Installation and Deployment

@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.

After the advice from @SGaist I started to experiment a bit with settings of the build steps: problem disappeared after I did these three steps one by one (after each I checked if the problem is gone - it disappeared after the last step: turning off QML debugging and profiling switch (default was "leave default", effective call showed CONFIG+=qml_debug now it is CONFIG-=) turning off QtQuick compiler (default was "leave default, effective call showed CONFIG+=qtquickcompiler now it is CONFIG-=) deleting shadow build folders (I do it routinely once a week or so anyway). Now the problem is gone, I am marking the topic as "solved".

So I finally found an answer. You simply uncheck and hit next and then update. It would be nice if there was a better confirmation message that states exactly what is about to be done. The predicted disk usage is a bit lame.

@san_qt_enthusisast I guess you should be using Java 8

FWIW, it seems to work fine in Win10 and IFW 4.0.0 these days, even when the string contains spaces (i.e. installed in c:\program files...).

@jsulm no problem, I was hoping that wouldn't be the case! Thanks again for the help.
