Boost 1.32 + VC8 + serialization compilation error
by Pramod Sharma 12 May '08

12 May '08

Hi, I am trying to compile boost 1.32 with Visual Studio 2005 and serialization library is not getting compiled because of compilation issues. I tried to search it at lot of places with no luck. Can anyone please help me on this ? I am attaching my logfile with this.

Exposing C++ Functions with Container Arguments in Boost.Python
by Bilokon, Paul 11 May '08

11 May '08

[This question is about Boost.Python. If there is a more approprate mailing list to send it to, please do let me know.] Hi all, This is probably a trivial question, but after some research I was unable to find a "best practice" answer, so my sincere apologies. I am trying to expose a C++ function which takes an std::vector<double> as its argument, some void A::foo(std::vector<double> v); And perhaps void A::bar(std::vector<double> & v); Whether it is a good practice to have such arguments is, of course, open to debate (shouldn't they be iterators?), but this is what I have to work with. The question remains, what is the best way to expose these to python? I cannot pass a Python list -- it's a type mismatch. Many thanks!

read/write lock for concurrent access
by Selçuk Giray Özdamar 11 May '08

11 May '08

Hi everyone, Does boost supports for CREW(concurrent read/exclusive write) model for preventing race conditions? Also in another words does it support read/write lock ?

[bgl] graphML support and non PIC expat library
by come raczy 11 May '08

11 May '08

Hello, Is there any way to build the bgl with graphml support, using an expat static lib which has been compiled without the '--with-pic' configure option? I am asking because the expat static library provided by ubuntu 8.04 is compiled for non PIC object. Therefore, I was wondering if there were better solutions than either recompiling expat or linking the bgl to the shared expat library. Cheers Come

Asio & inter-thread events
by TD 11 May '08

11 May '08

Hello, I encounter many scenarios where a thread needs to sleep on both an IO event and a logical event. Here's a common case. Thread A is an IO thread. It gets data from a socket, puts it in a buffer pool, and notifies thread B. Thread B is a worker thread. It calculates stuff, then returns buffers to the pool. It follows then that thread A sometimes sleeps on IO (when waiting for socket data), and sometimes sleeps waiting for the pool to become non-empty. It would be nice if there were a uniform way for the thread to sleep on stuff. For example, using Windows API, a completion port can be used to sleep on both a socket and an event object. In UNIX, thread A could select both a socket (for data) and a pipe. I don't, however, understand how to do so cleanly using asio. Anything that I can think up doubles up the size/complexity of the code, and seems to use more system calls. I'd appreciate any suggestions. Thanks, TD

using std::wstring in serialization
by Dennis Yurichev 10 May '08

Hello, I'm looking on possibility to use std::wstring in serialization. Here is a simple example which I try to compile: #define UNICODE #include <windows.h> #include <assert.h> #include <stdio.h> #include <string> #include <map> #include <iostream> #include <fstream> #include <boost/config.hpp> #include <boost/archive/binary_oarchive.hpp> #include <boost/archive/binary_iarchive.hpp> #include <boost/serialization/map.hpp> #include <boost/serialization/string.hpp> int main() { std::map<std::wstring, std::wstring> t; std::ofstream ofs ("test.dat", std::ios::trunc | std::ios::binary ); boost::archive::binary_oarchive oa(ofs); assert (ofs.good()); t[L"asd"]=L"test"; oa << t; ofs.close(); }; I use latest downloaded boost and mingw 3.4.5. I got such error: c:/boost/boost/serialization/access.hpp: In static member function `static voidboost::serialization::access::serialize(Archive&, T&, unsigned int) [with Archive = boost::archive::binary_oarchive, T = std::basic_string<wchar_t, std::char_tr aits<wchar_t>, std::allocator<wchar_t> >]': c:/boost/boost/serialization/serialization.hpp:81: instantiated from `void boost::serialization::serialize(Archive&, T&, unsigned int) [with Archive = boost::archive::binary_oarchive, T = std::basic_string<wchar_t, std::char_traits<wchar_ t>, std::allocator<wchar_t> >]' c:/boost/boost/serialization/serialization.hpp:140: instantiated from `void boost::serialization::serialize_adl(Archive&, T&, unsigned int) [with Archive = boost::archive::binary_oarchive, T = std::basic_string<wchar_t, std::char_traits<w char_t>, std::allocator<wchar_t> >]' c:/boost/boost/archive/detail/oserializer.hpp:151: instantiated from `void boost::archive::detail::oserializer<Archive, T>::save_object_data(boost::archive::detail::basic_oarchive&, const void*) const [with Archive = boost::archive::binar y_oarchive, T = std::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> >]' test.cpp:96: instantiated from here c:/boost/boost/serialization/access.hpp:109: error: 'struct std::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> >' has no member named 'serialize' So, what the right way to use wstring here? -- My PGP public key: http://yurichev.com/dennis.yurichev.asc

Boost Bimap Question
by Surya Kiran Gullapalli 10 May '08

10 May '08

Hello, I've started using boost bimap recently and i encountered a problem. With the standard c++ containers, I can always use forward declaration of my classes in the interface files (header files) and then include the appropriate header files in the implementation files (source files). With boost bimap this seems to be not possible. Lets say I've MyClass and I do like this. ---------------------------- class MyClass boost::bimap<string, MyClass> my_bimap ; -------------------------- The compiler spits out a lot of error messages. But If i avoid forward declaration and include MyClass header file before declaring boost::bimap, every thing is normal. Is there any way I can avoid this header file inclusion just use forward declaration ? Thanks in advance, Surya

Is there an easy way to test two multi_index containers for equality, c1 == c2?

ok, i use a this instead of a shared_from_this(). Now it works. I still need an answer for question 1 though...

Ok, I know where the server crashes now. int SSL_accept(SSL *s) { if (s->handshake_func == 0) /* Not properly initialized yet */ SSL_set_accept_state(s); return(s->method->ssl_accept(s)); } the application cannot access ssl_accept. Apparently s->method is "invalid".
