Please provide AppImage for download on GitHub Releases

[probonopd]

You can also prepare your own AppImage for Linux as described in https://github.com/mki1967/mki3dgame/blob/master/appImage-instructions.txt

Please provide an AppImage for download on GitHub Releases. You can use Travis CI to automate this.

Doing so would make it possible to include it in the AppImageHub central directory of available AppImages.

Here is an overview of projects that are already distributing upstream-provided, official AppImages.

If you have questions, AppImage developers are on #AppImage on irc.freenode.net.

[mki1967]

@probonopd I am preparing AppImage for each release by running the script: https://github.com/mki1967/mki3dgame/blob/master/make-AppImage.bash in the main directory, and then I upload it as attached binaries to the release creation page: https://github.com/mki1967/mki3dgame/releases/new

For example, the AppImage for the most recent release is available at: https://github.com/mki1967/mki3dgame/releases/download/v1.9/mki3dgame-x86_64.AppImage

Is there any other place, where I should upload the file?

[probonopd]

Must have overlooked it. Thank you very much!

[probonopd]

Strangely getting this message:

Reference: https://github.com/AppImage/appimage.github.io/pull/154

Not sure what causes this, though.

[mki1967]

I was testing the AppImage on desktops and laptops with Ubuntu 16.04 LTS and on Manjaro that I have on my protable disk. I could not reproduce this error. Was this error on some older version of the Linux system?

The panic seems to be raised when the GLFW window is created: 112 window, err := glfw.CreateWindow(windowWidth, windowHeight, "Mki3dgame", nil, nil) 113 if err != nil { 114 panic(err) 115 }

However, your message helped me to notice that I have somehow accidentally reinstalled and used the older version of Go -- the one from distribution :-/

I have now prepared the AppImage compiled again with: go version go1.8.3 linux/amd64 https://github.com/mki1967/mki3dgame/releases/download/v1.9.2/mki3dgame-x86_64.AppImage

[probonopd]

Yes, I am using the oldest still-supported LTS release which is 14.04 at this point.

[mki1967]

I do not have access to Ubuntu 14.04 at this moment. I am using the OpenGL version 3.3 which is the oldest worth to be used according to: https://learnopengl.com/#!Getting-started/OpenGL Maybe the required profile is not available on Ubuntu 14.04?

107         glfw.WindowHint(glfw.ContextVersionMajor, 3)
108         glfw.WindowHint(glfw.ContextVersionMinor, 3)
109         glfw.WindowHint(glfw.OpenGLProfile, glfw.OpenGLCoreProfile)
110         glfw.WindowHint(glfw.OpenGLForwardCompatible, glfw.True)
111         glfw.WindowHint(glfw.Samples, 4) // try multisampling for better quality ...
112         window, err := glfw.CreateWindow(windowWidth, windowHeight, "Mki3dgame", nil, nil)
113         if err != nil {
114                 panic(err)
115         }

[probonopd]

Quite possibly.

[mki1967]

@probonopd I have commented out the line with the GLFW hint for Forward Compatibility: 110 // glfw.WindowHint(glfw.OpenGLForwardCompatible, glfw.True) I have made a new release https://github.com/mki1967/mki3dgame/releases/tag/v1.9.3 with this AppImage: https://github.com/mki1967/mki3dgame/releases/download/v1.9.3/mki3dgame-x86_64.AppImage

I have tested that this AppImage still works on Ubuntu 16.04 and on Manjaro and I hope it should also work on Ubuntu 14.04 (since the error message on the picture mentioned 'Forward compatibility')

[probonopd]

Now getting

But this may be due to the fact that there is no proper OpenGL on my test setup.

[mki1967]

Maybe I should install Ubuntu 14.04 on some USB stick ... I have just started downloading: http://releases.ubuntu.com/14.04/ubuntu-14.04.5-desktop-amd64.iso.torrent?_ga=2.258831938.959726710.1510128452-1353750228.1508527019 form the page: https://www.ubuntu.com/download/alternative-downloads

I hope it is the proper version?

[mki1967]

I have started the downloaded Ubunu 14.04.5 in VirtualBox, then I have downloaded the AppImage: https://github.com/mki1967/mki3dgame/releases/download/v1.9.3/mki3dgame-x86_64.AppImage And it works!

Now I have no idea what should I do ...

[probonopd]

Thank you very much. So it indeed seems to be an issue of my automated test setup. Sorry for having created noise here.

[mki1967]

@probonopd I have just started to use (and to learn) Travis today.

Without much understanding, I have used slightly modified version of https://github.com/go-gl/example/blob/master/.travis.yml in mki3dgame as
https://github.com/mki1967/mki3dgame/blob/master/.travis.yml and the build passed.

Maybe the following fragment is a hint for the needed setup:

addons:
  apt_packages:
    - libgl1-mesa-dev
    - xorg-dev

[probonopd]

You mean, for the build or for running the test @mki1967?

[mki1967]

The '-dev' libs are for build. Three related runtime code should be in standard desktop environment. The appimage from my releases run on the desktops that's I have tested.

[probonopd]

OK, so the only question then is why are we seeing this error on the machine that does the automated reviews and screenshots. If I merge this as-is, then the ugly error will be on the screenshot on AppImageHub, which is not desirable. Would you consider adding an AppStream file including a link to a pretty screenshot? Thanks.

Here is an AppStream assistant that should make it easy: http://output.jsbin.com/qoqukof

[mki1967]

Ok. I will try to work on it.

[mki1967]

@probonopd

I have prepared the file usr/share/metainfo/mki3dgame.appdata.xml with the page and now I get the following strange error, while building the AppImage with appimagetool-x86_64.AppImage:

I have pushed the (culprit?) file to master branch: mki3dgame.appdata.xml

The previous version did not cause such problem.

[probonopd]

Interesting @mki1967. So appstreamcli is crashing?

This is what I am getting on Deepin Linux:

@ximion: I'm pretty sure I didn't invent the tag 'launchable'...

[ximion]

@probonopd You didn't - what's the version of AppStream you use to validate this? appstreamcli --version should ideally return something like AppStream version: 0.11.8

[probonopd]

appstreamcli --version
AppStream CLI tool version: 0.11.2

That is the latest version in my distribution, deepin-15.5-amd64.iso. You see, we need a way to bring the latest version to people (static build, AppImage, web service, whatever...)

[ximion]

Heh, yeah, the smallest version you would need for this to validate properly is 0.11.3 (released beginning of last August).

[mki1967]

The version of appstreamcli on my Ubuntu 16.04 is:

$ appstreamcli --version
AppStream CLI tool version: 0.9.4

Maybe the most recent version of appstreamcli could be bundled to appimagetool-x86_64.AppImage ?

[probonopd]

It has been an ongoing systematic ongoing annoyance that it is hard to run the latest appstreamcli on the oldest still-supported LTS releases of distributions (the ones we recommend for compiling applications on, to get binary compatibility with older systems).

We have a more recent version of appstreamcli at https://github.com/AppImage/appimage.github.io/releases/download/deps/appstreamcli-x86_64.AppImage - would this work for you?

[mki1967]

I have build the last mki3dgame-x86_64.AppImage with the recent appimagetool-x86_64.AppImage on Ubuntu 18.04 and it seems to be ok. Even the icon is being displayed while the program is running ;-)

I have noticed that the file: https://github.com/AppImage/appimage.github.io/blob/master/database/mki3dgame/mki3dgame.appdata.xml is from 7 Nov 2017. The current version is: https://github.com/mki1967/mki3dgame/blob/master/usr/share/metainfo/io.github.mki1967.mki3dgame.appdata.xml
