Error in toolchain.prf when building new project

[glarson]

I'm a new user, trying to build a new, empty project.
Using Qt Creator 4.6.0.
The project is a Qt Widgets Application for desktop.
Here's an image of the kit I'm using for the build:

I'm getting an error when building it, and here's an image of the error:

If I use MinGW 32bit kit, it seems to work. But with MSVC2017 64bit, I'm getting the error. I have no idea what it is doing at the point of error, as I am completely new to using Qt. Any ideas on how I can get it to build without error?

@glarson Can you go to "Compile Output" (tab 5 at the bottom) and copy paste the whole build log here?

Thanks, here is my Compile Output:

Hi and welcome to devnet,

Can you show the content of toolchain.prf:208 ?

[glarson]

@SGaist It won't let me upload a whole file yet, but if you look at my 2nd image above, it shows precisely where the error occurred. That is in toolchain.prf. It is calling eval($$v).

[SGaist]

Sorry, I didn't had the image when I answered.

Looks pretty strange. Do you have Visual Studio installed in the standard location ?

Can you modify toolchain.prf and add message("Test: $$v) before line 208 too see what might be giving that error ?

[glarson]

@SGaist I did as you said, and the message it printed was "Active code page: 65001".

Very strange - then I recalled that some time ago I added something to my registry to set the code page of my command prompt windows to 65001:

I had followed the instructions in this YouTube video, which had me put an autorun instruction into my registry:

So I have just removed that item from the registry, and now the project builds and runs!

So thank you and jsulm for your help on this. Cheers! ☕
It was such an obscure thing.

Glad you found out and thanks for sharing !

Happy coding :)
