Linux installation

[gorgobacka]

Is it possible to provide precompiled versions for Linux or at least provide the steps to install it (using the source)?

[sealsrock12]

Currently, one of the plugins we use does not have Linux support, so we cannot build it for Linux. But it is in progress.

[pinpox]

Any updates on this? Linux support would be great

[sealsrock12]

The plugin still doesn't support linux. You can track its development on https://github.com/flutter-webrtc/flutter-webrtc/issues/492, but it doesn't seem like they're making much progress.

[PeterNjeim]

No updates. We want to have Linux support. As we've said many times in the Discord, the moment one of the plugins we're using supports Linux, we'll release the Linux version. There's literally nothing we can do right now (the plugin requires a rewrite).

People have had success using Lutris and Wine, at least when not using AMD GPUs: https://discord.com/channels/774491656643674122/774491656643674128/936710744291041291.

Otherwise, use an Android emulator or a Windows VM.

[pinpox]

As I assume the app uses the API, would it be possible to share the necessary request? Maybe Linux Users can work around this with a few curl requests manually until it is fixed.

[PeterNjeim]

@pinpox if it were that easy, this app wouldn't exist, and the CLI tool would have MSCZ support. We are supporting as many platforms as we can. The app is not compilable on Linux in its current state, please use Wine + Lutris if you aren't on an AMD GPU, otherwise, use an Android emulator or VM, or Windows VM, they work.

[MeGreen]

Hi, Flutter-webrtc added two releases in the last week regarding linux support, with i guess a more polished 1.0 version being close to finish it seems. It would be awesome, if this app would become supported on linux natively soon :)

[PeterNjeim]

Thanks for the heads up but we already knew that and made a Linux version already, it'll be releasing soon

[PeterNjeim]

Soon™ has arrived. I only tested it on Ubuntu 22.04 so you guys need to test it to see if I need to fix anything

[MeGreen]

Manjaro Gnome with Wayland, fuse2 v2.9.9-4: doesn't install:

chmod a+x ./LibreScore.AppImage
./LibreScore.AppImage --install
/tmp/.mount_LibreSNCJ5ld/AppRun: line 7: 11369 Segmentation fault      (core dumped) "${APPDIR}/setup" "$@"

[PeterNjeim]

Well, can't really diagnose it with just a segfault, obviously my first question is, are you using x86_64 or arm64

[MeGreen]

Sorry, my fault :| x86_64 64bit, AMD Plattform

Is there a verbose option, or something similar?

[PeterNjeim]

Well, as the segfault says, there is a core dump. Analyzing a core dump is kind of a tedious task, don't really feel like doing it right now lol, stayed up late today. I'm also on AMD, so that's not the issue. Something I'll ask you to do before I go to bed is to run ./LibreScore.AppImage --appimage-extract. It'll extract the contents of the appimage into a folder. AppRun is the main "initial" binary. Maybe you can skip it and run librescore directly (without installing).

[MeGreen]

´´´ ./AppRun ./AppRun: line 12: /librescore: No such file or directory ./librescore ./librescore: error while loading shared libraries: libselinux.so.1: cannot open shared object file: No such file or directory ´´´

Sleep well, i may go poke also a bit

[PeterNjeim]

You can't run AppRun when it isn't in the AppImage as the APPDIR variable isn't set. You can run APPDIR=. ./AppRun to set it to the current directory (will only work if you are cd'd into the extracted AppImage's directory). As for the librescore shared library error, I know how to fix it, and will release a fix soon

[MeGreen]

No Stress, thank you for investement.

[PeterNjeim]

Anyways, you seg faulted while running the setup script. It's just a bash script so it's surprising it seg faulted. Try running ./setup --help and see if it prints the help message. If it does, try running ./setup --install (it'll probably fail, but it's just to see what's causing the seg fault exactly). This is my last message for today, thanks for debugging for me

[Xmader]

Is it possible to build the AppImage on a lower version of Ubuntu? (<= 18.04, maybe in docker since Github Actions has deprecated the Ubuntu 18.04 runner)

It seems that the segfault comes from the bundled libc.so.6 (GLIBC_2.35).

[PeterNjeim]

I can remove the bundled libc and let it use the system version

[Xmader]

No. The minimum version of libc is set to 2.34 during compile time.

./librescore: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by ./librescore)
./librescore: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by ./lib/libflutter_webrtc_plugin.so)
./librescore: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.33' not found (required by ./lib/libstdc++.so.6)
./librescore: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by ./lib/libstdc++.so.6)
./librescore: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by ./lib/libstdc++.so.6)

I am using Ubuntu 18.04, and it comes with glibc 2.27. (I somehow installed GLIBC 2.31)

[Xmader]

The reason the bundled libc.so.6 failed is that it isn't using a corresponding ld-linux.so.2. https://stackoverflow.com/a/851229

The path of ld-linux.so.2 is an absolute path so it didn't get bundled into the AppImage.

ldd librescore:

...
/lib64/ld-linux-x86-64.so.2 (0x00007fd5e670b000)
...

---

I could let it use a relative path by patchelf --set-interpreter lib/ld-linux-x86-64.so.2 ./librescore, and https://github.com/LibreScore/app-librescore/blob/6d486031790dd4053fc8617ee01954d3f33c0cb0/.github/workflows/build_app.yaml#L67 could bundle it into the AppImage.

The segfault has disappeared but it comes to get a new error that can't display the GUI

libGL error: MESA-LOADER: failed to open swrast (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)
libGL error: failed to load driver: swrast

libstdc++.so is different from the one used by the OS.

