Installation and Deployment

Hi and welcome to devnet, This rather looks like an online installation. As the error message suggests, try a different mirror.

@Fares-Haoua said in Invalid Link: i wanted to download it Download what? educational account Is it verified already?! "link expired" window popped what should i do ? Try to resend the link or contact the Qt Company.

@Pierre-Emmanuel said in Qt 64 bits application: Maybe or maybe not ? Not "maybe". Creator (nor Qt itself) has nothing to do with runtime searching for libraries/DLLs for an executable. That is done by the OS/Windows, and that requires them to be found on either PATH or in the same directory as the executable. This would also be the case if you ran your program quite outside of Creator. No OS searches PATH recursively (would be too slow and too dangerous). So something has changed between your Qt5/6 or its environment.

@Robert-Harakaly said in Fetch problem with commercial boot2qt build: The opensource version builds, thus the problem is in the commercial license configuration. Then you should probably The Qt Company about this. At least if you don't get an answer here.

OK that was the problem! I think it would be more helpful if selecting archive automatically updated the list of available releases!

I am having similar issues but removing the licence file did not work for me. Can someone guide me.

working code for Windows user in command prompt : C:\Users\UserName\Downloads\qt-online-installer-windows-x64-4.8.1.exe --mirror http://qt.mirror.constant.com

@salirezag After (trying to) run from it Windows File Manager run up Task Manager and see whether the process for the executable is still running. Either it is, in which case for some reason it is not showing any interface, or it is not, in which case either it never ran (and Windows did not give you an error message for some reason) or it ran and exited. Try running the executable from a Command Prompt. You may get some information there as to whether it runs, when it exits or some helpful message.

Hi, You should go to the bug report system and check if there's already something about this issue. If not, please open a new ticket about that matter.

Hi, The SSL issue is a problem of the mirror administrators so nothing the Qt Company can act on beside notifying them that there is an issue. For the missing mirror list, you should open an issue on the bug tracker. For the offline installer, it's available to the commercial license holders.

Thanks for the info!

That error with 'type_traits' usually occurs when you have a mismatch between the compiler version (Visual Studio 17) and the Qt version you're building. Lots of google hits on this, for example here

@Charac i have resolved this，though i do not know how it does work, but it do work for me. follow this steps: 1.打开命令提示符（以管理员权限）。(open the command prop as admin) 2.运行以下命令从 Windows Update 获取最新的根证书列表。（run the command to update your root certs） certutil.exe -generateSSTFromWU roots.sst 3.将生成的 roots.sst 文件导入到受信任的根证书存储中。（import the result to the trusted root certs） Import-Certificate -CertStoreLocation Cert:\LocalMachine\Root -FilePath .\roots.sst

I'm having a similar issue while building Qt for Windows (qt.qt6.681.win64_msvc2022_64). My concern is, even if the install completes there's no way for me to exhaustively verify it's correct, its alarming to see so many "Warnings". Also is there any way to filter the package further? I'm building this for a CI/CD system and don't need QtCreator and many of the other tools. I'm looking for a solution that is "faster" than building from the source files.

I tried the -device parameter, but I'm not sure how to use it. The parameter value seems to correspond to files in mkspecs/devices/ but I can't see any entry there explicitly for x86, so I tried "-device linux-generic-g++" but it still fails with the same problem I mentioned earlier. I also tried with "-device linux-nuc-g++" (figuring that's similar to the actual target), still no luck.
