Building from source
====================

First thing, clone git repository for yourself (if you haven't done it already),
see :ref:`git repo setup`.

You're going to need the following tools to get started:

* gcc or clang
* meson
* ninja
* pkg-config
* sphinx-build*

| \* optional, to build man-pages and html documentation

And the following dependencies:

* cmocka [#b1]_
* linux-headers [#b2]_
* libpci [#b2]_
* libusb1 [#b2]_
* libftdi1 [#b2]_
* libjaylink [#b2]_
* NI-845x driver & library package [#b3]_
* libcrypto [#b4]_

.. [#b1] | optional, for building unit testing
.. [#b2] | optional, depending on the selected programmer
.. [#b3] | optional, proprietary and Windows only. (See Windows build instructions)
.. [#b4] | optional, to enable RPMC commands

If you are cross compiling, install the dependencies for your target.

TL;DR
-----
::

    meson setup builddir
    meson compile -C builddir
    meson test -C builddir
    meson install -C builddir

Installing dependencies
-----------------------

.. todo:: Move the bullet points to `tabs <https://www.w3schools.com/howto/howto_js_tabs.asp>`_

    * No external dependencies (documentation should be build without fetching all of pypi)
    * No Javascript?

* MSYS2

  Install `MSYS2 <https://www.msys2.org/>`_ and ensure it is `fully updated <https://www.msys2.org/docs/updating/>`_.

  * ``libpci`` is not available through the package manager and pci based programmer are not supported on Windows.
  * ``ni845x_spi`` is only available with the proprietary library from National Instruments. Download and install the driver
    from `ni.com <https://www.ni.com/en-us/support/downloads/drivers/download.ni-845x-driver-software.html>`_ and build flashrom
    for **32-bit**. Add ``-Dprogrammer=ni845x_spi`` to your meson configuration.

  In the MSYS2 UCRT64 shell run::

      pacman -Sy \
      mingw-w64-ucrt-x86_64-gcc mingw-w64-ucrt-x86_64-meson mingw-w64-ucrt-x86_64-ninja mingw-w64-ucrt-x86_64-pkg-config mingw-w64-ucrt-x86_64-python-sphinx \

  For building flashrom as 32-bit application, use the MSYS2 MINGW32 shell and run::

      pacman -Sy \

DJGPP-DOS

* Get `DJGPP <https://www.delorie.com/djgpp/>`_
* A great build script can be found `here <https://github.com/andrewwutw/build-djgpp>`_

| Run the following commands in the the pciutils directory to build libpci for DOS.

    export PKG_CONFIG_SYSROOT=<DOS_INSTALL_ROOT>

* To compile flashrom use the ``meson_cross/i586_djgpp_dos.txt`` cross-file
* You will need `CWSDPMI.EXE <https://sandmann.dotster.com/cwsdpmi/>`_ to run flashrom

libpayload
""""""""""

    .. todo:: Add building instructions for libpayload


.. _meson_configuration:

Configuration
-------------

In the flashrom repository run::

    meson setup [builtin options] [flashrom options] <builddir>

Mesons ``[builtin options]`` can be displayed with ``meson setup --help``.
The flashrom specific options can be found in ``meson_options.txt`` in the top-level
directory of flashrom and are used like in cmake with ``-Doption=value``
Run ``meson configure`` to display all configuration options.

.. todo:: Write a sphinx extension to render ``meson_options.txt`` here


Configuration for Crossbuilds
-----------------------------
Flashrom specific cross-files can be found in the ``meson_cross`` folder.
To use them run::

    meson setup --cross-file <path/to/crossfile> [builtin options] [flashrom options] <builddir>

The options are the same as the normal configuration options. For more information see
https://mesonbuild.com/Cross-compilation.html


Compiling
---------
Run::

    meson compile -C <builddir>


Update configuration
--------------------
If you want to change your initial configuration for some reason
(for example you discovered that a programmer is missing), run::

    meson configure [updated builtin options] [updated flashrom options] <builddir>

.. _unit tests:

Unit Tests
----------
To execute the unit tests run::

    meson test -C <builddir>

You will get a summary of the unit test results at the end.


Code coverage
"""""""""""""
gcov
    Due to a bug in lcov, the html file will only be correct if lcov is not
    installed and gcovr is installed. See
    https://github.com/linux-test-project/lcov/issues/168 and
    https://github.com/mesonbuild/meson/issues/6747

    To create the coverage target add ``-Db_coverage=true`` to your build configuration.
    After executing the tests, you can run ::

        ninja -C <builddir> coverage

    to generate the coverage report.

lcov / llvm
    https://clang.llvm.org/docs/SourceBasedCodeCoverage.html
    Make sure that you are using `clang` as compiler, e.g. by setting `CC=clang` during configuration.
    Beside that you need to add ``-Dllvm_cov=enabled`` to your build configuration ::

        CC=clang meson setup -Dllvm_cov=enable <builddir>
        meson test -C <builddir>
        ninja -C <builddir> llvm-cov-tests

For additional information see `the meson documentation <https://mesonbuild.com/Unit-tests.html#coverage>`_


Installing
----------
To install flashrom and documentation, run::

    meson install -C <builddir>

This will install flashrom under the PREFIX selected in the configuration phase. Default is ``/usr/local``.

To install into a different directory use DESTDIR, like this::

	DESTDIR=/your/destination/directory meson install -C <your_build_dir>

You can also set the prefix during configuration with::

	meson setup --prefix <DESTDIR> <your_build_dir>

Create distribution package
---------------------------
To create a distribution tarball from your ``builddir``, run::

    meson dist -C <builddir>

This will collect all git tracked files and pack them into an archive.

Current flashrom version is in the VERSION file. To release a new flashrom
version you need to change VERSION file and tag the changing commit.
