[asio].[solaris].[1_33_1] problem in compiling test case
by Gaurav.Jain＠iflexsolutions.com 15 Feb '07

Hi, I have tried using boost 1_33_1 on Solaris machine, while compiling the program I am getting some errors. Can anybody help me out? The detail of the compilation is as follows: Boost Version: 1_33_1 Compiler Details: Sun Studio 11: C++ 5.8 Compiler OS Details: SunOS FICTESTING 5.10 Generic_118833-03 sun4u sparc SUNW,Sun-Fire-280R While compiling "buffered_read_stream.cpp" I am getting the following : $CC -I$HOME/1.33.1/64/include/ -D_XOPEN_SOURCE=500 -D__EXTENSIONS__ -library=stlport4 -features=tmplife -features=tmplrefstatic buffered_ read_stream.cpp -lnsl -lsocket -lxnet Undefined first referenced symbol in file std::string boost::system::error_code::message()const buffered_read_stream.o boost::system::error_category boost::system::error_code::new_category(int(*)(const boo st::system::error_code&),std::string (*)(const boost::system::error_code&),std::wstrin g (*)(const boost::system::error_code&)) buffered_read_stream.o ld: fatal: Symbol referencing errors.

Hello everyone again: I'm resending this because the first URL was not correct. The other URLs were correct, so to sum up:: The library can be downloaded from Boost.Vault/Containers: URL: http://www.boost-consulting.com/vault/index.php?directory=Containers Tiny URL: http://tinyurl.com/ysfclr Online documentation and the documentation package can be found here: http://tinyurl.com/y95qng Sorry for the noise, Ion

[multi_index] SIGABRT in multi_index_container constructor
by Manuel Jung 15 Feb '07

15 Feb '07

Hi, Im defining a class with a multi_index_container as base. When i construct a instance of this class, and the multi_index_container is called, the program crashes. It even crashes, when i dont use it as a base class. Like this: struct query { query(unsigned int id_, unsigned short pr_, unsigned short type_, unsigned short status_); virtual ~query(); enum estatus{WAITING=0, WORKING=1, BUFFERED=2}; unsigned int id; unsigned short pr; unsigned short type; unsigned short status; typedef boost::shared_ptr<query> pointer; }; struct query_rank_key:composite_key< query::pointer, member<query,unsigned short,&query::status>, member<query,unsigned short,&query::pr>, member<query,unsigned int,&query::id> >{}; typedef multi_index_container< query::pointer, indexed_by< ordered_non_unique< query_rank_key #if defined(BOOST_NO_TEMPLATE_PARTIAL_SPECIALIZATION) ,composite_key_result_less<query_rank_key::result_type> #endif >, ordered_unique< tag<tid>,member<query,unsigned int,&query::id> > > queue_set; class queue : public queue_set { public: queue(){}; virtual ~queue(){}; typedef boost::shared_ptr<queue> pointer; }; This compiles just fine, but if i run the code i get the following backtrace after a Sigmentation Abort. It happens, when the queue::queue() is called. Someone a idee whats it about? Im new to boost::multi_index, so maybe i misunderstud something?

Boost::shared_ptr from void
by Dave Nay 15 Feb '07

15 Feb '07

Hi All! I am using a third party library where I enqueue a series of events. Each of these events allows the passing of a user context void*. I am attempting to pass the address of a boost::shared_ptr as my context. typedef boost::shared_ptr<CBuffer> CBufferPtr; for (i = 0; i < PREQUEUESIZE; i++) { handle = RegisterBuffer(buffer->m_pBCAMBuffer, m_AOISize); QueueBuffer( handle, &buffer ); // The second parameter is a void* user context data } In the above code "buffer" is my shared_ptr. Later, in my event handler I have the following: CBufferPtr buffer = static_cast<CBufferPtr>(result.Context()); This does not compile due to the following error in VS2005: 1>c:\boost\include\boost-1_33_1\boost\shared_ptr.hpp(125) : error C2440: 'initializing' : cannot convert from 'const void *' to 'CBuffer *' 1> Conversion from 'void*' to pointer to non-'void' requires an explicit cast 1> d:\sourcecode\test.cpp(1572) : see reference to function template instantiation 'boost::shared_ptr<T>::shared_ptr<const void>(Y *)' being compiled 1> with 1> [ 1> T=CBuffer, 1> Y=const void 1> ] The problem seems to be that the third party library call to result.Context() is returing a const void*. It also seems to me that my handler code is actually executing the overloaded operator=, and can never actually cast from a void* to a shared_ptr<T>. What can I do to successfully cast a void* to a shared_ptr<T>? Thanks, Dave

[multi_index] derived class from multi_index_container?

