Assimp Exporter 抛出分段错误

Question

我正在编写一个简单的程序，它应该使用 assimp 库导入一个步骤文件并将其转换为 collada 格式。

这是我的代码：

#include <assimp/Importer.hpp>
#include <assimp/scene.h>
#include <assimp/postprocess.h>
#include <assimp/Exporter.hpp>

#include <iostream>

int main()
{
    Assimp::Importer importer;
    const aiScene* scene = importer.ReadFile( "../cad/excavator.STEP", 
        aiProcess_CalcTangentSpace       | 
        aiProcess_Triangulate            |
        aiProcess_JoinIdenticalVertices  |
        aiProcess_SortByPType);

    if (!scene)
    {
        std::cout << "ERROR: model could not be loaded. \n";
        return 1;
    }

    // export the scene as a Collada file
    Assimp::Exporter exporter;
    exporter.Export(scene, "collada", "../solutions/newFile.dae");

    return 0;
}

这个脚本输出

Segmentation fault (core dumped)

CMake 输出警告，不知道有没有关系：

CMake Warning (dev) at /usr/lib/x86_64-linux-gnu/cmake/assimp-5.0/assimpTargets.cmake:54 (if):
  if given arguments:

    "ON"

  An argument named "ON" appears in a conditional statement.  Policy CMP0012
  is not set: if() recognizes numbers and boolean constants.  Run "cmake
  --help-policy CMP0012" for policy details.  Use the cmake_policy command to
  set the policy and suppress this warning.
Call Stack (most recent call first):

  CMakeLists.txt:5 (find_package)
This warning is for project developers.  Use -Wno-dev to suppress it.

使用以下 CMakeList.txt：

find_package(assimp REQUIRED)
add_executable(AssimpTest AssimpTest.cpp)
target_link_libraries(AssimpTest ${ASSIMP_LIBRARIES})

我在 Ubuntu 20.04.6 LTS 上，我正在使用 assimp 版本 5.0.1~ds0-1build1

非常感谢解决此问题的任何帮助。谢谢。
