Modify boost.build jamfile to support C ++ 11?

Question

I use boost.build or b2 to create a project. I am trying to add C ++ 11, like auto and begin , but the standard invokation b2 release in the Jamfile directory does not recognize them.

Answer 1

The following is added to Jamroot

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

Seems to work

Answer 2

You need to tell the compiler to enable C ++ 11 support

For example, for gcc you can use

 bjam toolset=gcc cxxflags="-std=c++11"
