[Serialization] Polymorphic portable binary archive error
by Szymon Gatner 04 Apr '14

04 Apr '14

Hi, I am trying to use polymorphic_portable_binary_archive in Visual Studio 2012 but adding relevant *.cpp(s) (from examples directory) to the project yields: 1>c:\users\bravo\documents\visual studio 2012\projects\polymorphic_serialization_test\polymorphic_portable_binary_oarchive.hpp(19): fatal error C1083: Cannot open include file: 'boost/archive/detail/polymorphic_oarchive_dispatch.hpp': No such file or directory 1>c:\users\bravo\documents\visual studio 2012\projects\polymorphic_serialization_test\polymorphic_portable_binary_oarchive.cpp(18): fatal error C1083: Cannot open include file: 'boost/archive/impl/archive_pointer_oserializer.ipp': No such file or directory Error 2 error C1083: Cannot open include file: 'boost/archive/detail/polymorphic_iarchive_dispatch.hpp': No such file or directory c:\users\bravo\documents\visual studio 2012\projects\polymorphic_serialization_test\polymorphic_portable_binary_iarchive.hpp 19 polymorphic_serialization_test Indeed, none of those files exists in my boost release, I am using boot 1.54. Also: what is the status of Portable Binary Archives? From forum posts It would seem that ony unsupported things is floating point numbers? Is that correct? Other that that, is everything else production ready? Regards, Szymon Gatner -- Szymon Gatner Bravasoft / The Lordz Games Studio Twitter: @sgatner

boost::regex_replace problem
by Илья 04 Apr '14

04 Apr '14

Greetings everyone! My name is Ilya and i have such problem with boost::regex_replace : I want to process some text messages to find and replace with * swears there. I wrote regular expressions, this is an example of one of them: "([[:punct:]]|[[:space:]]|[[:digit:]]|^)(?:a)(?:[[:punct:]]|[[:space:]]|[[:digit:]])*(?:b)(?:[[:punct:]]|[[:space:]]|[[:digit:]])*(?:c)([[:punct:]]|[[:space:]]|[[:digit:]]|$)". The format string i used is: "$1***$2" Then i run boost::regex_replace() and it works almoust correctly, except one case: when i have message with abc's standing next to each other with one separator beetween them, like this: "abc abc", "--abc-abc--" etc. So i need to run boost::regex_replace() twice to process corectly such messages. Are there any other ways to solve this problem? Thank you for answers. Ilya Bindiug

[Serialization] good practice for serialization with private default constructors
by David Rajaratnam 04 Apr '14

04 Apr '14

I am interested to know what is good practice when dealing with serializable classes with private default constructors. In particular it is not clear what is the cleanest way to deserializing these objects. Explaining with reference to the example from: http://stackoverflow.com/questions/7123613/boost-serialization-does-the-def… The answer to this stackoverflow question shows how to serialize/deserialize an object with a private default constructor. Summarizing: class Colour { friend class boost::serialization::access; // private default constructor // template serialize function public: boost::shared_ptr<Colour> test() { // returns new object; } }; int main(){ boost::shared_ptr<Colour> c = Colour::test(); std::stringstream str; boost::archive::text_oarchive oa(str); oa & c; // ... c.reset(); boost::archive::text_iarchive ia(str); ia & c; } However, it is important to observe that it is not just serializing/deserializing the object itself but also the shared pointer to the object! So for example: replacing "ao & c;" with "oa & *c;" will compile and properly serialize (only) the object, but will throw an exception when it tries to deserialize because it is expecting a shared pointer to the object. My solution to this is to provide a constructor that takes an archive object: class Colour { // other stuff public: template<typename Archive> Colour(Archive& ar) { ar >> *this; } }; // some explicit specializations where there are // other single argument constructors The example main then becomes: int main(){ boost::shared_ptr<Colour> c = Colour::test(); std::stringstream str; boost::archive::text_oarchive oa(str); oa & *c; // ... boost::archive::text_iarchive ia(str); Colour c2(ia); } The above works and is clean in that only the Colour object is being serialized/deserialized. However, I'm not sure if it is good practice. In particular: - I presume there will be an intermediate copy of the Colour object being created by the archive object. - Passing *this to a function that takes an object of type Object from within the constructor seems like a bad thing. - In general template based constructors seems like they should be avoided. So, my question is whether my solution is reasonable or is there a better option. Regards, Dave R.

[wave] fail to parse variadics macro
by gag maker 03 Apr '14

03 Apr '14

Hi, I'm using wave library from boost 1.53.0. Library compiled with default settings, meaning BOOST_WAVE_SUPPORT_VARIADICS_PLACEMARKERS is set to 1 in wave_config.cpp Wave driver is also compiled to support variadics. However, when I try to feed translation unit to wave driver it reports following error: .../compiler.h:32:1: error: ill formed preprocessor directive: #define __builtin_warning(x, y...) (1) And btw, wave driver was called with --variadics option What went wrong here? Thank you, --Alex

