Hacking vlc
|
|
===========
|
|
|
|
Requirements
|
|
------------
|
|
|
|
You will need the following tools if you plan to use the CVS version of vlc:
|
|
|
|
- autoconf version 2.50 or later
|
|
|
|
- automake version 1.5 (but 1.6 or later is recommended)
|
|
|
|
- gettext version 0.10.40 (but 0.11.3 or later is recommended)
|
|
|
|
After retrieving the CVS tree, you need to run the bootstrap script to
|
|
generate all the files needed to build vlc. You can then run configure.
|
|
|
|
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 CVS 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:
|
|
|
|
- browse the modules/ directory for all available modules. A module "foo"
|
|
exists if there is a Modules.am file in the modules/ directory which
|
|
defines SOURCES_foo.
|
|
|
|
- create a top-level Modules.am file (which will be included by Makefile.am)
|
|
which contains additional build rules for modules, and includes all the
|
|
Modules.am files that were found in modules/
|
|
|
|
- create an m4/vlc.m4 from configure.ac, generating the AC_SUBST and
|
|
AM_CONDITIONAL rules that will be needed by configure.ac.
|
|
|
|
- run autopoint (previously gettextize) to create an intl/ directory,
|
|
needed when libgettext is not available.
|
|
|
|
- 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 create a new Modules.am, do not forget to add a corresponding
|
|
line to modules/Makefile.am.
