[math] Warning in math/common_factor_rt.hpp
by Gabriel Redner 01 Jul '10

01 Jul '10

Hi all, I am getting a warning in math/common_factor_rt.hpp when compiling some code which includes boost headers: cc1plus: warnings being treated as errors /build/toolchain/lin32/boost-1.42.0/include/boost/math/common_factor_rt.hpp: In member function 'char boost::math::detail::gcd_optimal_evaluator<char>::operator()(char, char) const': /build/toolchain/lin32/boost-1.42.0/include/boost/math/common_factor_rt.hpp:329: warning: comparison is always false due to limited range of data type /build/toolchain/lin32/boost-1.42.0/include/boost/math/common_factor_rt.hpp:329: warning: comparison is always false due to limited range of data type Unfortunately that's all the compiler prints - nothing which ties the warning back to any particular piece of my code. None of my code is using the math library directly, though the .cpp being compiled here does include (mostly indirectly) a lot of boost headers. These include multi_index, optional, some MPL and type_traits, range, iterator, and probably others I am not seeing. Any suggestions on how to work around this? Is it possible to disable this warning? I'm using boost 1.42.0 and i686-linux-g++ (GCC) 4.1.2 Thanks, -Gabe

(oops) Boost Test with multiple processes (MPI)
by James Amundson 01 Jul '10

01 Jul '10

Sorry, I accidentally hit send too early... Does anyone have a solution for writing unit tests with Boost Test that run in multiple processes? I am using MPI, but I think the same problem would appear in other multi-process situations. I need some way to collect whether, e.g., BOOST_CHECK, has passed on all processes. Here's a simple example. I want my "example" test to fail because should_be_true is false on process 1. What happens is that I get success on process 0 and failure in process 1. What I want is a way to make the test fail on all processes. #define BOOST_TEST_MAIN #include <boost/test/unit_test.hpp> BOOST_AUTO_TEST_CASE(example) { double should_be_unity; const double tolerance = 1.0e-10; // do something that sets should_be_unity to 1.0 // in process 0, and 1.1 in process 1. BOOST_CHECK_CLOSE(should_be_unity, 1.0, tolerance); } I then run the test with mpirun -np 2 ./mytest Obviously, I could write my own tests and collect the results, but then I couldn't use the built-in macros like BOOST_CHECK_CLOSE. Thanks for any advice. --Jim Amundson

[Serialization] Runtime error
by Ernst, Jan (SCR US) 01 Jul '10

01 Jul '10

Hi, I am getting a runtime error when using boost::serialization, using MSVC 2008, boost 1.43. The code looks something like the following: SomeData some_data; std::ofstream ofs(pcConfigFile, std::ofstream::trunc | std::ofstream::out); boost::archive::xml_oarchive xml(ofs,boost::archive::no_codecvt); xml << boost::serialization::make_nvp("data", some_data); Where some_data is a class that declares serialize. In Debug mode, this results in a exception with the below lengthy stack trace. The Release mode works fine. Any ideas where this could come from? Are there any special considerations that I have to take into account in serialization that do not lead to compile errors but might lead to this runtime behaviour? As a side note, if I do not set the boost::archive::no_codecvt flag in the above code,the constructor of xml_oarchive already fails at a different spot. I already spent days on this, to no avail. I've tried using Intel C++ 11.1, with the same result. Google did not reveal any relevant discussion, the serialization documentation didn't shed light on this either. > XMLTester.exe!boost::archive::iterators::xml_escape<char const *>::fill(const char *

bitsets in ITL
by Amir Gonnen 01 Jul '10

01 Jul '10

I'm evaluating ITL (Interval Template Library which was recently accepted to boost) in order to represent sparse bitsets. In the current implementation the large_bitset class is given as an example with minimal functionality. Are there any plans to develop it into a fully featured bitset and make it a part of boost? It would be nice if it implemented the interface of dynamic_bitset, to ease the migration between dynamic_bitset and large_bitset. Amir

[boost-users][unit-test-framework] Problem linking tests.
by Germán Diago 01 Jul '10

