使用CMake在Qt应用程序中静态链接库

Question

使用CMake在Qt应用程序中静态链接库

5

我将为您翻译如下内容：

我正在尝试使用CMake构建一个使用静态库的Qt5应用程序，但是我无法弄清楚如何静态链接文件。我已经卡在这个问题上几个小时，并尝试在Google上找到任何线索，但没有好运。

CMakeLists.txt：

cmake_minimum_required(VERSION 3.9 FATAL_ERROR)   

project (myDemo VERSION 0.1 LANGUAGES CXX)

### Didn't make any difference:
###set(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
   
set (myDemo_VERSION_MAJOR 1)    
set (myDemo_VERSION_MINOR 0)

set(CMAKE_BINARY_DIR ${CMAKE_SOURCE_DIR}/bin)    
set(EXECUTABLE_OUTPUT_PATH ${CMAKE_BINARY_DIR})    
set(LIBRARY_OUTPUT_PATH ${CMAKE_BINARY_DIR})
set(CMAKE_INSTALL_PREFIX ${PROJECT_BINARY_DIR}/installation)

set(CMAKE_AUTOMOC ON)

set(SOURCES ${PROJECT_SOURCE_DIR}/src)

#### This made the build process reach 100%, but still exiting with the same error message
###set(Qt5_USE_STATIC_LIBS ON)    
###set(Qt5_USE_STATIC_RUNTIME ON)

# Find the necessary qt libraries    
find_package(Qt5 COMPONENTS Gui Quick Qml Multimedia)

if ( NOT Qt5_FOUND )    
 message(FATAL_ERROR "Package QT not found!")    
endif( )

# add the executable    
add_executable(myDemo src/main.cpp     
    src/somefile.cpp     
    src/somefile.h )

target_include_directories(myDemo PRIVATE Qt5_DIR)    
target_compile_features(myDemo PUBLIC cxx_std_17)     

target_link_libraries (myDemo Qt5::Gui Qt5::Qml Qt5::Quick Qt5::Multimedia ${ADDITIONAL_LIBRARIES} -static)      

install (TARGETS myDemo DESTINATION bin)

cmake 命令没有错误退出，但是 make 命令执行时出现以下错误信息：

/usr/bin/ld: attempted static link of dynamic object `/opt/qt5/lib/libQt5Quick.so.5.9.1'

collect2: error: ld returned 1 exit status

CMakeFiles/myDemo.dir/build.make:204: recipe for target '../bin/myDemo' failed

make[2]: *** [../bin/myDemo] Error 1

CMakeFiles/Makefile2:67: recipe for target 'CMakeFiles/myDemo.dir/all' failed

make[1]: *** [CMakeFiles/myDemo.dir/all] Error 2

Makefile:129: recipe for target 'all' failed

make: *** [all] Error 2

我在虚拟机上运行 Ubuntu 操作系统，应用程序使用 QML/Qt (5.9) 实现，使用的是 Visual Studio Code 而不是 Qt Creator。我之前没有使用过 CMake。

有人知道如何链接静态 Qt 库吗？编辑问题可能是我使用的是开源版的 Qt，难道这意味着开源版不支持静态构建吗？

首先，您应该对Qt进行静态构建。 - Dmitry Sazonov

Qt的开源版本是否支持静态构建？ - KMK

当然可以，但您需要为您的软件使用GPL许可证。 - Dmitry Sazonov

你需要从源代码构建自己的静态版本Qt。然而，之后你可能会遇到这个bug，它使得使用静态Qt + cmake变得非常困难。 - Stefan Pfeifer

首先，注意这个项目https://github.com/siavashk/qt5-static-hello-world，但感觉它只在MacOS上可能成功过。在DoQtMess.cmake中注释掉set(QT_EXTRA_LIBS ...行和main.cpp中的Q_IMPORT_PLUGIN(QCocoaIntegrationPlugin)行后，在没有任何静态特定参数的情况下运行cmake，现在我可以在Linux上构建并运行它。然而，我可以看到（使用ldd）它是动态链接到我的系统Qt安装的。

我可以通过调用以下方式的cmake来使用不同的Qt安装：

$ export CMAKE_PREFIX_PATH="/path/to/other/qt/lib/cmake/Qt5"

ldd 的输出确认它将链接到那些 .so。

使用相同的过程，但将 CMAKE_PREFIX_PATH 指向静态编译的安装树，编译的文件肯定更多：

这是一个重要的结论：在Qt-cmake集成/构建支持工作中，我认为现在比以前要容易得多。也就是说，当我尝试使用Qt 5.12进行此操作时，我不得不插入许多Q_IMPORT_PLUGIN行，并且需要通过试错来确定哪个是必需的。因此，我要提出第一步静态链接Qt的方法是使用版本5.15。

最重要的是，它实际上按照预期运行！

如果您使用的是Windows，我建议使用MSYS2，然后使用pacman静态安装Qt并安装CMake和GCC（如果要使用pro文件），这将减轻以后的工作负载。然后在Qt Creator中调整套件编译器，使用刚刚安装的msys2的静态编译器，因为应用程序和库使用的编译器必须相同。这些命令是针对编译器的，我不记得安装qt的命令了。

 pacman -S mingw-w64-x86_64-gcc

 gcc -v #to make sure gcc is installed

 g++ -v # check g++ compiler

 pacman -S make

 pacman --needed -S mingw-w64-x86_64-toolchain

如果您使用Mac电脑，过程将是相同的，但使用brew，您的cmake文件中将有一个异常，请添加以下内容

set(CMAKE_EXE_LINKER_FLAGS "-lobjc -framework IOKit -framework CoreFoundation")
