QtFuture not found

[noone]

according to docs, I only need to add following in my cmake file:-

find_package(Qt6 COMPONENTS Core REQUIRED)
target_link_libraries(mytarget PRIVATE Qt6::Core)

to include QtFuture. But i'm getting compiltation error

/home/fire/untitled1/main.cpp:3: error: QtFuture: No such file or directory
/home/fire/untitled1/main.cpp:3:10: fatal error: QtFuture: No such file or directory
    3 | #include <QtFuture>
      |          ^~~~~~~~~~

here is my complete cmake file:-

cmake_minimum_required(VERSION 3.15)

project(untitled1 LANGUAGES CXX)

set(CMAKE_INCLUDE_CURRENT_DIR ON)

set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)

set(CMAKE_CXX_STANDARD 20)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

find_package(Qt6 COMPONENTS Core Quick REQUIRED)

set(PROJECT_SOURCES
        main.cpp
        qml.qrc
)

qt_add_executable(untitled1 ${PROJECT_SOURCES})
target_link_libraries(untitled1 PRIVATE Qt6::Core Qt6::Quick)

I have installed qt6 from pacman from manjaro repositories

QtFuture

There is and was no such include in Qt. You most likley want to include QFuture

I thought that too. But the OP gave this link: https://doc-snapshots.qt.io/qt6-dev/qtfuture.html#connect

And at the top of that page it has:

QtFuture Namespace

Header: #include <QtFuture>

Contains miscellaneous identifiers used by the QFuture class

And a lot of the methods there say

This function was introduced in Qt 6.1.

so I think it's from the future ;-)

So what's that about? :)

When the OP is using qt6.dev then all is fine, yes

https://doc.qt.io/qt-6/qfuture.html

Ok, the link is also valid for Qt6. Looks like a doc error.

Thanks. I have no idea whether he is or isn't, I just looked at the link, I don't know where he got it from :)
