boost-users [shared_array] comparing the value.
by chun ping wang 25 Oct '07

25 Oct '07

Hi I notice boost shared_array compares the pointer address not the pointer themselves. What would be the best way to compare the actual value of boost shared_array. 1.) shared_array<T> a; shared_array<T> b; 1.) return (a.len == b.len && (memcmp(a, b, len) == 0)); or 2.) if (a.len != b.len) return false; for (ptrdiff_t i = 0; i != a.len; ++i) if(a[i] != b[i]) return false; One that works ALL the times.

Building boost::system
by Simon Pickles 25 Oct '07

25 Oct '07

Hi, Since the new update of boost::asio, I need to build boost::system. I built it using bjam in the boost/system/build directory, and it built: boost_system_vc80-gd-1_34_1.lib but my compiler needs: libboost_system-vc80-mt-gd-1_34_1.lib I'm not sure what the difference between the boost and libboost version, but I know the mt is multithreaded.... Can anyone advise? Thanks Si

Boost Problem
by question boost 25 Oct '07

25 Oct '07

Hi, my program makes use of Boost(Code Blocks). The arrangement of my files is the following: 1 in the directory of the source files of my program there is the directory "boost" containing the following directories: "filesystem", "config", "iterator","range","detail", "mpl", "preprocessor", "tools" and the file boost-build.jam. 2 The file that makes use of boost in my project contains the following lines: #include <string> using namespace std; #include "boost\filesystem\path.hpp" #include "boost\filesystem\operations.hpp" using namespace boost::filesystem; At compilation I get the message :"boost/preprocessor/config/config.hpp" no such file or directory and several other similar messages about other files of the same directory and about other files of the "mpl" directory. What goes wrong?

Thread Group fails to run
by Apostolos Apostolidis 25 Oct '07

25 Oct '07

Hi all. I have developed some code allowing a thread group of 500 threads to run. However, as soon as the 381st thread is spawned, I get the following runtime error : terminate called after throwing an instance of 'boost::thread_resource_error' what(): boost::thread_resource_error The Boost documentation does not clarify the nature of the error, so I was wondering if anyone can help me out here. The (simple) program code follows. #include <boost/thread/mutex.hpp> #include <boost/thread/thread.hpp> #include <boost/bind.hpp> using namespace std; boost::mutex io_mutex; void foo(int i) { boost::mutex::scoped_lock lock(io_mutex); cout << i << endl; } int main(int argc, char *arvg[]) { boost::thread_group tg; for(int i = 0;i < 500;i++) tg.create_thread(boost::bind(&foo,i)); tg.join_all(); }

Using mpl::remove with template paramter
by spider tong 25 Oct '07

25 Oct '07

Hi all, I'm trying to use mpl::remove to do some processing with a template parameter, like this template<typename T0, typename T1=null_type, ... typename Tn=null_type> struct my_class { typedef mpl::vector<T0, T1,...Tn> my_vector; typedef mpl::remove<my_vector, null_type>::type my_non_vector; //failed here }; Compiler report that my_vector is not derive from my_class<T0, T1,..Tn>. It seems that 'remove' would test the sequence at once, and my_vector still un_known yet, so it fails, is this guess right? //-------------------------------------------------------------------------- And I've tried this fusion too: teypdef vector<Class1, Class2, null_type, null_type> vec; vec v; fusion::for_each<v, print>; it seems that it iterate 4 times, not 2, even size(vec) return 2. It seems only evaluate will skip null_type, iterate will go through all member, is my guess right? Best Regards Spider

Re: [Boost-users] Request to know about "dynamic expression evaluation"

Hi, You recommended checking the "expression templates". However, expression templates (xpressive) provides the means of parsing the input expressions in to tokens. It does not have the support for evaluating these expressions. --- please correct me if I'm wrong.

