Building for Visual Studio on Windows 8, I found a two problems: In Visual Studio 8.0 SP1 (Visual Studio 2005), there is a problem with iostreams/detail/path.hpp. Here's a excerpt from the build log: compile-c-c++ bin.v2\libs\iostreams\build\msvc-8.0\debug\link-static\runtime-link-static\file_descriptor.obj file_descriptor.cpp .\boost/iostreams/detail/path.hpp(123) : error C2535: 'path::sfinae<Path::external_string_type,boost::iostreams::detail::path&>::type boost::iostreams::detail::path::operator =(const Path &)' : member function already defined or declared .\boost/iostreams/detail/path.hpp(109) : see declaration of 'boost::iostreams::detail::path::operator =' libs\iostreams\src\file_descriptor.cpp(241) : warning C4800: 'int' : forcing value to bool 'true' or 'false' (performance warning) call "C:\Program Files\Microsoft Visual Studio 8\VC\vcvarsall.bat" x86 >nul cl /Zm800 -nologo @"bin.v2\libs\iostreams\build\msvc-8.0\debug\link-static\runtime-link-static\file_descriptor.obj.rsp" ...failed compile-c-c++ bin.v2\libs\iostreams\build\msvc-8.0\debug\link-static\runtime-link-static\file_descriptor.obj... compile-c-c++ bin.v2\libs\iostreams\build\msvc-8.0\debug\link-static\runtime-link-static\mapped_file.obj mapped_file.cpp .\boost/iostreams/detail/path.hpp(123) : error C2535: 'path::sfinae<Path::external_string_type,boost::iostreams::detail::path&>::type boost::iostreams::detail::path::operator =(const Path &)' : member function already defined or declared .\boost/iostreams/detail/path.hpp(109) : see declaration of 'boost::iostreams::detail::path::operator =' libs\iostreams\src\mapped_file.cpp(59) : warning C4244: 'return' : conversion from 'const boost::iostreams::stream_offset' to 'size_t', possible loss of data libs\iostreams\src\mapped_file.cpp(135) : warning C4244: 'initializing' : conversion from 'boost::iostreams::stream_offset' to 'LONG', possible loss of data libs\iostreams\src\mapped_file.cpp(136) : warning C4244: 'initializing' : conversion from 'boost::iostreams::stream_offset' to 'LONG', possible loss of data libs\iostreams\src\mapped_file.cpp(141) : warning C4244: '=' : conversion from 'boost::iostreams::stream_offset' to 'LONG', possible loss of data libs\iostreams\src\mapped_file.cpp(142) : warning C4244: '=' : conversion from 'boost::iostreams::stream_offset' to 'LONG', possible loss of data libs\iostreams\src\mapped_file.cpp(204) : warning C4244: 'initializing' : conversion from 'boost::iostreams::stream_offset' to 'LONG', possible loss of data libs\iostreams\src\mapped_file.cpp(205) : warning C4244: 'initializing' : conversion from 'boost::iostreams::stream_offset' to 'LONG', possible loss of data libs\iostreams\src\mapped_file.cpp(325) : warning C4244: 'argument' : conversion from 'boost::iostreams::stream_offset' to 'SIZE_T', possible loss of data call "C:\Program Files\Microsoft Visual Studio 8\VC\vcvarsall.bat" x86 >nul cl /Zm800 -nologo @"bin.v2\libs\iostreams\build\msvc-8.0\debug\link-static\runtime-link-static\mapped_file.obj.rsp" ...failed compile-c-c++ bin.v2\libs\iostreams\build\msvc-8.0\debug\link-static\runtime-link-static\mapped_file.obj... ...skipped <pbin.v2\libs\iostreams\build\msvc-8.0\debug\link-static\runtime-link-static>libboost_iostreams-vc80-sgd-1_47.lib for lack of <pbin.v2\libs\iostreams\build\msvc-8.0\debug\link-static\runtime-link-static>file_descriptor.obj... ...skipped <pstage\lib>libboost_iostreams-vc80-sgd-1_47.lib for lack of <pbin.v2\libs\iostreams\build\msvc-8.0\debug\link-static\runtime-link-static>libboost_iostreams-vc80-sgd-1_47.lib... This happens for all the different build types (debug/release,static/dynamic,runtime static/dynamic) for both 32&64 bit builds. The other error is that after the build, the copying of the boost_exception dll fails. Here's an example from the output: msvc.link.dll bin.v2\libs\exception\build\msvc-9.0\debug\threading-multi\boost_exception-vc90-mt-gd-1_47.dll msvc.manifest.dll bin.v2\libs\exception\build\msvc-9.0\debug\threading-multi\boost_exception-vc90-mt-gd-1_47.dll common.copy stage\lib\boost_exception-vc90-mt-gd-1_47.dll bin.v2\libs\exception\build\msvc-9.0\debug\threading-multi\boost_exception-vc90-mt-gd-1_47.dll 1 file(s) copied. common.copy stage\lib\boost_exception-vc90-mt-gd-1_47.lib The system cannot find the file specified. copy /b "bin.v2\libs\exception\build\msvc-9.0\debug\threading-multi\boost_exception-vc90-mt-gd-1_47.lib" + this-file-does-not-exist-A698EE7806899E69 "stage\lib\boost_exception-vc90-mt-gd-1_47.lib" ...failed common.copy stage\lib\boost_exception-vc90-mt-gd-1_47.lib... This happens for both the visual versions that get to this stage (VC9.0&VC10.0) and I assume the same would happen to 8.0 if it hadn't already errored out. I've posted the full error logs on my site (created by running the build a second time after it had already completed) if you're interested. http://boost.teeks99.com/misc/b_1_47_0_beta1-32bitlog.txt http://boost.teeks99.com/misc/b_1_47_0_beta1-64bitlog.txt Tom On Tue, Jun 21, 2011 at 9:34 AM, Beman Dawes <bdawes@acm.org> wrote:

Updated Libraries: Accumulators, Asio, Config, DateTime, Dynamic Bitset, Foreach, Function, Function Types, Graph, Iterator, Lexical Cast, Logic, Math, Meta State Machine, MultiIndex, Proto, Spirit, Tokenizer, Utility, Wave

For details of what's in the release, see http://beta.boost.org/users/news/version_1_47_0. Note that the links to files on this web page are for the final release - use the SourceForge link above to get the beta files.

There have been reports of build issues with MinGW/CGG and 64-bit Windows/VC++. These are being investigated and hopefully should be cleared up before the final release

Please download the beta, give it a try, and report any problems you encounter.

Thanks,
