Latest version no longer works after upgrading to Sonoma

[sammirata]

I upgraded my mac to sonoma and now the software crashes on startup. Here is the crash message:

Just wanted to update that there has been some progress this week-end. I was able to rebuild the environment and got that to work with GitHub Actions as well. Also was able to grab and build WhiteSur icon & gtk theme locally (still failing on GitHub Actions). I'll try to get the theme to work on GH actions during the week. You can view the Actions tab to see the output. We're almost halfway through! I'm hoping to get the themes fully working on GH actions by tomorrow.

Credits WhiteSur and WhiteSur-icon-theme

Locally and on my environment, I can run meld without the packaging part using this new environment and theme(s). Which is pretty good news that we're on the right track. This leaves us with packaging the dmg itself (which is another big script, but I'm hoping that there aren't big changes). Hopefully next week-end.

This may also be the solution to finally being able to produce m1/m2 builds as I understand that GitHub is now offering public beta runners for the arch. My wife has an m1 laptop, but I'm not excited about building on it due to the sheer size of the packages that we have to build and I'm not excited about having to cross compile or to generate universal binaries with jhbuild either. I already tried. It's not straightforward at the moment.

I hope that I would be able to finish this quickly because I want to focus on my other project (https://github.com/yousseb/atfal-ai & https://github.com/yousseb/atfal-site) which is an effort to track missing children/people and use AI to help find them. I love meld, but as a person who has lost his brother in a way that he couldn't come back - and I keep losing family in Gaza -, I want to help reunite families who still have the chance to be reunited. Everyone is welcome to help.

[dehesselle]

Unlucky timing, I'm coming here from this upstream issue https://gitlab.gnome.org/GNOME/meld/-/issues/804 where I have begun creating a macOS app for Meld. Once I'm happy with it I'm going to propose this to become the official macOS release of Meld - at least that was the plan before I noticed that there's new activity here. I am not interested in creating a competing port and would stop doing what I'm doing, but given the fact that you're planning to shift focus to other things anyway, you might want me not to. Let me know what you think.

[yousseb]

@dehesselle I just saw your screenshot on the issue. It is awesome and well done indeed! I'm planning to get this port to work again - and hopefully if we get m1 runners to provide an m1 build. When I first started this port, there was no CI on github and I built everything on slow laptops with the following intentions in mind:

1. Provide macOS normal feel (so menus, shortcuts, etc)
2. Provide macOS normal look (hence everytime I would look at the closest macOS gtk theme)
3. Be mindful of size (trim down the libraries and files that I would bundle as much as I could - including icons, etc)

I even went ahead and added 'signing capabilities' but I ended up not getting the keys from the Apple developer program due to the fact that I moved countries and the Apple developer program was not accepting my credit card any longer since it tied my registration to the original country where I signed up.. Needed a lot of bureaucracy and paperwork which I didn't have the time/patience to do..

I'm hoping that with CI, people would be able to fork and fix help fix issues. Perhaps you could help with that when this fork eventually - and surely - breaks again? :)

[dehesselle]

I usually don't touch upstream code outside of what I need for packaging (e.g. to make an app relocatable). My focus is on the build pipeline; I have a specific JHBuild-based setup that I'm using across multiple projects so I can handle the maintenance burden, including dependency management, CI for Intel/ARM and signing/notarization of releaes. But this work takes place mostly on GitLab because I have build infrastructure there and generally prefer their CI.

Out of curiosity, have you tried upstreaming your macOS look & feel changes? Or do you prefer to stay in your fork (which is fine)?

[yousseb]

@dehesselle I have used both GitLab CI and GitHub Actions. They'll both get the job done, so no worries there. Curious: Could you share some links to the part you're doing ARM?

re have you tried upstreaming your macOS look & feel changes: Some that made sense to go upstream (shortcuts, etc). However, the main blocking point for me was that there was a homebrew and "mac ports" versions of meld that mainly relied on gtk/xorg for macOS when this project came out with no way of cleanly differentiating between the gtk/xorg build and the native gtk build. I didn't bother much to be honest then.

However, and now that you mention it, Kai and the rest of the upstream meld developers and maintainers are super nice and helpful guys. Maybe I will talk to them about guidance and see if we can get a plan to implement that. I could keep the fork just synced for the build automation but have the changes merged in upstream to reduce the work whenever a release comes out.

