The current version of Harfbuzz in Solus is 2.6.1. Is your system up to date?

I am up to date. I checked in the software center and it says I have 2.6.1. Not sure why the error.

    I was downloading linux community edition, I guess I didn't click the one ending in tar.gz though. The link you provided works on my machine! thanks!

      Seems to me that there is a gap between version 1.5.0 and 2.6.1...it would be interesting to know why the oldest version works, and not the latest.

      linny Running it from the folder it is not practical. Do you need any help to make bibisco.desktop file so you can launch it from meny or pin to panel?

          I suggest to move bibisco folder to $HOME/.local/share
          Download this icon and save it in the folder where the bibisco executable file is.
          Then make a file with this content:

          [Desktop Entry]
Name=Bibisco
Comment=Novel writing software
Exec=/home/<username>/.local/share/bibisco/bibisco
Icon=/home/<username>/.local/share/bibisco/bibisco-circle-hr.png
Terminal=false
Type=Application
Categories=Office;

          Here <username> should be replaced with your username.
          save it as bibisco.desktop.
          Then move bibisco.desktop to $HOME/.local/share/applications

          If you want to run it from terminal then there some are other steps.

          I downloaded the oldest 2.0 version, it doesn't work. Version 1.XX uses Java, version 2.XX uses Node.js...I don't know whether it's important.

          
root@x200 /home/jeanste/Téléchargements/bibisco-linux-x64-2.0.0-CE # ./bibisco

(bibisco:22246): Pango-ERROR **: 20:59:03.247: Harfbuzz version too old (1.3.1)

            Bouquins I tried to build it from source but it failed. So it is better to stick the the 1.5.0 version which is the official version for linux.

            @linny In this picture you can see where I copied the bibisco folder.

            and this is my bibisco.desktop file.

            See, it is very simple.

                algent Thank you for your explanations and work. However, versions 1.XX and 2.XX are not compatible each other. I don't want to use a version that will be obsolete at any time.

                  Got it! thanks for all of your very patient help. 🙂
