[Boost-users] [1.41.0] Intel 11.1 Linux vs. cmath header

[Richard Hadsell]

I am trying to build the Boost 1.41.0 libraries with an evaluation copy
of Intel C++ 11.1 for 64-bit Linux. My system is Fedora 12 with G++
4.4.3 installed as the default compiler. This fatal error is preventing
most of the libraries from building:

/usr/include/c++/4.4.3/cmath(500): error: identifier "__builtin_fpclassify" is undefined
return __builtin_fpclassify(FP_NAN, FP_INFINITE, FP_NORMAL,
^
detected during:
instantiation of "__gnu_cxx::__enable_if<std::__is_arithmetic<_Tp>::__value, int>::__type std::fpclassify(_Tp) [with _Tp=float]" at line 65 of "./boost/functional/hash/detail/hash_float.hpp"
instantiation of "size_t={unsigned long} boost::hash_detail::float_hash_value(T) [with T=float]" at line 282 of "./boost/functional/hash/hash.hpp"

I am building the libraries with this command:

bjam toolset=intel-linux threading=multi variant=release link=static,shared --stagedir=stageIF12 stage

Release notes seem to indicate that someone has successfully built Boost
libraries with Intel 11.1 and G++ 4.4.1 (whose cmath header looks the
same as for 4.4.3). I have not used the Intel compiler for several
years, so I may be missing something that is familiar to other users.

Help?

That's definitely the problem. Thanks for the pointer.
