I have removed the BOOST_STATIC_CONSTANT macro and made the substitution by hand but is there any workaround to make this work without modifying boost headers? On Mon, Dec 12, 2011 at 2:01 AM, Steven Watanabe wrote:

I am trying to use boost::iostreams. When I include boost/iostreams/filtering_streambuf.hpp (even if I don't declare any filtering_streambuf variables) I get the following compilation error: is_dereferencable.hpp: Parse Issue: Expected unqualified-id

The problem is in this code:

template <class T>   struct impl   {       static typename boost::remove_cv<T>::type& x;

      BOOST_STATIC_CONSTANT(           bool         , value = sizeof(is_dereferenceable_::check BOOST_PREVENT_MACRO_SUBSTITUTION(BOOST_comma(*x,0))) == 1       );   };

Compiler: Apple Clang 3.0, with -std=c++0x flag

Any help would be greatly appreciated.

This is because of Apple's evil #define check(x)

If possible, it's best to avoid the problematic Apple header. If not try either including the boost headers before the apple headers or undefining check before including boost:

#if defined(check) #undef check #endif

#include

Since the problematic code is in an implementation detail, I think we can fix this for the next version of boost by renaming 'check'.
