Can't install on Ubuntu about obs-backgroundremoval

[doricci]

@spamnick After your command git clone ... you have to do cd obs-backgroundremoval.

But then I have an issue while running the command cmake .. && cmake --build . && cmake --install .

CMake Error at /usr/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:146 (message):
  Could NOT find LibObs (missing: LIBOBS_INCLUDE_DIR)

I installed all the dependencies like it was said in the REAME.md of the project, anyone has an idea?

You forgot a git clone https://github.com/royshil/obs-backgroundremoval.git

Example:

git clone https://github.com/royshil/obs-backgroundremoval.git
cd obs-backgroundremoval
mkdir build && cd build
cmake .. && cmake --build . && cmake --install .

[spamnick]

@fubar-coder So all commands in myDir:

apt install -y libobs-dev libopencv-dev language-pack-en wget git build-essential cmake
wget https://github.com/microsoft/onnxruntime/releases/download/v1.7.0/onnxruntime-linux-x64-1.7.0.tgz
tar xzvf onnxruntime-linux-x64-1.7.0.tgz --strip-components=1 -C /usr/local/ --wildcards "*/include/*" "*/lib*/"
git clone https://github.com/royshil/obs-backgroundremoval.git
mkdir build && cd build
cmake .. && cmake --build . && cmake --install .

Right?

[fubar-coder]

Yes, you need to make a change to the source code and add obs to the list of path prefixes (see PR #45).

There are other commands to execute after a successful installation, because obs-studio gets installed to /usr/..., while the plugin gets installed to /usr/local/...:

sudo ln -s /usr/local/lib/obs-plugins/obs-backgroundremoval.so /usr/lib/obs-plugins/
sudo ln -s /usr/local/share/obs/obs-plugins/obs-backgroundremoval /usr/share/obs/obs-plugins/

You may use mv instead of ln -s if you don't intend to update the plugin from the source code.

BTW: You don't need to/cannot install libobs-dev, but this is not an issue, because all necessary files are already installed by obs-studio (from the ppa, not the Ubuntu-provided one).

1. If you use obs-studio from the ppa (ppa:obsproject/obs-studio), do not install libobs-dev
2. Execute all commands up until (and including) mkdir build && cd build (but excluding the cmake commands)
3. Then, before the cmake commands, apply the changes in the PR #45
4. Execute the cmake .. && cmake --build . && cmake --install . commands
5. Execute the ln -s ... commands I wrote in the comment above

Hi @fubar-coder - is it possible to include this in the readme? the links were fundamental to get it working

[fubar-coder]

I don't know cmake good enough (or even at all), but it would be the better solution if you'd be able to specify the install path when calling cmake --install - including a hint in the README file. Using the links is IMHO the worse solution. It seems that it's common practice to install everything that's custom-built below /usr/local, so the default behavior is correct, but - in our case - undesirable.

[tallship]

I don't understand why there can't be precompiled ready to go so we just unzip or tar zxf the archive, then dump the directories into ~/.config/obs-studio/plugins like the instructions for other plugins say to do. Can we have something like that @royshil ? Or is there a reason why it needs to go into /usr/..., with or without the symlinks?

The instructions for building from source were very unclear, at least I was able to find this issue, and hopefully, pr #45 has been incorporated into the Master branch, since that is seemingly where we're going to pull the source from to build it.

Right?

Thanks :)

ubuntu versions now work
