[graph] Are you interested in the Route Inspection Problems and Vehicle Routing Problems?
by Ciro Santilli 14 Apr '14

14 Apr '14

Are you interested in implementations for the following problems: - Route Inspection Problems: http://en.wikipedia.org/wiki/Route_inspection_problem - classic: find shortest path for undirected graph possibly repeating edges. O(n^3). If Eulerian path exists, it is the min. - mixed graphs. NP-complete. AKA Chinese postman problem. - k-Chinese postman problem. N postmen. - Vehicle routing problem: http://en.wikipedia.org/wiki/Vehicle_routing_problem Generalization of Route Inspection. NP-complete. Many variants: edges have one ore more weights, and multiple constraints are possible: - carrying capacity of each truck - time to travel an edge and delivery windows for each edge All of those problems have extensive literature, and obvious practical applications. Why don't you use GitHub's Issue tracker instead of the mailing list? It integrates better with the code tracking and merge requests, and is much easier to search. That would greatly reduce contribution barriers to new devs.

[variant] Why no move emulation with Boost.Move for C++03?
by Andrzej Krzemienski 14 Apr '14

14 Apr '14

Hi, I am trying to figure out what the best way to enable move semantics in Boost.Optional. I tried to pick at how Boost.Variant does it. If I understand correctly, move operations are only defined if compiler supports rvalue references. I wonder why it doesn't use Boost.Move, which would enable move semantics even for compilers w/o rvalue references. Is there any reason for this (that I should also take into account for Boost.Optional)? Regards, &rzej

[BoostDocs] Need help with getting started with BoostDocs
by Andrzej Krzemienski 12 Apr '14

12 Apr '14

Hi Everyone, Perhaps someone in this list can help me generate html documentation from qbk sources. I am using MinGW on Windows and try to build the docs. I use the instructions form the following links. https://svn.boost.org/trac/boost/wiki/BoostDocs/GettingStarted http://www.boost.org/doc/libs/1_55_0/doc/html/quickbook/install.html#quickb… I am not sure if they are up to date. I downloaded all the necessary components, and when I try to run b2 on my doc folder, I get the following error messages: runtime error: file > file:///C:/_data/cpp/optional/boptional/quickbook/docbook-xsl/html/chunkfast.xsl > line 23 element variable > Recursive definition of chunks > runtime error: file > file:///C:/_data/cpp/optional/boptional/quickbook/docbook-xsl/html/chunkfast.xsl > line 32 element variable > Variable 'chunks' has not been declared. > xmlXPathCompiledEval: evaluation failed > runtime error: file > file:///C:/_data/cpp/optional/boptional/quickbook/docbook-xsl/html/chunkfast.xsl > line 32 element variable > Failed to evaluate the expression of variable 'div'. > I am not sure exactly where they are coming from. But they look like an error from the tool, rather than my qbk sources. Perhaps anyone here experienced a similar problem and knows a solution? Or perhaps there is a newer version of the instructions? Regards, &rzej

Application 0.4.6 with global_context
by Renato Forti 12 Apr '14

12 Apr '14

>> It actually provide a way to make a non-daemon application (mentionned in the part about launching the app). Yes, this is true! Officially the lib supports 2 kind (modes) of application. But user can define a new type, for sample this article, show how create a new application mode. In this case the mode is a apache httpd server module extension. http://www.codeproject.com/Articles/695937/Creating-a-New-Application-Mode

>> I find the idea, to have a cross-platform way of creating daemons/services, worthwhile. >> I would like to suggest that the name be changed from Application, which is far too generic for just creating a computer program, to something more appropriate, maybe 'daemon'. Thanks for your sugestion, i will think in that. >> I have never used the Mac, but does this extend to that OS ? Yes, on mac (OSX) a daemons is generated. Thanks

Status of Boost.Test library maintenance
by Kamil Witecki 11 Apr '14

11 Apr '14

Hello, I would like to ask what is current status of Boost.Test library. Looking at Trac there is number of open issues that are pending and not much is being done about these, even patches were proposed. Is the library not maintained anymore, what would be sad, or I just got false impression? In case of former what is the process of handing over maintenance of library so that it won't become abandoned? Pozdrawiam, Kamil Witecki.

Compile-time string comparing
by Anton Bikineev 11 Apr '14

11 Apr '14

Hi all. I think it's frequently asked question. If so, I'm sorry. Is there anything feature in Boost that allows to compare strings at compile-time? I know that it is easy-implemented with generalized constant expressions, but I'm primarily interested in compatibility of compilers. Thanks.

[align] Are you rewriting history with every push?
by Mostafa 11 Apr '14

11 Apr '14

Glen, Are you rewriting history or force pushing commits to "https://github.com/glenfe/align". I have a local repo set to track your remote and every time I pull to update to your new commits I get merge conflicts. In fact a new clone shows that the history for master has only one commit, the most recent one, when it should show at least three. Can you avoid doing this in the future? Thanks, Mostafa
