c 11 – Clion&CMake.如何添加库(* .so)

概述我尝试在Clion IDE中编写代码(c / c).我需要在项目中添加一些共享库.在这一刻,我想只运行程序(只有主要功能),它将能够添加我的外部库libAPIenergy.so的任何功能.我从这个论坛尝试了一些解决方案,但任何人都没有帮助. 下面我将介绍给出最少错误的解决方案. 在主要功能我包括 #include "APIenergy.h" CMake文件 cmake_minimum_requir 我尝试在Clion IDE中编写代码(c / c).我需要在项目中添加一些共享库.在这一刻,我想只运行程序(只有主要功能),它将能够添加我的外部库libAPIenergy.so的任何功能.我从这个论坛尝试了一些解决方案,但任何人都没有帮助.

下面我将介绍给出最少错误的解决方案.

在主要功能我包括

#include "APIenergy.h"

CMake文件

cmake_minimum_required(VERSION 3.3)project(TestProject)add_library( libAPIenergy SHARED importED )link_directorIEs (/home/I/lib/linux/x86)set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -lAPIenergy ")set(SOURCE_fileS main.cpp APIenergy.h)add_executable(TestProject ${SOURCE_fileS})

和错误：

我还使用我的共享库添加到系统PATH LD_liBRARY_PATH direcytory

export LD_liBRARY_PATH=$HOME/lib/linux/x86

我的CMake在你的消化之后

cmake_minimum_required(VERSION 3.3)project(TestProject)add_library(libAPIenergy SHARED importED)SET_PROPERTY(TARGET libAPIenergy PROPERTY importED_LOCATION /home/I/x86/libAPIenergy.so)target_link_librarIEs(TestProject libAPIEnergy)set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")set(SOURCE_fileS main.cpp APIenergy.h)add_executable(TestProject ${SOURCE_fileS})

来自CMake的错误

Error:Cannot specify link librarIEs for target "TestProject" which is not built by this project.

还有一件重要的事情.我用项目将APIenergy.h文件部署到主目录.

.::编辑2 ::.

cmake_minimum_required(VERSION 3.3)project(TestProject)add_library(libAPIenergy SHARED importED)target_link_librarIEs(TestProject libAPIenergy)SET_PROPERTY(TARGET libAPIenergy PROPERTY importED_LOCATION /home/I/lib/x86/libAPIenergy.so)set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")set(SOURCE_fileS main.cpp APIenergy.h)add_executable(TestProject ${SOURCE_fileS})target_link_librarIEs(TestProject libAPIenergy)

错误

Error:Cannot specify link librarIEs for target "TestProject" which is not built by this project.

.::编辑3 ::.

现在CMake文件没有错误

cmake_minimum_required(VERSION 3.3)project(TestProject)add_library(libAPIenergy SHARED importED)SET_PROPERTY(TARGET libAPIenergy PROPERTY importED_LOCATION /home/I/lib/x86/libAPIenergy.so)set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")set(SOURCE_fileS main.cpp APIenergy.h)add_executable(TestProject ${SOURCE_fileS})target_link_librarIEs(TestProject libAPIenergy)

简单地说我尝试过午餐的代码

#include <iostream>#include "APIenergy.h" // include without error this mean without underlinedusing namespace std;int main() {    int ret = APIenergyInitialize(5); // IDE suggestions name function so is looks good    cout << "Hello,World!" << endl;    return 0;}

编译错误

/home/I/clion-1.2/bin/cmake/bin/cmake --build /home/I/.Clion12/system/cmake/generated/9faec492/9faec492/DeBUG0 --target TestProject -- -j 8[ 50%] linking CXX executable TestProject/home/I/lib/x86/libAPIenergy.so: error adding symbols: file in wrong formatcollect2: error: ld returned 1 exit statusCMakefiles/TestProject.dir/build.make:95: polecenia dla obIEktu 'TestProject' nIE powiodły sięmake[3]: *** [TestProject] Błąd 1CMakefiles/Makefile2:67: polecenia dla obIEktu 'CMakefiles/TestProject.dir/all' nIE powiodły sięmake[2]: *** [CMakefiles/TestProject.dir/all] Błąd 2CMakefiles/Makefile2:79: polecenia dla obIEktu 'CMakefiles/TestProject.dir/rule' nIE powiodły sięmake[1]: *** [CMakefiles/TestProject.dir/rule] Błąd 2Makefile:118: polecenia dla obIEktu 'TestProject' nIE powiodły sięmake: *** [TestProject] Błąd 2

解决方法 如果要从源文件创建自己的库,请使用add_library.

如果要指定目标需要链接到其他人的库,请使用target_link_librarIEs.
