Question

我已经使用Qt VS Tools为Visual Studio 2019创建了Qt类库。我将此库也包含在我也使用Qt VS工具制作的Qt项目中，但现在我的项目无法建立。

那是我项目的.pro文件：

# ----------------------------------------------------
# This file is generated by the Qt Visual Studio Tools.
# ------------------------------------------------------

TEMPLATE = app
TARGET = JanturiolGameServer
DESTDIR = ./Win32/Debug
QT += core network gui widgets networkauth
CONFIG += debug
DEFINES += _UNICODE _ENABLE_EXTENDED_ALIGNED_STORAGE WIN64 QT_DLL QT_NETWORK_LIB QT_NETWORKAUTH_LIB QT_WIDGETS_LIB
INCLUDEPATH += ../../JanturiolLib \
    ./GeneratedFiles \
    . \
    ./GeneratedFiles/$(ConfigurationName)
LIBS += -L"../../JanturiolLib"
DEPENDPATH += .
MOC_DIR += ./GeneratedFiles/$(ConfigurationName)
OBJECTS_DIR += debug
UI_DIR += ./GeneratedFiles
RCC_DIR += ./GeneratedFiles
include(JanturiolGameServer.pri)

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/../JanturiolLib/Win32/release/ -lJanturiolLib
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/../JanturiolLib/Win32/debug/ -lJanturiolLib
else:unix: LIBS += -L$$PWD/../JanturiolLib/Win32/ -lJanturiolLib

INCLUDEPATH += $$PWD/../JanturiolLib
DEPENDPATH += $$PWD/../JanturiolLib

那是我图书馆的.pro文件：

# ----------------------------------------------------
# This file is generated by the Qt Visual Studio Tools.
# ------------------------------------------------------

TEMPLATE = lib
TARGET = JanturiolLib
DESTDIR = ./Win32/Release
QT += core xml network gui uitools widgets networkauth
CONFIG += release
DEFINES += _UNICODE _ENABLE_EXTENDED_ALIGNED_STORAGE WIN64 QT_DLL QT_NETWORK_LIB QT_NETWORKAUTH_LIB QT_UITOOLS_LIB QT_WIDGETS_LIB QT_XML_LIB JANTURIOLLIB_LIB
INCLUDEPATH += ./GeneratedFiles \
    . \
    ./GeneratedFiles/$(ConfigurationName)
DEPENDPATH += .
MOC_DIR += ./GeneratedFiles/$(ConfigurationName)
OBJECTS_DIR += release
UI_DIR += ./GeneratedFiles
RCC_DIR += ./GeneratedFiles
include(JanturiolLib.pri)

那是PlayerChracter.h：

#pragma once
#include "BaseCharacter.h"
#include <string>

enum CharacterClass{warrior, mage, ranger};

//position
struct Pos
{
    int xPos;
    int yPos;
};

class PlayerCharacter : public BaseCharacter
{
public:
    PlayerCharacter(std::string charName);
    virtual ~PlayerCharacter();

protected:
    std::string name;
    Pos position;
};

那是PlayerChracter.cpp：

    #include "PlayerCharacter.h"

   PlayerCharacter::PlayerCharacter(std::string charName)
    {
        name = charName;
        position.xPos = 0;
        position.yPos = 0;
    }


    PlayerCharacter::~PlayerCharacter()
    {
    }

如果我尝试通过Visual Studio构建项目，则会收到此错误：

如果我尝试通过Qt创建者4. 9. 0构建项目，则会收到此错误：

这是.lib文件的路径：

Answer 1

在项目文件中，您已经设置了WIN64，但是编译器的输出状态为Debug Win32。

可能的原因，请参见“ https://docs.microsoft.com/en-us/cpp/error-messages/tool-errors/linker-tools-error-lnk2019?view=vs-2019”中的“尝试将64位库链接到32位代码或将32位库链接到64位代码”

尝试使用包含的Qt类库库构建项目时发生错误
