Re: Next round on frescobaldi dependencies

Hi Tim, The thing about installation instructions is that they have to be exact, to save time and hassle. While the page mentions Python 3, it then goes to list just Python versions of modules - no suffix 3. I have been trapped in the hamster treadmill finding this does not work, then figuring you have to use the Python 3 versions, and then finding it is short on some modules, and then finding that I just cant get F 3 to work on Ubuntu 17 no matter what I try.

Speaking as somebody with a lifetime of experience as a software developer, this is unclear, confusing, and incorrect. And it does not work on Ubuntu 17.

Urs had success installing F from the Ubuntu repository, but I don't see why we should not aim to be able to install this application stand alone. I want an install that is clean, clear, and understandable and manageable, not just a way of making the application run by any means.

I still think at this stage there is some unstated dependency on how Qt is installed that I can't fathom.

Andrew

Looking at the Frescobaldi install from source page, it clearly indicates that the Python stuff should be from the same version (3.4 or higher).  I would hope that following the recipe will result in a working install for you.

******************
Frescobaldi 3 needs Python version 3.4+, PyQt5 and Python-Poppler-Qt5. And of course python-ly and Python-PortMidi, installed for the same Python version.

Installation order:

        • Install Python 3.4 or higher
        • Install PyQt5, using the same Python version of course.
        • Install python-ly
        • Install Frescobaldi (will work, but without PDF and MIDI support)
        • Install Python-Poppler-Qt5
        • Install Python-PortMidi. If this one is difficult to install, you can also use Pygame, which too contains the Python-PortMidi library. Use the correct Python version!

******************

Hope this helps!
