After figuring out the rudiments of bjam, I have released a version of the Probability library in the Boost Vault:
boost.probability-0.2.1.tar.gz
My hope is that this makes it much easier to integrate into an existing Boost system for testing and use. I would greatly appreciate any comments and helpful suggestions for improvement. Once again, the main documentation is available at
http://biology.nmsu.edu/software/probability/
Thank you very much for any helpful reviews.
As usual, bjam produced a myriad of error messages. For MSVC 8.0 1 I found I needed to suppress // Need to suppress warning in all examples until boost/concept_check.hpp does it (ticket #813). #ifdef _MSC_VER # pragma warning(disable: 4100) // 'b' : unreferenced formal parameter #endif 2 return probability(exp(-lambda) * pow(lambda, static_cast<double>(i)) / factorial(i)); static_cast to double or int - MSVC does not specialise for unsigned int (and say that one should not). int probably best? 3 Tests don't work with 1_34_0 version of tests. #define BOOST_TEST_MODULE probability_tests in place of #define BOOST_AUTO_TEST_MAIN and #define BOOST_TEST_DYN_LINK and BOOST_AUTO_UNIT_TEST to BOOST_AUTO_TEST_CASE (test_validator_concept) ... throughout. 4 log1p is not provided by MSVC math.h, but I added #include <boost/math/special_functions/log1p.hpp> using boost::math::log1p; 5 I had to replace log(v) and exp(v) with casts like exp(static_cast<Value>(v) to avoid ambiguity. Autorun "j:\cpp\probability\prob\debug\probability_test.exe" Running 24 test cases... *** No errors detected for debug and release :-)) But I also don't see why // XXX - why can't operator<<(std::ostream&, ...) be used? You have disabled this with //BOOST_TEST_DONT_PRINT_LOG_VALUE (likelihood); likelihoods.cpp I:\boost_1_34_0\boost/test/test_tools.hpp(298) : error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'const likelihood' (or there is no acceptable conversion) C:\Program Files\Microsoft Visual Studio 8\VC\include\ostream(650): could be 'std::basic_ostream<_Elem,_Traits> &std::operator <<<char,std::char_traits<char>>(std::basic_ostream<_Elem,_Traits> &,const char *)' [found using argument-dependent lookup] with [ _Elem=char, _Traits=std::char_traits<char> ] ... Example 2 produces many warnings 'initializing' : conversion from 'const double' to 'float', possible loss of data that I presume are expected as value is of type float. Example 6 produces warning C4101: 'c' : unreferenced local variable that could be commented out example 5 I'm a bit puzzled what it does/shows - none of the functions are called? Examples 6 lots of errors like ..\..\libs\probability\test\example6.cpp(139) : error C2039: 'universal_time' : is not a member of 'boost::posix_time' ..\..\libs\probability\test\example6.cpp(139) : error C3861: 'universal_time': identifier not found ..\..\libs\probability\test\example6.cpp(143) : error C3083: 'microsec_clock': the symbol to the left of a '::' must be a type Is this a change in 1_34_0? I will investigate but suggestions? I am also re-reading the documentation ;-) And Finally I note the thorough - indeed exemplary - use of testing and concepts :-) Paul --- Paul A Bristow Prizet Farmhouse, Kendal, Cumbria UK LA8 8AB +44 1539561830 & SMS, Mobile +44 7714 330204 & SMS pbristow@hetp.u-net.com
