@Toruha Please post text as text, not screen shots.
Why do you add the headers from that library directly? It is enough to set INCLUDEPATH as ayou're already doing.
Did you build the library already? -
@jsulm I built the library via Cmake and compiled it in Visual Studio 2019. Then I added the library as "External library" referring to https://doc.qt.io/qtcreator/creator-project-qmake-libraries.html.

I'm trying to add a library to a project. https://github.com/AlexanderVatov/DuckX. Using qmake.
I encountered the following errors when executing the test code proposed by the author of the library:
.pro file looks like this:
To solve the problem, I tried to rebuild the project.

c++11 console
This doesn't tell me much, really!
Did you use the Microsoft compiler (same as in Visual Studio)? Or did you use MinGW? -

@Toruha You can't mix different compilers like in this case Microsoft compiler and MinGW. You have to build both, the library and your app, with same compiler.
But from your screen-shot above it rather looks like you're using Microsoft compiler...
-
Right, the _ITERATOR_DEBUG_LEVEL, RuntimeLibrary issues above rather show that you've done a Release build of duckx, but want to use it in a debug build of your app. This won't work; you need to compile both in the same configuration.