Compiling 1.34.1 on OpenSUSE 10.3
by Ruediger Berlich 25 Oct '07

25 Oct '07

Hi there, OpenSUSE 10.3 is still delivered with Boost 1.33.1 . Hence I've downloaded Boost 1.34.1 and tried to compile it. I ran the configure script and then make. The resulting bjam immediately dies with an error: ./tools/jam/src/bin.linuxx86/bjam --user-config=user-config.jam /bin/sh: line 1: 2090 Speicherzugriffsfehler ./tools/jam/src/bin.linuxx86/bjam --user-config=user-config.jam "Speicherzugriffsfehler" means "memory access violation". This is on a Pentium-D dual-core system (4GB main memory) running with a 32-bit Linux kernel 2.6.22, g++ 4.2.1 . Does anyone have experience with this constellation ? Compilation of 1.34 worked fine on OpenSUSE 10.2 . Thanks and best regards, Ruediger

Question about versioning of serialization
by Fred Lupien 24 Oct '07

24 Oct '07

Hello, we are currently implementing serialization versioning using boost and I am curious to know if their is a way to support a changing class hierarchy. Let's say C derives from A for a while and then a change requires C to derive from B instead, which derives from A. Is it possible to support such a change provided we know what default values are needed for the new class? I tried and even if don't serialize anything in class C I get stream errors because I believe boost saves some base info for each class. When it tries to reload those value from a old stream, obviously it desynchronizes it because the values are not in the stream. So is their a way around this? Also is it possible to support the removal of a class. If, for exemple C derives from B which in turn derives from A and suddenly B is removed. Is their a way to deal with this without invalidating all previously saved data? Thank you for your help! -- Frédérick Martel-Lupien Étudiant en Génie Informatique Université de Sherbrooke fred.lupien(a)gmail.com

dereferencing type-punned pointer in function_base under gcc-4.3
by Benoit Hudson 24 Oct '07

24 Oct '07

I'm trying to make sure my code compiles under gcc-4.3 before that compiler comes out. I'm currently stuck on an error it reports in boost, version 1.34.1 (which I downloaded seconds ago; error was also present in 1.34.0): In file included from ../boost/function/detail/prologue.hpp:16, from ../boost/function.hpp:22, from ../boost/iterator/transform_iterator.hpp:10, from [my code]: ../boost/function/function_base.hpp: In member function 'const std::type_info& boost::function_base::target_type() const': ../boost/function/function_base.hpp:485: error: dereferencing type-punned pointer will break strict-aliasing rules I don't understand how there's any type-punning going on at line 485, although to my untrained eye it looks a lot like it's returning a ref to a temporary. A couple lines later looks only very slightly fishier, but still shouldn't be breaking any aliasing rules. So I leave it to the experts to figure out what's going on here. -- Benoît

[program_options] Translating messages to another language
by Pavel Syomin 24 Oct '07

24 Oct '07

Hi to all! I am writing some application that uses program_options. This application interacts with user using non-english language. Is there any way to translate "what" messages from exceptions to another language? At now I found only one way (rather hack :) ): static void store(const basic_parsed_options<char> &options, variables_map &variables) { try { program_options::store(options, variables); } catch(unknown_option &error) { const char *what = error.what(); static const char prefix[] = "unknown option "; if(!strncmp(what, prefix, sizeof(prefix) - 1)) throw logic_error("Неизвестная опция: " + string(what + sizeof(prefix) - 1)); throw logic_error("Неверный формат командной строки"); } } Another way is to redefine function invalid_command_line_syntax::error_message(), but in such case we can translate only some messages.

Problem using Boost Graph Library - Python Bindings

24 Oct '07

Hello all, I have just installed the Boost Graph Library - Python Bindings. Everything seemed to be ok, I can read a graph from the example "mst.dot" file and from my own ".dot" files, I can write them back to a file. However, when I try the example script (at the end of the following page: http://www.osl.iu.edu/~dgregor/bgl-python/) -------------------------------------------------------------------- import boost.graph as bgl # Load a graph from the GraphViz file 'mst.dot' graph = bgl.Graph.read_graphviz('mst.dot') # Convert the weight into floating-point values weight = graph.convert_property_map(graph.edge_properties['weight'], 'float') ... etc ------------------------------------------------------------------- it stops at the third line with the following error: ---------------------------------------------------------------------------- Traceback (most recent call last): File "<pyshell#17>", line 1, in <module> weight = graph.convert_property_map(graph.edge_properties['weight'],'float') KeyError: 'weight' ------------------------------------------------------------------------ I receive the same error message if I write only: graph.edge_properties['weight'] The content of the example mst.dot file is: -------------------------------------------------- graph G { A -- C [weight="1.0"] B -- D [weight="1.0"] B -- E [weight="2.0"] C -- B [weight="7.0"] C -- D [weight="3.0"] D -- E [weight="1.0"] E -- A [weight="1.0"] E -- B [weight="1.0"] } -------------------------------------------------- Does any one have any idea about the source of this error. Thanks a lot in advance, Camilo