[dehesselle]

Yes, you can look at the work that I have done so far before I came here: https://gitlab.com/dehesselle/meld_macos

[devqore]

@canhascodez thank you for your tip.

To simply start without building it was enough to run the first two commands (cmake and meson are not needed in this case):

pip3 install pyobjc
brew install gtk+3 gtksourceview4 gnome-icon-theme desktop-file-utils itstool py3cairo pygobject3

and then I was able even to start meld from the upstream

git clone https://gitlab.gnome.org/GNOME/meld.git
meld/bin/meld

Tested only on M1 architecture.

You can also just run @yousseb's version, without cloning the upstream, by following the first part of @devqore's / @canhascodez's instructions:

pip3 install pyobjc
brew install gtk+3 gtksourceview4 gnome-icon-theme desktop-file-utils itstool py3cairo pygobject3

then:

/Applications/Meld.app/Contents/MacOS/Meld

from the terminal, launching through Finder won't work.

Ignore this - it worked once, now, back to segfault-ing on launch, stick with the source pull!

[george-vulov]

I tried @devqore's suggestion of installing the dependencies via brew, then running meld from the upstream. However, it doesn't work for me:

# ./bin/meld

[dehesselle]

gtk-mac-integration provides GtkosxApplication.

[george-vulov]

@dehesselle Thank you! Got meld running locally now. To summarize:

pip3 install pyobjc
brew install gtk+3 gtksourceview4 gnome-icon-theme desktop-file-utils itstool py3cairo pygobject3 gtk-mac-integration

Then,

git clone https://gitlab.gnome.org/GNOME/meld.git
./meld/bin/meld

It seems to be much snappier than this port of meld -- scrolling through a large diff is smoother and less laggy.

[dehesselle]

It seems to be much snappier than this port of meld -- scrolling through a large diff is smoother and less laggy.

That's because of updated dependencies. There have been significant improvements to GTK and Cairo since the last release of "Meld for OSX".

...but I already have gtk+-3.24.38 installed by brew.

This is on a 2021 M1 MacBook Pro.

[peeeeter]

TurboEncabulator9000, had the identical issue. For me it was a system python and a homebrew python that are different. Don't ask me how to set these up to consistently to use all of the correct site packages, but I suggest brew info python and just use whatever python path it tells you.

[dehesselle]

For testing purposes, run

<where_is_your_homebrew>/bin/python3 <where_is_your_meld>/bin/meld

to force the usage of your Homebrew Python.

[TurboEncabulator9000]

Thanks for the advice! It does work if I put /opt/homebrew/bin first in my .bash_profile $PATH variable. However, the window is hiding under other windows, so I have to go find it and move it to a screen with empty space available.

However:

• The menu just says "Python" so all the stuff Meld would normally put there is absent.
• There are no MacOS window decorations. It looks like a bone-stock GTK app. Not a real problem, but weird.

[dehesselle]

You are running meld directly from upstream source where the UI/UX customizations that were developed here are absent.

[andronykus]

combining answers from above, this worked ok for me, app is working from cmd line run start:

"

pip3 install pyobjc

brew install gtk+3 gtksourceview4 gnome-icon-theme desktop-file-utils itstool py3cairo pygobject3 gtk-mac-integration

brew install python3

git clone https://gitlab.gnome.org/GNOME/meld.git

/opt/homebrew/bin/python3 ./meld/bin/meld

"

enjoy :)

[carcinocron]

attempting comment Nov 1, 2023

funny graphical glitch (clicking the dock icon that says python instead of meld restores it)

looks to be working:

I haven't tested folders or a merge conflict yet. Looking good so far.

I've got this bash script in my ~/bin/meld (which is in my PATH):

#!/bin/bash

set -e # halt on error
set -x # echo cmds before executing
set -u # fail on undefined variable
set -o pipefail # force pipelines to fail on fail

/opt/homebrew/bin/python3 /Users/$USER/code/meld-build/meld/bin/meld $@

so now meld left_file.cr right_rile.cr works in new bash/fish sessions.

[alexolog]

Are we going to get a proper package in the near future? Fingers crossed.

[yousseb]

@alexolog Yes. It has taken me 2 full weekends thus far to prepare the environment that will be packaged, but it's not done yet. I'm having to rebuild again for issues with the internationalization libs - which we're not even using, but it's a dependency. I'm expecting at least this weekend, too.

