I am not shure if this bug is already reported.
A seach in the bugtracker doesn't return a result, but I may have used the wrong search term, so I first will explain it here and hope for guidelines how to proceed.
I tried to make the help files (FreeCAD.0_18.Offline.Doc.7z) available from inside "FreeCAD_0.18.16093.glibc2.17-x86_64.AppImage".
For this I extract the AppImage, add the help files to the created AppDir (AppImage term), then repack...
After this the Error-Message given when clicking Help/Help changes from:
FreeCAD help files not found (/tmp/.mount_FreeCAkLtzzg/usr/lib/freecad-daily/././/share/doc/freecad-daily-doc/freecad.qhc). You might need to install the FreeCAD documentation package.
Unable to launch Qt Assistant (/tmp/.mount_FreeCAE51EtB/usr/lib/freecad-daily/bin/lib/x86_64-linux-gnu/qt4/bin/assistant)
a quick search where the orignal assistant is located on a regular qt4 installation shows, that is located at
And Yes, this is although the place it is inside AppDir.
So it seams that the path that is compiled in or calculted inside the runtime is wrong.
But even when I add a symlink like this:
APPIMGDIR=<Full Path of extracted AppDir 'squashfs-root'>
ln -s ../../../../usr/lib lib
check (should work):
The result is still not the one expected. Now when clickng Help->Help nothing happens
No Error-Message, no output on the console...
Now I am out of ideas
