Description Nicofo 2022-11-06 13:10:19 UTC

+++ This bug was initially created as a clone of Bug #461469 +++

The 'Help' window does not work (empty window with message "Cannot load page https://docs.kde.org/?application=digikam&branch=trunk5" ;that message appears after a progess bar going to "100%"): see screenshot https://bugs.kde.org/attachment.cgi?id=153498

Note: that help window can be called from several places:
 - Help > Online Handbook...
 - Settings > Configure Digikam > Help button at the bottom left

Maybe is this bug specific to appimage ? (I use appimage on Fedora 35)

Comment 1 Maik Qualmann 2022-11-06 15:23:45 UTC

QWebEngine in the current AppImage seems to be broken. The local welcome page does not load either.

Comment 2 caulier.gilles 2022-11-06 16:01:34 UTC

Maik,

I currently recompile AppImage from scratch using xubuntu as host instead Mageia and with last Qt 5.15.7. We will see if this solve this issue.

Comment 3 caulier.gilles 2022-11-08 07:01:47 UTC

Hi Maik,

I finalized the port of scripts to compile the AppImage under Ubuntu 18.04 instead Mageia7.
It still a little problem to upload files in KDE server. I will fix that today.

Comment 4 Nicofo 2022-11-08 19:25:14 UTC

I tried with digiKam-7.9.0-20221108T161738-x86-64.appimage 
Unfortunately it does not work under Fedora:

digikam: error while loading shared libraries: libpcre.so.3: cannot open shared object file: No such file or directory

(on my system, I have only /usr/lib or lib64/libpcre.so.1)

Comment 5 Nicofo 2022-11-08 19:32:20 UTC

Note: I have a "libpcre.so.3" file coming from Steam runtime. I have tried to preload it with for the sake of the test:
LD_PRELOAD=/home/<user>/.local/share/Steam/ubuntu12_32/steam-runtime/lib/x86_64-linux-gnu/libpcre.so.3

-> digikam starts, and, good news, the problem of Help window is solved ;-)
Thanks.
So, this bug can be closed.

But there remains a problem with the new appimage on Fedora. I don't know if it is possible to include "libpcre.so.3" inside the appimage (and if it is the proper way to solve this issue).
Do you want me to open a new bug report for that ?

Comment 6 caulier.gilles 2022-11-09 05:08:40 UTC

yes the original problem with online doc is fixed.

For the preloading of libpcre.so.3 if will fix this.
