用cuda 11.3编译pcl1.8的奇怪错误

Question

系统：cuda 11.3、gcc 7.5、boost 1.65.1、pcl 1.8.0

当我编译使用PCL库的代码时，它显示以下错误

/usr/include/pcl-1.8/pcl/io/file_io.h(264): error: namespace "boost" has no member "numeric_cast"

/usr/include/pcl-1.8/pcl/io/file_io.h(264): error: type name is not allowed

/usr/include/pcl-1.8/pcl/io/file_io.h(280): error: namespace "boost" has no member "numeric_cast"

/usr/include/pcl-1.8/pcl/io/file_io.h(280): error: type name is not allowed

/usr/include/pcl-1.8/pcl/io/file_io.h(346): error: namespace "boost" has no member "iequals"

/usr/include/pcl-1.8/pcl/io/file_io.h(372): error: namespace "boost" has no member "iequals"

/usr/include/pcl-1.8/pcl/io/pcd_io.h(485): error: name followed by "::" must be a class or namespace name

/usr/include/pcl-1.8/pcl/io/pcd_io.h(493): error: name followed by "::" must be a class or namespace name

我查看了

file_io.h

，发现相关代码是

<pcl/io/boost.h>

。在这个文件中，标头

<boost/numeric/conversion/cast.hpp>

包含numeria_cast函数，显然不包含这个标头。这个错误与宏

__CUDACC__

有关吗？我该如何解决这个问题？

/usr/include/pcl-1.8/pcl/io/boost.h

是：

#ifndef _PCL_IO_BOOST_H_
#define _PCL_IO_BOOST_H_

#if defined __GNUC__
#  pragma GCC system_header

是的，我用普通的 gcc 编译器解决了这个问题...不要使用 NVCC！
