CGAL：对 _createImage 的未定义引用

Posted 2023-02-22

【中文标题】CGAL：对 _createImage 的未定义引用

【英文标题】：CGAL: undefined reference to _createImage

【发布时间】：2018-01-14 12:21:46

【问题描述】：

我得到了对 `_createImage(int, int, int, int, float，float，float，int，WORD_KIND，SIGN)'，当我尝试参与 代码来自： https://doc.cgal.org/latest/Mesh_3/Mesh_3_2random_labeled_image_8h-example.html

基本上我要做的是将 ITK 图像转换为 CGAL image_3，为此我需要用我自己的数据初始化 image_3，但它给了我对 _create_image 的未定义引用。我添加了 ImageIO 和 Image_3 的标头

const int dim = 400;
 _image* image = _createImage(dim, dim, dim, 1,
                              1.f, 1.f, 1.f, 1,
                              WK_FIXED, SGN_UNSIGNED);

Cmakelist.txt

find_package(CGAL QUIET)
if( CGAL_FOUND)
include_directories("/usr/local/include")
message(STATUS "CGAL status:")
message(STATUS "    libraries: $CGAL_LIB")
message(STATUS "    include path: $CGAL_INCLUDE_DIRS")
endif(CGAL_FOUND)
target_link_libraries(main  meshlib iolib $ITK_LIBRARIES $CGAL_LIB )

标志

方法

void VolumetricImage::ItkImageToCgalImage(itk::Image<char, 3>::Pointer &in_volumetric_image, CGAL::Image_3 &out_image) 
  typedef itk::Image< char, 3 > image_type;

  image_type::SizeType size = region.GetSize();
  image_type::SpacingType voxel_size = in_volumetric_image->GetSpacing();
  _image* im = _createImage(size[0], size[1], size[2], 1,
                         voxel_size[0], voxel_size[1], voxel_size[2],
                         1, WK_FIXED, SGN_SIGNED);
  CGAL::Image_3 image(im);

【问题讨论】：

更新线程。

请运行 make V=1（或者可能是 VERBOSE=1）而不是 make，然后发布失败的命令。 CXX_FLAGS 不是应该添加链接器标志的位置。

添加了更新，为什么不应该出于好奇将链接器标志添加到 CXX_FLAGS 中？

我的意思是打印在上面的一行，您应该在其中看到 g++、-lCGAL 等。我怀疑该行不正确（可能是错误的顺序，尤其是在 Ubuntu 上时）。

我更新了，如果我发布了你不需要的东西，请告诉我，抱歉，然后大声笑

【参考方案1】：

您似乎未能正确设置 CGAL 的链接。这个thread 应该会有所帮助。只需链接到 ITK 而不是 VTK。
