问题
I have CGAL installed on my Mac OS X (10.8.4). I have successfully incorporated aspects of CGAL into previous C++ programs to compute the convex hull of a 3D point cloud. However, now I am trying to include other parts of CGAL for computing surface meshes, converting them to polyhedra, and so on. When I do that, the program compiles just fine, but then I receive linking errors that I don't understand.
Here is my linking command following compilation:
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
And here are the (rather verbose) linking errors I am receiving:

Am I missing a CGAL library in the linking command? Again, I had no trouble when I was using CGAL just to compute a convex hull, but this problem seems to have arisen now that I am trying to include surface meshing.
I will be happy to post relevant parts of the code if that will help, but at this point I don't know which parts would be relevant.