[JoeLyga]

Awesome, looking forward to it!

[alexolog]

Take your time, and thank you for working on it!

Anyone else got this? meld was my diff client choice in linux but now that I am developing in a mac I just cannot find a decent alternative.

[joske]

Yes, I have the same on my hackintosh. On my M1 mac it does work 🤔

Edit: found the solution: I have several python3 versions installed (3.9, 3.10, 3.12). When invoked like /usr/local/bin/python3.12 meld/bin/meld it works!

[yousseb]

@everyone I finally have a successful build. Actually had one since yesterday morning and have spent the whole day yesterday and a good two hours this morning tinkering with GitHub Actions to fix the CI and be able to release from it. I didn't test beyond seeing the app window open up. This one works! https://github.com/yousseb/meld/actions/runs/6772677687

I'll upload the release after finishing the work day. I'll cleanup and fix any messy shortcuts that I did later this weekend. So whatever I upload today should not really be packaged to homebrew. It is just for getting the app up and running.

I hope that I'll be able to make an m1 build on GH later this week too. No promises though as I haven't read any docs on how to do this yet.

NOTE: This build will not include any new features (same source code for Meld) - except the new theme/icons and using the latest underlying libraries.

[yousseb]

Thank you guys for your patience. I would appreciate if you can help me test this one so that if there are issues that I could fix, I would try and fix them this coming weekend.

https://github.com/yousseb/meld/releases/tag/osx-20

[matthiasdiener]

Thank you @yousseb ! Is this runnable on M1? I am getting the following error when trying to run: You can’t open the application “Meld.app” because this application is not supported on this Mac..

[yousseb]

@matthiasdiener This one is compiled for x64 arch. It "should?" run with Rosetta 2, but I haven't tried it since my main macOS is still an older 2019 Intel.

I have this note above (GH = GitHub Actions which promises m1 runners): I hope that I'll be able to make an m1 build on GH later this week too. No promises though as I haven't read any docs on how to do this yet.

[bogdanbeniaminb]

Thank you, @yousseb . I'm having the same message as above, You can’t open the application “Meld.app” because this application is not supported on this Mac., when trying to run the application on an M1. Also, the application icon has a "forbidden" sign over it, even before installing.

I think it should have run under Rosetta and the issue is different. The older version (3.21.0.osx3 - Catalina) displays a different message: it says the developer isn't signed (which can be bypassed by right-click + Open) and then the app starts for a split second, before crashing. So in terms on MacOS, the older app is allowed and it doesn't throw the same message as the latest version - but of course it crashes after a split second and cannot be used. For me it doesn't seem to be a limitation of the OS, it seems the newer version is missing something that allowed the old one to run under Rosetta (??).

[pequeurb]

Darn, I was excited to see a new release, but unfortunately same problem on M2 Pro. But thanks for all the effort you're putting in!

[fekete-robert]

@yousseb Happy to say that https://github.com/yousseb/meld/releases/tag/osx-20 seems to work fine on Intel-based mac running 14.0 (23A344).

Tested comparing files and dirs, both seem to work without issues. Many thanks for your time and dedication in getting it run again!

[kaeraali-flutterint]

I can also confirm that this new build works on my Macbook Pro 2019 running 14.1 (23B74)

I did have an issue with it being unsigned initially due to my machine being fairly locked down, but I managed to overcome that

But I do see a deprecation warning in the console on launch:

/Applications/Meld.app/Contents/Resources/__boot__.py:118: DeprecationWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html

It is not supported on my M2 macbook.

M1 Pro too. :( Impatietly waiting for. :)

[ernestojpg]

Yeah, unfortunately it does not work in M1/M2. For some reasson Rosetta is not able to launch it ....

[yousseb]

intel vs arm: It looks like m1/2/3 is the current urgent task. I'll focus on this and try to get it working. Looks like the m1 runners are only available as paid runners. I'll cover the cost for this round.

@alicekaerast Signing: This will take a while. Apple is quite bureaucratic and my account is still attached to a different country. Deprecation/critical log: You get this when starting from the command line, right?

[kaeraali-flutterint]

Deprecation/critical log: You get this when starting from the command line, right?

