Hi, The Boost.Trunk summary now gives for some Intel compilers, since some time: Test output: Sandia-intel-10.1 - geometry - distance / intel-darwin-10.1Rev 70458 / Wed, 23 Mar 2011 01:41:17 +0000 Report Time: Thu, 24 Mar 2011 07:47:34 +0000 Compile [2011-03-23 04:42:50 UTC]: fail "/opt/intel/cce/10.1.024/bin/icpc" -xc++ -w1 -O0 -g -inline-level=0 -vec-report0 -DBOOST_ALL_NO_LIB=1 -D__WINT_TYPE__=int -I".." -I"../boost/geometry/extensions/contrib/ttmath" -I"../libs/geometry/test" -c -o "/Volumes/Scratch/kbelco/boost/results/boost/bin.v2/libs/geometry/test/algorithms/distance.test/intel-darwin-10.1/debug/distance.o" "../libs/geometry/test/algorithms/distance.cpp" ../boost/detail/fenv.hpp(11): catastrophic error: #error directive: This platform does not have a floating point environment #error This platform does not have a floating point environment ^ compilation aborted for ../libs/geometry/test/algorithms/distance.cpp (code 4) Meaning the boolean variable BOOST_NO_FENV_H is not set. Is that compiler-detection broken somehow? It is not on all Intel compilers. Regards, Barend
