c – /boost/lockfree/queue.hpp：错误：静态断言失败：(boost :

我添加了#include< boost / lockfree / queue.hpp&gt ;;更改了第130行,std :: queue< action> m_actions;,来自boost :: lockfree :: queue< action> m_actions ;;删除所有与锁定有关的行;并将第103行,m_actions.pop();更改为m_actions.pop(a);.

在将broadcast_server_lockfree = SConscript(‘#/ broadcast_server_lockfree / SConscript’,variant_dir = builddir’casting_server_lockfree’,duplicate = 0)添加到项目根目录的SConstruct并在broadcast_server_lockfree目录中使用broadcast_server的SConstruct后,我在项目根目录中scons broadcast_server_lockfree时出现这些错误：

我对c几乎一无所知,对错误的搜索没有产生任何结果(因为我不知道我在读什么).

这是boost :: lockfree :: queue示例,如果有帮助的话. http://boost-sandbox.sourceforge.net/doc/html/lockfree/examples.html

请告诉我如何纠正这个问题.

行动

struct action {
    action(action_type t,connection_hdl h) : type(t),hdl(h) {}
    action(action_type t,server::message_ptr m) : type(t),msg(m) {}

    action_type type;
    websocketpp::connection_hdl hdl;
    server::message_ptr msg;
};
