No worries. I'll move the whole thing to a repo and post the link here. Installation instructions will be provided in the repo.

sorry dont want to sound like an idiot but any instructions? PLEASE?

I've moved the entire thing into a Git repository complete with a .deb you can download and install.

---> https://github.com/EvilSupahFly/QNAP-Qfinder-Fix/releases/tag/7.12.3.0527

Very Awesome! thank you so much. been waiting for qnap to fix this forever.

interestingly it installed ok but when i try to run it i get this: also i am on LMDE6 so that might be why. ill try it on my mint machine in the am. and will let you know. and thanks again!

The QNAP app stores all its libraries in /usr/local/lib/QNAP/QfinderPro and they're built against QT5, which you should have installed. Also, because you're on LMDE, your libc might be too old since QNAP prefers (or expects) the upstream Ubuntu libraries. I'm running Mint 22.1 Cinnamon. I suggest checking your libc version like so:

$ ldd --version

On my system, I get this:

ldd (Ubuntu GLIBC 2.39-0ubuntu8.4) 2.39

If your libc is the issue, I'll have to make a fix for the older version too. According to the release notes on QNAP's website, you need something based on Ubuntu 18.04 minimum, which means you should be running libc 2.27 at minimum.

There is a point of interest in your log:

QObject::connect: No such signal QfinderTableView::columnSizeChanged()
QObject::connect: No such slot ICloudHttpRequestBase::onSslError(QNetworkReply*, QList)

This suggests runtime linkage or ABI mismatch problems within the Qt5 library. This could be caused by:

• Using a Qt5 version that's older than the one Qfinder Pro was compiled against.
• Mismatch in qtbase5, qttools5, or related dev packages (e.g., libqt5core5a, libqt5network5, etc.).

So, the app might install fine (like you've experienced), but dynamic linking at runtime can still fail if it can't resolve expected signals or slots, which is what you MIGHT be seeing.

To see what QNAP is looking for, you can run this in your terminal:

ldd /usr/local/bin/QNAP/QfinderPro/QfinderPro

Once you have them, post the results here. From what I have been able to determine, QNAP bundles most of its own Qt5 libraries in /usr/local/lib/QNAP/QfinderPro/, but some dependencies (like /lib/x86_64-linux-gnu/libQt5Sql.so.5 and /lib/x86_64-linux-gnu/libQt5Svg.so.5) are being resolved from the system.

So you're potentially either missing QT5 dependencies, or there's a version mismatch because LMDE prioritizes stability, so rather than being on the bleeding edge, they usually run several major versions behind, so I'll need to see your full OS specs to be sure (your libc version, your QT5 version, and what version of LMDE you're running).

@david85091 I've opened an issue at EvilSupahFly/QNAP-Qfinder-Fix#1 so this can be tracked as part of the project since QNAP's dev team will likely be reviewing things over there.

Once you've had a chance to test my suggestions, and you have all the output, post your reply to the ticket I created and we'll pick things up over there.
