c++ - boost::Eigen::MatrixXf 的无锁队列

Question

我正在尝试创建一个 boost::lockfree::queue 下面的例子:http://www.boost.org/doc/libs/1_54_0/doc/html/lockfree/examples.html

我可以为 int(整数数据类型)成功创建它。但是我很难为 Eigen::MatrixXf 创建队列。该队列在 SolveDGEM.h 中声明。

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

我收到以下我无法理解的编译器错误

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

T must have a trivial destructor

这对于 Eigen::MatrixXf 是不正确的。
