[multi_index] problems with initializer lists in Visual Studio 2013
by Joaquin M Lopez Munoz 20 Oct '13

20 Oct '13

I think this is related to the similar problem just discussed in connection with Boost.Unordered with the same compiler. The following struct employee { employee(int id_,std::string name_,int age_,int ssn_); // ... }; employee_set es8({{0,"Rose",40,4512},{1,"Mary",38,3345}, {2,"Jo",25,7102}}); gives me (see http://tinyurl.com/pg4fsln ) ..\libs\multi_index\test\test_copy_assignment.cpp(159) : error C2440: 'initializing' : cannot convert from 'initializer-list' to 'boost::multi_index::multi_index_container<[...]>' No constructor could take the source type, or constructor overload resolution was ambiguous and this es9={{0,"Rose",40,4512},{1,"Mary",38,3345},{2,"Jo",25,7102}, {0,"Rose",40,4512}}; results in ..\libs\multi_index\test\test_copy_assignment.cpp(162) : error C2593: 'operator =' is ambiguous D:\teeks99-10\boost\boost/multi_index_container.hpp(329): could be 'boost::multi_index::multi_index_container<[...]> &boost::multi_index::multi_index_container<[...]>::operator= (std::initializer_list<employee>)' D:\teeks99-10\boost\boost/multi_index_container.hpp(321): or 'boost::multi_index::multi_index_container<[...]> &boost::multi_index::multi_index_container<[...]>::operator = (boost::multi_index::multi_index_container<[...]> &&)' D:\teeks99-10\boost\boost/multi_index_container.hpp(313): or 'boost::multi_index::multi_index_container<[...]> &boost::multi_index::multi_index_container<[...]>::operator = (const boost::multi_index::multi_index_container<[...]> &)' while trying to match the argument list '(employee_set, initializer-list)' Is this the compiler's fault or mine? Any applicable library-side workarond? Thank you, Joaquín M López Muñoz Telefónica Digital

[Serialization] How to retrieve a class version in an archive without loading?
by nico 18 Oct '13

18 Oct '13

Hello. My question is about program rollback and the management of archive compatibility : let's say I saved on object of type T with my program in version 1.35 => archive.txt. If I roll back my program to a previous version (let say 1.30), I'd like to check (without trying to deserialize for performance issue) if T in 1.30 has the same "BOOST_CLASS_VERSION" as the object saved in archive.txt. *In brief : is there a way to retrieve the BOOST_CLASS_VERSION of T stored in the archive ?* I read boost code, but I didn't find a "quite direct" way to do that. It seems I must get cobject_id_vector of basic_iarchive_impl, but all this stuff is private. Is their another non-intrusive way to do it ? (By non-intrusive I mean : only using the boost public stuff, or at least with a simple inheritance to get protected member of base classes?). Thanks in advance. nicolas.

Re: [boost] Boost Serialization on Sun Solaris with rwtools7_std
by Brian Wood 18 Oct '13

From: Duc Tran: > That's not all errors, still have many. > Unfortunately, my company is unable to sponsor it. I have to do it myself. > Do you have any suggestions? I have alternative serialization approach. Unlike traditional library approach most of the code only runs on one platform as an on line code generator. I believe this makes porting to other platforms simpler than traditional approach. I'm willing to port my software to Solaris if you are interested. It should be easy. It would be nice to have someone to ask about Solaris install/admin questions. Additionally I'm willing to donate 15 hours/week for six months on a project that uses my software. -- Brian Ebenezer Enterprises http://webEbenezer.net

[mpi][type_traits] BOOST_BROKEN_COMPILER_TYPE_TRAITS_SPECIALIZATION macro missing
by Jeremiah Willcock 17 Oct '13

17 Oct '13

This macro was used in Boost.MPI, and it seems to no longer be defined in the Boost trunk, leading to compiler errors. Was it removed on purpose, and what should be done with the call to it in <boost/mpi/packed_iarchive.hpp>? -- Jeremiah Willcock

Extensive interdependencies in Boost
by Philip Bennefall 17 Oct '13

17 Oct '13

Hi all, I have been doing some tests with bcp recently, and the number of files I get for even the smallest header-only libraries (at least on the surface) is quite surprising to me. I know that not all files are used for compilation on a given platform, but I would still like to avoid putting 1253 files (11.7 MB) in my source tree just because I use a tiny part of Boost (boost/unordered_map.hpp in this case). I am wondering, will the effort that I have been reading about to modularize Boost, attempt to reduce some of these interdependencies? Or is the idea more about reducing the download size of the Boost distribution itself? Thanks in advance for any clarification. Kind regards, Philip Bennefall

[Correction] Extensive interdependencies in Boost
by Philip Bennefall 17 Oct '13

17 Oct '13

I'd like to correct some numbers in my recent post. I was looking at a directory containing the Boost files that had been put in a GIT repository so it had some files in it that were related to that. The true numbers are 1239 files (11.6 MB) when using bcp on boost/unordered_map.hpp. Sorry about the carelessness. Kind regards, Philip Bennefall

Boost Serialization on Sun Solaris with rwtools7_std
by Duc Tran 17 Oct '13

17 Oct '13

Hi All, My project is using rwtools7_std library on Sun Solaris. However, Boos Serialization needs stlport4 and these two libraries cannot work together. Does anyone use Boost on Sun Solaris with rwtools7_std before? Can I change Boost library to use rwtools7_std instead of stlport4? The reason is my project has to use rwtools7_std. Thank you. Dennis