Boost features targeting Banking Application - Please share your thoughts!!!!!!
by jayaram.x.ganapathy＠jpmorgan.com 23 Oct '07

23 Oct '07

Hi, I am a C++/JAVA developer. Today someone was saying it is time to migrate from legacy C++ systems to JAVA. I love C++ :-( The trend in banking industry or belief in Banking projects is C++ is outdated and JAVA is the solution. One reason I felt is lack of open source enterprise level middlewares for C++. For java we have many EJB servers, Spring framework is there. Will boost be building libraries which will help to build enterprise level application? Some API's like iBatis, hibernate etc. Something similar to JSP and Tomcat equivalent? I think those will attract more developers to C++. Boost community is doing an excellent job. But how much is the industry going to use? Regards, Jayaram ----------------------------------------- This communication is for informational purposes only.

Thanks, Oleg. 1>------ Rebuild All started: Project: ExampleXmlSave, Configuration: Release x64 ------ 1>Deleting intermediate and output files for project 'ExampleXmlSave', configuration 'Release|x64' 1>Compiling... 1>stdafx.cpp 1>Compiling... 1>ExampleXmlSave.cpp 1>C:\WORK\STL\boost\boost_1_34_1\boost/config/abi_prefix.hpp(19) : warning C4103: 'c:\work\stl\boost\boost_1_34_1\boost\config\abi_prefix.hpp' : alignment changed after including header, may be due to missing #pragma pack(pop) 1>C:\WORK\STL\boost\boost_1_34_1\boost/archive/detail/abi_prefix.hpp(11) : warning C4103: 'c:\work\stl\boost\boost_1_34_1\boost\archive\detail\abi_prefix.hpp' : alignment changed after including header, may be due to missing #pragma pack(pop) 1>C:\WORK\STL\boost\boost_1_34_1\boost/archive/basic_text_oprimitive.hpp (54) : warning C4103: 'c:\work\stl\boost\boost_1_34_1\boost\archive\basic_text_oprimitive.hpp' : alignment changed after including header, may be due to missing #pragma pack(pop) ... 1>C:\WORK\STL\boost\boost_1_34_1\boost/serialization/collections_save_im p.hpp(38) : warning C4267: 'initializing' : conversion from 'size_t' to 'unsigned int', possible loss of data 1> C:\WORK\STL\boost\boost_1_34_1\boost/serialization/list.hpp(39) : see reference to function template instantiation 'void boost::serialization::stl::save_collection<Archive,std::list<_Ty>>(Archi ve &,const Container &)' being compiled 1> with 1> [ 1> Archive=boost::archive::xml_oarchive, 1> _Ty=std::pair<bus_schedule::trip_info,bus_route *>, 1> Container=std::list<std::pair<bus_schedule::trip_info,bus_route *>> 1> ] 1> C:\WORK\STL\boost\boost_1_34_1\boost/serialization/split_free.hpp(45) : see reference to function template instantiation 'void boost::serialization::save<Archive,std::pair<_Ty1,_Ty2>,std::allocator<_ Ty>>(Archive &,const std::list<_Ty> &,const unsigned int)' being compiled 1> with 1> [ 1> Archive=boost::archive::xml_oarchive, 1> _Ty1=bus_schedule::trip_info, 1> _Ty2=bus_route *, 1> _Ty=std::pair<bus_schedule::trip_info,bus_route *> 1> ] ... 1>Linking... 1> Creating library C:\WORK\STL\TST\ExampleXmlSave\x64\Release\ExampleXmlSave.lib and object C:\WORK\STL\TST\ExampleXmlSave\x64\Release\ExampleXmlSave.exp 1>Generating code 1>Finished generating code 1>Embedding manifest... 1>Build log was saved at "file://c:\WORK\STL\TST\ExampleXmlSave\ExampleXmlSave\x64\Release\BuildL og.htm" 1>ExampleXmlSave - 0 error(s), 68 warning(s) ========== Rebuild All: 1 succeeded, 0 failed, 0 skipped ==========

boost::test run by name
by Tim St. Clair 23 Oct '07

When is the tentative plan to support "run-by-name" Also, are there plans to support test suite registration which is not run unless explicitly specified? (e.g. - hardware required to perform the test) Thanks for your help, Tim

numerics question...
by Graham Reitz 22 Oct '07

How do you round (i.e. from a float to int) with boost::numerics? It seems like there should be a fairly straightforward method (been poking around the documentation). Thanks, Graham
