在学习使用坐标变换监听tf2_ros::TransformListener时报错 创建监听对象 listener_ = std::make_shared<tf2_ros::TransformListener>(*buffer_,this); 按教程这里构造传入了两个参数,第二个是自身节点对象,可能导致了重复spin 解决方法:把this去了,只传入*buffer_一个参数...

1. 使用 std::make_shared 2. 直接使用 new 表达式 3. 从原始指针转换 4. 使用 std::shared_ptr 的别名构造 5. 从 std::unique_ptr 转换 std::shared_ptr 创建的几种常见方法,其中包括std::make_shared的使用,以及为何不直接使用new 1. 使用 std::make_shared std::make_shared 是创建 std::shared...

make_shared has to make an ifstream pointer, I tried it with a few other (of my own) classes and with these there is no issue. But maybe ifstream is not the only one that causes problems. When the make_shared line is changed to “shared_ptr<ifstream>{ new ifstream { “path...