Hi, Can u define a class with a multi_index type as base? Like this: struct query { query(unsigned int id_, unsigned short pr_, unsigned short type_, unsigned short status_); virtual ~query(); enum estatus{WAITING=0, WORKING=1, BUFFERED=2}; unsigned int id; unsigned short pr; unsigned short type; unsigned short status; typedef boost::shared_ptr<query> pointer; }; struct query_rank_key:composite_key< query::pointer, member<query,unsigned short,&query::status>, member<query,unsigned short,&query::pr>, member<query,unsigned int,&query::id> >{}; typedef multi_index_container< query::pointer, indexed_by< ordered_non_unique< query_rank_key #if defined(BOOST_NO_TEMPLATE_PARTIAL_SPECIALIZATION) ,composite_key_result_less<query_rank_key::result_type> #endif >, ordered_unique< tag<tid>,member<query,unsigned int,&query::id> > > > queue_set; class queue : public queue_set { public: queue(){}; virtual ~queue(){}; typedef boost::shared_ptr<queue> pointer; }; This compiles just fine, but if i run the code i get the following backtrace after a Sigmentation Abort. It happens, when the queue::queue() is called. Someone a idee whats it about? Or cant i derive a class from a multi_index_container? I didnt found something about it in the docs or mailing list.

[asio] Using tcp::iostreams with Boost.Iostreams filtered_streambuf
by Darren Garvey 14 Feb '07

14 Feb '07

Hi, I was wondering about tcp::iostreams. I need to have the ability to write code like: obj<< "Hello world" and at intervals (of size) have a header attached and then have it written to an open socket. I have been looking into Boost.Iostreams to do this, but I was wondering if rather than implementing the whole streambuf/sink, I could just create a filtering_streambuf (naming convention taken from Boost.Iostreams) - which would attach the header when needed - and just instantiate a tcp::iostream object with that streambuf. I'm still very foggy on the Iostreams library - and streams/buffers in general - but does that sound like it could work? Sorry about the vagueness, Darren

[signals] rationale for signals::connection::disconnect() const
by Frank Mori Hess 14 Feb '07

14 Feb '07

I just noticed that boost.signals declares signals::connection::disconnect() as a const member function. Can anyone explain to me why that was done? It seems like a non-const operation to me. That's how I declared it in thread_safe_signals, and it doesn't seem to cause any problems there. -- Frank

How to block a signal
by Dahman 14 Feb '07

14 Feb '07

Hi, I have a signal with many slots connected to it and I have a class object witch want to have the possibility to block this signal at the start and unblock it later, but know nothing about what and how many slots are connected to it (then can't use connection.disconnect()). Is there any solution for this problem? Thanks for any help.

program_options boost::bad_any_cast: failed conversion using boost::any_cast
by Raiko Albrecht 14 Feb '07

14 Feb '07

Hi, since a while I always get this any-cast error when using program_options with type "std::string". to check it out I'd modified the simple example from boost for program_options a little bit (checking if any_type as it works - does, inserted a string-parameter). Compiling, starting with "--log astring" -> crash. starting without works at expected. (See appended source file) System is Debian etch, X86_64, gcc 4.1.2 20061115 boost: tried with debian package and self build variant. question now is: why? what may I do? As far as I remember on a unstable 32bit with gcc 4.0 it did work, but not sure if I got it running on a 64 bit system later. Hope for help Rajko

using unit_test_log
by Paez, Juan 14 Feb '07

14 Feb '07

Hello, I new using boost. I am trying to setup a set of test cases to test some api. I would like to be able to use the logging facilities that boost provides through the unit_test_log class. I understand that from the command line you can set the logging parameters. However, I want to be able to set those parameters from inside the my program executing the test cases. any ideas? Specifically, I want to be able to send the log output to specific files (the files change depending on the test suite I am running), the format, level, etc. Thanks, Juan
