c++ - Qt 与 WinRT C++ 构建问题

Question

我想使用 WinRT (Windows 10) 构建现代 Windows 应用程序。我为 Visual Studio 2017 使用 Qt 5.13.1 UWP 套件。构建项目时，显示大量编译错误:

代码:

testproject.pro

QT += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

CONFIG += c++17

# The following define makes your compiler emit warnings if you use
# any Qt feature that has been marked deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS

# You can also make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

SOURCES += \
    main.cpp \
    testproject.cpp

HEADERS += \
    testproject.h

FORMS += \
    testproject.ui

LIBS += -lwindowsapp

# Default rules for deployment.
#qnx: target.path = /tmp/$${TARGET}/bin
#else: unix:!android: target.path = /opt/$${TARGET}/bin
#!isEmpty(target.path): INSTALLS += target

testproject.h

#ifndef TESTPROJECT_H
#define TESTPROJECT_H

#include <QDialog>
#include <QDebug>
#include "winrt/Windows.System.Diagnostics.h"
using namespace winrt;
using namespace Windows::System::Diagnostics;

QT_BEGIN_NAMESPACE
namespace Ui { class TestProject; }
QT_END_NAMESPACE

class TestProject : public QDialog
{
    Q_OBJECT

public:
    TestProject(QWidget *parent = nullptr);
    ~TestProject();

private:
    Ui::TestProject *ui;
};
#endif // TESTPROJECT_H

testproject.cpp

#include "testproject.h"
#include "ui_testproject.h"

TestProject::TestProject(QWidget *parent)
    : QDialog(parent)
    , ui(new Ui::TestProject)
{
    ui->setupUi(this);
    init_apartment();

    auto info = SystemDiagnosticInfo::GetForCurrentSystem();
    auto memory = info.MemoryUsage().GetReport().TotalPhysicalSizeInBytes();
    qDebug() << memory;
}

TestProject::~TestProject()
{
    delete ui;
}

如果没有 WinRT 代码，它会成功编译。关于如何使用 Qt 配置 WinRT 有什么想法吗？ Qt 运行WinRT 代码需要哪些库？提前致谢。

Answer 1

尝试在 #include "winrt/Windows.System.Diagnostics.h" 之前添加 #undef X64 或转到您的项目设置，选择 “Configuration” Properties” -> “C/C++” -> “Preprocessor”，在 “Preprocessor Definitions” 旁边的下拉列表中选择 “Edit”，删除行X64。我不知道这个定义是做什么用的，但它与 Windows.System.0.h 中的 ProcessorArchitecture::X64 枚举冲突。

附言。这个答案只是一个复制的猜测，因为我无法理解屏幕截图上的错误。通常从输出面板复制粘贴文本比错误列表提供更多信息。
