Is where any C++ compiler that supports C++0x features already?
Both the 2008 Visual C++ 'Feature Pack' and g++ support some features.
The list of C++0x features supported by g++.
The Visual C++ 2008 Feature Pack ... includes an implementation of TR1. Portions of TR1 are scheduled for adoption in the upcoming C++0x standard as the first major addition to the ISO 2003 standard C++ library. Our implementation includes a number of important features such as:
- Smart pointers
- Regular expression parsing
- New containers (tuple, array, unordered set, etc)
- Sophisticated random number generators
- Polymorphic function wrappers
- Type traits
- And more!
There are compilers that partially support C++0x, but there can't be full support yet because the final C++0x has not yet been standardized.
- GCC 4.4 (not released yet) would support some features like auto.
- GCC 4.3 has not bad tr1 support and some feature like Variadic templates.
- Latest Intel compiler supports quite well some C++0x features: it already has support of auto and lambda function.
Microsoft's Visual Studio 2010 CTP (Community Technology Preview) contains support for four C++0x features namely lambdas, auto, static_assert, and rvalue references.
