[iostreams] Compilation errors with MSVC 8
When building CVS Boost with MSVC 8 beta 2 (http://lab.msdn.microsoft.com/vs2005/), it generated the errors below for iostreams. operations.hpp has a mixture of line endings, and symmetric_filter_adapter_impl is missing a return type, so I guess it's telling the truth! - KM F:\CVS\boost\boost/iostreams/operations.hpp : error C4335: Mac file format detected: please convert the source file to either DOS or UNIX format F:\CVS\boost\boost/type_traits/is_abstract.hpp(81) : warning C4800: 'unsigned int' : forcing value to bool 'true' or 'false' (performance warning) F:\CVS\boost\boost/type_traits/is_abstract.hpp(93) : see reference to class template instantiation 'boost::detail::is_abstract_imp2<T>' being compiled F:\CVS\boost\boost/iostreams/filter/symmetric_filter_adapter.hpp(303) : error C4430: missing type specifier - int assumed.

I'll check to make sure that this is fixed in the curent CVS. All the tests passed for me on VC8 before I checked in the most recent version.

Iostreams doesn't use is_abstract<>; this must be from another library.

I still haven't updated symmetric filter to handle non-blocking i/o, so it's currently broken. (I should say, I tried to updated it, but I haven't got it working yet) Best Regards, Jonathan
The warning from is_abstract.hpp may be because iostreams includes <boost/type_traits/is_convertible.hpp>. It's not your problem, but could be simply fixed by changing line 81 of is_abstract.hpp from this: BOOST_STATIC_ASSERT(sizeof(T)); to this: BOOST_STATIC_ASSERT(sizeof(T) != 0); - KM "Jonathan Turkanis" <technews@kangaroologic.com> wrote in message news:d5ilei$2t2$1@sea.gmane.org...

Right, I forgot is_convertible uses is_abstract now. I'll fix operations.hpp Jonathan

to this:
BOOST_STATIC_ASSERT(sizeof(T) != 0);
I'll get that fixed. Strangely the warning doesn't show up in any of the type_traits tests, and seems to be very specific to certain instantiations <shrug>. John.
