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.

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

For example, for gcc you can use

b2 toolset=gcc cxxflags="-std=c++11"

(or the same command with bjam instead of b2; they are identical these days with the bjam kept for backwards-compatibility.)

I was wondering how to change the Jamroot or site config / user config for this – Humble Debugger Aug 28 '13 at 11:16

using gcc : c++11 : "g++" : -std=c++11 ; – Jason Aug 28 '13 at 13:05

Why would I call`bjam` rather than `b2`? Or rather, what's the significance of doing that? – einpoklum Jan 08 '17 at 23:29

@einpoklum for any recent releases of boost they are identical. A duplicate executable named `bjam` is included for backward compatibility – Antoine Dahan Aug 03 '18 at 05:54

Added the following in Jamroot

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

Seems to be working
