.. _pkg_toolchain:

Basic toolchain
---------------

A functional compiler, assembler and linker are required to build C++
code.  The C++ compiler must support the C++11 standard at a minimum,
with selected C++14 features such as make_unique.  Optional C++14
features will be enabled if the compiler supports them, otherwise Boost
will be used to provide equivalent functionality.
