cgal

I am trying to compile and link a C++ program that uses CGAL (http://www.cgal.org) on Mac OS X. The basic CGAL libraries were compiled with g++ 4.5 (using MacPorts). However a substantial part of the code is included in the header files and is compiled each time by icpc.

There is some kind of incompatibility between the compilers and/or the CGAL code, because a code that compiles and links perfectly with g++ 4.5, refuses to do so with icpc.

My options are as follows:

icpc -O3 -Wall -wd981 -D_GLIBCXX_USE_C99_FP_MACROS_DYNAMIC=1 -fp-model strict ...

and I get errors like

/opt/local/include/CGAL/Triangulation_ds_cell_base_3.h(50): error: only "()" is allowed as initializer for array member "CGAL::Triangulation_ds_cell_base_3::V"

Does anybody know how to fix this? Thanks.

What version of the Intelcompiler are you using? To me this looks like the same problem that is fixed in our 12.0 beta compiler (cq #139862) described here:

10/15/09
GNU array mem-initializers

g++ allows constructor mem-initializers for array members to have non-empty
initializers if the member is an array of a class type with a copy
constructor. We now emulate that in g++ mode.

struct A {
A();
A(const A&);
};
struct B {
A arr[2];
B(const B&p) : arr(p.arr) {} // Now allowed in GNU C++ mode
};

I am using version 11.1 (build 088) ...

As the preceding reponses indicate, g++ 4.5 is too recent to expect compatibility in icpc 11.1, and you may hope for improvement in icpc 12.0, which currently is in beta test.

Workarround:

Initialize the array one element at a time inside the construtor.

I will inform the forum users when the compiler with fixed available with fix for download.

The issue is fixed in latest Intel C++ composure 2001 XE (compiler 12.0). The composure is available for download from Intel registration and download center.
