Change boost.build jamfile for C++11 support?

Question

I have been using boost.build or b2 for building a project. I am trying to add C++11 contructs like auto and begin but the standard invokation b2 release in the directory with the Jamfile does not recognize these.

Answer 1

Added the following in Jamroot

 <toolset>gcc:<cxxflags>-std=gnu++0x
 <toolset>clang:<cxxflags>-std=c++11

Seems to be working
