Question

我是C编程的新手，想要使用igraph库。

我是通过自制软件安装的。

brew install igraph

之后我从main.cpp中的igraph c教程复制第一个例子，并将include igraph更改为

#include "igraph/igraph.h"

Clion提出了igraph函数和类型。

尝试构建此错误消息：

/Applications/CLion.app/Contents/bin/cmake/bin/cmake --build 
/Users/username/development/graph_clustring/cmake-build-debug --target 
graph_clustring -- -j 4

我认为我应该修复我的CMake文件，并帮助CMake通过自制软件找到lib isntal。

CMake文件：

cmake_minimum_required(VERSION 3.8)
project(graph_clustring)

set(CMAKE_CXX_STANDARD 11)

set(SOURCE_FILES main.cpp)

add_executable(graph_clustring ${SOURCE_FILES})

Answer 1

我能够通过向CMake添加target_link_libraries命令来解决该问题。看起来应该像这样

make_minimum_required(VERSION 3.8) 
enter code here

project(graph_clustring)

set(CMAKE_CXX_STANDARD 11)

set(SOURCE_FILES main.cpp)

add_executable(graph_clustring ${SOURCE_FILES})
target_link_libraries(graph_clustring, igraph.a)

在通过自制软件安装的OSX上使用igraph
