【问题描述】：

我想使用WinRT (Windows 10) 构建一个现代 Windows 应用程序。我将Qt 5.13.1 UWP 套件用于Visual Studio 2017。构建项目时，显示很多编译错误：

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;

没有WinRT 代码它编译成功。任何想法如何使用Qt 配置WinRT？ Qt 需要哪些库才能运行 WinRT 代码？提前致谢。

【参考方案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，在旁边的下拉列表中选择“配置属性”->“C/C++”->“预处理器” “预处理器定义”选择“编辑”，删除行X64。我不知道这个定义是干什么用的，但它与 Windows.System.0.h 中的 ProcessorArchitecture::X64 枚举冲突。

PS。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。

【讨论】：

您好！我添加了#undef X64，现在它成功编译了。谢谢。

对了，我也是乌克兰德罗霍比奇市的:)
