Control of the processing is based on advanced algorithms that must +run on a programmable processor.

Blurring the boundary between camera devices and +Linux often left the user with no other option than a vendor-specific +closed-source solution. + +To address this problem the Linux media community has very recently started +collaboration with the industry to develop a camera stack that will be +open-source-friendly while still protecting vendor core IP. libcamera was born +out of that collaboration and will offer modern camera support to Linux-based +systems, including traditional Linux distributions, ChromeOS and Android. + + +.. toctree:: + :maxdepth: 2 + :caption: Contents: + + hacking + + + +Indices and tables +================== + +* :ref:`genindex` +* :ref:`search` diff --git a/Documentation/meson.build b/Documentation/meson.build new file mode 100644 index 000000000000..5ab04479d3fb --- /dev/null +++ b/Documentation/meson.build @@ -0,0 +1,20 @@ +sphinx = find_program('sphinx-build-3', required: false) +if not sphinx.found() + sphinx = find_program('sphinx-build', required: false) +endif + +if sphinx.found() + docs_sources = [ + 'hacking.rst', + 'index.rst', + ] + + custom_target('en user documentation', + command: [sphinx, '-W', '-b', 'html', meson.current_source_dir(), '@OUTPUT@'], + input: docs_sources, + output: 'en', + build_by_default: true) + + install_subdir(meson.current_build_dir() + '/en', + install_dir: 'share/doc/libcamera-@0@/user'.format(api_version)) +endif diff --git a/meson.build b/meson.build index 4b3d528c8932..434aa557b8a1 100644 --- a/meson.build +++ b/meson.build @@ -2,8 +2,14 @@ project('libcamera - supporting complex camera pipelines', 'c', 'cpp', version : '0.1', license : 'LGPL 2.1+') +# TODO: Extract this from project.version. +# Ideally the version at Documentation/conf.py should be +# generated from this too. +api_version = '0.1' + inc = include_directories('include') +subdir('Documentation') subdir('lib') subdir('test') subdir('utils')
