Macports cgal不工作！我如何解決它？

這是我在CGAL主頁上找到的一個基本例子。我試圖編譯如下：Macports cgal不工作！我如何解決它？

1 #include <iostream>                
    2 #include <CGAL/Exact_predicates_inexact_constructions_kernel.h>     
    3 #include <CGAL/convex_hull_2.h>             
    4                     
    5 typedef CGAL::Exact_predicates_inexact_constructions_kernel K;     
    6 typedef K::Point_2 Point_2;              
    7                     
    8 int main()                  
    9 {                    
10 Point_2 points[5] = { Point_2(0,0), Point_2(10,0), Point_2(10,10), Point_2(6,5), Point_2(4,1) }; 
11 Point_2 result[5];                
12                     
13 Point_2 *ptr = CGAL::convex_hull_2(points, points+5, result);    
14 std::cout << ptr - result << " points on the convex hull" << std::endl;  
15 return 0;                  
16 }

，但我得到這個錯誤：

我的MacPorts使用安裝CGAL。有沒有人知道這可能是錯誤的？

請將您的代碼內聯，而不是在pastebin上發佈。錯誤也是一樣。 – 2012-02-07 19:34:15

對不起，我不知道它支持內聯代碼。讓我知道如果你知道如何解決它... – newDelete 2012-02-07 20:19:59

它可能是編譯器用於macport來構建CGAL不是用於編譯您的示例。你的錯誤是你的編譯器不支持variadic模板參數，而CGAL是用它們配置的。 – sloriot 2012-02-08 06:50:36

實際上，它看起來像編譯器或編譯器選項在構建CGAL和編譯CGAL時使用的不匹配。這可能是macports沒有幫助，我安裝CGAL時比macports運行更幸運。
