Intel Compiler on Windows with stlport
by Marco Azimonti 07 Dec '05

07 Dec '05

Hello, I am recently moving from Microsoft to Intel C++ Compiler on windows. Currently I am as well using (|vc-7_1-stlport|) stlport. On the boost documentation page for intel Compiler (http://www.boost.org/tools/build/v1/intel-win32-tools.html) is written that the base toolset for it could |msvc|, |vc7|, or |vc-7_1|. However, |vc-7_1-stlport| is not mentioned. If I set the base toolset |INTEL_BASE_MSVC_TOOLSET| to |vc-7_1-stlport |(and setting the proper stlport options) the build does not produce any error, but I am not sure it is compiling what I want.. ;) It is that enough or do I have to modify the procedure in some way? Thank you in advance, Marco .. http://www.murex.com/webdoc/MUREXTopTechnologyVendor.pdf

I keep on getting the error: c:\temp\boost\boost_1_33_0\boost/type_traits/is_abstract.hpp(81): error: incomplete type is not allowed BOOST_STATIC_ASSERT(sizeof(T) != 0); ^ detected during: instantiation of class "boost::detail::is_abstract_imp2<T> [with T=TxsOqSourceMaterialization]" at line 121 I checked that I have put the appropriate archive statement in class.

assignment library with functors

Dear all, I am too tired to investigate it deeply, so does anyone know why this does not compile (on VS 2003): typedef boost::function<int (const int& , const int&)> BinOperand; typedef std::vector<BinOperand> BinOperandVector; BinOperandVector operands = boost::assign::list_of(std::plus<int>()) (std::minus<int>()) (std::multiplies<int>()) (std::divides<int>()); Wkr, me

E.g., on the C++ side I might have an instance x of class X, which contains a vector of shared_ptrs p1,...,pn to instances y1,...,yn of another C++ class Y. At pickle-time there may be Python object z with a member u bound to to x and members w1,...,wm bound to a subset of the y1,...,yn. Is it even feasible to expect to be able to simple pickle.dump z and have it all work? Please keep in mind: I am just getting started wading into serializing a pretty complicated set of strongly interdependent Python and C++ objects and I am just trying to get my bearings.

threads - thread_resource_error thrown by creating more than 256 threads
by Oliver.Kowalke＠infineon.com 06 Dec '05

06 Dec '05

Hi, if I try to create more than 255 threads (256 for instance) I get the exception thread_resource_error thrown. How can I increase the amount of threads? My System: Linux 2.4.21, gcc 3.3.1 (posix thread model). cat /proc/sys/kernel/threads-max --> max 12152 threads per process currently allowed With best regards, Oliver

Wave: how to recover after errors?
by Max Motovilov 06 Dec '05

06 Dec '05

I have a simple problem: wave warnings (specifically, macro re-definition) are reported as exceptions thrown from [potentially, any of, at least I don't yet know better] the methods of pp_iterator. It is very simple to catch one and print a message, however I can't figure out how to recover after one. Can't seem to find any mention of error recovery in documentation, tried some variations of last_known_good_iterator (store a copy before every increment, restore back to known copy in exception handler) -- it recovers simple cases but on more complex files there appears to be internal state corruption. Also, even when this recovery works, it leaves macro in the pre-redefinition state whereas the usual cpp policy is to allow redefinition and print a warning. I thought of using a preventive strategy -- undefine the existing macro from a policy method -- but unfortunately the exception is thrown before defined_macro() is called. Looks like it's time to ask the owners of the library: how do I do this? :-) Thanks in advance, ...Max... PS. I am using 1.33.0; should I _really_ _really_ be upgrading to 1.33.1 to get this resolved?

[serialization] seriazation from base pointer / Runtime Casting
by __PPS__ 06 Dec '05

06 Dec '05

is it possible to have this exported from dll: ///export.h/// #include <boost/serialization/serialization.hpp> class session_record { virtual void print_on(std::ostream& os) const = 0; friend std::ostream & operator<<(std::ostream& os, const session_record& sr){ sr.print_on(os); return os; } public: friend class boost::serialization::access; virtual ~session_record(); template<class Archive> void serialize(Archive & ar, const unsigned int file_version){} operator session_record *(); }; void serialize(session_record* derived, const char* file_name); session_record* deserialize(const char* file_name); ///end of export.h/// and then in an application (linked to the dll that exports all from export.h) I create derived classes from session_record and serialize or deserialize them to/from files using the two exported free functions. I followed exactly steps in "Runtime Casting" of the manual, but it doesn't work. So... is it really runtime if it doesn't work this way - it only works if all the derived classes are known & registered at the time of compilation of the two functions. All that worked well if everything from export.h was linked statically, but not dynamically Am I doing something wrong with all that stuff?? thanks

STLPort & VC++ 8?
by Jerker Öhman 06 Dec '05

06 Dec '05

Does anyone know if there are plans to support STLPort 5 with Visual C++ 8? Although Microsoft know ships a good implementation of STL, STLPort is much faster and has a nice debug mode so I think it would be nice to continue to support it. /Jerker

Implementing an Event class
by Raffaele Romito 06 Dec '05

06 Dec '05

Hi, I need to implement an Event class around (I suppose) boost::condition. The class needs the follow interface class Event { public: Event(); ~Event(); public: void reset(); void signal(); void wait(unsigned int ms = 0); // 0 = infinite }; Any advice? Thanks
