如何在 Qt 项目中引用第 3 方 dll/库
我已经尝试解决这个问题一个小时了。我拥有的是一个在 Qt Creator 中打开的简单 Qt 项目。我想做的是将 SDL 库 (dll) 与我的 Qt 项目一起使用。
在 Visual Studio 中，我通常会使用提供此功能的 VS 工具添加对此 dll 的引用。在 Qt Creator 中，我打开了项目的 .pro 文件，并为 STD dll 添加了一个 LIB 条目
# Add more folders to ship with the application, here
folder_01.source = qml/BoxGame
folder_01.target = qml
DEPLOYMENTFOLDERS = folder_01
# Additional import path used to resolve QML modules in Creator's code model
QML_IMPORT_PATH =
symbian:TARGET.UID3 = 0xEED812B5
# Smart Installer package's UID
# This UID is from the protected range and therefore the package will
# fail to install if self-signed. By default qmake uses the unprotected
# range value if unprotected UID is defined for the application and
# 0x2002CCCF value if protected UID is given to the application
#symbian:DEPLOYMENT.installer_header = 0x2002CCCF
# Allow network access on Symbian
symbian:TARGET.CAPABILITY += NetworkServices
# If your application uses the Qt Mobility libraries, uncomment the following
# lines and add the respective components to the MOBILITY variable.
# CONFIG += mobility
# MOBILITY +=
LIBS += C:\Users\vata\Desktop\DskProj\Dsk-build-desktop\debug\SDL.dll
# The .cpp file which was generated for your project. Feel free to hack it.
SOURCES += main.cpp \
blockboxes.cpp \
block.cpp \
boxengine.cpp \
boxgame.cpp \
point.cpp \
gamecontroller.cpp \
gamecontrollermod.cpp
# Please do not modify the following two lines. Required for deployment.
include(qmlapplicationviewer/qmlapplicationviewer.pri)
qtcAddDeployment()
HEADERS += \
blockboxes.h \
block.h \
boxengine.h \
boxgame.h \
Globals.h \
point.h \
gamecontroller.h \
gamecontrollermod.h \
controller.h
，但是，这似乎不包括 Qt 中供我使用的库。编译时，我仍然收到 SDL.h: No such file or directory 错误消息。我将不胜感激任何帮助解决这个问题并可能为未来学习的帮助，因为我打算在我的开发工作中更频繁地使用 Qt。

Been trying to figure this out for an hour now. What I have is a simple Qt Project open in Qt Creator. What I would like to do is use the SDL library (dll) with my Qt project.
In visual Studio, what I would normall do is add a reference to this dll using VS tool that provides for that. In Qt creator, I opened the .pro file for my project, and added a LIB entry for the STD dll
# Add more folders to ship with the application, here
folder_01.source = qml/BoxGame
folder_01.target = qml
DEPLOYMENTFOLDERS = folder_01
# Additional import path used to resolve QML modules in Creator's code model
QML_IMPORT_PATH =
symbian:TARGET.UID3 = 0xEED812B5
# Smart Installer package's UID
# This UID is from the protected range and therefore the package will
# fail to install if self-signed. By default qmake uses the unprotected
# range value if unprotected UID is defined for the application and
# 0x2002CCCF value if protected UID is given to the application
#symbian:DEPLOYMENT.installer_header = 0x2002CCCF
# Allow network access on Symbian
symbian:TARGET.CAPABILITY += NetworkServices
# If your application uses the Qt Mobility libraries, uncomment the following
# lines and add the respective components to the MOBILITY variable.
# CONFIG += mobility
# MOBILITY +=
LIBS += C:\Users\vata\Desktop\DskProj\Dsk-build-desktop\debug\SDL.dll
# The .cpp file which was generated for your project. Feel free to hack it.
SOURCES += main.cpp \
blockboxes.cpp \
block.cpp \
boxengine.cpp \
boxgame.cpp \
point.cpp \
gamecontroller.cpp \
gamecontrollermod.cpp
# Please do not modify the following two lines. Required for deployment.
include(qmlapplicationviewer/qmlapplicationviewer.pri)
qtcAddDeployment()
HEADERS += \
blockboxes.h \
block.h \
boxengine.h \
boxgame.h \
Globals.h \
point.h \
gamecontroller.h \
gamecontrollermod.h \
controller.h
However, that does not seem to include the Library in Qt for my use. When I compile, I still get an SDL.h: No such file or directory error message. Would appreciate any help in figuring this out and probably learning for the future as I intend to use Qt more often than not for my development work.

SDL.h 是 C 头文件，而不是库。为了让编译器找到它，您需要将其目录添加到 qmake 的 INCLUDEPATH 中。例如：（
提示：您可以使用
/而不是\，以避免将\解释为转义字符。）SDL.h is a C header file, not a library. For the compiler to find it, you need to add its directory to qmake's INCLUDEPATH. For example:
(Tip: you can use
/instead of\to stay clear of possible interpretations of\as an escape character.)尝试类似：
LIBS += -LC:\\Users\\vata\\Desktop\\DskProj\\Dsk-build-desktop\\debug -lsdlTry something like:
LIBS += -LC:\\Users\\vata\\Desktop\\DskProj\\Dsk-build-desktop\\debug -lsdl
