使用 CMake 编译静态可执行文件

Compiling a static executable with CMake(使用 CMake 编译静态可执行文件)

本文介绍了使用 CMake 编译静态可执行文件的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

对于一个项目,我需要创建一个可执行文件,其中包含我使用的所有库(opencv、cgal),以便在没有这些库的计算机上执行它.目前,这是我的 CMakeLists.txt(我使用 linux).

for a project I need to create an executable that includes all the libraries that I used (opencv, cgal) in order to execute it on a computer that has not those libraries. Currently, this is my CMakeLists.txt (I use linux).

cmake_minimum_required(VERSION 2.8)
#set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -Wall")
set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -Wall -O2")
project( labeling )
set(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
add_library(OpenCV STATIC IMPORTED)
add_library(CGAL STATIC IMPORTED COMPONENTS Core)
add_library(GMP STATIC IMPORTED)
find_package(OpenCV REQUIRED)
find_package(CGAL QUIET COMPONENTS Core )
find_library(GMP_LIBRARY gmp /usr/lib)

include(src)
include( ${CGAL_USE_FILE} )
include( CGAL_CreateSingleSourceCGALProgram )


set(EXECUTABLE_OUTPUT_PATH ../bin)
set(CMAKE_EXE_LINKER_FLAGS "-static-libgcc -static-libstdc++")

include_directories( src )
include_directories( ${OpenCV_INCLUDE_DIRS} )

file(GLOB_RECURSE nei_SRC "src/*.cpp")
add_executable( nei_segmentation ${nei_SRC})
target_link_libraries( nei_segmentation ${OpenCV_LIBS} ${GMP_LIBRARY})

通过这种方式,我的可执行文件中只包含 GMP 和其他一些 C++ 库.我的问题是:如何创建一个 makefile 以便以静态方式自动包含所有库并仅创建一个包含所有库的大"可执行文件?你能帮我吗?

In such a way only GMP and some other c++ libraries are included in my executable. My question is: How can I create a makefile in order to automatically including all the libraries in a static manner and creating only a "big" executable that contains all the libraries? Can you help me?

推荐答案

作为全局 CMake 设置,在 add_executable 之前添加这些行,对 gcc/clang 有效:

As global CMake settings, add these lines before add_executable, valid for gcc/clang:

set(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
set(BUILD_SHARED_LIBS OFF)
set(CMAKE_EXE_LINKER_FLAGS "-static")

关于现代 CMake (3.x+ - target_link_libraries doc),您可以将标志应用于特定目标,方式如下:

On Modern CMake (3.x+ - target_link_libraries doc), you can apply the flag to specific targets, in this way:

target_link_libraries(your_target_name -static)

如果您使用 MSVC,则必须设置编译器和链接器标志:

If you're using MSVC, you have to set the compiler and linker flags:

set(CMAKE_FIND_LIBRARY_SUFFIXES ".lib")
target_compile_options(your_target_name [PUBLIC|PRIVATE] /MT)
target_link_options(your_target_name [PUBLIC|PRIVATE] /INCREMENTAL:NO /NODEFAULTLIB:MSVCRT)

如果您使用的是 MFC,则需要将标志指定为 1 见这里:

and if you are using MFC, you need to specify the flag to 1 see here:

 set(CMAKE_MFC_FLAG 1)
