Cannot get Music View to show anything

[pcchy...@gmail.com]

Hello everyone:

I used Frescobaldi extensively a couple of years ago and as a result I have a large folder of music in Lilypond format with accompanying midi and pdf files.

However, when I load these files into Frescobaldi 3.0.0 and 3.1.1 it does not load the pdf file in to the Music View.

I am sure this is related to Poppler, but despite lots of googling and reading the code and testing the imports in the code, it still doesn't work.

I am running Linux Mint 19.3

I installed Frescobaldi 3.0.0 from the repository and was getting the "Popplerqt5 module not found"  error.

I cloned the application from git and run it (3.1.1.) from the cloned repository and while the message about popplerqt5 is no longer there I still don't see anything in Music View. No errors appear when I run it from the command line and as far as I can tell I have installed all the dependencies using either the Linux Mint package manager or pip.

The information generated when I want to report a bug is telling as it shows no poppler and no python-poppler-qt as pasted here:

Frescobaldi: 3.1.1
Extension API: 0.9.0
Python: 3.6.9
python-ly: 0.9.5
Qt: 5.13.2
PyQt: 5.13.2
sip: 5.0.0
poppler: unknown
python-poppler-qt: unknown
OS: Linux-5.3.0-40-generic-x86_64-with-LinuxMint-19.3-tricia

Any ideas what I can do to fix this?

Thanks.

Peter

I would start with trying to work on a cleaner environment. Use pip
uninstall to remove the dependencies and try only the distro packages.
Then check if you can import the module in a python prompt:

python3
>>> import popplerqt5


Then run frescobaldi from terminal.

sip 5... I still use sip 4.19.19 in Fedora.
What's the version of python-poppler-qt5 Mint package? Which packages
depend on?

This is what I have in Fedora 31:

$ dnf repoquery --requires --resolve python3-poppler-qt5
glibc-0:2.30-10.fc31.i686

python3-0:3.7.6-2.fc31.i686

The problem appears to be with poppler-qt5

I used a virtual environment and did the install in the suggested order.

When I get to the installation of python-poppler-qt5 I run into several errors.

First problem was that there is no sipdistutils

I installed that from sourceforge

next issue was no qmake

Ultimately this gets bogged down in the installation, and  I haven't worked through it long enough to see if I can fix it

Googling the problem seems to indicate that it may not be a simple solution....

Hi Peter,

The problem appears to be with poppler-qt5

I admit that this has always been the most likely candidate for problems, mostly because distro packagers hadn't updated it in sync with other packages.

I used a virtual environment and did the install in the suggested order.

When you say "suggested" what exactly do you refer to?

If you followd the instructions on frescobaldi.org then please have a look at the more step-by-step instruction on https://github.com/frescobaldi/frescobaldi/wiki/Run-Frescobaldi-3-on-Linux

I'm pretty sure that I had updated that site after installing on a pristine Linux Mint 19.2 installation.

When I get to the installation of python-poppler-qt5 I run into several errors.

The above Wiki page lists python3-poppler-qt5 as a dependency, so if you actually tried to install python-poppler-qt5 (the Python 2 variant) that may well have been the culprit.

If this really is the case we should definitely update the page on frescobaldi.org, presumably replacing the whol description with a link to the Github Wiki.

Ah, Ok, now I understand.
I tried setting up frescobaldi in a virtual environment in the past and
I had similar problems. See here:
https://github.com/frescobaldi/frescobaldi/issues/911#issuecomment-507748926

Don't use virtualenv, unless you know how to fix it :-)

[pcchy...@gmail.com]

Hi again:

Thanks Urs and Federico.

On the advice of Urs, I removed Frescobaldi completely and followed the guide on https://github.com/frescobaldi/frescobaldi/wiki/Run-Frescobaldi-3-on-Linux

I

I also followed the advice of Federico and stopped using virtualenv.

Here is what happened. Everything was fine until I tried to recompile python-poppler-qt5. I must admit that I am a bit confused about python-poppler-qt5 and python3-poppler-qt5. I understand the reason for the difference. My package manager says I have python3-poppler-qt5 installed. So why am I trying to rebuild python-poppler-qt5?

Anyway, here is what happens...

As you can see there seems to be some kind of error with the "sip" command and I'm stumped.

Upgrade sip to at least 4.19.9, older versions don't have the -n option.

If your distro has python3-poppler-qt5, then you shouldn't need to
build it from source.
Can you please paste the output of:

$ python3
>>> import popplerqt5

If no output, it works fine.

I think he's using sip 5, according to the version retrieved by
Frescobaldi (see first message in this thread).

Try removing PyQt5 in your home directory.
Probably this command:

pip uninstall --user PyQt5

In general, try using consistently the dependencies from one source
only, preferably from the distro.

pip3

Right, pip3 is safer.
In Fedora 31 pip uses pip3... don't know about Mint.

[Urs Liska]

If I'm not mistaken this depends on whether Python2 is installed. If
you have Python 2 then pip uses that, otherwise the behaviour you
describe doesn't make sense.

Thanks everyone, I have it working.

Please note that in the following paste, for brevity, I deleted a
whole bunch of file paths (marked by *****(Deleted a whole bunch of
file paths)**** )

Your advice was helpful even though, as you will see belowe, some of
it required some syntax changes. eg there is no "pip3 uninstall
--user" option

I am happy.

Thanks again!

Peter
