how to create smart pointer array?
by young 30 Jan '13

30 Jan '13

What is wrong with: boost::scoped_ptr<byte> buff[10]; for(int i=0; i<10; i++) { int size = 2*i + 100; buff[i] = boost::scoped_ptr<byte>(new byte[size]); } ... -- View this message in context: http://boost.2283326.n4.nabble.com/how-to-create-smart-pointer-array-tp4642… Sent from the Boost - Users mailing list archive at Nabble.com.

Building boost on Windows
by John Lilley 30 Jan '13

30 Jan '13

I am trying to figure out which libraries to build on Windows. I really only need "polygon" and "geometry". But what libraries these dependent on that also need to be built? I've tried to query which will be built and I'm not getting the expected results, for example: $ ./b2 --show-libraries --build-type=complete The following libraries require building: - chrono - context - date_time - exception - filesystem - graph - graph_parallel - iostreams - locale - math - mpi - program_options - python - random - regex - serialization - signals - system - test - thread - timer - wave Hmmmm... where is polygon and geometry? $ ./b2 --show-libraries --build-type=complete --with-geometry error: wrong library name 'geometry' in the --with-<library> option. Help please?

Custom library names
by John Lilley 30 Jan '13

30 Jan '13

How does one build boost with custom library/DLL names? There are two reason for this -- Our software simultaneously runs 32-bit and 64-bit versions of itself, and things are easier if the library names reflect this (e.g. inject _x64_ and _x86_ into the names). -- If we have customized Boost in any way, we want to give it a unique name so that it cannot possibly be incorrectly loaded by other code. Thanks, John Lilley

Mac OSX build options
by Tim Burgess 30 Jan '13

Hi, I'm trying to create an application for the Mac that is compatible with OSX 10.6 through 10.8, with both 32 and 64-bit support. How do I configure my Boost 1.50.0 to generate the appropriate binaries (I use serialisation, System and FileSystem), please? Best wishes. Tim Burgess Raised Bar Ltd.

C++11 Algorithms Book
by Algocoders . 30 Jan '13

30 Jan '13

The book "C++11 Algorithms Volume 1 : Using and Extending C++11, Boost and Beyond <http://www.algocoders.com/>" is published. *Table of Contents: http://www.algocoders.com/sites/default/files/toc_c%2B%2B11algorithms_vol1.… *<http://www.algocoders.com/sites/default/files/toc_c%2B%2B11algorithms_vol1.…> *Sample Chapter: http://www.algocoders.com/sites/default/files/chapter1_c%2B%2B11algorithms_… *<http://www.algocoders.com/sites/default/files/chapter1_c%2B%2B11algorithms_…> **<http://www.algocoders.com/sites/default/files/toc_c%2B%2B11algorithms_vol1.…> @Amazon : www.amazon.com/11-Algorithms-Volume-Extending-Beyond/dp/1482083396/<http://www.amazon.com/11-Algorithms-Volume-Extending-Beyond/dp/1482083396/> @Pothi.com (Indian Edition) : http://pothi.com/pothi/book/chandra-shekhar-kumar-c11-algorithms-volume-1<http://pothi.com/pothi/book/chandra-shekhar-kumar-c11-algorithms-volume-1> ** *Description* This book is vital to understand *algorithms* newly introduced in *C++11*with the help of practical examples illustrating *concepts*, *variations*, *customizations* and *correctness* with deep insight into internals with primary focus on *effective usage*. This book can be read by anyone having some experience in any higher level programming. Beginners in C++ will be able to learn basic concepts of C++11 algorithms with practical examples. Intermediate programmers in C++ will learn foundational aspect of C++11 algorithms in a pragmatic way. Expert programmers(aka C++ hackers) can enjoy interesting variations leading to future of C++11 algorithms(aka C++1y), Boost and beyond. This book(*Volume 1*) illustrates following algorithms: - *Numeric Algorithms* - Simulating for-loop iteration with iota - Customizing iota - Return Type of iota - Compile Time iota - Interesting variations of iota - *Quantifier Algorithms* - Universal Quantifier(*Predicate Satisfiability For All*) - Non-Existential Quantifier(*Predicate Satisfiability For None*) - Existential Quantifier(*Predicate Satisfiability For Some*) - Unique Quantifier(*Predicate Satisfiability For One*) - *Partition Algorithms* - Predicate Based Rearrangements - Partition Structure Validation - Bisection Algorithm - Group Partitions *Recommended Approach* Though this book can be read without reference to any other source, still we recommend our readers to keep a copy of the famous book *The C++ Standard Library, Second Edition : A Tutorial and Reference by Nicolai M. Josuttis* handy for gentle introduction to C++11 algorithms followed by diving into respective sections of our book for detailed information. In-depth treatment of foundational aspect of C++11 algorithms is covered in another book published by us Foundation of Algorithms in C++11, Volume 1(Revised Edition) : Using and Extending C++11, Boost and Beyond.<http://www.amazon.com/Foundation-Algorithms-Volume-Revised-Edition/dp/14819…> For more details, please visit the link : http://www.algocoders.com/article/books Enjoy Reading !

[Fusion] Associative Sequence not so associative
by TONGARI 30 Jan '13

30 Jan '13

Hi, I'd expect the associative sequence could be constructed and assigned with another sequence in different order. But it doesn't work, the src sequence must in the same order as the dst sequence defined. E.g. map<pair<K1, int>, pair<K2, int> > cannot take make_map<K2, K1>(1, 2). This is a bit disappointing :-( Does I miss something?

[Range][Iterator] iterate over an enumeration?
by John M. Dlugosz 29 Jan '13

29 Jan '13

I'd like to make it easy to do a BOOST_FOREACH for every value in an enumeration. I tried enum E { E_First, ⋯ , E_Last }; boost::counting_range(E_First, E_Last) but got compiler template barf. Can someone suggest a good way to do this?

serialization
by Larry E. Ramey 29 Jan '13

29 Jan '13

I'm having some trouble with the portable_binary_archive. When we serialze our classes via the text archive, they go in and out just fine. My simple test cases work great with the portable_binary_archive. However, in our production code, I get an input stream error exception tossed when I try to read a class that has STL elements in it. I have tried reordering includes and making sure the boost/serialization/list.hpp or whatever comes in front of the STL list class. Heck, I even put all those includes as the very 1st line of my test program to make sure they were included 1st. I am at a loss as the exception really doesn't tell me much, and the only thing I could figure out is that reordering the includes did in fact fix a few of these exceptions. (I still have one left... very annoying) Any ideas? I'd post the code, but it is very intertwined and difficult to distill a clean example. (and my stupid trail test does in fact work) Larry
