[typeof] BOOST_AUTO and move semantic emulation
by vicente.botet 03 Feb '09

03 Feb '09

Hi, given T&& f(); which is the type of v in auto v = f(); Is there any plan to adapt Boost.Typeof with move semantics, so the following works? BOOST_TYPEOF_REGISTER_TEMPLATE(boost::detail::thread_move_t, 1) BOOST_TYPEOF_REGISTER(T) boost::detail::thread_move_t<T> f(); BOOST_AUTO(v, f()); Thanks, Vicente

[1.38][flyweight] permission to merge to release
by JOAQUIN M. LOPEZ MUÑOZ 02 Feb '09

02 Feb '09

Hi, I've just commited the following trivial fix to the trunk: https://svn.boost.org/trac/boost/changeset/50974 which only adds a missing std:: to a call to strcpy. The fix hasn't still cycled trough the trunk regression testers, but I've tested it locally with MSVC++ 8.0 and GCC 3.4.4 and everything's fine. Can I merge to release now? Do I wait for a trunk test cycle? No permission at all? Thank you, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

[LibrariesUnderConstruction] Thanks!
by Christophe Henry 02 Feb '09

Hi, I realized this morning that I didn't add Msm to the LibrariesUnderConstruction Wiki page. And what do I see? Already done! And with description and link to the Vault! I have no idea who did it, but I want to thank him! And offer him a bottle of Bordeaux wine (if I manage to pass it through the customs ;-) ) at the next occasion (Aspen?). Thanks a lot, Christophe

[accumulators] why not operator+=?

A nit perhaps, but why not overload += to process samples?

What happens when a Boost library is unmaintained?
by Peter Simons 02 Feb '09

02 Feb '09

Hi, suppose that an accepted and officially distributed Boost library has become unmaintained, meaning that a) the code is not developed any further, b) reported bugs are not fixed, confirmed, or otherwise responded to, and c) questions on the mailing list aren't answered, then what is the procedure to deal with that situation? Take care, Peter

Boost::Graph --- why does this program not compile?
by Oliver Kullmann 02 Feb '09

02 Feb '09

Hello, in parallel to trying to get 1_34_1 compiling again, I'll also try to understand why the code won't compile with 1_37_0. Now I found the following program which actually compiles neither with 1_34_1 nor with 1_37_0, but it should: ------------------- #include <utility> #include <vector> #include <boost/graph/adjacency_list.hpp> template <class Graph> inline Graph orthogonality_relation() { typedef std::pair<unsigned int, unsigned int> edge_type; std::vector<edge_type> ev; Graph g(ev.begin(), ev.end(), 0, 0); return g; } typedef boost::adjacency_list<boost::listS, boost::vecS, boost::undirectedS> UndirectedGraph; int main () { orthogonality_relation<UndirectedGraph>(); } ------------------- The abbreviated error-message from gcc (version 4.1.2) is: Error.cpp:17: instantiated from here Boost/1_37_0+4.1.2/include/boost-1_37_0/boost/graph/detail/adjacency_list.hpp:2113: error: invalid type argument of ‘unary *’ where line 17 is the last line of the main-function.

Re: [boost] Review process question
by Christophe Henry 02 Feb '09

> It is enough to specify which revision that is to be reviewed. Is it possible to change it after the submission request? It would allow me to make some bugfixes (if necessary) while being in the queue.

Review process question
by Christophe Henry 02 Feb '09

02 Feb '09

Hi, I just read the submission process page and being a bit new to this, I have some questions. The page states that all the files making up a library should be compressed into a zip file and posted in the Vault upon submission. - Wouldn't it be better to use the Sandbox for this? After all, this seems to be quite the goal of SVN. It would also allow bugfixes who might appear between submission and review. This leads us to the next question. - Does it mean that while the library is in the review queue, it cannot be changed? I understand this is a long process and it would be nice to correct problems which might appear during this time. It would be also sad to stop development too early. Sorry if I ask stuff which is already broadly known. Christophe

Hi Vicente, Then you are the winner of a bottle of wine. And no I will definitely not forget :) Thank you again, it was very nice from you to even look into the Msm documentation to add a description! BTW, this wiki page is very useful, great idea! Christophe
