Re: [boost] Boost Serialization of shared_ptr

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.
