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

Boost.Filesystem DLL builds on Mingw
by Alo Sarv 06 Dec '05

06 Dec '05

The topic itself is already few months old, namely the fact that Boost.Filesystem library breaks on Mingw in DLL builds. As I see from regression tests, this issue hasn't been fixed yet. The reason I'm bringing this up again is that while originally it was concluded that static builds should be used on Mingw instead of DLL builds, it is becoming an increasing problem for me, since default_name_check doesn't work across DLL boundaries when B.FS is linked statically to one of the DLL's, which results unexpected exceptions being thrown all over my codebase unless I explicitly construct paths using native name-checker, but tracking all those places is a constant headache. Is there any plans on addressing this issue, or are there any additional workarounds to have default_name_check functioanlity working across DLL boundaries when Boost.Filesystem is linked statically? My experience has been that mixing dynamic and static libraries is a really bad idea... Alo Sarv

[boost][lambda] additional placeholders
by Noel Belcourt 06 Dec '05

06 Dec '05

HI, I'm trying to extend the number of placeholders in boost lambda 1.33.0. There are three available by default and I need at least one more (_4) . I've followed the pattern establish for _3 to define _4, modifying the following files along the way. // lambda/core.hpp boost::lambda::placeholder3_type free3 = boost::lambda::placeholder3_type(); boost::lambda::placeholder4_type free4 = boost::lambda::placeholder4_type(); boost::lambda::placeholder3_type& _3 = free3; boost::lambda::placeholder4_type& _4 = free4; // lambda/detail/lambda_functors.hpp template<> struct placeholder<FOURTH> { template<class SigArgs> struct sig { typedef typename detail::get_element_or_null_type<3, SigArgs>::type type; }; template<class RET, CALL_TEMPLATE_ARGS> RET call(CALL_FORMAL_ARGS) const { CALL_USE_ARGS; return c; } }; typedef const lambda_functor<placeholder<THIRD> > placeholder3_type; typedef const lambda_functor<placeholder<FOURTH> > placeholder4_type; // lambda/detail/arity_code.hpp enum { NONE = 0x00, // Notice we are using bits as flags here. FIRST = 0x01, SECOND = 0x02, THIRD = 0x04, FOURTH = 0x08, EXCEPTION = 0x10, RETHROW = 0x20}; So now _4 is defined but I get compilation errors from boost/function/function_template.hpp when I attempt to use _4. Is there some change necessary to either lambda placeholders or to boost function to get it to work correctly? Thanks, -- Noel Belcourt // With the changes above, this code fails with the message below. #include <boost/function.hpp> #include <boost/lambda/bind.hpp> using namespace boost; using namespace

Automatically including libaries
by Chris Morley 06 Dec '05

06 Dec '05

Hi, this is a how-is-it-done question rather than a problem. Ive learnt a lot about c++ from using boost, but this one I just cant work out. I installed boost and it dumped all the libraries in c\boost\lib.Now I am slightly confused how I'm able to simply reference a header file in c:\boost\include\blahblah yet I don't have to include the specific libraries... somehow its done for me?! This is using visual studio, and whenever I have built lib files I have to include the header file as usual, but also have to explicitly drag the lib file into the project (or under the required libraries in the linker tab). Any idea how this is done? Would love to be able to do this with my libs! Cheers, Chris

[Announce] Boost 1.33.1 released
by Douglas Gregor 06 Dec '05

06 Dec '05

Boost 1.33.1, the latest version of peer-reviewed, portable C++ libraries, has been released. This is a bug fix release addressing many small problems with the 1.33.0 release. It is a recommended upgrade for all users of Boost 1.33.0. Boost is available at http://www.boost.org Updated Libraries include: * Any Library: Cast to reference types introduced in 1.33.0 is now documented on any_cast documentation page. * Config Library: Don't undef BOOST_LIB_TOOLSET after use. * Boost.Python: o The build now assumes Python 2.4 by default, rather than 2.2 o Support Python that's built without Unicode support o Support for wrapping classes with overloaded address-of (&) operators * Smart Pointer Library: Fixed problems under Metrowerks CodeWarrior on PowerPC (Mac OS X) with inlining on, GNU GCC on PowerPC 64. * Regex Library: Fixed the supplied makefiles, and other small compiler specific changes. Refer to the regex history page for more information on these and other small changes. * Iostreams Library: Improved the interface for accessing a chain's components, added is_open members to the file and file descriptor devices, fixed memory-mapped files on Windows, and made minor changes to the documentation. * Functional/Hash Library: Fixed the points example. * Multi-index Containers Library: Fixed a problem with multithreaded code, and other minor changes. Refer to the library release notes for further details. * Graph Library: o Fixed a problem with the relaxed heap on x86 Linux (fixes bug in dijkstra_shortest_paths). o Fixed problems with cuthill_mckee_ordering and king_ordering producing no results. o Added color_map parameter to dijkstra_shortest_paths. * Signals Library: Fixed problems with the use of Signals across shared library boundaries. * Thread library: read_write_mutex has been removed due to problems with deadlocks. * Wave library (V1.2.1) Fixed a couple of problems, refer to the change log for further details. Supported Compilers Boost is tested on a wide range of compilers and platforms. Since Boost libraries rely on modern C++ features not available in all compilers, not all Boost libraries will work with every compiler. The following compilers and platforms have been extensively tested with Boost, although many other compilers and platforms will work as well. For more information, see the regression test results. New for this release: Support for building with the newest STLport-5.0 was added. The support includes building with MinGW Runtime 3.8 plus STLport-5.0 improved to support wide character operations. Apple GCC 4.0, HP Tru64 C++, and Microsoft Visual C++ 8.0 are supported platforms. We have added an experimental autoconf-like configure script for Unix-like systems: run configure --help for more information. * Apple GCC 3.3, 4.0 on Mac OS X. * Borland C++ 5.6.4 on Windows. * GNU C++ 2.95.3 (with and without STLport), 3.2.x., 3.3.x, 3.4.x, 4.0.x on Windows, Linux and Solaris. * HP C++ for Tru64 UNIX 7.1. * Intel C++ 8.1, 9.0 on Windows, Linux. * Metrowerks CodeWarrior 8.3, 9.4, 9.5 on Mac OS X and Windows. * Microsoft Visual C++ 6.0 (sp5, with and without STLport), 7.0, 7.1, 8.0. Note: Boost does not support the non-standard "Safe" C++ Library shipping with Visual C++ 8.0, which may result in many spurious warnings from Boost headers and other standards- conforming C++ code. To suppress these warnings, define the macro _SCL_SECURE_NO_DEPRECATE. Acknowledgements Douglas Gregor managed this release. A great number of people contributed their time and expertise to make this release possible. Special thanks go to Aleksey Gurtovoy and Misha Bergal, who managed to keep the regression testing system working throughout the release process; David Abrahams, Beman Dawes, Aleksey Gurtovoy, Bronek Kozicki, Rene Rivera and Jonathan Turkanis for greatly improving the quality of this release; Rene Rivera for the new Boost web page design; and Zoltan "cad" Juhasz for the new Boost logo.
