Topic: (build notes linux) HOW-TO upgrade cython3 Ubuntu 18.04

Hello ,

i have seen that newer svp4linux relies on


# Cython for Python3
sudo apt-get install cython3 => 0.28


however ubuntu 18.04 LTS offers only version 0.26 of cython3


i have however upgraded "cython" package via pip so

cython --version give Cython version 0.29.19



but i understand that version cython3 is needed or am i wrong?

how could i update the system version of cython3 on 18.04 to match svp4tube's requirement?


Thank you very much.

wrong. vapoursynth relies on cython3 >= 0.28

thanks,

i have installed

via pip3

sudo pip3 install cython

cython --version
Cython version 0.29.19

and cython3 i do seem to be able to install only via repository and it would yield

Package: cython3
Architecture: amd64
Version: 0.26.1-0.4
Priority: optional


is it still necessary i presume to install a *upgraded* "cython3" package to get a functional svp4linux with mpv?

tried with pip3 to install cython3 but it failed.

if you want to build vapoursynth it will throw an error if you don't have cython3 >= 0.28

in fact, svptube would not start any videos.
is it possible to install cython3 manually somehow?

Thank you,

it seems that the requirement for Cython is met with

as the build instructions state

# Cython for Python3. !!! Vapoursynth requires Cython >= 0.28 !!!
sudo apt-get install cython3

i have infact now "cython --version 0.29.19" installed viy pip3.


However, SVptube is not picking up any links anylonger, so it seems the older building instructions are no longer 100% valid (or equally probably, i just made an error when compiling according to them)
