The version you created goes below this bottom of the first +, which as you said makes it less compact. Take that bottom C part and puch it up one "block", making sure you keep the + sign on top of the background. In essence, you'd really just be adding a single block of background in the lower left gap of the first +, and another block to the lower right gap of the first +, if that makes any sense. - Robert Geiman

boost.thread : Can one create a thread with an object member function?
by Tim Laplaca 22 Nov '04

22 Nov '04

I am very new to boost, I apologize if this has been asked before. I searched the mailing list archive but could not find an answer to my question. I was successful creating threads with functions that are not members of objects, but when I try to create threads with a pointer to an object member I get compilation errors (MS Visual Studio .NET). Examples: class objclass; typedef void (objclass::*pmf)(); // ptr to member func class objclass { public: objclass() : thread_id (0) { p=&objclass::dowork; } inline setthreadid(int x) {thread_id = x;} inline setvaltwo(std::string str) {valtwo = str;} void dowork(); pmf p; // pointer to dowork member function int getthreadid() {return thread_id;} std::string getvaltwo() {return valtwo;} private: int thread_id; std::string valtwo; }; void objclass::dowork() { } (In the main...) boost::thread_group thrds; objclass * objthread; objthread = new objclass; thrds.create_thread( (objthread->p) ); I get the following error: c:\Boost\include\boost-1_31\boost\function\function_template.hpp(427): error C2664: 'void boost::function0<R>::assign_to<Functor>(FunctionPtr,boost::detail::funct ion::function_ptr_tag)' : cannot convert parameter 2 from 'boost::detail::function::member_ptr_tag' to 'boost::detail::function::function_ptr_tag' with [ R=void, Functor=pmf, FunctionPtr=pmf ] Is there a way around this problem, or is it simply not possible to make threads from object members with boost? Thanks, Tim

Yes, I like the simplicity a lot. However, I'd also make a slight change to the background of the ++. Could you remove the lower right background of the ++, and instead mirror the upper left background vertically. That is, the background would appear in the upper and lower left area of the ++. To me this would look better as the background would look like the letter C, which would go nicely with the ++. - Robert Geiman

[serialization] std::set compile errors
by Jeff Flinn 22 Nov '04

22 Nov '04

Robert, boost 1.32, with VC7.1 I'm getting compiler errors in two unrelated translation units both dealing with std::set<std::string> data members. I've gone through and ensured that i've #include'd the <set.hpp> and <string.hpp> headers from boost/serialization. Any ideas on what might be causing this problem? This has worked fine previously with boost 1.31 and serialization20 version of the library. Why would the 3 argument overload not be found? Below are the (beginnings of the ) related compiler errors. Thanks, Jeff ======================== C:\boost\boost_1_32_0\boost\serialization\split_free.hpp(55) : error C2780: 'void boost::archive::load(Archive &,T &)' : expects 2 arguments - 3 provided C:\boost\boost_1_32_0\boost\archive\detail\iserializer.hpp(514) : see declaration of 'boost::archive::load' C:\boost\boost_1_32_0\boost\serialization\split_free.hpp(54) : while compiling class-template member function 'void boost::serialization::free_loader<Archive,T>::invoke(Archive &,T &,const unsigned int)' with [ Archive=boost::archive::text_iarchive, T=std::set<std::string> ] .... ======================== C:\boost\boost_1_32_0\boost\serialization\split_free.hpp(55) : error C2780: 'void boost::archive::load(Archive &,T &)' : expects 2 arguments - 3 provided C:\boost\boost_1_32_0\boost\archive\detail\iserializer.hpp(514) : see declaration of 'boost::archive::load' C:\boost\boost_1_32_0\boost\serialization\split_free.hpp(54) : while compiling class-template member function 'void boost::serialization::free_loader<Archive,T>::invoke(Archive &,T &,const unsigned int)' with [ Archive=boost::archive::binary_iarchive, T=std::set<std::string> ] ....

[serialization] and macro 'max' compiler warning on VC71
by Jeff Flinn 22 Nov '04

22 Nov '04

I've just tried to move to 1.32 and get the following warning: C:\boost\boost_1_32_0\boost\archive\basic_binary_oprimitive.hpp(101) : warning C4003: not enough actual parameters for macro 'max' which points to: assert( static_cast<std::size_t>(std::numeric_limits<std::streamsize>::max()) >= count ); Any suggestions on avoiding this with an MFC based project? Thanks, Jeff

Under the Reference section, the sentence: Originally const references was used, but it lead to many problems with string-literals. Should read: Originally const references were used, but it led to many problems with string-literals.