Yes that's correct, either running from the previously created Homebrew wrapper/symlink /usr/local/bin/meld -> /usr/local/Caskroom/meld/3.21.0-r3,19/meld.wrapper.sh or from the included /Applications/Meld.app/Contents/MacOS/Meld

To be clear, Meld works, it just prints out those log lines when I run it from the CLI

[tommcc]

Works on Intel Mac 13.6 (22G120) ✅. TY

[matthiasdiener]

intel vs arm: It looks like m1/2/3 is the current urgent task. I'll focus on this and try to get it working. Looks like the m1 runners are only available as paid runners. I'll cover the cost for this round.

Let me know if I can help with something. I'm happy to build and test it locally if you like. Thanks again!

[yousseb]

@matthiasdiener Thank you! All the steps are here: https://github.com/yousseb/meld/blob/master/.github/workflows/main.yml This package that I uploaded for x64 was fully generated from this file.

Note: You would need to change setup.cfg https://github.com/yousseb/meld/blob/master/setup.cfg#L3

arch should be in this list: https://py2app.readthedocs.io/en/stable/options.html?highlight=arch#option-reference

I'm still not clear as to which it will be - arm/m1 not being in the list - so I'm guessing it will be universal or universal2, but jhbuild does not provide either directly. I experimented with building an environment that is universal. It is feasible, but it will take a significant amount of work.

So - let's hope that it py2app will take univeral or universal2 and just provide m1.

PS: Building the environment is not fun. It is super slow. If you decide to do it, be patient! :) Look at the time this took when a prebuilt-cache from pervious jobs was not found: https://github.com/yousseb/meld/actions/runs/6757833844/job/18368770549

[droplinxuser]

Hi,

Thanks for the update. But I got this when opening the app:

I'm using a 2020 Intel iMac with the latest MacOS.

[elcste]

FWIW I tried editing the Contents/Info.plist to change

<key>LSRequiresNativeExecution</key>
<true/>

to <false/>

That removed the no entry badge over the icon on my M2 MBA running 14.1. But then I got the same Launch Error message as the previous comment.

[yousseb]

@droplinxuser This one is hard to figure out - would you mind providing some more log?

1. Run from the command line - any logs there?
2. There's a python interpreter next to the Meld executable in the package. Does that python interpreter start on its own?

[droplinxuser]

I have it now.

Python binary works fine.

/Applications/Meld.app/Contents/MacOS/python
Python 3.11.4 (main, Nov  5 2023, 00:13:32) [Clang 14.0.0 (clang-1400.0.29.202)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

@droplinxuser This one is hard to figure out - would you mind providing some more log?

1. Run from the command line - any logs there?
2. There's a python interpreter next to the Meld executable in the package. Does that python interpreter start on its own?

I'm getting the same error as @droplinxuser with the same assert g_type != TYPE_NONE error. Running Contents/MacOS/python seems to run fine.

Trying to build using the CI instructions on M1 (MacOS 14.1), I got the following error while building ~gtk~ glib during build_env.sh:

Maybe the clang version is too new (Apple clang version 15.0.0 (clang-1500.0.40.1)?

Came here to say that it launches ok but have not tried it much. intel mac sonoma 14.1

@droplinxuser I see the issue.. Thanks for the report, I think I will be able to fix it. pango is linking to libpng from homebrew instead of the bundled libpng.

A quick workaround in your case would be to install libpng from homebrew until I rebuild while fixing the link.

[yousseb]

@matthiasdiener Look here for the glib compilation meson args that I'm using. https://github.com/yousseb/meld/blob/master/osx/jhbuildrc-custom#L111

Here are all the available meson options for glib. Looks like it's failing while building tests. You can go ahead and disable building tests. https://gitlab.gnome.org/GNOME/glib/-/blob/main/meson_options.txt?ref_type=heads#L80 add -Dtests=false

PS: If you're interested in seeing what others are doing for macOS, I'd recommend also looking at homebrew's build options. Here: https://github.com/Homebrew/homebrew-core/blob/50a6424c244848683d94674a17ded58cf6749c1e/Formula/g/glib.rb#L56 Then here: https://github.com/Homebrew/homebrew-core/blob/50a6424c244848683d94674a17ded58cf6749c1e/Formula/g/glib.rb#L76 (and more options down the file)

[matthiasdiener]

Thanks @yousseb ! With the changes in #148 , I was able to build and run meld on M1 natively! I've left a link to the built dmg in the PR in case someone wants to try it.
