This used to work, but recently my system was updated. I run Gentoo with limited unmasking. Last time round this popped up, I downgraded Mesa, but this time round it is more difficult. The old versions of Mesa has been removed and trying to install the old versions result in a bees nest of dependencies that have received a similar fate. I built a simple Python test example using the code similar to what Cura uses and that runs without problems in a Python venv. Does someone here know what I could do to unravel this problem?

@martiniturbide in case you haven't yet encountered the following resources, they each list a number of Qt-based applications: https://wiki.manjaro.org/index.php/List_of_Qt_Applications https://forum.qt.io/topic/161772/recommendations-for-well-written-open-source-qml-projects-to-study https://forum.qt.io/topic/158013/what-s-the-most-beautiful-creative-interesting-software-made-with-qt-you-ve-seen

Hi there, I am facing the same problem. Did you make any progress, or does anyone have some new input on this topic ? Thanks.

@HarryGoddardTech said in Invalid metadata: I'm getting the following error when I run "Squish for Qt 9.0.0" Please clarify what you mean by this. For example, Do you get the error when launching the Squish IDE? or During the execution of the already existing test suite? It might be worth checking the "System Level" and/or "User Level" PATH environment variable to confirm no Qt related path is included.

I already wrote to this e-mail by using the built-in function from youtestme - no answer yet. The result from the test is already there I am just waiting for the proctoring report. [image: 64449ca2-2b0f-4143-886d-e822cda62e62.png]

Hi, I think you went the too complicated road: quint16 calculateCrc16Arc(const QByteArray &data) { quint16 crc = 0x0000; const quint16 poly = 0xA001; for (char byte : data) { crc ^= (static_cast<quint8>(byte)); for (int i = 0; i < 8; i++) { crc = (crc & 0x0001) > 0 ? (crc >> 1) ^ poly : (crc >> 1); } } return crc; }

请问我的QT程序是关于连接远程数据库的，打包给其他的没有qt和数据库环境的电脑去连接数据库是可以的，但是放到同样的没有qt和数据库环境的机器配套的电脑连接远程数据库就显示driver not load，这个是因为什么，我个人的猜想是会不会是因为机器的电脑只有机器的配套软件而没有某些环境导致的？

Hi @RokeJulianLockhart, just some additional thoughts to consider... Kubuntu is an official "flavor" of Ubuntu. That is, its supported by Ubunutu, and has the same LTS and non-LTS releases Ubuntu has. KDE Neon is based-on an LTS Ubuntu, but is not supported by Ubuntu. It contains more recent KDE components, and is maintained (not sure about supported) by KDE devs. So there's definitely pro's and con's to both. But I'm sure both are good either way. I ask about Kubuntu explicitly because it's Qt-based, being the KDE Plasma variant, so I prefer it for verifying Qt bugs. While KDE is Qt-based, it actually uses Qt-derived libs, rather than Qt per se. So while it really doesn't matter, if you really like to use Qt on Ubuntu (as I do), then I can recommend Lubuntu, which is also an official Ubuntu flavour (supported by Ubuntu), but using the LXQt desktop by default instead. LXQt is a lightweight Qt-based desktop environment, so much more Qt-pure than KDE is (though again, it really doesn't matter). It's certainly not as feature rich as KDE, but then its without KDE's bloat too. LXQt suits my needs perfectly (by largely staying out of my way), but of course might not be right for you. Worth knowing about anyway. Cheers.
