cmake下使用boost,以shared_ptr和make_shared举例Cmake文件配置boost shared_ptr和make_shared举例

Cmake文件配置

首先需要在CmakeLists.txt文件中加入下面这段

记得“

YourExeName

YourSourceCodeName

”这两个部分需要替换成自己的源文件名字和自己想生成的目标文件名字

find_package(Boost)
if(Boost_FOUND)
    include_directories(${Boost_INCLUDE_DIRS})
    add_executable(YourExeName YourSourceCodeName.cpp)
    target_link_libraries(main ${Boost_LIBRARIES})
endif()
           

boost shared_ptr和make_shared举例

#include <iostream>
#include <boost/shared_ptr.hpp>
#include <boost/make_shared.hpp>
int main() {
    boost::shared_ptr<int> ptr = boost::make_shared<int>(1);
    std::cout << *ptr << std::endl;
    return 0;
}
