Qt Snap7 Using Problem

[V0rtex]

@SGaist is there anyway communucate with Siemens Plc in qt library ?

If by network, then you have the Qt network classes but you will have to implement the protocol yourself.

I think that you should take the time to build Snap7 since it looks like it's already working as you need and maintained.

@SGaist i agree with you but i dont know how to do that.
i am not good when things get complicated :)

Hi
What about installing the visual studio compiler?
And please don't just install it all
as it eats many gigabytes. You only need the c++ role and SDK.
You have to download it from MS.

I tested with vs 2019 and it just build and ran

@mrjj i did it in visual studio It has S7.NET.
I wondered if it could be done with Qt.

@V0rtex
Hi
This is in Qt i mean.
You can install the visual studio compiler and a Qt that matches this compiler
and use that in Creator 100% like you do with MinGW.
Its just another qt install than the one for mingw.

@mrjj thank you it worked .
Happy new year.

@mrjj last question what is the different between mingw and msvc ?

[SGaist]

MSVC is from Microsoft (and closed source), MinGW is a port of gcc to Windows.

Hi
Qt wise. The Qt mingw packet comes with compiler and debugger.
The Qt Visual studio packet is only Qt and compiler and debugger must be downloaded from microsoft.

Visual studio is the standard on Windows, so often its 3rd party libraries come with project files / build instructions for visual studio
and more rarely directly support mingw tool chain.

That said, mingw is a fine compiler works super fine for most.

So what was the final solution@V0rtex
Is it just a compiler switch？
