'CGAL :: Surface_mesh_parameterization :: get_error_message（int）'的多重定义

Question

我能够轻松地使用给定示例的CGAL表面网格参数化。这意味着CGAL已正确安装并且功能正常。 重现错误的方法：

1. 创建一个空的主文件
2. 创建一个对CGAL square_border_parametrize.cpp
进行适当修改的类文件
3. 在我执行cmake .和make之后，这就是输出

我无法找到_mm_getcsr()': /usr/local/include/CGAL/Interval_nt.h:202: multiple definition of的任何多重定义。我的CMakeLists.txt文件如下所示：

CGAL::Surface_mesh_parameterization::get_error_message(int)

Answer 1

快速修复：在inline前面的文件include / CGAL / Surface_mesh_parameterization / Error_code.h中写const char* get_error_message(int error_code)。

此修复程序位于此pull request中，现在已合并到CGAL-4.12中。
