Vapoursynth on LMDE

[Selur]

Okay, this will take a bit since it really seems to be difficult to install Vapoursynth in LMDE 5. 
What I did so far:
I installed LMDE5 in a VirtualBox VM and then did the following to install Hybrid:

• I opened a terminal
  
• made sure the system was up-to-date using:
  
  sudo apt update && sudo apt upgrade -y && sudo apt autoremove && sudo apt -y autoclean && sudo -y autopurge
• went to https://www.selur.de/downloads and copied the downloadlink to 'Hybrid Linux64bit (with base tools and most dependencies)'
  
• downloaded the file into my home folder:
  
  wget https://www.selur.de/sites/default/files/hybrid_downloads/Hybrid_20220320_Linux.7z
  (this download is just for the current version)
  
• I extracted the download into my home folder:
  
  7z x Hybrid_20220320_Linux.7z
• tried to start Hybrid from the command line using:
  
  ~/hybrid/Hybrid
  but noticed that DivX265 and neroAacEnc didn't work. (both use 32bit libraries that don't work on LMDE5 afaik)
  
• so created a misc.ini in that folder using:
  
  nano ~/.hybrid/misc.ini
  with the follwing content:
  
  [General] ignoreTools=DivX265;neroAacEnc
• starting Hybrid now with:
  
  ~/hybrid/Hybrid
  it reported that tsMuxeR didn't work.
  calling:
  
  ~/hybrid/tsMuxeR
  it reported:
  
  lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.29' not found
  downloading the latest tsMuxeR from https://github.com/justdan96/tsMuxer/act...2852491399
  and extracting the tsMuxeR file into the ~/hybrid folder and calling 'chmod +x ~/hybrid/tsMuxeR' solved that.
  now I Hybrid successfully started without any issues.
  
• removing the download by calling:
  
  rm Hybrid_20220320_Linux.7z

Since Hybrid itself was working I added Vapoursynth support by:

• checking the installed python3 version using:
  
  python3 --version
  since this showed that Python 3.9.2 was installed, by Vapoursynth R59 only support Python 3.8 and Python 3.10 I installed Python 3.10 by:
  • installing all needed dependencies for building Python 3.10 using:
    
    sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev libsqlite3-dev wget libbz2-dev
  • downloading latest Pythong 3.10.6:
    
    wget https://www.python.org/ftp/python/3.10.6/Python-3.10.6.tgz
  • extracting the download using:
    
    tar -xf Python-3.10.6.tgz
  • changing into the Python folder:
    
    cd Python-3.10.6
  • configuring Python for compilation
    
    ./configure --enable-optimizations
  • compiling Python using:
    
    make -j 16
    (replace 16 with the number or physical cpu cores your system has)
    
  • installing python 3.10
    
    sudo make install
  • making sure calling python3 will call the new 3.10 version.
    
  • checking that Python 3.10 was installed:
    
    python3 --version
  • making sure that python also points to python3 by installing 'python-is-python3'
    
    sudo apt-get install python-is-python3
    and caling:
    
    sudo update-alternatives --install /usr/bin/python python /usr/local/bin/python3 1
  • removing the download and the source code using:
    
    cd sudo rm -rf Python-3.10.6*
  • installing pip using:
    
    sudo apt install python3-pip sudo ln -s /usr/bin/pip /usr/local/bin/pip

Problem is when I now call:
[*]installing Vapoursynth R59:

sudo python -m pip install wheel sudo python -m pip install Cython sudo python -m pip install vapoursynth

[/list]
I end up with:

and I'm not sure how to fix that atm.
