Qt Creator IDE: how to download x64 version?

@fem_dev said in Qt Creator IDE: how to download x64 version?:

It shows me that my Qt Creator IDE is a 32 bit application. Right?

Right, the Qt website lets you download the 32-bit IDE.

I don't understand this, because I'm using Windows x64 and I downloaded the Qt setup from the offical web site:
Why this setup give me the 32 bits application and not the x64 Qt Creator application?

Because 64-bit Windows can run 32-bit applications with no problems at all. Also, there is very little benefit to using a 64-bit IDE.

You don't need a 64-bit IDE. You can use your 32-bit IDE to build 64-bit programs (as long as you have 64-bit libraries and 64-bit compilers)

How can get the x64 version of Qt Creator IDE?

If you really want a 64-bit IDE, you can build it from the source code yourself using your 64-bit compiler and 64-bit Qt libraries: https://code.qt.io/cgit/qt-creator/qt-creator.git/tree/

EDIT: You can also download the 64-bit IDE from https://download.qt.io/official_releases/qtcreator/4.10/4.10.0. Thanks, @aha_1980!

Other question:
Why Qt Creator IDE shows me the "MSVC 2017"? I have a Microsoft Visual Studio 2019 Enterprise installed on my machine.

This information tells you that the Qt Creator application was built using 32-bit MSVC 2017, linked to 32-bit Qt 5.13.1.

This is completely unrelated to the compiler that you use to build your own projects.

@jksh perfect answer! Thank you!

Hi @fem_dev,

FYI: There are x64 builds, but standalone: https://download.qt.io/official_releases/qtcreator/4.10/4.10.0

No idea why they are not integrated in the online installer.

Regards

Huh, TIL!

@aha_1980 To use the x64 version I uninstalled my Qt Creator 4.10 (32 bits), downloaded and installed the x64 version.

But this x64 setup not install qmake and it has only 600MB...
During the install process I don't see any options to install "ARM" or "Android" packages too...

Its right?

Yes it is. As @aha_1980 mentioned, it's a standalone Qt Creator installer.

You can't do that, unfortunately.

With the official Qt installer, you must to install the 32-bit IDE together with the libraries.

The IDE is not the library.

These are all libraries.

What problem are you actually trying to solve? Why is it so important to you to have an x64 copy of Qt Creator, and to remove the 32 bit version?

Qt Creator is just a glorified text editor. Having a 32 bit IDE doesn't effect your ability to build 64 bit apps with it. It will happily run whatever compilers you have installed, regardless of how it was built. It sounds like you are putting in a lot of work trying to fix something that wasn't broken.

@wrosecrans thank you! You are 100% right!

Why use the x64 build of Qt Creator you ask? I can answer that base on my experience, working on a faily large QML / C++ mixed project. The 32-bit version that comes with the online installer crashes at least once a day on me due to running out of user space memory. It is not even built with /largeaddressaware, so it will start to fail at around 1.2GB of RAM usage.
Some would argue that such a "glorified text editor" is using too much RAM then. Well, it is obviously more than just a notepad, and also, I don't care. I would argue that a stable IDE & Debugger that is capable of using available system resources when required is more important than some outdated notion about what you should and should not need.
Anyway, thanks for the download link. That was exactly what I was looking for.

Hi
Did you notice any speed improvements?
I know its not a given thing but just wondered.

Just a note re. Visual Studio: MSVC2019, 2017, 2015 and the upcoming 2021 version all are 32-bit only.

@mrjj
I haven't been using it long enough to comment on performance, other than that it hasn't crashed once today, which is already a win.
My hope would be that the frequent slowdowns during debugging are a thing of the past, but I have no reason to assume that switching to x64 will magically do anything for that. Sometimes it gets to the point where I´m forced to switch to MSVC2019 temporarily, for stepping through code, without proper Qt types support, just to be able to use it. I mean, both IDEs are using the same compiler & debugger, obviously, but the performance of the interface in Visual Studio has always been vastly superior to QtCreator in that respect. We'll see ...

@hskoglund
Interesting, and explained in this MS article. If it can handle large projects regardless, that's totally reasonable.

Interesting. In Windows 10 my qt creator consumes 300MB of ram. In Linux it consumes 1.2GB ram plus 3.5GB virt memory. Not sure how much virtual it consumes in Windows though. Didn't think it would be that high.
Edit: Windows 10 is 32 bit, Linux is 64 bit.