01 Jul '10

Hello all. I'm having a hard time trying to link a binary against libbost_unit_test_framework. I was developing some software in my laptop. This laptop has installed boost libraries from the repositories (it's boost-1.40 ubuntu 10.04). I had to pass this code to another computer, which hadn't boost installed, so I copied what I had in ubuntu from the repositories into my project, headers included. My project uses boost_system and boost_thread as well. Both machines are 64 bit machines with intel. But when compiling, I get this: td::char_traits<char> >::_M_extract<unsigned long>(unsigned long&)(a)GLIBCXX_3.4.9' /home/gdiago/clientserver/deps/boost-1.40/lib/libboost_unit_test_framework.so: undefined reference to `std::basic_ostream<char, std::char_traits<char> >& std::basic_ostream<char, std::char_traits<char> >::_M_insert<bool>(bool)(a)GLIBCXX_3.4.9' /home/gdiago/clientserver/deps/boost-1.40/lib/libboost_unit_test_framework.so: undefined reference to `std::basic_ostream<char, std::char_traits<char> >& std::__ostream_insert<char, std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&, char const*, long)(a)GLIBCXX_3.4.9' /home/gdiago/clientserver/deps/boost-1.40/lib/libboost_unit_test_framework.so: undefined reference to `std::basic_istream<char, std::char_traits<char> >& std::basic_istream<char, std::char_traits<char> >::_M_extract<long>(long&)(a)GLIBCXX_3.4.9' /home/gdiago/clientserver/deps/boost-1.40/lib/libboost_unit_test_framework.so: undefined reference to `std::basic_ostream<char, std::char_traits<char> >& std::basic_ostream<char, std::char_traits<char> >::_M_insert<void const*>(void const*)(a)GLIBCXX_3.4.9' /home/gdiago/clientserver/deps/boost-1.40/lib/libboost_unit_test_framework.so: undefined reference to `std::ctype<char>::_M_widen_init() const(a)GLIBCXX_3.4.11' /home/gdiago/clientserver/deps/boost-1.40/lib/libboost_unit_test_framework.so: undefined reference to `std::basic_istream<char, std::char_traits<char> >& std::basic_istream<char, std::char_traits<char> >::_M_extract<unsigned int>(unsigned int&)(a)GLIBCXX_3.4.9' /home/gdiago/clientserver/deps/boost-1.40/lib/libboost_unit_test_framework.so: undefined reference to `std::basic_ostream<char, std::char_traits<char> >& std::basic_ostream<char, std::char_traits<char> >::_M_insert<unsigned long>(unsigned long)(a)GLIBCXX_3.4.9' /home/gdiago/clientserver/deps/boost-1.40/lib/libboost_unit_test_framework.so: undefined reference to `std::basic_istream<char, std::char_traits<char> >& std::basic_istream<char, std::char_traits<char> >::_M_extract<bool>(bool&)(a)GLIBCXX_3.4.9' /home/gdiago/clientserver/deps/boost-1.40/lib/libboost_unit_test_framework.so: undefined reference to `__longjmp_chk(a)GLIBC_2.11' I also tried to compile my code with version 3.4 of g++, which is installed in the machine with no luck, same errors. Can anyone tell me if this is solvable without recompiling boost in the target machine? I'm not the mantainer of that machine, so I can't install boost. Thanks in advance.

boostMPI asychronous communication
by Jack Bryan 01 Jul '10

01 Jul '10

Dear All: How to do asychronous communication among nodes by boot.MPI or OpenMPI in cluster ? I need to set up a kind of asychronous communication protocol such that message senders and receivers can communicate asychronously without losing anymessages between them. I do not want to use blocking MPI routines because the processors can do otheroperations when they wait for new messages coming. On boost.org, I donot find this kind of MPI routines that support this asychronous communication. Any help is appreciated. thanks Jack June 27 2010 _________________________________________________________________ The New Busy is not the too busy.

Boost 1.28.0 and Visual C++ 2010
by Gregory Tyler 01 Jul '10

01 Jul '10

Hi, I'm trying to migrate a Visual C++ 6 workspace to Visual C++ 2010. When I try to compile the resulting solution, I get error messages like these: Unknown compiler version - please run the configure tests and report the results With the help of this page... http://social.msdn.microsoft.com/forums/en-US/vcgeneral/thread/09fa47e5-6e9… ...I've traced the problem to a compiler version check in boost/config/compiler/visualc.hpp: #define BOOST_COMPILER "Microsoft Visual C++ version " BOOST_STRINGIZE(_MSC_VER) // // versions check: // we don't support Visual C++ prior to version 6: #if _MSC_VER < 1200 #error "Compiler not supported or configured - please reconfigure" #endif // // last known and checked version is 1301: #if (_MSC_VER > 1301) # if defined(BOOST_ASSERT_CONFIG) # error "Unknown compiler version - please run the configure tests and report the results" # else # pragma message("Unknown compiler version - please run the configure tests and report the results") # endif #endif According to this page... http://msdn.microsoft.com/en-us/library/b0084kay.aspx ... _MSC_VER for Visual C++ 2010 is 1600. If I were to modify the version checking code in visualc.hpp, then would you anticipate problems? For a variety of reasons, I would like to avoid upgrading Boost if at all possible. Thanks, Greg _________________________________________________________________ The New Busy think 9 to 5 is a cute idea.