[PeterNjeim]

@MeGreen please try version v2.0.48: https://github.com/LibreScore/app-librescore/releases/download/v2.0.48/LibreScore.AppImage

[pinpox]

It runs for me, but I can't find anything. This is all I get:

Tried searching for Rush E or https://musescore.com/user/30667655/scores/6862109 and both didn't return anything. Is it broken or am I doing something wrong?

[PeterNjeim]

@pinpox The screenshot you shared is of the downloads tab, so maybe that was a mistake, but I'm sure you meant that no results appear in the home tab. I've seen other people face this issue before, it's therefore not Linux-related and so I won't be helping you in this issue unfortunately. Try the Discord server (found at the top of the README) for support questions

[pinpox]

Thanks for the clarification. I'll try the Discord, this seems like a (separate) bug though, worth investigating if others are having this as well.

[MeGreen]

Hi, sry i had a friend over for a few days, and then rehearsal weekend with my orchestra, so i hadn't the time.

Unfortunately version 2.0.48 didn't work for me neither.

with .48 this is the requested outputs:

cd squashfs-root

./setup --help
  -h, --help
  -i, --install
  -u, -r, --uninstall, --remove

./setup --install
Error
cp: cannot stat '': No such file or directory

I've also tried executing everything from my home directory instead of my externally mounted Downloads, but no change there. The same error messages with different paths.

glibc is installed as confirmed by pacman with version 2.36-6

As an inspirations by @Xmader , this is my output of ldd librescore

For their other suggestion, i don't have enough experience with github and building appimages to quickly try them out.

[PeterNjeim]

@MeGreen I actually deleted the message with the requested commands lol, didn't expect you to still try them. In this case I actually wanted you to just run the AppImage normally, though I can assume that it'll result in the glibc error that you shared

[MeGreen]

Understandable^^. But normal installation just gives a segfault with the same erorr again, i'm sorry.

[PeterNjeim]

Is that for --install? How about running the AppImage without any flags, just ./LibreScore.AppImage

[MeGreen]

Yes, that's for --install. Just running gives

./librescore: /tmp/.mount_LibreStUEW8h/lib/libc.so.6: version `GLIBC_2.36' not found (required by /usr/lib/libstdc++.so.6)

[PeterNjeim]

@MeGreen @Xmader @gorgobacka @99thGamer9 @Barmarel Please try version v2.0.49: https://github.com/LibreScore/app-librescore/releases/download/v2.0.49/LibreScore.AppImage

Just run ./LibreScore.AppImage to run, or ./LibreScore.AppImage --install to install, followed by librescore. (Run ./LibreScore.AppImage --uninstall if you want to uninstall)

[Xmader]

It gives

It seems that ldd "${APPDIR}/librescore" gives out Segmentation fault because of using bundled libraries by
export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}${APPDIR}/lib"

[MeGreen]

Yeah unfortunately it's still the same X| I'm really so sorry!

[MeGreen]

Is there any way to check if it's just the appimage bundling, and not the program itself, so it may be packaged as a snap/flatpak as an alternativ? I'm not into development, i just know that these are two more very popular packaging formats for distro-agnostic packages.

[Xmader]

I think I've solved the MESA-LOADER error.

By add the LIBGL_DEBUG=verbose environment variable (export LIBGL_DEBUG=verbose), it gives out a more verbose reason of why libGL has failed to load driver

libGL: MESA-LOADER: failed to open /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so: <some_path>/squashfs-root/lib/libpthread.so.0: version `GLIBC_PRIVATE' not found (required by /lib/x86_64-linux-gnu/librt.so.1)

It turns out the program is still using the system librt.so.1.

Then I copied glibc2.35's lib/x86_64-linux-gnu/librt.so.1 into squashfs-root/lib/, everything runs perfectly.

[MeGreen]

cd squashfs-root

hope it helps

@MeGreen don't waste your time with what I sent you earlier, I'm going to release v2.0.52 shortly and you can test that one

[MeGreen]

hahahaha too late :D

[PeterNjeim]

holy moly you posted it in the same second

[PeterNjeim]

And by shortly I mean 12 minutes

[PeterNjeim]

@MeGreen @gorgobacka @99thGamer9 @Barmarel Please try version v2.0.52: https://github.com/LibreScore/app-librescore/releases/download/v2.0.52/LibreScore.AppImage

[MeGreen]

Sadly no change. I've also followed your previous instructions, the output is exactly the same. I've also made sure, that i've tried the right version. Seems to me, that it has a bit of a problem to assign the right folders to the variables?

To be fair, i also don't see a folder named librescore in the squashfs?

[PeterNjeim]

There isn't a folder named librescore, something's wrong with your linux installation. echo $PWD should show your current directory, but in this case it's empty

[MeGreen]

Okay, i'm using zsh, i will try again with bash. Maybe that it's. In the meantime, i've also tried it on my laptop, same distro+DE, but same there.

[PeterNjeim]

I use zsh, that's not the problem

[PeterNjeim]

You said the same thing's happening but so much has happened that I don't really know what exactly is happening. Please share the output of ./LibreScore.AppImage

[Xmader]

Instead of prepending APPDIR=$PWD, I think you should run APPDIR=$PWD in a separate command

[MeGreen]

oh shit it's doing something

./LibreScore.AppImage

Let me be clear here, those commands I gave you earlier, I already said you don't need to do them anymore, they aren't necessary anymore. I don't use $PWD in the new version nor in the older versions, that was just for you to test those specific commands
