Unable to download and install QT

Parthasaradhi · 21 Oct 2019, 02:19

Hi all,
I had installed QT and was testing out some code. My friend sent one sample code he developed and when I tried to compile that code, I was prompted to install a newer version. While downloading the newer version there was an error message and my original installed version also got corrupted. I am now trying to download QT again but I am not able to. When I try to download, I see the auto-filled form (as I am already registered user) and when I submit, nothing happens. How can download and install QT creator? Please help. Also, I have GCC already installed on my system, so do I still need to download GCC along with QT (not sure if QT creator comes bundled with GCC), if not how can I configure QT creator to use/see the installed GCC? Thanks in advance form your time.

Hi
GCC is not included. it will use the system installed.
Qt is the name of the framework.
Qt Creator is the name of the IDE/Editor that can work with multiple version of the Qt framework.

Creator is included in Qt installation.

Try the offline version then

What was the error message?

What was your original version?

How did you install your original version?

I have GCC already installed on my system

Which version?

What is your OS?

how can I configure QT creator to use/see the installed GCC?

First, add your compiler: https://doc.qt.io/qtcreator/creator-tool-chains.html
Then, add your kit: https://doc.qt.io/qtcreator/creator-targets.html

That's OK. What about my other questions?

Anyway, pay attention to error messages because they can contain useful information that helps you to fix the problem.

@mrjj
Thank you for your reply. I downloaded and installed QT, but there is some issue. Kindly see below
@JKSH
The version was IIRC 4.9.

I downloaded the newer version and installed it. When I try to open an earlier project(s), I am being prompted to configure the project. Attached the screenshot for your perusal. I have GCC installed on the system but not able to configure the project. Kindly help me configure the project, please.

Hi
You seem to have installed the Qt visual studio edition.
(MSVC)

You need to download and install the compiler from microsoft.
Its not included as thats forbidden.

The MinGW version has a compiler and debugger included.

So Make sure you ONLY install the Qt where you have compiler installed.
If you really dont care and all you want is to use Qt to make Desktop apps
then only install the mingw version and nothing else.
Installing ALL takes up lots of space and give more room ffor issues.

Hi mrjj,
Thank you very much for your reply. I uninstalled Qt. While installing Qt afresh, how do I exclude GCC? Thank you once again.

Best regards

Just make sure it is not selected in the installer...
But keep in mind that for MSVC you need to install Visual Studio by yourself first.

@jsulm Thank you very much for your reply. However, I did not see this option when I tried to install Qt. I will check once again. Maybe I missed seeing theoption. I will try again.

Best regards

@Parthasaradhi You will not find MSVC itself in Qt installer as it is not allowed by Microsoft. You need to download MSVC from microsoft and install it. Then install Qt for MSVC using Qt online installer.
