.. _BUILD:mcode:
mcode backend
#############
The mcode backend is available for all supported platforms and is also the
simplest procedure, because it requires the fewest dependencies and configuration
options.
.. _BUILD:mcode:GNAT:
GCC/GNAT: GNU/Linux or Windows (MinGW/MSYS2)
============================================
.. rubric:: Requirements
* GCC (Gnu Compiler Collection)
* GNAT (Ada compiler for GCC)
GHDL is configured by ``configure`` and built by ``make``.
* First, GHDL needs to be configured. It is common to specify a ``PREFIX``
(installation directory like ``/usr/local`` or ``/opt/ghdl``). Without any
other option, ``configure`` selects `mcode` as the backend.
* Next, ``make`` starts the compilation process.
* Finally, ``make install`` installs GHDL into the installation directory
specified by ``PREFIX``.
.. HINT :: ON GNU/Linux, you may need super user privileges (``sudo ...``).
.. rubric:: Example:
.. code-block:: Bash
$ cd <ghdl>
$ mkdir build
$ cd build
$ ../configure --prefix=PREFIX
$ make
$ make install
