Undefined reference to `orient2d' / `orient3d' #135

Functions

       double orient2d(const double * pa, const double * pb, const double * pc);
       double orient3d(const double * pa, const double * pb, const double * pc, const double * pd);

are implemented if and only if CINOLIB_USES_EXACT_PREDICATES are not defined.

If CINOLIB_USES_EXACT_PREDICATES is defined, building errors occur : Undefined reference to orient2d' /orient3d'.

The implementation of exact predicates is external to cinolib. If you want to use them, you must define the symbol CINOLIB_USES_EXACT_PREDICATES at compilation time and include in your project the file cinolib/external/predicates/shewchuk.c
