, but n my local machine, I get this config
