使用boost::mpl模块实现vector_c相关的测试程序

在C++编程中,Boost库是一个广泛使用的工具库,其中的mpl(元编程库)模块提供了一种元编程的方式来进行编译期计算。在mpl模块中,vector_c是一个常用的数据结构,它可以用于在编译期创建和操作整数序列。本文将介绍如何使用boost::mpl模块实现vector_c相关的测试程序。

首先,我们需要在项目中包含Boost库的头文件。在使用mpl模块时,我们需要包含<boost/mpl/vector_c.hpp>头文件。接下来,我们可以使用boost::mpl::vector_c类来定义一个整数序列。

下面是一个使用boost::mpl::vector_c定义整数序列的示例代码:

#include <iostream>
#include <boost/mpl/vector_c.hpp>

一直出现这种报错是为什么/usr/include/boost/mpl/aux_/preprocessed/gcc/plus.hpp:68:8: note:boost::mpl::plus’ 68 | struct plus | ^~~~ In file included from /usr/include/pcl-1.10/pcl/point_types.h:44, from /usr/include/pcl-1.10/pcl/common/impl/copy_point.hpp:41, from /usr/include/pcl-1.10/pcl/common/copy_point.h:58, from /usr/include/pcl-1.10/pcl/common/impl/io.hpp:45, from /usr/include/pcl-1.10/pcl/common/io.h:586, from /usr/include/pcl-1.10/pcl/io/file_io.h:41, from /usr/include/pcl-1.10/pcl/io/pcd_io.h:44, from /opt/ros/noetic/include/pcl_conversions/pcl_conversions.h:70, from /home/nonobody/catkin_ws/src/grid_path_searcher/src/demo_node.cpp:4: /usr/include/pcl-1.10/pcl/point_types.h:535:1: error: ‘plus’ is not a member of ‘pcl::traits’ 535 | POINT_CLOUD_REGISTER_POINT_STRUCT (pcl::MomentInvariants, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /usr/include/pcl-1.10/pcl/point_types.h:535:1: note: suggested alternatives: In file included from /usr/include/c++/9/string:48, from /usr/include/c++/9/bits/locale_classes.h:40, from /usr/include/c++/9/bits/ios_base.h:41, from /usr/include/c++/9/ios:42, from /usr/include/c++/9/ostream:38, from /usr/include/c++/9/iostream:39, from /home/nonobody/catkin_ws/src/grid_path_searcher/src/demo_node.cpp:1: /usr/include/c++/9/bits/stl_function.h:167:12: note: ‘std::plus’ 167 | struct plus : public binary_function<_Tp, _Tp, _Tp> | ^~~~ In file included from /usr/include/boost/mpl/aux_/include_preprocessed.hpp:37, from /usr/include/boost/mpl/aux_/arithmetic_op.hpp:34, from /usr/include/boost/mpl/plus.hpp:19, from /usr/include/boost/mpl/vector/aux_/iterator.hpp:19, from /usr/include/boost/mpl/vector/aux_/vector0.hpp:22, from /usr/include/boost/mpl/vector/aux_/clear.hpp:18, from /usr/include/boost/mpl/vector/vector0.hpp:24, from /usr/include/boost/mpl/vector/vector10.hpp:18, from /usr/include/boost/mpl/vector/vector20.hpp:18, from /usr/include/boost/mpl/vector.hpp:36, from /usr/include/boost/math/policies/policy.hpp:14, from /usr/include/boost/math/policies/error_handling.hpp:21, from /usr/include/boost/math/special_functions/round.hpp:14, from /opt/ros/noetic/include/ros/time.h:58, from /opt/ros/noetic/include/ros/ros.h:38, from /opt/ros/noetic/include/pcl_conversions/pcl_conversions.h:42, from /home/nonobody/catkin_ws/src/grid_path_searcher/src/demo_node.cpp:4:
