[date_time] gcc 3.4.6 - int_adapter<T>::from_special(special_values) is not inlined, so duplicated (#6302)
by Vicente J. Botet Escriba 20 Dec '11

Hi, I know that gcc 3.4.6 is an old compiler version, but there are a lot of error on the Boost.Thread regression tests. I have created a ticket #6302 <https://svn.boost.org/trac/boost/ticket/6302> int_adapter<T>::from_special(special_values) is not inlined, so duplicated. <https://svn.boost.org/trac/boost/ticket/6302> to follow this issue It seems that this function template<typename int_type_> class int_adapter { static int_adapter from_special(special_values sv) { switch (sv) { case not_a_date_time: return not_a_number(); case neg_infin: return neg_infinity(); case pos_infin: return pos_infinity(); case max_date_time: return (max)(); case min_date_time: return (min)(); default: return not_a_number(); } } is not been inlined with gcc 3.4.6 and so it is duplicated at link time.

[predef][review-request] Requesting a review of Predef library submission..
by Rene Rivera 20 Dec '11

20 Dec '11

I've completed doing a final pass at the documentation and code for the Predef library. And hence I'm requesting the library be placed in the review "queue" (aka the review bucket). For those who missed it.. The Predef library implements two simple tasks: 1. Definition of a single version number macro to provide consistent version number at the preprocessor level. 2. A collection of detected definitions for compilers, standard libraries, architectures, operating systems, and languages. Unlike the Boost Config Library it doesn't define language features and capabilities. But only defines presence of detected compilation context. Documentation and downloads are available in the sandbox.. * Documentation at <http://tinyurl.com/7yrodwx> * Subversion source at <http://tinyurl.com/75oggaq> * Zip with Windows EOLs at <http://tinyurl.com/6lt7pks> * Bz2 with Unix LF-EOLs at <http://tinyurl.com/73n6a3k> Rene. -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org (msn) - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim,yahoo,skype,efnet,gmail

Hello, I am a newbie in the world of testing and using boost. I went through some of the previous discussion on this topic with no luck at trouble shooting my current issue.

C:\Program Files (x86)\boost\boost_1_47 Now, when I try to run boost example I get the following error , No matter what I do I just cannot get rid of this error any help is greatly appreciated . 1>------ Build started: Project: UnitTestPrac1, Configuration: Debug Win32 ----- - 1>Linking... 1>LINK : fatal error LNK1104: cannot open file 'libboost_unit_test_framework- vc90-mt-gd-1_47.lib' 1>Build log was saved at "file://c:\Users\amaster\Desktop\AVM_Documents\CppPractise\UnitTestPrac1\UnitTes tPrac1\Debug\BuildLog.htm" 1>UnitTestPrac1 - 1 error(s), 0 warning(s) ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== // Following is my example #define BOOST_TEST_MODULE MyTest #include <boost/test/unit_test.hpp> BOOST_AUTO_TEST_CASE(MyTestCase) { // To simplify this example test, let's suppose we'll test 'float'. // Some test are stupid, but all should pass. float x = 9.5f; BOOST_CHECK(x != 0.0f); BOOST_CHECK_EQUAL((int)x, 9); BOOST_CHECK_CLOSE(x, 9.5f, 0.0001f); // Checks differ no more then 0.0001% } Thank you in advance.

[asio] running code before ssl initialization
by Isidor Zeuner 20 Dec '11

20 Dec '11

Hi, boost::asio::ssl::detail::openssl_init<true>::do_init initializes the SSL library using the static initialization hook, thereby preventing code being ran from main() which must be run before SSL initalization (for example custom allocators being set using CRYPTO_set_mem_functions). Is there an intended way to do so when using boost::asio::ssl? Best regards, Isidor

Boost compatible with Clang C++11 dialect?
by Torrey Lyons 19 Dec '11

19 Dec '11

When enabling C++11 support on Xcode 4.2 using Clang 3.0 there are many build conflicts in Boost. The C++11 language dialect is not on by default, but we would like to use it. Apparently Boost is not detecting that the compiler already has these features built in when C++11 support is turned on. Should we expect Boost 1.48.0 to work with Clang 3.0 using the C++11 language dialect? Is there a known workaround? Thanks for any tips or insights. -- Torrey VSee: torrey(a)vsee.com <http://vsee.com/call?torrey@vsee.com> | Cell: 310.940.6397 Teamwork made simple vsee.com Blog <http://vsee.com/blog/> Facebook <http://www.facebook.com/VSeeLab> Twitter <http://twitter.com/vsee>

[bind][phoenix] Compliance with function template bind
by Vicente J. Botet Escriba 19 Dec '11

19 Dec '11

Hi, Boosthas Boost.Bind and Boost.Phoenix that provides a bind function. Are them compliant with C++11 for 20.8.9 Function template bind (in particular move semantics)? If yes, how they work for C++03 compilers? If not, is there any plan to adapt them to support move semantics? Best, Vicente

[Concept Checking] function_requires
by Jens Müller 18 Dec '11

18 Dec '11

Hi all, as far as I understand http://www.boost.org/doc/libs/1_48_0/libs/concept_check/reference.htm#depre…, function_requires() is deprecated. However, the documentation does not mention very clearly how to replace it. Is the BOOST_CONCEPT_ASSERT macro the replacement? E.g., does function_requires< VertexListGraphConcept<Graph> >(); now become BOOST_CONCEPT_ASSERT((VertexListGraphConcept<Graph>)); function_requires still appears in a lot of test cases of the Graph library. So if it is that easy to change, I would hand in a patch. Best regards, Jens

[math.special_functions] broken in trunk
by Tim Blechmann 18 Dec '11

18 Dec '11

it seems, there is a problem in boost.math in trunk. the boost.heap testsuite originally used boost.random, but the test farm reports some issues: In file included from ../boost/math/special_functions.hpp:32, from ../boost/random/generate_canonical.hpp:22, from ../boost/random.hpp:52, from ../libs/heap/test/mutable_heap_tests.hpp:1, from ../libs/heap/test/fibonacci_heap_test.cpp:12: ../boost/math/special_functions/expint.hpp: In function ???void boost::math::detail::expint_i_imp_113a(T&, const T&)???: ../boost/math/special_functions/expint.hpp:1028: error: expected primary- expression before ???(??? token (compare http://tinyurl.com/bqfputx) for now, i've reverted to the libc random() function to work around this issue, but it would be great, if someone with insights in boost.math could have a look. thanks, tim
