- Hacking vlc
- ===========
- First
- -----
- - Read this file
- - Read the information present on http://www.videolan.org/developers/
- Requirements
- ____________
- You will need the following tools if you plan to use the GIT version of vlc:
- - Autoconf version 2.60 or later
- - Automake version 1.9 or later
- - gettext version 0.16.1 or later
- - pkg-config
- - libgcrypt 1.2 (or compatible)
- After retrieving the GIT tree, you need to run the bootstrap script to
- generate all the files needed to build vlc. You can then run configure.
- Run ./configure --help for a description of the available options.
- If you do not have the correct version of these tools, or if they are
- simply not available for the operating system you plan to develop on,
- you can check out a GIT tree on an OS that provides these tools (such
- as a recent Linux distribution), run bootstrap, and then copy the whole
- tree to your retarded OS.
- There is a possibility that, at some point, automake might segfault. The
- reason is unsufficient stack size, and can be easily fixed with the
- `ulimit` command (or an equivalent) available in most shells. For instance
- on bash 2.0, the following command solves the automake crash on Mac OS X :
- ulimit -s 20000
- The bootstrap sequence
- ----------------------
- The bootstrap script does the following actions:
- - parse configure.ac for all Makefiles in the modules/ directory that need
- to be generated, and look for available modules in the corresponding
- Modules.am file. A module "foo" exists if there is a Modules.am file in
- the modules/ directory which defines SOURCES_foo.
- - create an m4/private.m4 from configure.ac, generating m4 macros that will
- be needed by configure.ac.
- - create a Makefile.am file for each Modules.am file found in modules/ .
- - run autopoint (previously gettextize) to provide build system support
- for internationalization.
- - run the usual aclocal, autoheader, automake and autoconf, which create
- the various Makefile.in files from the corresponding Makefile.am and the
- configure script from configure.ac.
- - fix a few files in the vlc repository that may have been altered.
- How to add a module
- -------------------
- To add a module to the repository, just add its sources to a Modules.am
- file. If you add a new directory you will need to create a new Modules.am,
- inside that directory. Do not forget to add a corresponding
- Makefile line at the end of configure.ac for this new Modules.am file.
- To have the module built, you need to add a call to VLC_ADD_PLUGIN or
- VLC_ADD_BUILTINS to configure.ac with your new module name as argument.
- Look at other modules for guidelines on how to add build and linkage options.
- After changing configure.ac you will always need to rerun bootstrap and
- configure.
- VLC keeps a cache of its modules (in ~/.cache/vlc/ on Linux), so you'll have to
- delete it (or use vlc --reset-plugins-cache). Then use vlc -vvv --color --list
- to check that your plugin is seen by VLC.
