AppImage support

[mantielero]

Distributing the application as an AppImage can make easier the installation/execution under much more Linux Distributions.

[AlbrechtL]

I added it to the task list. However, somebody has to take the job. Are you interested in creating one?

[mantielero]

I've been trying but I'm not managing to do so. (First time I try to build an AppImage and I don't know much about qtcreator/qt programming).
I have manage to compile welle and run it. But when I run:

$ linuxdeployqt-continuous-x86_64.AppImage ./welle-io
Not using FHS-like mode
app-binary: "/tmp/build-welle.io-Desktop-Release/welle-io"
appDirPath: "/tmp/build-welle.io-Desktop-Release"
relativeBinPath: "welle-io"
ERROR: Bundling Qt provided by distributions is not yet supported by this tool.
ERROR: Please see https://github.com/probonopd/linuxdeployqt/issues/79 and
ERROR: submit a Pull Request to implement this.
ERROR: In the meantime, use Qt from the Qt Company
ERROR: or Qt for /opt from https://launchpad.net/~beineri

I don't know how to properly setup Qt for this to work.

Besides I have checked that I don't get any DAB+ station where I live, so I have lost a lot of motivation.

Sorry

[tnadolecki]

Would a RAW file motivate you ?

[probonopd]

I don't know how to properly setup Qt for this to work.

On Ubuntu 14.04 (e.g., on Travis CI), run:

sudo add-apt-repository ppa:beineri/opt-qt58-trusty -y
sudo apt-get update -qq
sudo apt-get -y install qt58base
source /opt/qt58/bin/qt58-env.sh

Here is a full example for an other Qt-based application:

I am trying to build an AppImage on Ubuntu 14.04 on Travis CI but I am running into

Here is my preliminary .travis.yml but it still suffers from the above:
https://github.com/probonopd/welle.io/blob/patch-1/.travis.yml

And here are the build logs:

@AlbrechtL can you give me step-by-step instructions how to compile this on Ubuntu 14.04 please? Then I can do an AppImage.

[AlbrechtL]

Please use the Ubuntu 16.04 how to and adapt it to 14.04.

[probonopd]

That's what I did, here.

[AlbrechtL]

Can you provide a welle.io AppImage to test it?

[probonopd]

No, because compilation fails with this error.

[AlbrechtL]

If you change

 int16_t Data [fragmentSize] = {0};
 int16_t tempX [fragmentSize] = {0};

to

 int16_t Data [fragmentSize] ;
 int16_t tempX [fragmentSize];

it should work.

[probonopd]

Thanks, how can I disable airspy at build time without editing the .pro file?

[AlbrechtL]

I don't know. You can check the qmake docu or you write a small script that edits the .pro file before the build starts.
Another option is to include the airspy driver to the image.

[probonopd]

Doing that now. Thanks

[probonopd]

The command sudo make INSTALL_ROOT=appdir install fails, do you have an idea why; or what I could do?

[probonopd]

Turns out make install does not work at all

[probonopd]

I think this can be closed now, as an AppImage gets built on each git push now. The download link is in the Travis CI build log.

Something like https://github.com/probonopd/uploadtool could be used to upload the builds to GitHub Releases.

[AlbrechtL]

Thank you very much for the AppImage support!
