After klayge introduced the C ++ 11 feature for the first time, I investigated the support of a mainstream compiler for C ++ 11, to add more C ++ 11 elements in the next version. Here, we also list the alternatives that can be used when they are not supported. Mainly refer to C ++ 11 features in Visual C ++ 11, status of experimental C ++ 0x support in GCC 4.6, status of experimental C ++ 0x support in GCC 4.7, boost.

Here, the "yes" in italic indicates that both VC 11 and GCC 4.7 are supported, and there are non-C ++ 11 alternatives, so it is likely to be used in the next version of klayge. From the table above, we can see that the support for libraries is quite good. Even if the compiler does not support it, it can be easily replaced with boost. The language core is far from perfect, but the most common basics have been covered. Some feature, such as foreach and auto, are supported by boost at the library level, which has a great impact on the Compilation speed. C ++ 11 should greatly improve the compilation performance if it is supported at the core language level.
