Hi Vladimir, It appears to be a bug with the Intel compiler. Along the lines you suggested, here is an example. Note that it needs the using namespace std and the 3.14f (explicitly f and not default or d) to appear. The Intel team is aware of the problem. Thanks b. /tmp> cat test.cc #include <iostream> #include <cmath> using namespace std; int main() { std::cout << isfinite(3.14f) << std::endl; return 0; } /tmp> icpc test.cc /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<std::__is_arithmetic<_Tp>::__value, int>::__type std::isfinite(_Tp) [with _Tp=float]" at line 7 of "test.cc" compilation aborted for test.cc (code 2) /tmp> icpc --version icpc (ICC) 11.1 20090630 Copyright (C) 1985-2009 Intel Corporation.

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?
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)); ^
It appears to be some misconfiguration of the intel compiler. If you create a source file containing just:
#include <cmath>
and try to compile it with icpc, does it work? If not, you probably have to ask Intel support what's going on.
