Re: [boost] Boost Serialization of shared_ptr
by Kesseli Pascal 02 Jan '08

02 Jan '08

Hi again I just wanted to inform you that, using the newest library version 1.36, the serialization of all my objects worked perfectly fine :) . The only problem I encountered was a template error in <boost/serialization/utility.hpp> (included by <boost/serialization/map.hpp>). I had to add "#include <boost/mpl/and.hpp>" there for this to compile properly. Anyways, thanks again for your help :) . Best regards Kessi No virus found in this outgoing message.

Re: [boost] old style streams support?
by Eames, Andrew 02 Jan '08

02 Jan '08

I didn't get any replies to this (not that I expect anyone to be interested in my crufty old compiler anyway J ). While rooting around in the boost 1.34.1 source I found detail/template_streams.hpp which seems to be the solution I am looking for but this doesn't appear to be used very much in other parts of boost. How should I proceed here? I can update the pieces of boost I need to use these macros - can I commit these changes (post 1.35)? - should I ask someone else to? Am I on my own? Thanks Andrew From: Eames, Andrew Sent: Friday, December 21, 2007 11:52 AM To: 'boost(a)lists.boost.org' Subject: old style streams support? Hi, My DSP compiler comes with an ancient version of STL which only has old-style streams support (non templated streambuf etc.). It seems that in order to use some parts of boost that use streams, I would need to either modify boost to allow old style streams or use something like STLPort to get a more modern version of STL (My compiler vendor is unlikely to provide me with a more modern version). Using STLPort comes with its own porting issues - I have tried it briefly and it could probably be made to work but it would definitely require some modification. Is there any interest in supporting old-style streams in boost? Andrew

[ptr_container] [serialization] Header dependency between ptr_vector and serialization
by Phil Endecott 02 Jan '08

02 Jan '08

Dear All, It seems that the ptr_vector headers include some serialization headers. I've discovered this because on my Debian system I have installed their libboost-dev package, which includes the header-only libraries such as ptr_container, but not libboost-serialization-dev. Alexey Khudyakov has already filed a Debian bug report: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=457654 So, what should be going on here? My guess is that a subset of the serialization headers should be included in Debian's header-only libboost-dev package, so that ptr_vector can compile. I'm not sure if they get any hints for their partitioning from the Boost build system; if they do, then it should be fixed there. Any thoughts? Phil.

[mpl][docs]map insert doc: what's t?
by Larry Evans 01 Jan '08

01 Jan '08

On: http://www.boost.org/libs/mpl/doc/refmanual/map.html there's the following row in the "Expression Semantics" table: insert<m,x>::type A new map equivalent to m except that at< t, key_type<m,x>::type >::type is identical to value_type<m,x>::type. which is confusing because the 't' in at< t, key_type<m,x>::type >::type doesn't occur in the 1st column of that row. Should it read: insert<m,x>::type A new map, t, equivalent to m except that at< t, key_type<x>::type >::type is identical to value_type<x>::type. ? I'm assuming that x is an mpl::pair<k,v>, for some key, k, and value, v.

A question regarding serialization lib
by Arunava Saha 30 Dec '07

30 Dec '07

Dear experts, I am using boost serialization library to serialize a huge database (has a lot of stl containers, shared pointers etc. ). I have a general question regarding serialization lib of boost. Suppose I have serialized a database in text format (say, text1.doc), cleared the existing database, import the exported one back and re-export (say, text2.doc). Now, should I see any difference between text1.doc and text2.doc? Actually I am seeing some difference. If I shouldn't, can someone point me to the common mistakes one can do for which it differences can take place? Thanks in advance, Arunava.

[review] Boost.Functional/Factory library result : accepted
by John Torjo 30 Dec '07

30 Dec '07

Hi all, The Boost.Functional/Factory library, submitted by Tobias Schwinger has been *accepted*. Thanks to all reviewers and to all who contributed before the review! We've received 3 reviews, all positive: Larry Evans, Stejan Rajko, and Detlef Wilkening*. *Suggested improvements * *Implementation *- Allocator should be inherited *Docs *- should include some hint about how to overcome the Lvalue constraint on the arguments that's mentioned in the docs: a0...aN - argument LValues to a constructor of T - separate the two templates (factory and value_factory) a little bit more in the introduction so that it reinforces that they are different in usage - better motivation - more detailed examples * note: I consider Detlef's review positive, even though he wanted 3 extensions (in light of Tobias's answer): - Better name for factory: factory_ptr or factory_pointer. - Better motivation for beginners in the docu. - Extension with a third template parameter for e.g. 2 phase construcion. Best, John -- http://John.Torjo.com -- C++ expert ... call me only if you want things done right

boost/config/stdlib/libstdcpp3.hpp: Private or public header file?
by Jens Seidel 29 Dec '07

29 Dec '07

Hi, I noticed that I get errors if I try to include boost/config/stdlib/libstdcpp3.hpp as some macros are redefined unconditionally. So it contains for example #ifdef __GLIBCXX__ #define BOOST_STDLIB "GNU libstdc++ version " BOOST_STRINGIZE(__GLIBCXX__) #else #define BOOST_STDLIB "GNU libstdc++ version " BOOST_STRINGIZE(__GLIBCPP__) #endif but boost/config/suffix.hpp defines it as well. This causes trouble if suffix.hpp is included and after it libstdcpp3.hpp. Since both files are not located in detail/ I consider both as public header files and it should be OK to include both (libstdcpp3.hpp will probably only included indirectly). Is it wrong to include boost/config/suffix.hpp? Jens
