Installation QT and OpenCV interfaces

[Stevendragoes]

Hi All,

I want to make a 32 bit QT Application on my Windows 10.
I also want the QT application to integrate OpenCV.
I have Microsoft Visual Studio 2019 with version 16.3.7

I have the following Options on my QT installer
QT 5.12.6,QT 5.12.5, QT 5.12.4,QT 5.12.3, QT 5.12.2, QT 5.9.9

I need guidance on what versions of OpenCV and QT to install on my computer based on my application requirements of 32 bit.

Any Help is appreciated. Thanks in advance

In addition,what configuration Should I use to compile them? There are 2 ways stated in the tutorials that I can use MinGW or MSVC2017. What are the differences? Would any compilation suffice for the above requirements?

Hi,

The recommendation is to use the latest LTS.

As for the compiler, since you are dealing with C++ libraries, you have to ensure that all your librairies are compiled with the same compiler.

As for MSVC vs MinGW, you have to install Visual Studio yourself (Microsoft Rule). MinGW can be installed through the online installer.

Hello @SGaist thank you for the response. Could. You enlighten me on what is the latest LTS? Maybe a link to tell me how to check for the latest LTS

C++ libraries I use the g++ and cmake to compile them. Am I doing the right thing?

I already have the visual studio stated above. Will that do?

LTS = Long Term Support

Do you mean you are using MinGW ?

[Stevendragoes]

@SGaist I have tutorials on Using MinGW or Visual Studios to link the libraries of OpenCV to QT. That's what I meant.

@Mucip thanks for the YouTube video. As I am overseas I'll look at it when I'm back at work

Hello @SGaist and all who are reading this

I have installed the following Items from QT OpenSource Version
Under Developer and Design Tools,

and ''CMake 3.16.0 32-bit''

Under QT, I have installed the following

Are those Enough for me to incorporate OpenCV and QT?

Hello again,
I have also downloaded MSVC 2017 to be compliant with the QT 5.12.6

Yes, if 32bit apps are OK for you.
