I am trying to compile some C++ code which uses the CGAL library on OS X Lion. I downloaded and installed on some directory the CGAL library. Then, when I try to compile the code, using "make";
triangulation.h:18:64: error: CGAL/Exact_predicates_inexact_constructions_kernel.h: No such file or directory
which means it does not find the CGAL lib. I look at the Makefile, and I see that it compiles using the flag
-lCGAL
Wondering how to solve this, I guess I could pass the information about the placement of my compiled library to this variable, but I do not how. I tried with export and so on but it does not recognize it, any hints?
The error message doesn't mean the library isn't found; it means a header file isn't found. The -lCGAL switch does indeed refer to the library. You're going to need a -IXXXXX switch added on to CFLAGS, where XXXXX is the path to the directory containing the CGAL directory which in turn contains Exact_predicates_inexact_constructions_kernel.h .
