That's known. I'm not sure how to fix it, because there is a lack of documentation about that. I hope I can comeup with a solution in the next few days, but I can't promise anything

@marchellodev Another thing to mention: You app uses a very old hover version. You can update it (same go get command as to install) and then reinit the project rm go && hover init. In the latest version you can control a lot of names for like the application, executable and the package. That won't fix your problem, but it gives you a lot more features!

@jld3103 is there a way to check the installed version of hover?
hover --version doesn't work

upd: Yep, got it, thank you

marchellodev on 23 Apr 2020

Maybe @probonopd could you explain to me how to create a correct .DirIcon? I understand if that's not your matter, but there is so little documentation on how to do that.

jld3103 on 23 Apr 2020

Simply place a png in a Linux standard icon size (e.g., 128x128px) in .DirIcon into the AppDir root directory. Normally tools that produce AppDirs/AppImages should do this automatically, e.g., by copying the icon specified in the desktop file Icon=... key there.

Ok thanks. I hope that works

@probonopd This document says that it needs be a symlink. That was what I tried, but I didn't get it to work. I think that document is outdated.

jld3103 on 23 Apr 2020

@probonopd I'm using this command: cp build/assets/icon.png .DirIcon && appimagetool .. I copies a png icon with the size of 256x256 to the .DirIcon and then builds the AppImage, but still I get this error message:

WARNING: No icons found at "usr/share/icons"
WARNING: Using .DirIcon as default app icon
ERROR: Unable to load image.
ERROR: No icon was generated for: /home/jld3103/Applications/gofluttertest-1.0.0+1_9ddc72cafd2a928b3f181bb797aac3bd.AppImage

jld3103 on 23 Apr 2020

Please also copy the icon to usr/share/icons/hicolor/256x256/apps/flutter.png if your desktop file has Icon=flutter. Which tool are you using that is saying "ERROR: Unable to load image."?

probonopd on 23 Apr 2020

Just launching the AppImage from the command line and then clicking on integrate and run. I guess that means it's running using appimaged?

jld3103 on 23 Apr 2020

Sounds a lot like https://github.com/TheAssassin/AppImageLauncher. cc @TheAssassin

@probonopd This document says that it needs be a symlink.

Changed, as I could not find anything in the ROX AppDir description that would indicate it needs to be a symlink.

probonopd on 23 Apr 2020

@probonopd This is the full application with the correct icon layout (now files but also tried with symlinks, but got the same result).
Now an icon is shown on the file and running once still works, but when trying to integrate it it fails with Segmentation fault (core dumped). Nothing more. I guess then it's not an appimage error rather than an appimagelauncher error, right?

@probonopd @jld3103 any updates?

marchellodev on 1 May 2020

I'm not sure how to proceed or even if the error I encounter is the same that you encouter

jld3103 on 1 May 2020

This is an AppDir, not an AppImage.

When I convert it to an AppImage like this:

wget -c https://github.com/$(wget -q https://github.com/probonopd/go-appimage/releases -O - | grep "appimagetool-.*-x86_64.AppImage" | head -n 1 | cut -d '"' -f 2)
chmod +x appimagetool-*.AppImage
ARCH=x86_64 VERSION=1 ./appimagetool-446-x86_64.AppImage ./hover-build-go_flutter_test-linux-appimage277435954

the AppImage works well on Xubuntu 18.04.4 LTS, and it has the correct icon when the optional appimaged daemon is used for desktop integration (rather than AppImageLauncher which I don't use) both in the file manager and in the menu:

icon

So I think the AppImage is fine as it is, for a final check please submit it to AppImageHub so that the automated tests can run. Thank you very much :+1:

If there are issues with AppImageLauncher please discuss them in https://github.com/TheAssassin/AppImageLauncher.

probonopd on 2 May 2020

Ok nice thanks. I'm not sure if I didn't read the documentation or if the documentation was wrong. Anyway I'm glad you helped me

jld3103 on 2 May 2020

@probonopd Now I used appimaged (also uninstalled appimagelauncher) and put the AppImage under $HOME/Applications and ran appimaged, but got this error message:

I'm using the normal appimagetool and not the go appimagetool. That shouldn't make a difference, right?

jld3103 on 2 May 2020

When using the go-appimagetool I get this:

jld3103 on 2 May 2020

I'm happy to look into this but please do open issues in the respective projects (the ones that crash) so that we don't mix up different things.

probonopd on 2 May 2020

I'm not sure if appimagelauncher and appimaged are the problems. Maybe it's just my wrong packaging?
I still have some things to try before opening a new issue.

jld3103 on 2 May 2020

Ok I'm getting some error logs. I'll try to fix them and hope that it works then. Let's see

jld3103 on 2 May 2020

But odd that the go-appimagetool reports misconfiguration while the normal appimagetool doesn't.

jld3103 on 2 May 2020

Still the same. No clue what to do now.

jld3103 on 2 May 2020

If you can write something down that I can reproduce I'll gladly help. (Especially since I am essentially moving everything to Go right now.)

probonopd on 2 May 2020

I'll try

jld3103 on 2 May 2020

@probonopd With that PR the tool generates the attached folder and the packages it. After copying the AppImage to ~/Applications and I run appimaged and get this error:

Can you reproduce it?
This is no information about the error, but I hope you can confirm that there is an error.

@marchellodev Can you try https://github.com/go-flutter-desktop/hover/pull/115 and submit the AppImage to try if the check still fails? (You have to clone the branch and do a go install. To go back just follow the install steps again)

jld3103 on 6 May 2020

@jld3103
https://travis-ci.org/github/AppImage/appimage.github.io/builds/684236478

marchellodev on 7 May 2020

I think is not the fault of go-flutter or hover.
./build/sharik: /lib/x86_64-linux-gnu/libm.so.6: version 'GLIBC_2.27' not found (required by ./build/sharik) indicates that there is something wrong with the glibc version

@probonopd With that PR the tool generates the attached folder and the packages it. After copying the AppImage to ~/Applications and I run appimaged and get this error:

From the message above, it looks like you are running into an issue in

appimaged, continuous build (commit b096cd3), build 221 built on 2020-03-30 19:16:46 UTC

Please report over at https://github.com/AppImage/appimaged/issues.

I am using https://github.com/probonopd/go-appimage/tree/master/src/appimaged instead and as written and shown in #5, it works well there. So it seems https://github.com/AppImage/appimaged has a bug which https://github.com/probonopd/go-appimage/tree/master/src/appimaged does not have.

This was built on Ubuntu 16.04 with @jld3103's pull request https://travis-ci.org/github/AppImage/appimage.github.io/builds/685028088

marchellodev on 9 May 2020

When trying to run it: Segmentation fault and that's it

marchellodev on 9 May 2020

That error is completely different from what this issue is about.
Can we close this when https://github.com/go-flutter-desktop/hover/pull/115 is merged and you open a new issue?

jld3103 on 9 May 2020

Ok, that's fine

marchellodev on 9 May 2020

Merged in https://github.com/go-flutter-desktop/hover/commit/b9d881be5eae011d61e3d6d2ed1e2830a9267b1f
It is not published yet, because there are going to be some changes, but if you want the fixed version you can clone the hover repo and do a go install.
I will closes this issue, because the original error is fixed.

jld3103 on 11 May 2020

If you do a go install, be sure to also locally create the docker image if you'd like to use --docker.

The easiest way to do that is to read and run install-with-docker-image.sh in the root of the repo.
