This is MacOSX 10.6.8 running various compilers provided by MacPorts.
Compiling the following C++ source
double d = std::log2(2.3456789f);
'log2' is not a member of 'std'.
This happens with the system g++, which is i686-apple-darwin10-g++-4.2.1,
each of g++-4.0 g++-4.2 g++-mp-5 g++-mp-6, and with clang++-mp-3.4;
in each case, I am compiling as $CXX -std=c++11 prog.c
Apparently, there is some relatively recent turmoil about the C++ libs;
I don't know much c++ but find myself compiling some third party C++ code.
Am I missing something obvious?
