cmake-创建一个静态库

CMake - Creating a static library

本文关键字：一个 静态 创建 cmake-      更新时间：2023-10-16

我在项目中有两个文件，称为 Test4：

Structure.h Structure.c

我想创建一个静态库，该库可以由想要使用这些文件的其他项目加载。这是我目前的CMAKE文件：

cmake_minimum_required(VERSION 3.6)
project(Test4)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES Structure.c Structure.h)
add_library(Test4 STATIC ${SOURCE_FILES})

当我使用该cmake文件构建时，不会生成静态库。什么都没发生。我做错了吗？

我正在使用Clion IDE。

add_library Line应该是您所需要的。请参阅此示例代码我刚刚写的是为了测试创建一个，然后使用它(在Ubuntu 16.04上(：

structure.h：

int sum( int a, int b );

structure.c：

int sum( int a, int b ) { 
    return a + b;
}

main.c：

#include <stdio.h>
#include "Structure.h"
int main() {
    int a = 5;
    int b = 8;
    int c = sum( a, b );
    printf( "sum of %d and %d is %dn", a, b, c );
    return 0;
}

cmakelists.txt：

# CMake instructions to make the static lib
ADD_LIBRARY( MyStaticLib STATIC
             Structure.c )

# CMake instructions to test using the static lib
SET( APP_EXE StaticTest )
ADD_EXECUTABLE( ${APP_EXE}
                Main.c ) 
TARGET_LINK_LIBRARIES( ${APP_EXE}
                       MyStaticLib )

，然后是运行它的输出：

我也有同样的问题。我错过的是创建构建文件的位置。

Clion在cmake-build-*目录下制作库或Excectrables。如果Build, Execution, Deployment > CMake > Configuration是Debug，则在cmake-build-debug中创建LIB文件(.a(。

在使用命令 cmake。之后> ，撤销它，然后在r目录中获得.a文件。访问https://cmake.org/cmake/help/v3.0/command/add_library.html将为您提供帮助！
