Installation and Deployment

I ran into this problem trying to compile ffmpeg with a QT dependancy.... to get past the not found I had to have a path to windows kit that held the fxc.exe file in my case C:\Program Files (x86)\Windows Kits\8.1\bin\x64. the cause seems to be in my case ? \qtdeclarative-git\plugins\scenegraph\d3....the make file has 26 shader header files it is trying to create with fxc.exe . Adding the path gets rid of the file not found BUT it does not get rid of the compile error the command in the make file does not execute correctly at this point it gives a too many files error . (I am still working on that part of it before I bug report it . This is assuming I am using the right fxc.exe and it can be run correctly from inside the build environment in my case mingwin. So if you have any feedback on how you got this working (IF) it would be appreciated here as well . I suspect that the make file has a TAB before the command that is causing the problem because if i cut and paste the commands with the tab i get errors but if i remove the tab it runs fine .

Hi and welcome to devnet, Check the archive here.

Hi, Pyinstaller might be an option.

Okay, whatever, I don't feel like arguing and we are going off topic here.

Hello, Thank you for your quick answer. I saw it but I wanted to test before answering. It works like you said. I had a doubt : as I used an "official installer" when I typed qtcreator and nothing happened I thought that something went wrong or that there was additional steps to finish the installation. All works fine. Thank you

@vinicius Hi, I solved this by using the cmd "D:\Qt\Qt5.8.0\5.8\mingw53_32\bin\windeployqt.exe test1.exe" it automatically copy all the dependent dlls to the folder. some of the dlls are not indicated by the error messages. But it just works

@Valera_QT said in Can't install Qt - connection refused during installation: I checked commercial - and no problems. Commercial downloads go through a different server by default. Open source users can pick a different server (mirror) too: https://wiki.qt.io/Online_Installer_4.x#Selecting_a_mirror_for_opensource

@Jonas-Tasng Switched to Linux mint. Problem solved !

Same issue on CentOS7: The user has to manually ldd /opt/qtcreator-4.10.2/lib/Qt/plugins/platforms/libqxcb.so then dig for each not found lib which package has to be installed: sudo yum install xcb-util-keysyms .... I would expect from QtCreator to at least properly warn the customer which libs are missing without having to export QT_DEBUG_PLUGINS=1

@deeskee said in Download Error. Hash verification while downloading failed. Please help: I'm having this exact issue. Pops up at 33%, then jumps back to 31% on "retry", repeat ad infinitum. Try downloading from a different mirror. Instructions at https://wiki.qt.io/Online_Installer_4.x#Selecting_a_mirror_for_opensource -- You'll need to call the installer from the Command Prompt.

@Nan-Feng said in About Qt 5.15 LTS Version ！: Is that right? Yes, (or better: No - they will be released to the non-commercial users in one year)

Thanks @jsulm , it's working now :-)

@J-Hilk Thank you , i will see it later and reply you as soon as possible when i try to doing it that it don't work

@AnneRanch said in All abou tQtCreator IDE , not about anyting else Qt - libray , installer , tool(s) . etc ...: What is (question) an official way to install QtCreator IDE ? Run the Online Installer: https://www.qt.io/download-qt-installer What is (question) the current official working version number of QtCreator IDE ? 4.14.1. (qustion ) Is current version of OtCreator IDE NUMBER SAME for windoze and Linux ? YES they are same numbers

It probably tries to write to /tmp/. Why are 119 GB required? Have you selected everything from the installer? Only select the parts of Qt you need and this number should go waaaay down.

@asmmoh said in qt creator cannot start the emulator: I cannot put the question in the two categories together and I need both of them. It's not the way how this forum work. I'm afraid you need to pick one category. And no, you don't need both of them. You just need one post, and hopefully other others helping you with answers.

Hi and welcome to devnet, Quoting myself: @SGaist said in Qt Creator extremely slow when adding large library INCLUDEPATH: Can you try with a more recent version ? Current is 4.2 Which may or may not apply to your case.

I feel so stupid. Thank you so much. I thought I downloaded the git branch for 5.15.2 but I hadn’t. I have just changed to Qt 6 and it installed perfectly.
