Try adding #define PCL_NO_PRECOMPILE at the top of your source code. The all-in-one installer contains template instantiations only for the most commonly used point types, but not for PointXYZINormal (see also here: https://pcl.readthedocs.io/projects/tutorials/en/master/adding_custom_ptype.html#how-to-add-a-new-pointt-type)

These errors come from the FLANN library, a dependency of PCL. The all-in-one installer includes the latest version of FLANN. Are you compiling your project as C++17 or C++20? random_shuffle was removed in C++17. PCL currently uses/is compiled as C++14, and I would recommend to use the same for your project.

Also, it might be better to use PCL_NO_PRECOMPILE only for those headers where you actually need it. So you could e.g. try

#define PCL_NO_PRECOMPILE
#include <pcl/features/normal_3d_omp.h>
#undef PCL_NO_PRECOMPILE

(same for other headers where you get link errors). Alternatively, make sure that PCL_NO_PRECOMPILE is not defined when including kdtree_flann.h (that's where the flann errors come from:

#undef PCL_NO_PRECOMPILE
#include <pcl/kdtree/kdtree_flann.h>
#define PCL_NO_PRECOMPILE

These settings have been generated in qt cmakelists.txt，set(CMAKE_CXX_STANDARD 17)，It should be based on the C++17 standard，But my problem still exists

cmake_minimum_required(VERSION 3.5)

project(zxtx_autocar VERSION 0.1 LANGUAGES CXX)

set(CMAKE_INCLUDE_CURRENT_DIR ON)

set(CMAKE_AUTOUIC ON) set(CMAKE_AUTOMOC ON) set(CMAKE_AUTORCC ON)

Okay, so would it be an option to change it to set(CMAKE_CXX_STANDARD 14)? If not, have you tried my suggestion with the more selective use of PCL_NO_PRECOMPILE?

There are no compilation errors, but there are cmake errors

[mvieth]

Have you tried setting VTK_DIR or VTK_ROOT to the correct directory?

[Haibara-z]

how did you solve this problem?
