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)
