我在Mac OS X（10.8.4）上安装了CGAL。我已成功将CGAL的各个方面合并到以前的C ++程序中，以计算3D点云的凸包。但是，现在我试图包含CGAL的其他部分来计算表面网格，将它们转换为多面体，等等。当我这样做时，程序编译得很好，但后来我收到了我不理解的链接错误。
这是编译后的链接命令：
c ++ -O2 -I / usr / local / include -I / usr / include -I / opt / local / include -o / Users / bullard / ShapeMetrology / Particle / bin / diffgeom diffgeom.a -L / usr / local / lib -L / usr / lib -L / opt / local / lib -lboost_math_c99 -lm -lCGAL -lCGAL_Core -lCGAL_ImageIO -lgmp
以下是我收到的（相当冗长的）链接错误：

我在链接命令中错过了一个CGAL库吗？再次，当我使用CGAL计算凸包时，我没有遇到任何麻烦，但是现在这个问题似乎已经出现，我试图包括表面网格划分。
我很乐意发布代码的相关部分，如果这会有所帮助，但在这一点上我不知道哪些部分是相关的。
