I guess I was wrong. It seems to have worked for me in some cases, but your error clearly looks like a failure to find an installed bitten. Please try: cd C:\temp\regression\bitten-trunk\ c:\Python25\python setup.py install and then launch your slave again. Thanks, -- Dave Abrahams Boost Consulting http://www.boost-consulting.com

Starting Boost.Ruby: Questions / Comments
by Jason Roelofs 09 Dec '07

09 Dec '07

Hey all, So after many hours of research, attempts at wrapping up code with SWIG and what not, I've decided to attempt taking the ideas from Boost.Python and luabind and make a Ruby version. I know about the Langbinding project, but as there is very little there, details are scarce and I haven't received a response for a post I made there, I'm going to go my own way. When (if) Langbinding picks up again I'll definitely look at offering help to building a Ruby backend, but until then I might as well just build Boost.Ruby to learn what's needed. That said, is there anyone here who's started a similar project, or knows of one? I've done searching through this list, and through the general web and have found nothing. This will be my first time really using Boost and I look forward to both learning about and hopefully contributing to this excellent library. Also, if there is any recommended reading, or lessons learned that I should read (that isn't easily accessible through Boost documentation), I'd also appreciate that. Jason Roelofs

[1.35.0] branches/release open for known-good merges
by Beman Dawes 09 Dec '07

09 Dec '07

Until further notice, branches/release is open for known-good merges. "known-good" means changes that are already passing trunk regression tests, or are in files like documentation that have no effect on testing. Thus if you make a bug fix in trunk, wait a day or two before committing a merge of the fix to branches/release and look at the regression test results before you commit. Make sure in particularly the change doesn't break other libraries. Thanks, --Beman

Serialization and dynamic "fallback" to base classes
by Edgars Irmejs 08 Dec '07

08 Dec '07

Boost Serialization library provides a great solution for serializing derived classes by pointers to base classes, but I'm concerned with a simple use case: The program is being used on two computers "A" and "B" where "A" sends data to "B" by the means of serialization. At some upgrade of the program a serialized class "bus" is complemented with a derived class "big_bus". Only computer "A" gets the new version. I don't want the old version on "B" to dismiss a received "big_bus" object from "A", I need to convert it into a "bus" class object. It is sometimes much more useful to process the "big_bus" as a "bus" than not to process at all. I can assure serialization of each derivation starts with the serialization of the base class. I'm also ready to cope with the overhead of storing parent class information within the information about the derived classes. And it's ok if multiple inheritance is out of the question. Is there a pattern, a proposed solution to allow this dynamic "fallback" to base classes?

boost directory structure
by Fernando Cacciola 07 Dec '07

07 Dec '07

Is this fixed? or can it differ on some patform? I ask because CMake's FindBoost module is looking at the wrong include and lib places (wrong for the default structure), but maybe that's the correct one on some linux or so. TIA Fernando
