Question

我正在尝试按照此示例创建boost::lockfree::queue：http://www.boost.org/doc/libs/1_54_0/doc/html/lockfree/examples.html

我可以成功地为int（整数数据类型）创建它。但是我很难为Eigen :: MatrixXf创建一个队列。队列在SolveDGEM.h中声明。

boost::lockfree::queue<Eigen::MatrixXf> q_cam0;

我得到以下编译器错误，我无法理解

请参阅http://www.boost.org/doc/libs/1_59_0/doc/html/boost/lockfree/queue.html：

T必须有一个简单的析构函数

Eigen::MatrixXf不适用。

Eigen :: MatrixXf的boost :: lockfree队列
