These build instructions are mostly based on `Documentation/building.md` and the wiki. There are some `.. todo::` sections still present in the documentation. They will be completed later. For some of the todos content needs to be written, some others require custom sphinx-plugins to be implemented. The `.. todo::` sections are only visible in the source, not in the rendered html.

Building from source
|
|
====================
|
|
|
|
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*
|
|
* linux-headers**
|
|
* libpci**
|
|
* libusb1**
|
|
* libftdi1**
|
|
* libjaylink**
|
|
|
|
| \* optional, for building unit testing
|
|
| \** optional, depending on the selected programmer
|
|
|
|
If you are cross compiling, install the dependencies for your target.

|
|
|
|
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
|
|
----------
|
|
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
|
|
----------
|
|
Run::
|
|
|
|
meson install -C <builddir>
|
|
|
|
This will install flashrom under the PREFIX selected in the configuration phase. Default is ``/usr/local``.
|
|
|
|
|
|
Create distribution package
|
|
---------------------------
|
|
To create a distribution tarball from your <builddir>, run::
|
|
|
|
meson dist -C <builddir>
|
