this is the compiler error I get and this is main.cpp

include <fstream>

include <iostream>

include <filesystem>

include <chrono>

include <thread>

include <winrt/base.h>

include <winrt/windows.ui.viewmanagement.h>

int main (){
bool running = true;
winrt::Windows::UI::ViewManagement::UISettings Colsettings;
auto coloracc = Colsettings.GetColorValue(winrt::Windows::UI::ViewManagement::UIColorType::Accent);
std::cout << coloracc.B;
if (!std::filesystem::exists("color.inc")) {
running = false;
}
while (running)
{
std::this_thread::sleep_for(std::chrono::milliseconds(500));
std::cout << "aaaaaaaaaaa";
}
}

so yeah thanks for help I guess I can use any ide right

Answer 1

It can depend on the Windows SDK version

With 10.0.20348.0, I don't need any additional linked lib with WinRT
With older versions, I need to link with "WindowsApp.lib"
In some old threads, "OleAut32.lib" was needed too
