AppImage file not generated?

[gaojinhsu]

I created a simple demo project based on Qt6.3.1 on ubuntu20.04, and created a directory tree manually like this

    ├── bin
    │   └── untitled
    ├── lib
    └── share
        ├── applications
        │   └── untitled.desktop
        └── icons
            └── hicolor
                └── 256x256
                    └── apps 
                        └── logo.png 

my .desktop file was like

[Desktop Entry]
Type=Application
Name=Amazing Qt App
Comment=The best Qt Application Ever
Exec=../../bin/untitled
Icon=../icons/hicolor/256x256/apps/logo
Categories=Office;

after that , I used linuxdeployqt like this
linuxdeployqt ./Untitled/usr/share/applications/untitled.desktop -verbose=2
As a result, some files was generated, and some Qt libs were copied into the usr/lib directory.

├──AppRun
├──untitled.desktop
└── usr
    ├── bin
    │   └── untitled
    │   └── qt.conf
    ├── lib
    │   └── libicudata.so.56
    │   └── libicui18n.so.56
    │   └── libicuuc.so.56
    │   └── libQt6Core.so.6f
    │   └── libQt6DBus.so.6
    │   └── libQt6Gui.so.6
    │   └── libQt6Widgets.so.6
    └── share
        ├── applications
        │   └── untitled.desktop
        └── icons
            └── hicolor
               └── 256x256
                   └── apps 
                        └── logo.png 

I could run AppRun in terminal（with a warning, libEGL warning: pci id for fd 26: 1ab8:0010, driver (null)

pci id for fd 27: 1ab8:0010, driver (null)), but nothing happened with double-clicking, Also I didn't see any files with suffix of .AppImage was generated. the whole bundle still looked like an ordinary directory but an executable one.

here is the log.

So far I have never touched Qt 6 yet. linuxdeployqt most likely can't handle it properly?

[gaojinhsu]

No，it can’t. I have tried it on Ubuntu 18.04 with Qt5.9（why 5.9？ here is the reason), it works well. I really hope it can support Qt6. because some critical bugs have been fixed in the latest version. Besides, a lot of new APIs have been included, especially in QtWebEngihe module.

[a12e]

Qt 6 support is on its way to be merged, see #495 and #541

[mgautierfr]

I've faced the same issue (with qt5). From strace, the last linuxdeployqt action was a access to AppDir/usr/share/doc/libc6/copyright

...
stat("/home/****/*****/AppDir/usr/share/doc/libc6/copyright", 0x7ffd0e0c9be0) = -1 ENOENT (Aucun fichier ou dossier de ce type)
exit_group(1)

mkdir -p AppDir/usr/share/doc/libc6
touch AppDir/usr/share/doc/libc6/copyright

solves the problem

[probonopd]

The question is, why doesn't linuxdeployqt deploy that file automatically...

[yh-sb]

Same issue with linuxdeployqt (commit e83eeb7), build 53 built on 2023-08-28 23:47:07 UTC

Workaround is touch AppDir/usr/share/doc/libc6/copyright
