c++ - Qt与WinRT C++构建问题

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

 

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

测试项目

#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

测试项目

#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，它将成功编译。有什么想法如何使用WinRT配置Qt吗？ Qt运行WinRT代码需要哪些库？提前致谢。

最佳答案

尝试在#undef X64之前添加#include "winrt/Windows.System.Diagnostics.h"或转到项目设置，选择“配置属性”->“ C / C ++”->“预处理器”，在“预处理器定义”旁边的下拉列表中选择“编辑”，然后删除X64行。我不知道此定义的用途，但它与Windows.System.0.h中的ProcessorArchitecture::X64枚举冲突。

PS。这个答案只是复制的猜测，因为我对屏幕截图上的错误不太了解。通常，从“输出”面板复制粘贴文本比“错误列表”提供更多信息。
