Utility/swap test error: LNK1561: entry point must be defined
by Kevin Li 05 Feb '10

05 Feb '10

Hi there, I got linking failures (fatal error LNK1561: entry point must be defined) with some of the Utility/swap tests. There is a test_main function in the source file, and the test application statically links to the Boost library. It seems that the Utility/swap tests try to link to boost_test_exec_monitor library. I have the library "libboost_test_exec_monitor-vc90-mt-1_41.lib" ready. I have no idea why the linking does not work. Is the problem with this library? I would appreciate any helps with this. The Ja Thanks in advance, Kevin _________________________________________________________________

linear algebra library... again
by DE 04 Feb '10

04 Feb '10

"Yeah, well... I'm gonna go build my own theme park, with blackjack and hookers. In fact, forget the park!" it seems the previous message has not reached the list i hope this will i present you an almost finished linear algebra library called BIBLAL there are some aspects of matrix algebra implemented as well the sources and docs are in the vault:/linalg/ http://www.boostpro.com/vault/index.php?direction=0&order=&directory=linalg& to this moment the core of the library is fully working it turned out to be almost 100% the way i originally intended so i'm very happy about it there are some minor details to implement as well as some usefull features to add but this seems trivial when the core is finished although i think a linear algebra lib should never be part of the standard, the boost collection of libraries will certainly benefit from its inclusion to complement ublas i'm open to questions, criticism and suggestions -- Pavel

[1.42.0][integer] Compilation error in MS VS 2005
by Adam Badura 04 Feb '10

04 Feb '10

Problem described by Ticket #3657 was solved by version 1.42 only for Visual Studio 2008. In Visual Studio 2005 it still exists. So I reopened the bug with appropriate description (https://svn.boost.org/trac/boost/ticket/3657#comment:2) Is it possible to release 1.42.1 version correcting the bug? Or do I have to wait again 2 months (at least) for 1.43 which will (possibly) solve the bug? I still have to use 1.39 since starting from 1.40 there are problems with Integer library. Adam Badura

[serialization] basic_binary_oarchive.hpp asserts are no longer necessary
by Number Cruncher 04 Feb '10

04 Feb '10

I've just tried building my code against 1.42 and am encountering numerous warnings of the sort: boost/archive/basic_binary_oarchive.hpp:95: warning: comparison is always true due to limited range of data type I've checked the difference to the 1.41 release and noticed that boost/archive/basic_archive.hpp now uses BOOST_ARCHIVE_STRONG_TYPEDEF for class_id_type etc. and uses int_least16_t rather than "int". This is causing my GCC 4.1.2 compiler to produce the above warning because the assertion "t.t <= boost::integer_traits<boost::int_least16_t>::const_max" is always true when t.t *is* an int_least16_t The attached patch removes the (now redundant) asserts.

[gil] trac #3619
by Christian Henning 03 Feb '10

03 Feb '10

Hi there, could someone please tell whether or not this bug still exists. I don't have access to gcc 4.4. This is marked as a showstopper and I would like to get rid of it. Is it a compiler bug maybe? Thanks, Christian

[multi_index][serialization] save_construct_data not called for multi_index collection
by Felipe Magno de Almeida 03 Feb '10

03 Feb '10

Hi, Boost.Serialization has support for non-default classes using save_construct_data and load_construct_data overloads. These are called before serialization to save and load information that's important for the construction of the object. Unfortunately, multi_index doesn't call these functions when serializing, so serialization of non-default-constructible classes is impossible with multi_index. I wanted to patch it so that it becomes possible, but to be honest I'm a bit lost in the serialization code for multi_index. collections_save_impl calls boost::serialization::save_construct_data_adl before serializing each item in the collection. I'm using boost 1.38.0, is there anyway to do the same for multi_index? Thanks in advance, -- Felipe Magno de Almeida

errors in Math Toolkit documentation
by Shawn Pautz 03 Feb '10

03 Feb '10

The documentation for the Poisson distribution in boost/math/distributions (http://www.boost.org/doc/libs/1_41_0/libs/math/doc/sf_and_dist/html/math_to…) contains a few errors. In the middle of the page is a bar graph depicting the Poisson distribution for several values of lambda. The one labeled for lambda=1 is actually the distribution for lambda=5. Similarly the one labeled as lambda=50 appears to be generated for lambda=20 instead. Please check this and correct as needed. Shawn Pautz
