I went to the current SVN and updated the log1.hpp file in my Boost installation. The same error that I reported occurs. Going deeper into my Boost based project , I found that this particular error happens only when the Boost Rational Library is included. For example, this code works fine: #define BOOST_MATH_THROW_ON_DOMAIN_ERROR #include <boost/math/distributions/students_t.hpp> #include <boost/math/special_functions/log1p.hpp> #include <iomanip> using namespace boost::math; int _tmain(int argc, _TCHAR* argv[]) { double d = log1p(5.78); students_t_distribution<float> d3(12); } However, this one will prevent compiling: #define BOOST_MATH_THROW_ON_DOMAIN_ERROR #include <boost/rational.hpp> // <----- Causes Error #include <boost/math/distributions/students_t.hpp> #include <boost/math/special_functions/log1p.hpp> #include <iomanip> using namespace boost::math; int _tmain(int argc, _TCHAR* argv[]) { double d = log1p(5.78); students_t_distribution<float> d3(12); } Error is: C:\boost_1_34_0_beta\boost_1_34_0\boost\math\special_functions\log1p.hpp(83) : error C2784: 'boost::rational<IntType> boost::abs(const boost::rational<IntType> &)' : could not deduce template argument for 'const boost::rational<IntType> &' from 'boost::math::tools::promote_args<T1,T2,T3,T4,T5,T6>::type' with [ T1=double, T2=float, T3=float, T4=float, T5=float, T6=float ] It seems to me that boost\math\tools\promotion.hpp tool may need some fix to avoid this conflicting interaction between Boost::Rational and Boost::MathToolKit Leopoldo -----Mensaje original----- De: boost-bounces@lists.boost.org [mailto:boost-bounces@lists.boost.org] En nombre de John Maddock Enviado el: Sunday, July 01, 2007 11:01 AM Para: boost@lists.boost.org Asunto: Re: [boost] [math toolkit] Leopoldo Peralta wrote:
This Error occurs (MSVC 2003 + SP1) when calling boost::math::log1p
Hopefully this has been fixed in current SVN, see http://svn.boost.org/trac/boost/browser/sandbox/math_toolkit/boost/math/spec ial_functions/log1p.hpp If not, let me have a test case and I'll look into it.
