[Boost-users] Linux build of boost using Intel C++ compiler 11.1 or 11.0 and g++ 4.3.3

Hi, I guess this may be a known problem but I wonder if there is any straightforward workaround. I need to install boost on our development machines which run Linux and have g++ 4.3.3 installed. We are wondering about also support the Intel c++ compiler (version 11.1). When trying to build boost 1.39 we get many errors during compilation due to g++ builtins like __builtin_isfinite not being found. Example below. Perhaps I've missed something but using the intel toolset when building still seems to involve using these g++ specific features. Is there a workaround? Thanks Bill For example: "icpc" -c -xc++ -O3 -w1 -inline-level=2 -pthread -fPIC -DBOOST_ALL_NO_LIB=1 -DBOOST_MATH_TR1_DYN_LINK=1 -DNDEBUG -I"." -c -o "bin.v2/libs/math/build/intel-linux-11.1/release/threading-multi/lround.o" "libs/math/build/../src/tr1/lround.cpp" ...failed intel-linux.compile.c++ bin.v2/libs/math/build/intel-linux-11.1/release/threading-multi/lround.o... intel-linux.compile.c++ bin.v2/libs/math/build/intel-linux-11.1/release/threading-multi/nextafter.o /usr/include/c++/4.3.3/cmath(522): error: identifier "__builtin_isfinite" is undefined return __builtin_isfinite(__type(__f)); ^ detected during: instantiation of "__gnu_cxx::__enable_if::__value, int>::__type std::isfinite(_Tp) [with _Tp=double]" at line 262 of "./boost/math/special_functions/fpclassify.hpp" instantiation of "bool boost::math::detail::isfinite_impl(T, const boost::math::detail::native_tag &) [with T=double]" at line 310 of "./boost/math/special_functions/fpclassify.hpp" instantiation of "bool boost::math::isfinite(T) [with T=double]" at line 56 of "./boost/math/special_functions/next.hpp" instantiation of "T boost::math::float_next(const T &, const Policy &) [with T=double, Policy=c_policies::c_policy]" at line 153 of "./boost/math/special_functions/next.hpp" instantiation of "T boost::math::nextafter(const T &, const T &, const Policy &) [with T=double, Policy=c_policies::c_policy]" at line 27 of "libs/math/build/../src/tr1/c_policy.hpp" instantiation of "T c_policies::nextafter(const T &, const T &) [with T=double]" at line 15 of "libs/math/build/../src/tr1/nextafter.cpp" compilation aborted for libs/math/build/../src/tr1/nextafter.cpp (code 2)
