Could you share the log of the error you get running make launch, please?

Building B2 engine..

A C++11 capable compiler is required for building the B2 engine.
Toolset 'clang' does not appear to support C++11.

clang++ -x c++ -std=c++11 check_cxx11.cpp
check_cxx11.cpp:14:10: fatal error: 'thread' file not found
#include
^~~~~~~~
1 error generated.

** Note, the C++11 capable compiler is only required for building the B2
** engine. The B2 build system allows for using any C++ level and any other
** supported language and resource in your projects.

You can specify the toolset as the argument, i.e.:
./build.sh [options] gcc

Toolsets supported by this script are:
acc, clang, como, gcc, intel-darwin, intel-linux, kcc, kylix, mipspro,
pathscale, pgi, qcc, sun, sunpro, tru64cxx, vacpp

For any toolset you can override the path to the compiler with the '--cxx'
option. You can also use additional flags for the compiler with the
'--cxxflags' option.

A special toolset; cxx, is available which is used as a fallback when a more
specific toolset is not found and the cxx command is detected. The 'cxx'
toolset will use the '--cxx' and '--cxxflags' options, if present.

Options:
--help Show this help message.
--verbose Show messages about what this script is doing.
--debug Build b2 with debug information, and no
optimizations.
--guess-toolset Print the toolset we can detect for building.
--cxx=CXX The compiler exec to use instead of the detected
compiler exec.
--cxxflags=CXXFLAGS The compiler flags to use in addition to the
flags for the detected compiler.

Do you have g++ installed?

g++ is requiered for boost b2 build, probably this is why your build is failing.

Hi I got the same error with g++ installed, have you solved this issue?