problems with nested boost::bind and boost::asio
by Marco 03 Apr '14

03 Apr '14

Hi, I use async_read of boost::asio to receive network data. After a complete 'packet' was read (which needs 2 async read calls) I want to call a user defined handler. Therefore, I introduced a new templater parameter in my callback methods. Unfortunately, my code ends in a compile error. If I outcomment the handler call, than it compiles fine. But with the call of the handler object, I got a conversion error. At first I want to describe my code on some excerpts: ---------------------------------------------------------------------------------------- In 'startProcessing' I use perfect forwarding for the callback object. template<typename T> void startProcessing(T&& handler,bool activateNoDelay = true) { // m_socket.set_option(asio::ip::tcp::no_delay(activateNoDelay )); // startAsyncRead(std::forward<T>(handler)); } ---------------------------------------------------------------------------------------- 'startAsynRead' has two overloads. One for boost::bind objects and one for all other. The boost bind objects are encased with boost::protect to prevent an evaluation of boost::bind in the later binds. // template<typename T> void startAsyncRead(T handler) { startAsyncReadImpl(handler); } //overload for boost bind objects necessary template<typename R, typename F, typename L> void startAsyncRead(boost::_bi::bind_t<R, F, L> handler) { startAsyncReadImpl(boost::protect(handler)); } ---------------------------------------------------------------------------------------- 'startAsyncReadImpl' calls asio::async_read and uses boost::bind to commit the handler object as a third parameter. // template<typename T> void startAsyncReadImpl(T&& handler) { //at first we need to read the header information auto& buf = m_headerInBuffer.getBuffer(); boost::asio::async_read( m_socket, boost::asio::buffer(buf.begin(), buf.size()), boost::asio::transfer_exactly(buf.size()), boost::bind(&CMessageChannel::handleAsyncReadHeader<T>, this,_1, _2, std::forward<T>(handler)) ); } ---------------------------------------------------------------------------------------- 'handleAsyncReadHeader' does some stuff and than calls asio::async_read with another method. // template<typename T> void handleAsyncReadHeader(const boost::system::error_code& error, std::size_t bytes_transferred, T handler) { . . . boost::asio::async_read( m_socket, boost::asio::buffer(buf.begin(), buf.size()), boost::asio::transfer_exactly(size), boost::bind(&CMessageChannel::handleAsyncReadBody<T>, this, _1, _2,handler) ); } ---------------------------------------------------------------------------------------- Finally, 'handleAsyncReadBody' has to do the wished call of the handler. // template<typename T> inline void CMessageChannel::handleAsyncReadBody(const boost::system::error_code& error, std::size_t bytes_transferred, T handler) { ... handler(Packet(m_headerInBuffer.getShort(4), bytes_transferred, m_currReadBuffer)); } ---------------------------------------------------------------------------------------- And here a call of start process: void testPacket(Packet& packet) {} . . . conn->startProcessing(boost::bind(&CMessageServer::testPacket, this, _1)); ---------------------------------------------------------------------------------------- I use Visual Studio 2013 and got the following error message: 1>D:\libraries\cpp\boost\boost_1_55_0\boost/bind/bind.hpp(313): error C2664: 'void boost::_mfi::mf1<void,tuc::nw::CMessageServer,tuc::nw::Packet &>::operator ()(T *,A1) const' : Konvertierung von Argument 2 von 'const tuc::nw::Packet' in 'tuc::nw::Packet &' nicht möglich -> can't convert argument 2 'const tuc::nw::Packet' to tuc::nw::Packet & I never use const in my call chain.

installing boost getting error "ld: symbol(s) not found for architecture x86_64" on OSX 10.9.2
by Corentin Hamel 02 Apr '14

02 Apr '14

Hi everyone, I hope this is the right place to ask my question. I'm trying to build boost 1.55.0 for python on OSX 10.9.2 but i'm encountering the following error "ld: symbol(s) not found for architecture x86_64" and I'm really blocked. I read it might be related to the standard c++ library which changed with maverick to be libc++ by default. But even adding cxxflags="-stdlib=libstdc++" when executing ./b2 didn't help. Here is what I did following the boost tutorial: download boost_1_55_0.tar ./bootstrap.sh --with-libraries=python toolset=darwin ./b2 include="/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7/" And I get the following error: link.jam: No such file or directory Building the Boost C++ Libraries. error: No best alternative for /python_for_extensions next alternative: required properties: <python>2.7 <target-os>darwin matched next alternative: required properties: <python>2.7 <target-os>darwin matched error: No best alternative for /python_for_extensions next alternative: required properties: <python>2.7 <target-os>darwin matched next alternative: required properties: <python>2.7 <target-os>darwin matched Component configuration: - python : building darwin.link.dll bin.v2/libs/python/build/darwin-4.2.1/release/threading- multi/libboost_python.dylib Undefined symbols for architecture x86_64: "_PyFile_FromString", referenced from: boost::python::exec_file(boost::python::str, boost::python::api::object, boost::python::api::object) in exec.o "_PyFile_AsFile", referenced from: boost::python::exec_file(boost::python::str, boost::python::api::object, boost::python::api::object) in exec.o "_PyEval_GetGlobals", referenced from: boost::python::eval(boost::python::str, boost::python::api::object, boost::python::api::object) in exec.o boost::python::exec(boost::python::str, boost::python::api::object, boost::python::api::object) in exec.o boost::python::exec_statement(boost::python::str, boost::python::api::object, boost::python::api::object) in exec.o boost::python::exec_file(boost::python::str, boost::python::api::object, boost::python::api::object) in exec.o "_PyRun_StringFlags", referenced from: ........
