[ 227 open bugs today, 225 yesterday ] If you are maintaining a library, and have not logged into the trac system at <http://svn.boost.org/trac/boost/>, please do so ASAP. Until you do that, no tickets can be assigned to you, and will remain under "None".

[thread] Lots of warings on MingW32?
by John Maddock 19 Oct '07

19 Oct '07

I'm getting lots of warnings of the kind: ../../../boost/thread/win32/basic_timed_mutex.hpp: In member function `void boost::detail::basic_timed_mutex::unlock()': ../../../boost/thread/win32/basic_timed_mutex.hpp:116: warning: integer overflow in expression >From gcc-mingw when using the new Boost.Thread, should I be concerned? Also from VC++ I see: ..\..\..\boost/thread/thread_time.hpp(33) : warning C4244: 'return' : conversion from '__int64' to 'unsigned int', possible loss of data ..\..\..\boost/thread/xtime.hpp(60) : warning C4244: '=' : conversion from '__int64' to 'boost::xtime::xtime_nsec_t', possible loss of data Which are rather annoying, Thanks, John.

[GIL] image analysis algorithms
by Michael Held 19 Oct '07

19 Oct '07

hi folks, what is planned for GIL in terms of image processing/analysis algorithms. (I haven't seen anything in svn) there might be night-long discussions about which algorithms are "standard" and should belong to GIL and which not. working more than three years with VIGRA I would miss most of its basic and sophisticated algorithms when migrating to boost::GIL. nobody wants to implement image labeling, seeded region growing or basic morphology again and again. I know that for most algorithms more or less efficient (sometimes even patented) versions exist and most image analysis experts will write their own. for a broader majority of people a basic repertoire of algorithms will ease the daily work-flow a lot. one idea could be to port some of VIGRAs algorithms to GIL?! cheers, michael

[intrusive] Last step for Tru64/CXX support.
by Markus Schöpflin 19 Oct '07

19 Oct '07

Hello, by now I have intrusive pass all regression tests locally. There is one modification left, which I'm not sure off, therefore I would like to ask for some advice before committing. All remaining failures are due to the implementation of offset_from_pointer_to_member(): template<class Parent, class Member> inline std::size_t offset_from_pointer_to_member( const Member Parent::* ptr_to_member) { #if ... // 1 return *(const std::ptrdiff_t*)(void*)&ptr_to_member; #elif ... // 2 const Parent * const parent = 0; const char *const member = reinterpret_cast<const char*>(&(parent->*ptr_to_member)); return std::size_t(member - reinterpret_cast<const char*>(parent)); #else ... // 3 return (*(const std::ptrdiff_t*)(void*)&ptr_to_member) - 1; #endif } Currently, variant #3 is chosen, which is obviously wrong. I tried both variant #1 and #2, and both seem to work for CXX. (All tests pass, no crashes.) So which variant should I choose? TIA, Markus

[Thread] Failed to Link libboost_thread-vc80-mt-1_34_1.lib for Itanium
by Djalma Rosa dos Santos Filho 19 Oct '07

19 Oct '07

Hi, I've taken the thread_specific_ptr for a quick bug fixing, the problem is that now I am not being able to build the application for IA64 anymore (x64/x86 versions are working smoothly for weeks). I am using Visual Studio 2005 SP1 and got the following errors and warnings: >libboost_thread-vc80-mt-1_34_1.lib(tss_pe.obj) : warning LNK4078: multiple '.CRT' sections found with different attributes (C0408040) >libboost_thread-vc80-mt-1_34_1.lib(tss_pe.obj) : error LNK2003: gp relative fixup to symbol not in short data section '_tls_used' >LINK : fatal error LNK1165: link failed because of fixup errors Can anyone shed light on this, please? Is there a chance that I made a mistake in the boost building for ia64? Any help will be appreciated. TIA Djalma

boost range doc error?
by Neal Becker 19 Oct '07

19 Oct '07

The (recent svn) docs for range talk about boost_range_{begin,end,size}. Should't that be just range_{begin,end,size}? Method 2: provide free-standing functions and specialize metafunctions This procedure assumes that you cannot (or do not wish to) change the types that should be made conformant to a Range concept. If this is not true, see method 1. The primary templates in this library are implemented such that certain functions are found via argument-dependent-lookup (ADL). Below is given an overview of which free-standing functions a class must specify to be useable as a certain Range concept. Let x be a variable (const or mutable) of the class in question. Function Related concept boost_range_begin(x) Single Pass Range boost_range_end(x) Single Pass Range boost_range_size(x) Forward Range boost_range_begin() and boost_range_end() must be overloaded for both const and mutable reference arguments.

Any reason for not using intrusive_ptr? Shared_ptr may be a low level part of Boost, but I'm not sure it should be lower level than this library. A library like this is overdue in my opinion.

PATCH: Various error and warning corrections (g++ 4.3.0 snapshot)
by Jens Seidel 19 Oct '07

19 Oct '07

Hi, I tried to compile most of Boost's code from trunk by including all header files (except */detail/* ones as I noticed that these are internal ones) together with a int main() {} body :-) I still need to improve my script a little bit but nevertheless I found still many errors and a few warnings. I attached a patch which fixes the most obvious ones. Affected libraries: archive asio bimap circular_buffer date_time format fusion logic numeric and token_functions.hpp (don't know to which library it belongs). I used the following g++ snapshot g++ (Debian 20070916-1) 4.3.0 20070916 (experimental) [trunk revision 128522] with the flags -Wall -pedantic -Wno-uninitialized -Wcast-align -Wpointer-arith -Wextra I really wonder why broken code can be committed. I will try to automate my test even more so that a svn pre commit hook script can be used ... If there are questions about the compiler output without the patch I can send you the necessary information. PS: I hope this is the right list. The "Welcome to the \"Boost\" mailing list" mail contained "This list is for discussion of the www.boost.org web site and its contents." and nothing about development of Boost. Jens

Vera++
by Maciej Sobczak 19 Oct '07

19 Oct '07

I'm pleased to announce the availability of Vera++: http://www.inspirel.com/vera/ Vera++ is a programmable tool for verification, analysis and transformation of C++ source code. It relies on embedded scripting language for rule definition to provide maximum flexibility and extensibility. This tool might be of interest to the Boost community for two reasons: First, it uses boost::wave for parsing code. I would like to thank Hartmut Kaiser for this masterpiece. The second reason is this: http://www.inspirel.com/vera/ce/demo.html ;-) -- Maciej Sobczak * www.msobczak.com * www.inspirel.com
