There is a error in the file licence_info.cpp under tools\bcp
by Huifeng Shen 20 Oct '05

The original line 18 is (pay attention the correspond the parentheses) "Copyright|\\(c\\)|? I compile bcp with vc71 toolset and fails. I change this line with "Copyright|\\(c\\)|?" It's OK. I also check the code in the CVS, This error is not corrected.

Re: [Boost-users] [MultiIndex] Key extraction from a base member

Hello Bruno, thanks for using Boost.MultiIndex! ----- Mensaje original ----- De: Bruno Martínez <br1(a)internet.com.uy> Fecha: Miércoles, Octubre 19, 2005 10:46 pm Asunto: [Boost-users] [MultiIndex] Key extraction from a base member > Hi. > > I have the following problem with MultiIndex.

Actually enable_if only works for highly compliant compilers, so I'll have to resort to some uglier mechanism, but it can be done. This is planned to be solved (or added as a new feature, if you wish) in Boost 1.34. The problem was first brought to my attention in http://tinyurl.com/dnfzs. In the meantime I'm afraid you are forced to write your own key extractor (which is trivial, in any case.) Best regards, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

question about subgraphs
by Jeffrey Holle 19 Oct '05

19 Oct '05

I am using boost 1.33.0. I want to use a subgraph to represent a spanning tree of a graph. This application requires adding and deleteing edges to just the tree and not the underlining graph though. Note that this wouldn't violate the requirements of a subgraph, a spanning tree contains all the vertices, and a subset of the edges of the underlining graph. Is it possible to do this, maybe through inheritance?

[MultiIndex] Key extraction from a base member
by Bruno Martínez 19 Oct '05

19 Oct '05

Hi. I have the following problem with MultiIndex. For struct Base { int id; }; struct Der : Base { }; I can't make a key extractor. This way typedef multi_index_container< Der, indexed_by< ordered_unique<member<Der, int, &Der::id> > >Set; doesn't work because &Der::id is of type pointer to member of Base. This other typedef multi_index_container< Der, indexed_by< ordered_unique<member<Base, int, &Base::id> > >Set; doesn't work because of the ChainedPtr overloads in member. I tried casting &Der::id to the appropiate type, but couldn't make it work. Maybe the solution is to put some enable_ifs in member. Regards, Bruno

Why can't we use boost::any for serialization ? Isn't there any work around to make this work ???

[Serialization]class(type) name in xml archive?
by Sean Huang 19 Oct '05

19 Oct '05

Is it possible to add class(type) name in xml archive? It would be a big help when looking at the xml output (yes, we want to display those files). for example (from demo.xml): <s type="bus_schedule" class_id="0" tracking_level="0" version="2"> ^^^^^^^^^^^^^^^^^ Thanks, Sean

Boost Birds of Feather @ OOPSLA 05?
by Jeff Garland 18 Oct '05

18 Oct '05

All - I'm going to be in San Diego @ OOPSLA next week and I'm wondering if any Boost users and developers would be interested in getting together for a BOF one evening. Obvious topic of discussion is all things Boost/C++/TR2. Right now I'm thinking Tuesday night would be a good time. Let me know if there is interest and I'll set this up. Jeff Note, I cross-posted to the user and developer list b/c the idea is this would be open to everyone with an interest in Boost.

FW: custom iterator_adaptor::pointer
by Sigg Christian 18 Oct '05

18 Oct '05

Dear boosters, I'm trying to figure out why there is no way to define the iterator_adaptor's pointer type. I'm trying to write an iterator that concurrently accesses two containers, but the interface should look like it's only one container. Therefore, it is necessary to write my own value, reference and pointer type. However, the iterator_adaptors pointer type is always value*. Is it save to just overload the pointer typedef and reimplement operator->()? I'm not too much of a c++ expert, so if anyone could comment on that, I would greatly appreciate it. Christian

Any way to use boost lib standalone?
by Hendrik Bock 18 Oct '05

18 Oct '05

Hello there! I have searched the boost-users mailing-list for quite some time, but found no answer to my question: Is there a possibility to separate a library from the rest of boost? I only want to use the regexp library of boost and i have to include all related header-files plus libs into our company-cvs. Till now i wasn't able to find out, which *.hpp files are needed by boost and which ones aren't. Kind regards, Hendrik Bock
