Dear Jean Louis,

I agree with Jean-Julien's message.
I just want to add a couple of points.

The page you link (https://www.macports.org/install.php) has a
step-by-step installation guide, including the instructions to get
Xcode and the Command Line Tools.

I agree with Jean-Julien that uninstalling Frescobaldi should not be necessary.
Anyway, if you have doubts on using MacPorts, please see the guide at
https://guide.macports.org

It seems to me that now your immediate problems are solved.
If that's not true or if anything else arises you can write to either
the LilyPond or the Frescobaldi list.
I admit I tend to disappear for long periods (due to personal and
professional reasons) and I'm very sorry for that: if that happens you
can write to me directly to get my attention.

Best wishes.
Davide

This explains also why you were not hit by the 'use_xcode' problem,
since it does not affect 10.13 and 10.14.

> Everything around qt5 seems to be a weak point of Frescobaldi,

Indeed: I appreciate greatly that it is easy to build applications
with Qt and Python, but the combination makes distributing the
software for Mac a nightmare.

The prebuilt application (not yet available for Frescobaldi 3.2 due to
personal reasons) cannot include the documentation browser and the SVG
viewer because packaging some components of Qt with Python is
impossible on Mac.
I asked for help on the PyQt mailing list a couple of times and got no answer.
If anyone is interested, details can be found at
https://github.com/frescobaldi/frescobaldi/issues/1244

Best wishes.

That's what I was thinking of doing, but on the app store you can only find the 
version compatible with the latest Mac OS (Monterey) and it requires a dozen 
Mb. Being on Mojave (10.14) it was necessary to find on the Apple site the 
version which goes well https://developer.apple.com/download/all/. There Xcode 
is 7.82 Gb and takes very very long to install.
Installing the MacOSX10.14.sdk file is endless too. too.

Finally the "standalone" applications are not so bad

Everything around qt5 seems to be a weak point of Frescobaldi, since it was

Hello Folks,

I’ve never heard about Xcode_11.3.1.xip.
The simple way to install Xcode is to take it from the App Store (needs about 
50 Mb these days).

Well, it’s unlikely. I happen to have frescobaldi installed via a fresh new
MacPort procedure (after upgrading to MacOs Monterey) just last week and
the missing sdk message I encountered was related to all the qt5 stuff that
frescobaldi needed in order to be built. You were lucky it was not a
stopper as it was in my case: I had to manually add `use_xcode yes` in the
corresponding PortFile of py310-poppler-qt5 in order to make it build
properly. Perhaps it has since been corrected so that if the «standard» way
for qt5 to find the sdk won't work, they try the `use_xcode yes` trick
(whatever it does) before giving up.

All these problems, even if triggered during frescobaldi install, are
unrelated to it. That's just the way Macport is doing the job: whenever you
add a package to MacPort, it asks you what should be present on the machine
to make your app work and then try to install it by itself, saving the user
the trouble to install all the extensions and preventing multiple installs
of the same tools whenever two different packages need the same first
building block.

But as a matter of fact, it won't help to uninstall frescobaldi to try to
correct for lilypond path (as for one reason is that MacPort don't throw
away uninstalled port but keep them somewhere, ready to reinstall
it without further building in case you change your mind). I would rather
suspect that the search for different lilypond locations was done after you
first looked there (perhaps triggered by one of your tinkering), was
written down somewhere so that the next frescobaldi startup shows it.

Happy that you finally managed to get it work and have fun coding with lily
on frescobaldi !

Re: [was: Re: ANN: Frescobaldi 3.2]

[Jean Louis THIRY]

Hello Jean,
I think I have made quite a bit of progress in the great forest of my 
ignorance. I took your advice first and installed Macport 
(https://www.macports.org/install.php) and invoked "sudo port install 
frescobaldi". Installation stopped when asked to install Xcode. It took me 
trying to figure out what Xcode was for and finding the huge "Xcode_11.3.1.xip" 
file and installing it. "sudo port install frescobaldi" again and there, 
everything goes well except that a message indicates that "MacOSX10.14.sdk" is 
missing but does not cancel the installation which goes to the end without 
problem. I find and install "MacOSX10.14.sdk". and I find in the Macports 
folder the Frescobaldi 3.2 file which I launch immediately.

There, I check that the new 3.2 features are present and after noticing that 
the help balloons and \pointAndClickOff /On did not work, I check the 
convert-ly and import xml2.ly functions. I note that these two functions do not 
go beyond Lilypond 2.20.0.
I spend a lot of time (trying to figure it out) trying all sorts of preference 
settings and other tinkering before I find that just clicking the Frescobaldi 
icon in the Mac's dock a second time and Lilypond 2.23.11 appears in convert.ly 
and in xml2.ly. Help balloons and pointAndClick too.

