Hello Rush and everybody, Thank you for your answer. Unfortunately, it does NOT match the name. The name computed "by auto_link.hpp" is boost_filesystem-vc71-mt-s-1_33.lib and the name of the static library on my computer is boost_filesystem-vc71-mt-1_33.lib (without the '-s'). So my problem is a problem of name mismatch, not a problem of project configuration for linking. Thank you.

This should be settable via the linker preferences, but I use VS 2005, so don't know how you would do it. - Rush _______________________________________________ Boost-users mailing list Boost-users(a)lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users

Is the class unit_test_result deprecated? I have boost 1.33.1 installed and it is not a part of the installation. Is there something else I am suppose to be using? Stephen

[regex] boost, problem compiling doc example of boost::match_extra

I am trying to use the repeat capture mechanism in regex i thought i would start with the documentation example, but im having problems compiling it. Any help is appreciated.

[lambda] if-then-else construct gets broken by lambda-lib
by Sebastian Weber 08 Nov '06

08 Nov '06

Hello everybody! I'm trying to store a reference to a function depending upon a condition within a function object like this: boost::function< double (std::size_t) > wf = (sIndex < m_maxIndex+1) ? ( boost::lambda::bind(boost::ref(m_cf), sDeg, boost::lambda::_1) ) : ( boost::ref(*m_wf) ); However, this does not compile. The error message is: error: no match for ternary 'operator?:' in '(sIndex < (((boost::cor_cm_iterator4<RandomGenerator, Graph>*)this)->boost::cor_cm_iterator4<RandomGenerator, Graph>::m_maxIndex + 1)) ? boost::lambda::bind(boost::ref(((boost::cor_cm_iterator4<RandomGenerator, Graph>*)this)->boost::cor_cm_iterator4<RandomGenerator, Graph>::m_cf), sDeg, boost::lambda::<unnamed>::_1) : boost::ref((*((boost::cor_cm_iterator4<RandomGenerator, Graph>*)this)->boost::cor_cm_iterator4<RandomGenerator, Graph>::m_wf))' But the lengthy code boost::function< double (std::size_t) > wf; if(sIndex < m_maxIndex+1) wf = boost::lambda::bind(boost::ref(m_cf), sDeg, boost::lambda::_1); else wf = boost::ref(*m_wf); compiles fine. Any idea? How can lambda eat up the ? : construct? How do I prevent that? My system is a ubunut edgy which means, I have g++ 4.1 and use boost 1.33.1. Greetings, Sebastian Weber

Socket and iostream
by Ivan LAURETTE 08 Nov '06

08 Nov '06

Darwin 8.8.0 Boost 1.33.1 gcc 4.0.1 Hello, I want to establish a SMTP connection through a socket, then dialog with the server using a stream. I thought I could to it like this: //-------------------------------------------- #include <boost/iostreams/stream.hpp> #include <boost/iostreams/device/file_descriptor.hpp> using namespace std; using namespace boost::iostreams; ... int theSocket = socket(AF_INET,SOCK_STREAM,0); connect(theSocket, ...); file_descriptor fdDevice(theSocket); stream_buffer<file_descriptor> fdstream(fdDevice); iostream os(&fdstream); string answer; getline(os, answer); cout << answer << endl; os << "HELO xxxxx" << endl; getline(os, answer); cout << answer << endl; os << "MAIL FROM: <xxx.xxx(a)xxx.xxx>" << endl; getline(os, answer); cout << answer << endl; ... //-------------------------------------------- But nothing seems to be written nor readen to/from the socket except for the first getline. What am I doing wrong here ? Thanks in advance for any help.

[asio] Breaking changes committed to cvs HEAD
by Christopher Kohlhoff 08 Nov '06

08 Nov '06

I have just committed some asio changes to cvs HEAD that will break application code. These changes are part of what's needed to bring the interface into sync with the TR2 proposal. The big change is to the error handling classes, as described below. An async handler of the form: void my_handler(const boost::asio::error& e); becomes: void my_handler(const boost::system::error_code& e); Synchronous error handling like this: boost::asio::error e; sock.connect(ep, boost::asio::assign_error(e)); becomes: boost::system::error_code e; sock.connect(ep, e); And where previously a boost::asio::error exception was thrown, the new exception thrown is boost::system::system_error. Error constants like boost::asio::error::eof stay as they are, i.e.: void my_handler(const boost::system::error_code& e) { if (e == boost::asio::error::eof) { ... } } Programs will now need to link against the boost.system library (which is where boost::system::error_code and boost::system::system_error reside). Once I do a few more TR2-related changes I will post regenerated doxygen documentation to the vault. Stay tuned. Cheers, Chris

[Threads]Exception-safety of thread_group::add_thread
by Ai Azuma 08 Nov '06

08 Nov '06

Hi, I have questions about `boost::thread_group::add_thread' member function. The documents don't seem to say anything about exception-safety of this function. Therefore, I have questions; 1. Is this no-throw? 2. If the answer to 1. is "no", then how does it treat the ownership of its argument when an exception is thrown? Could anyone help me? Thanks in advance. -- Ai Azuma <ai.azuma(a)gmail.com>

[Boost.Filesystem] problem to link an executable to boost_filesys tem static library on Windows XP
by Johan.GUIHENEUF＠external.thalesgroup.com 07 Nov '06

07 Nov '06

Hello, I try to build an console executable that uses boost_fileystem library. I have got the file boost_filesystem-vc71-mt-1_33.lib. My IDE is Visual C++ 7.1. I set the preprocessor definition _MT. At build step, I have this error: "could not find boost_filesystem-vc71-mt-s-1_33.lib". I had a look to boost/config/auto_link.hpp to see what "#define" I forgot but I do not understand why it chooses "#define BOOST_LIB_RT_OPT -s". hat preprocessor macro should I define to make it choose "#define BOOST_LIB_RT_OPT" (i.e. empty) ? Is there a blocking problem with Visual C++ 7.1 on Windows XP ? Thank you. Johan GUIHENEUF
