描述

Your Environment

Operating System and version: Win10
Compiler:
PCL Version: 1.9.1

Context

In general, we can find PCL .hpp are included at end of header file

#ifdef PCL_NO_PRECOMPILE
#include <pcl/....hpp>
#endif

But why some .hpp are not. For example: pcl/surface/impl/grid_projection.hpp: it is included in .cpp pcl/outofcore/impl/octree_base.hpp: it need to be included by user self

貢獻者指南

研究方向: 識別 PCL 原始碼中所有未在相應 .h 檔案中透過 #ifdef PCL NO PRECOMPILE 巨集包含的 .hpp 檔案，並新增 include 行。例如，pcl/surface/impl/grid projection.hpp 僅在 .cpp 中包含，pcl/outofcore/impl/octree base.hpp 需要使用者手動包含。確保這些檔案在對應的 .h 檔案中被包含。