I have a question about the installation. Could this erratic behavior be a 
result of this .sdk file being installed in the wrong order? is it possible to 
uninstall Frescobaldi using some magic formula like "sudo port uninstall 
frescobaldi" and do an install again so that the installer finds the sdk file. 
Especially will there be a difference. Just an idea...

In any case, thank you Jean for the helping hand (effective as usual) which 
will have especially helped me to help myself. ;•)
J.L.

Re: [was: Re: ANN: Frescobaldi 3.2]

[Mike Blackstock]

I'd be more than happy to set up a Virtual Machine for you, with root
access,
so you can install different versions of Frescobaldi and have people try it
out,
accessible via a web browser (Apache/Guacamole)

Lemme know if you are interested, and what kind of Linux and or window
manager
you want installed.

Cheers,
M.

Hello,

Adding back the list in copy, please keep it so that everyone can 
participate and benefit from the answers in the future.



Le 16/08/2022 à 10:25, Jean Louis Thiry a écrit :
I just type "Frescobaldi" in the terminal. In the 'frescobaldi' folder 
there is actually a setup.py file. If I run it, I get this:

    or: setup.py --help [cmd1 cmd2 ...]
    or: setup.py --help-commands
    or: setup.py cmd --help
error: no commands supplied

very obscure to me!



The command provided in the INSTALL file is 'sudo python3 setup.py 
install', you're missing 'install'.





Before trying to install, what do you get if, inside the 
'frescobaldi' folder, you follow the procedure for running 
Frescobaldi from this folder without installing, namely 'python3 
frescobaldi’?


I'm not sure I understand the meaning of this sentence, is there a 
difference between 'folder' and 'directory'?



No :-)


in the 'frescobaldi' folder I don't see anything that allows me to 
follow a procedure to "run Frescobaldi from this folder without 
installing it".



I was referring to the first sentence from INSTALL:

"""
You can run Frescobaldi without installing. Just unpack and then run:

    python3 frescobaldi

See below for the required dependencies.
"""



If I type 'python3 frescobaldi' in the terminal, I get this:
python3 frescobaldi
The 'popplerqt5' module can't be found.
Frescobaldi can't find the 'popplerqt5' module. This module is 
required for the display of PDF documents. The module is in the 
python-poppler-qt5 package which needs to be installed.


Frescobaldi can run, but cannot display PDF documents.
Continuing...
The 'qpageview' module can't be found.
Frescobaldi can't find the 'qpageview' module. This module is required 
for the Music View and other viewers inside Frescobaldi, and can be 
downloaded from http://github.com/frescobaldi/qpageview.


Unfortunately, Frescobaldi cannot run without it.
Exiting.



Then you need to install those dependencies.

Before embarking in that: have you tried installing Frescobaldi from 
MacPorts? It's likely a lot simpler than doing this setup yourself. 
Install MacPorts if you don't already have it ...


https://www.macports.org/install.php

then type "sudo port install frescobaldi". See 
https://ports.macports.org/port/frescobaldi/


Frescobaldi relies on Python modules that have external dependencies, 
which makes the dependencies a bit complex to install if I recall 
correctly, so I think you will save yourself time with this.

In other words: nothing
I'm really sorry, I feel really ignorant and I don't want to waste 
your time with my more than basic questions (especially after 35 years

No problem here at all. Even if you were ignorant, that would not be a 
valid reason for being sorry to ask questions on this list.

Where are you running this command from? It sounds like you are not in

If you do 'ls', you should see a setup.py file.


Before trying to install, what do you get if, inside the 'frescobaldi'

Hello Jean and thank you for your answer.

I understand that it must be complicated to understand what I want to explain, 
so much I find it difficult to explain things that are beyond my understanding. 
Let's try briefly, knowing that I am to my great regret quite ignorant in terms

On my machine I use Frescobaldi 3.0 (which works pretty well and suits my needs

If I type "frescobaldi" in the terminal, I get an app called "Python" exactly 
similar to Frescobaldi, using the same preferences and the same sessions but 
which is not version 3.2 and whose info is: Frescobaldi: 2.20.0 (!!) - Python: 
3.5.9 - python-ly: 0.9.5 - Qty: 4.8.7 - PyQt: 4.12.1 - sip: 4.19.20 - poppler: 
0.61.1 - python- poppler-qt: 0.24.0. A detail however, the application crashes 
systematically when leaving.

I found all these pythons in my Mac: Python: 3.7.6, 2.7.16 , 3.7.4, 3.5.9, 
3.7.1 - Python Launcher: 3.7.6, 3.7.1, 3.7.4.
We can assume that there is a sneaky Python too many somewhere in the system 
it's possible but where does this Frescobaldi 2.20 come from? 


All the best,
JL
