Eigen::MatrixXf 的 boost::lockfree 队列

Question

我正在尝试创建boost::lockfree::queue以下示例： http://www.boost.org/doc/libs/1_54_0/doc/html/lockfree/examples.html

\n\n

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 创建队列。队列声明于SolveDGEM.h。

\n\n

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

\n\n

我收到以下我无法理解的编译器错误

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

这对于 来说是不正确的Eigen::MatrixXf。
