[random] Do all RNG implement a base class?
by Kasra (Math & ComSci) 20 Jun '08

20 Jun '08

Hi, I am currently working on some cryptography algorithms for boost, I need a class such that: template < class RNG > class wiper { private: static RNG default_rng; public: void wipe(void *buffer, std::size_t count, RNG& specific_rng = default_rng) { . . . if( some_thing_is_true ) specific_rng.get_the_next_number_in_sequence(); . . } }; So I would like a provide the class with a template class (RNG) that is the base of random number generation. However, I looked at random number generators on [boost][random] but they don't seem to implement a base class! Am I right or I have mised something? regards

Workaround for a msvc 7.1 & 8.0 bug surfaced in the boost 1.35 release part II
by Okko Willeboordse 19 Jun '08

19 Jun '08

Hi all, Boost 1.35 triggers msvc 7.1 & 8.0 to export a local type named CRITICAL_SECTION declared in detail/lwm_win32_cs.hpp into the global namespace. This causes 'ambiguous identifier' compiler errors upon attempts to use (the global Windows type) CRITICAL_SECTION. Please refer to; [boost.pool] Workaround for a msvc 7.1 & 8.0 bug surfaced in the boost 1.35 release 4/8/2008 3:52 PM and; Changeset link: http://svn.boost.org/trac/boost/changeset/44480 Above fixes problems caused by usage of CRITICAL_SECTION in Boost itself namely in pool/detail/mutex.hpp. However usage of CRITICAL_SECTION outside Boost still gives problems. For example; #include <boost/archive/text_iarchive.hpp> typedef int CRITICAL_SECTION; CRITICAL_SECTION cs; or (real live case); #include <boost/archive/text_iarchive.hpp> #include <atlcore.h> Results in 'ambiguous identifier' compiler errors. I attached a patch of detail/lwm_win32_cs.hpp that fixes this. Note that; 1. a real solution to the problem would be to alter Boost such that the VS compiler bug is no longer triggered. 2. more local types, other then CRITICAL_SECTION, may have the same problem.

The tests have lines like BOOST_CLASS_TRACKING(list<int>, track_never) Are you saying that removing that line could improve the performance results of B.Serialization? >Versioning provides the facitly for remaining >backward compatibility with older archives.

I didn't know there is a way to disable your versioning stuff. How do you do it for a list<int>? We have a different approach to version support than you do. I've gone into some detail on the differences between our approaches on various C++ related newsgroups in the past. > But still I think, that such a limited > set of tests can provide only limited insight. Yes, someone else on the list said something similar previously. Since he said that we've started running the tests on Windows as well as Linux. I hope to add to the tests in the future.

I agree that vector and C-arrays are used heavily in some domains. But there are high performance applications that can't use those exclusively. Brian Wood www.webEbenezer.net

Hi, I'm using boost.exception from trunk and I get following error (gcc-4.2.4): error: request for member 'what' is ambiguous /usr/include/c++/4.2/exception:64: error: candidates are: virtual const char* std::exception::what() const /opt/boost/include/boost-1_35/boost/exception/exception.hpp:52: error: virtual const char* boost::exception::what() const I'm using the code from the boost.exception tutorial: class error : public boost::exception, public std::exception {} ... try {...} catch ( error const& e) { std::cout << "error: " << e.what() << std::endl; } // solves the error class error : public boost::exception, public std::exception { public: char const * what() const throw() { return boost::exception::what(); } }; Oliver

[format] Compiler error when using the Sun compiler.
by Sid Sacek 18 Jun '08

18 Jun '08

Can someone please assist? This code below doesn't compile when I use the Sun compiler. My company is currently using boost 1.33.0, and I cannot do anything about that, but I want to use boost::format. What modification can I make to the format files to fix this issue? Thanks, -Sid Sacek #include <boost/format.hpp> int main( int, char ** ) { boost::format fmt( "test %d %d\n" ); } [[[ The error: ]]] "/data/thirdparty/suncc/32/boost_1_33_0/include/boost/format/alt_sstream_impl.hpp", line 248: Error: Cannot assign void* to char*. Where: While instantiating "boost::io::basic_altstringbuf<char, std::char_traits<char>, std::allocator<char>>::overflow(int)". Where: Instantiated from non-template code. 1 Error(s) detected.
