As there is no prebuild install candidate for ubuntu 20.04 I thought I just build the software from source.
I checked out with git and found out I need OpenCV. So I searched and found a manual to install 3.4.4 on Ubuntu 18.04. Followed the guide and build 3.4.4. Sadly bluecherry won’t install with this error message:
/usr/bin/ld: bc-thread.o: in function cv::String::~String()': /usr/local/include/opencv2/core/cvstd.hpp:648: undefined reference to cv::String::deallocate()’

Damn! I checked out the latest version for OpenCV (4.3) with git, compiled and installed it. But bluecherry won’t use it as it get’s installed into /usr/local/include/opencv4 and bluecherry want’s opencv2. So renamed the old directory and linked the new to the old name. Then I got this error message:
In file included from bc-thread.cpp:32:
motion_processor.h:5:10: fatal error: opencv2/opencv.hpp: No such file or directory
5 | #include “opencv2/opencv.hpp”
So I got me the latest version for OpenCV in the 3.4 tree. That is 3.4.10 and the opencv_contrib. I build it, installed it and got then this error message:

Bummer! Well, then I went a version down to bluecherry 3.01:
wget https://github.com/bluecherrydvr/bluecherry-apps/archive/v3.0.1.zip
mv v3.0.1.zip bluecherry-apps_v3.0.1.zip
unzip bluecherry-apps_v3.0.1.zip
cd bluecherry-apps-3.0.1/
scripts/build_pkg_native.sh
- git submodule foreach --recursive ‘git clean -dxf && git reset --hard’
fatal: not a git repository (or any of the parent directories): .git
And further down to 2.8.1:
wget https://github.com/bluecherrydvr/bluecherry-apps/archive/v2.8.1.zip
mv v2.8.1.zip bluecherry-apps_v2.8.1.zip
cd bluecherry-apps-2.8.1
scripts/build_pkg_native.sh
- git submodule foreach --recursive ‘git clean -dxf && git reset --hard’
fatal: not a git repository (or any of the parent directories): .git
Is there any documentation how to build bluecherry? I could not find anything.
