How to build Boost with C++0x support?

Question

I have found the answer. I was waiting for a features something like ‘std’ and call it as follows:

bjam std=0x

but currently we need to use the low level variables cxxflags and add the specific compiler flags. For example for gcc we can do

bjam toolset=gcc cxxflags=-std=gnu++0x

Other compilers will need a different setting.

Waiting for a new Boost.Build feature, you can also define your own toolset as follows: Add the user.config or site.config file

using gcc
   : std0x
   : "/usr/bin/g++" # your path to the C++0x compiler
   : <cxxflags>-std=gnu++0x
   ;

And now call as

bjam toolset=gcc-std0x
