Unable to finish tutorial "Step 3. Adding object detection" due to failed to download opencv files from Conan
Answered
I wonder how can I finish this tutorial found in knowledge base (https://support.networkoptix.com/hc/en-us/articles/360057029774-Step-3-Adding-object-detection). When I went through the "Installing and linking OpenCV framework" part, I got this error:

opencv/4.1.1@networkoptix/stable: Trying with 'conan-center'...

Then I found this article in community (https://support.networkoptix.com/hc/en-us/community/posts/1500000915941-Installing-OpenCV-for-the-OpenCV-object-detection-plugin-). I changed the conan url and opencv version in CMakeLists.txt, but still got same error:

Hello James,
It's a known issue. I'm sorry for making troubles with that.
I hope, we'll fix it next week along with several other bugs.
I'll update here later.

Hi James,
I've just rechecked in the completely new directory.
git clone https://github.com/networkoptix/nx_open_integrations.git
and followed the instructions in the cpp/vms_server_plugins/opencv_object_detection_analytics_plugin/readme.md. Everything works for me.
"Run CMake" reports this error:
Could you please share the cmake command line you are starting?
Could you please share the output of these command?
conan search
conan remote list
conan profile show defaultMake sure you don't have another OpenCV version installed with conan by using this command.
conan search
Just remove each of them by
conan remove
Make sure you have the Conan center in your remotes
conan remote list
here is the command for adding it as a remote
conan remote add conancenter https://center.conan.io

Hi Andrey,
I tried to remove existing nx_open_integrations folder and did a fresh got clone.
I also use cmake command directly, for example:cmake -DmetadataSdkDir=/root/develop/metadata_sdk/ -DCMAKE_BUILD_TYPE=Release ../step3
Still, I got same error.
Here is the complete CMakeOutput.log."conan search" returns:

James,
Please, do the following.
conan remove opencv/4.1.2
conan remote remove nx_open_intergrations
conan remote remove conan-centerTry again.

Andrey,
I execute all these commands and still get same result.

James,
The issue is about your environment, not about the code in the repository.
Something strange is happening in your system.
What is your linux flavour, version?
The message appears several times:
/usr/lib/python3/dist-packages/requests/__init__.py:80: RequestsDependencyWarning: urllib3 (1.25.11) or chardet (3.0.4) doesn't match a supported version! RequestsDependencyWarning)
It's about the python requests module. I highly recommend updating your OS of at least the python and its modules.
Here is the output, revealing the root cause.

You don't have several options
arch=x86_64
arch_build=x86_64
os=Linux
os_build=LinuxI have in my conan profile.
You should configure at least two of them:
arch=x86_64
os=LinuxThe error message
ERROR: opencv/4.1.2: option 'with_gtk' doesn't exist
is about the conan recipe trying to apply options absent and to be removed for the specific OS, that is not indicated in your profile.

James,
Sorry for misleading you. My bad.
These
arch=x86_64
os=Linuxhave to be settings, not options.
Like this
$ conan profile show default
Configuration for profile default:
[settings]
compiler=gcc
compiler.version=7
compiler.libcxx=libstdc++11
build_type=Release
os=Linux
arch=x86_64

Thank you Andrey,
"cmake -DmetadataSdkDir=/root/develop/metadata_sdk/ -DCMAKE_BUILD_TYPE=Release ../step3" is fine now, however, when I do "cmake --build . --config Release", it complains about "No such file or directory".

James,
You have gcc version 7, where <filesystem> has to be <experimental/filesystem>. The
-lstdc++fshas to be linked, as well.We moved from the experimental features to the c++17 standard, and to comply with that the code was changed accordingly.
You need to upgrade you gcc at least to the version 8.
We'll fix the readme.md in the repository to reflect this prerequisite.

Thanks Andrey,
I can now build through step3~ step5 after upgrading gcc to version 9.
Your support is much appreciated.

Hello Steve Techs,
Most probably you don't have libopenjp2 installed in your OS.
Could you please create a separate thread on the forum if installation of the libraty does not help?
Please, provide OS, cmake, canon, g++ versions as well as step by step description of what you are doing with commands utilized.
