Cygwin CGAL 4.4/4.3 cygCGAL_Core-10.dll不工作

我是一个新手。我尝试在Cygwin下使用CGAL。 CGAL似乎已成功安装，但无法编译任何示例， 当我尝试“cmake”（成功）->“make”（失败） 他们向我扔炸弹

我完全不知道。

请帮帮我。非常感谢

我不能完全确定我的答案，但是当您在

/home/JIN/CGAL-4.4/examples/Core/

中配置示例时，使用CMake，您已经指定

/home/JIN/CGAL-4.4/config

作为

CGAL\u DIR

变量的值。该目录包含文件

CGALConfig.cmake

，该文件将在安装CGAL后使用。相反，您应该使用

/home/JIN/CGAL-4.4

作为

CGAL\u DIR

的值。该目录包含

CGALConfig.cmake

文件，必须使用该文件才能使用CGAL的就地生成树，而无需安装。

在构建CGAL库时，您的生成目录是什么？它是“/home/JIN/CGAL-4.4/”，对于最新的XCode 5.1，CGAL不起作用，我该怎么办？谢谢你，但问题仍然存在，我已经看到了很多问题的解决方案，由你，谢谢。。。。还有一个问题，我如何在XCode 5.1的MAC上使用CGAL，因为我更新了我的MAC，我不能再使用CGAL了……@ShengyeJin如果这不能解决你的问题，你为什么要接受我的答案？无论如何，谢谢你。XCode 5.1的clang编译器从CGAL-4.4开始就受到支持。如果您对该版本的XCode有任何问题，请在Stackoverflow上填写另一个问题，或发送到CGAL讨论邮件列表。谢谢您，Irineau，实际上我在CGAL讨论上问过，但似乎没有人对我的问题感兴趣。我将尝试CGAL4.4。
