Shmem minor bug in Deque container
by Ryan, Paul L. 09 Mar '06

09 Mar '06

I'm no sure if this is the proper forum for this so if it is not feel free to let me know an I'll put it where it belongs. But I've found a minor error in the recently reviewed boost shmem stuff (which I realize has not been integrated yet but I can't find contact info for the group dealing with that utility). The error found was an exculsion of the include file <boost/detail/allocator_utilities.hpp> from <boost/shmem/containers/deque.hpp>. Thank you for your time. Paul Ryan SAIC - Tactical Systems

Unzip 5.42 complained about "unknown method 12". Unzip 5.52 says (much less helpfully) "'(null)' method not supported". Wikipedia suggests that (some) people are using method 12 for bzip2.

[bitfield] More portable implementation available in the vault
by Emile Cormier 09 Mar '06

09 Mar '06

Bitfield2.zip in http://boost-consulting.com/vault/index.php?direction=0&order=&directory=bi… For now, I didn't bother to adapt my code to Boost's style. I'm using this stuff at work where we have a different coding style. Check out the html folder for the doxygen page, which shows usage examples. I removed Bitfield::operator(), as its purpose was not self-evident. I think this version will not suffer from memory alignment/padding problems as did the previous version. The test code runs fine with GCC MinGW 3.4. I plan on using it on an ARM platform, so I'll confirm if it runs okay on that platform too. Bitfield now accepts a 4th template parameter, R, which is the reference type used by Bitfield to manipulate the word. The only requirements on this reference type are: - Has a default or copy constructor, depending on how you use it - Can be assigned a value of type T - Can be evaluated as a value of type T By default, R=T&, which is convenient for manipulating regular non-I/O-mapped integers. I demonstrate in PortExample.hpp how Bitfield can be used with special types which can interface to memory-mapped I/O ports. I've just read the n1666 "Technical Report on C++ Performance", and it seems like Bitfield would be ready to support the use of <iohw.h> ports. I need to study the proposed <iohw.h> some more to fully understand it, though. I will inspect mixed source+assembly to confirm that this Bitfield mechanism is as efficient as hand-written bit-manipulations. -- Emile Cormier emilecormier(a)mailcan.com

bcbboost version 0.3 released
by Nicola Musatti 09 Mar '06

09 Mar '06

Hallo, I'd like to inform those of you that use Boost with Borland's BCB2006 product that I just released version 0.3 of bcbboost - the unofficial BCB Boost patches. This is a set of modified sources from Boost 1.33.1 that allow you to build and use some of the libraries from that release with the latest Borland compiler, bcc32 5.8.1 . Bcbboost is available from SourceForge: http://bcbboost.sourceforge.net/ This release contains improvements to date_time, call_traits, compressed_pair, math/octonion, numeric/conversion, optional, random and type_traits. Changes impact also graph, format and possibly other libraries. Many thanks to Alisdair Meredith: most of this release is a backport of the work he's done to add BCB2006 support to Boost's mainline.

[filesystem] static object throws
by Vladimir Prus 09 Mar '06

09 Mar '06

Hi, an application of mine just suddenly crashed before entering 'main', with the following stacktrace: #5 0xb7eb7106 in __cxa_throw () from /usr/lib/libstdc++.so.5 #6 0xb7e6ccb0 in std::__throw_runtime_error () from /usr/lib/libstdc++.so.5 #7 0xb7eb5c8e in std::locale::facet::_S_create_c_locale () from /usr/lib/libstdc++.so.5 #8 0xb7e96554 in std::locale::_Impl::_Impl () from /usr/lib/libstdc++.so.5 #9 0xb7e768e9 in std::locale::locale () from /usr/lib/libstdc++.so.5 #10 0xb78f6922 in __static_initialization_and_destruction_0 (__initialize_p=1, __priority=65535) at /space/NM/boost/libs/filesystem/src/path.cpp:29 And the line in question contains just: 29 std::locale loc(""); This is CVS as of today. The problem was that I incorrectly set the LC_MESSAGES environment variable. However, I think that exception from static object is not so good idea. I can't catch it, so the error reporting just reads "Aborted". Maybe, this can be converted into a function with static variable, so that the static variable is only initialized on the first call? TIA, Volodya

The following is a shot in the dark. Can replace your typedef headers_multi_index_t::nth_index<1>::type::iterator iterator; with something like typedef headers_multi_index_t::nth_index<1>::type::iterator my_iterator; // note, name changed adjust the dependent typedefs and try to compile? Older versions of GCC have sometimes clashing symbol problems with symbols that ought not to clash. Additionally, I'd check the using decls and directives in effect. If this does not shed any light, it'd be extremely helpful if you can isolate the problem into a complete testcase you can post or send to me. I've tried myself to reproduce the issue following your general code outline, but didn't get the compiler to choke as you have reported. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
