[utility] declval addition? [type_traits] add_rvalue_reference addition?
by vicente.botet 14 Aug '10

14 Aug '10

Hi, I was wondering if we can add the declval utility function template to the Boost.Utility library 20.3.4 Function template declval [declval] 1 The library provides the function template declval to simplify the definition of expressions which occur as unevaluated operands (Clause 5). template <class T> typename add_rvalue_reference<T>::type declval() noexcept; // as unevaluated operand 2 Remarks: If this function is used (as defined by (3.2)), the program is ill-formed. 3 Remarks: The template parameter T of declval may be an incomplete type. [ Example: template <class To, class From> decltype(static_cast<To>(declval<From>())) convert(From&&); declares a function template convert which only participats in overloading if the type From can be explicitly converted to type To. For another example see class template common_type (20.7.6.6). -end example ] BTW, add_rvalue_reference is not available on Boost.TypeTraits, add_rvalue_reference_layer. Any problem to add it? Best, _____________________ Vicente Juan Botet Escribá http://viboes.blogspot.com/

[shared_ptr] Detect shared_ptr argument at compile time
by Ralf Globisch 13 Aug '10

13 Aug '10

Hi, I'm not sure if this is the correct mailing list for this question: Is there a way to determine if a template parameters is of type boost::shared_ptr at compile time? I would like to do something like: template<class A> void doSomething( const A& a) { // if "a" is of type boost::shared_ptr<SomeType> a->someMethod(); // else a.someMethod(); } Is this possible at all? Regards, Ralf

Oh, I see. My problem was actually not specifing -lboost_program_options on the command line which gave linker error. I'm using cmake now, and it seems that program_options get statically linked. How can I get it to dynamic link instead? I know this is more of a cmake question, so sorry. Thanks, Petr

How can I give the load/save functions friend access to my class? I'm using Visual Studio 2008 with Boost Version 1.42.0. Thanks, Glen

Any interest in creating new CORBA IDL to C++ mapping?
by Johnny Willemsen 10 Aug '10

10 Aug '10

Hi all, We are talking with various users of TAO to see if we can create a new modern IDL to C++ mapping. The idea is to drop all old compilers which lead to the current mapping and make a new IDL to C++ mapping that is using the latest draft C++0x standard. We want to use full STL, shared_ptr, r-value, and everything else we could need. The idea is to prototype this first in TAO and than see if on the long term we can propose a new IDL to C++ V2 mapping to the OMG I did find some discussions on this list about 2 years ago, are people interested in this effort, any input is welcome.

[chrono] Compatibility issues with 1.44
by Roland Bock 10 Aug '10

10 Aug '10

Hi Vicente, do you have an estimate for an update of Boost.Chrono which is compatible with the upcoming 1.44 version of boost? I just tried the daily snapshot provided by Beman with the current Chrono zip: * Compilation of Boost.Chrono fails * Boost.Chrono zip contains changes for parts of Boost.Thread Are these still needed/compatible? Also (not related to 1.44, but also 1.41, at least), there are many warnings issued by the compiler. It seems to me that they are somehow related to the constructors of duration, but I haven't been able to figure them out. These also occur when compiling client code. A log file is attached.
