| Hello,
The compiler was evidently the problem. I switched to LLVM GCC 4.2 and the compilation was successful with Boost 1.50 (haven't tried 1.53). This is just for C++, not Objective-C++ and the language is set to GNU99. On May 5, 2013, at 12:27 PM, Mikkel Islay wrote: HI Michael.
You are not telling us which compiler (frontend) and stdlib you are/have been using. Additionally, 1.50.0 is no longer current as you probably know. SInce Clang is not a primary test compiler for Boost, I could easily imagine problems, as C++11-implemenation have been a moving target for both Clang/libc++ and Boost. In fact, according to the 1.53.0 release notes Boost is tested against "Clang from Subversion".

However, this tool contains
#include "boost/math/special_functions.hpp"
and I updated my Boost installation to 1_50_0 from 1_44_0. After the update, and after changing "search header paths" accordingly, I got 20 Clang errors, internal to Boost, starting in cons_fwd.hpp. See arrows below:
#if !defined(BOOST_FUSION_CONS_FWD_HPP_INCLUDED) #define BOOST_FUSION_CONS_FWD_HPP_INCLUDED
namespace boost { namespace fusion { struct nil; <-- Declaration of anonymous struct must be a definition
template <typename Car, typename Cdr = nil> <-- Expected a type struct cons; }}
#endif
Xcode is behaving as though Boost itself were broken (which seems unlikely). Also, no variations on language or dialect seem to matter.
Any thoughts? Workarounds?
Thanks.
