 |
|
Hello,
now especially in CORONA-/COVID-19-times there's a special need for video-conferencing-tools but not everyone / every organization are willing to use tools that are free - and therefore I'm forced to have zoom on my machines (unless I'd like to stay connected via telephone without being able to watch necessary presentations...). On my ~amd64 desktop I took ebuilds from overlays until it made its way into the main tree. By that time I saw this ebuild was also ~x86 so I took my chance to have it on my 32bit-laptop. Installation went fine but I can't start it. On the command-line it complains:
| Code: | andy@pulp-fiction /home/andy $ zoom
./zoom: error while loading shared libraries: libQt5WebKitWidgets.so.5: cannot open shared object file: No such file or directory |
That's correct in the way that it can't find 'libQt5WebKitWidgets.so.5' 'cause dev-qt/qtwebkit is not on the laptop.
My first impulse was to emerge it but then I had a look at the ebuild and compare the whole issue with my ~amd64 using scanelf.
These are the results:
~amd64:
| Code: | kill-bill /home/andy # scanelf -n /opt/zoom/zoom

So on the ~amd64 it uses qtwebengine whereas on the ~x86 it wants qtwebkit.
(qtwebengine is on both machines, qtwebkit only on the ~amd64)
Does anyone have a clue why it behaves like this?
Greetings,
Andy

Hello,
I investigated by unpacking the x86_64 and i686 client tarballs from Zoom's download page.
The x86_64 tree includes a binary of libQt5WebEngine.so.5.9.6, whereas the i686 tree includes a binary of libQt5WebKit.so.5.5.1 among other Qt5 binaries in both trees.
Hope this helps! |

The simple explanation is that qtwebengine is becoming impossible to compile on x86 due to its bloat.
The alternative to using qtwebkit is to have no x86 version at all, something that most other proprietary web-browser IM programs already do. |

| I doubt that is an issue this proprietary software is really having trouble with. More likely they are not doing anything to their codebase for x86 anymore except for keeping up with their compatibility needs. |

OK, then there's just missing dependencies for ~x86 in the ebuild. I'll emerge qtwebkit and look what happens when it's present on the little one.
(Last time I emerged it on the ~x86 it took nearly 8 hours. That was September/October 2018. And I bet compile-times have increased since then - even for qtwebkit  )

Now qtwebkit is on the ~x86 and zoom works as expected.
Should I open a bug?

| Tip: Install zoom with flatpak. Works fine, and you don't need to handle dependency hell. |

Of course, a missing dependency is a bug. |

Done that:

Thanks a lot for your help!
