9 years ago I can get it a bit farther if I switch to llvm-g++ compiler, and turn off
variadic templates, but still get a failure further on in SWIG generated code.
Interestingly(?) I get that same failure with the original compiler (clang++)
if I comment out the failing references to Line_3.

The code it doesn't like is the 'namespace swig' block from
CGAL_KernelPYTHON_wrap.cxx highlighted below between my vvvvv / ^^^^^:
...
SWIGINTERNINLINE PyObject *
SWIG_From_size_t (size_t value)
{
return SWIG_From_unsigned_SS_long (static_cast< unsigned long >(value));
}
vvvvvvvvvvvvvvvvvvvvv
namespace swig {
template <> struct traits<char > {
typedef pointer_category category;
static const char* type_name() { return"char"; }
};
}
^^^^^^^^^^^^^^^^
SWIGINTERN swig_type_info*
SWIG_pchar_descriptor(void)
{
static int init = 0;
static swig_type_info* info = 0;
if (!init) {
info = SWIG_TypeQuery("_p_char");
init = 1;
}
return info;
}
