This package is now working. Thanks a lot. The only missing dependency for me was the AUR-package openssl-1.1

Thank you wowotiel. This is not expected with the zlib package. I've fixed that with pkgrel=5. If you had zlib instead of zlib-ng-compat, it will be used. Concerning gdb, I only know it can be used for debugging. There are guides online about how to use it. Best of luck!

Version 4 does not work either. I still get the segmentation fault. Ps zlib was removed and instead installed zlib-ng-compat. dbg is for me to difficult. I tried it but get the message: No debugging symbols found in QfinderPro.

Sorry for the delay. I've resolved the dependencies with pkgrel=4. If you still have a segmentation fault (Segmentatiefout), I would suggest either debugging with gdb, but this may not be for everyone. Is your locale properly configured? (https://wiki.archlinux.org/title/Locale#LANGUAGE:_fallback_locales) Keep in mind I am not affiliated with QNAP, and I provide access to their official package as is. Keep posting your issues in the event I happen to be more useful!

Same unfortunately. :( Really weird. Is there a way to get some more extended logs somewhere? Sorry I am new to the Linux World.

With pkgrel=2 I still get no working Qfinder Pro.

My output is:

    libdhnetsdk.so => not found

/usr/lib/libcrypto.so.1.1 is provided by the package openssl-1.1, and this shows you already have it. And unfortunately, I don't know what the issue could be. Still, I just noticed the libraries shipped with the original package aren't properly installed. I've fixed that in the new commit. Try it out!

I assume I need to install libcrypto.so.1.1 => /usr/lib/libcrypto.so.1.1

manually?

I may not have included the necessary dependencies. I cannot test this on my own until next week. For debugging the issue, can you return the result of this command? ldd /opt/QNAP/QfinderPro/QfinderPro | grep "not found" You will have to change the "not found" part for your system language. Here's an example on my system by running only ldd /opt/QNAP/QfinderPro/QfinderPro

libQServerIconLib.so.1 => not found
libcrypto.so.1.1 => /usr/lib/libcrypto.so.1.1

Wild guess, you may have to install this package: qt5-base
