[boost.Serialization V1.42.0] Question about BOOST_SERIALIZATION_SPLIT_FREE and non-public members
by gmkdroid 11 Aug '10

11 Aug '10

Hello, I'm trying to add Boost serialization to a class which has private data members. I'm using the "non-intrusive" free save/load split method. I've added "friend class boost::serialization::access;" to my class, but I still receive a "cannot access private member..." compiler error. How can I give the load/save functions friend access to my class? I'm using Visual Studio 2008 with Boost Version 1.42.0. Thanks, Glen

[accumulator] Undocumented rolling_window_plus1 accumulator
by vicente.botet 10 Aug '10

10 Aug '10

Hi, rolling_count depends on rolling_window_plus1which is not documented. rolling_count The rolling count is the current number of elements in the rolling window. Result Type std::size_t Depends On rolling_window_plus1 The same applies to rolling_sum. Could this documentation issue be managed?

[svn sandbox]
by Jeffrey Lee Hellrung, Jr. 10 Aug '10

10 Aug '10

When I try to SVN update the sandbox, I get the following error message: Update Can't create directory 'D:\boost-svn\boost-sandbox\statistics\support\boost\assign\v2\chain\aux': The directory name is invalid. It doesn't look so invalid. Is anyone else having any issues, or have any suggestions? I've tried "clean up", no help. I'm not an expert in SVN. Windows 7; TortoiseSVN 1.6.10, Build 19898 - 64 Bit (latest version AFAIK). Should I just recheckout the repo? (I'm sending a mailing list message first as checking out the repo takes a lot of bandwidth and time.) Thanks in advance, - Jeff

It will be Wednesday before I can start pulling the 1.44 beta together. In the meantime, does anyone have any serious issues we need to tackle before the beta? Thanks, --Beman

[1.44] Beta version of PDF docs available
by John Maddock 10 Aug '10

10 Aug '10

A PDF build of the docs for Boost-1.44-beta is now available from https://sourceforge.net/projects/boost/files/boost-docs/1.44.0/boost_1_44_p… if library authors would like to give their docs a once-over to check for SNAFU's that would be great. Regards, John.

Any interest in creating new CORBA IDL to C++ mapping?
by Johnny Willemsen 10 Aug '10

10 Aug '10

Hi all, We are talking with various users of TAO to see if we can create a new modern IDL to C++ mapping. The idea is to drop all old compilers which lead to the current mapping and make a new IDL to C++ mapping that is using the latest draft C++0x standard. We want to use full STL, shared_ptr, r-value, and everything else we could need. The idea is to prototype this first in TAO and than see if on the long term we can propose a new IDL to C++ V2 mapping to the OMG I did find some discussions on this list about 2 years ago, are people interested in this effort, any input is welcome.

[chrono] Compatibility issues with 1.44
by Roland Bock 10 Aug '10

10 Aug '10

Hi Vicente, do you have an estimate for an update of Boost.Chrono which is compatible with the upcoming 1.44 version of boost? I just tried the daily snapshot provided by Beman with the current Chrono zip: * Compilation of Boost.Chrono fails * Boost.Chrono zip contains changes for parts of Boost.Thread Are these still needed/compatible? Also (not related to 1.44, but also 1.41, at least), there are many warnings issued by the compiler. It seems to me that they are somehow related to the constructors of duration, but I haven't been able to figure them out. These also occur when compiling client code. A log file is attached. Generated on Ubuntu-10.4, 64bit, gcc-4.4.3 Regards, Roland PS: Snapshot: http://boost.cowic.de/rc/ (boost-posix-2010-08-02.tar.bz2) Boost.Chrono: http://www.boostpro.com/vault/index.php?&direction=0&order=&directory=System http://svn.boost.org/svn/boost/sandbox/chrono/libs/chrono/doc/html/index.ht….

[python] division operator in 3.1
by Trigve Siver 09 Aug '10

09 Aug '10

Hi, I've found bug in boost python with division operator. Division operator with custom types doesn't work with python 3.1. It is because there were some changes in this regard in python 3. I've created ticket with patch https://svn.boost.org/trac/boost/ticket/4497 . Can somebody look at it? Thanks Trigve
