Build and Installation
|
|
|
|
Our build system is based on autotools. For preparing the build of a SVN
|
|
snapshot you will need autotools of at least version 1.7.
|
|
Check out from SVN by
|
|
svn co http://svn.libburnia-project.org/libburn/trunk libburn
|
|
go into directory libburn and apply autotools by
|
|
./bootstrap
|
|
|
|
Alternatively you may unpack a release tarball for which you do not need
|
|
autotools installed.
|
|
|
|
To build a libburnia-project.org subproject it should be sufficient to go
|
|
into its toplevel directory (here: "libburn") and execute
|
|
./configure --prefix=/usr
|
|
make
|
|
|
|
To make libburn accessible for running resp. application development,
|
|
and to install the cdrecord compatibility binary cdrskin, do:
|
|
make install
|
|
|
|
|
|
Above procedure installs cdrskin depending on libburn.so.4 .
|
|
For a standalone cdrskin binary, see cdrskin/README.
|
|
|
|
|
|
An important part of the project, libisofs, is hosted in a bzr repository at
|
|
launchpad.net :
|
|
bzr branch lp:libisofs
|
|
|
|
Another part the project, libisoburn, is hosted in the libburnia SVN, too:
|
|
svn co http://svn.libburnia-project.org/libisoburn/trunk libisoburn
|
|
|
|
See README files there.

|
|
Overview of libburnia-project.org
|
|
|
|
libburnia-project.org is an open-source software project for reading, mastering
|
|
and writing optical discs.
|
|
For now this means only CD media and all single layer DVD media except DVD+R.
|
|
|
|
The project comprises of several more or less interdependent parts which
|
|
together strive to be a usable foundation for application development.
|
|
These are libraries, language bindings, and middleware binaries which emulate
|
|
classical (and valuable) Linux tools.
|
|
|
|
Our scope is currently Linux 2.4 and 2.6 only. For ports to other systems
|
|
we would need : login on a development machine resp. a live OS on CD or DVD,
|
|
advise from a system person about the equivalent of Linux sg or FreeBSD CAM,
|
|
volunteers for testing of realistic use cases.
|
|
|
|
We have a well tested code base for burning data and audio CDs and many DVD
|
|
types. The burn API is quite comprehensively documented and can be used to
|
|
build a presentable application.
|
|
We have a functional binary which emulates the core use cases of cdrecord in
|
|
order to prove that usability, and in order to allow you to explore libburn's
|
|
scope by help of existing cdrecord frontends.
|
|
|
|
ISO 9660 filesystems with Rock Ridge and Joliet extensions can be created
|
|
and manipulated quite freely. This capability together with our burn capability
|
|
makes possible a single binary application which covers all steps of image
|
|
composition, updating and writing. Quite unique in the Linux world.
|
|
|
|
The project components (list subject to growth, hopefully):
|
|
|
|
- libburn is the library by which preformatted data get onto optical media.
|
|
It uses either /dev/sgN (e.g. on kernel 2.4 with ide-scsi) or
|
|
/dev/srM or /dev/hdX (e.g. on kernel 2.6).
|
|
libburn is the foundation of our cdrecord emulation. Its code is
|
|
independent of cdrecord. Its DVD capabilities are learned from
|
|
studying the code of dvd+rw-tools and MMC-5 specs. No code but only
|
|
the pure SCSI knowledge has been taken from dvd+rw-tools, though.
|
|
|
|
- libisofs is the library to pack up hard disk files and directories into a
|
|
ISO 9660 disk image. This may then be brought to CD via libburn.
|
|
libisofs is to be the foundation of our upcoming mkisofs emulation.
|
|
|
|
- libisoburn is an add-on to libburn and libisofs which coordinates both and
|
|
also allows to grow ISO-9660 filesystem images on multi-session
|
|
media as well as on overwriteable media via the same API.
|
|
All media peculiarities are handled automatically.
|
|
|
|
- cdrskin is a limited cdrecord compatibility wrapper for libburn.
|
|
cdrecord is a powerful GPL'ed burn program included in Joerg
|
|
Schilling's cdrtools. cdrskin strives to be a second source for
|
|
the services traditionally provided by cdrecord. Additionally it
|
|
provides libburn's DVD capabilities, where only -sao is compatible
|
|
with cdrecord.
|
|
cdrskin does not contain any bytes copied from cdrecord's sources.
|
|
Many bytes have been copied from the message output of cdrecord
|
|
runs, though.
|
|
See cdrskin/README for more.
|
|
|
|
- xorriso is an application of all three libraries which creates, loads,
|
|
manipulates and writes ISO 9660 filesystem images with
|
|
Rock Ridge extensions. Manipulation is not only adding or
|
|
overwriting of files but also deletion, renaming, and attribute
|
|
changing.
|
|
See xorriso/README for more.
|
|
|
|
- "test" is a collection of application gestures and examples given by the
|
|
authors of the library features. The burn API example of libburn
|
|
is named test/libburner.c . The API for media information inquiry is
|
|
demonstrated in test/telltoc.c .
|
|
Explore these examples if you look for inspiration.
|
|
|
|
We strive to be a responsive upstream.
|
|
|
|
Our libraries are committed to maintain older feature sets in newer versions.
|
|
This applies to source code headers (API) as well as to linkable objects (ABI).
|
|
The only exception from this rule is about non-release versions x.y.*[13579]
|
|
which are allowed to introduce new features, change those new features in
|
|
any way and even may revoke such new features before the next release of
|
|
x.y.*[02468]. As soon as it is released, a feature is promised to persist.
|
|
|
|
SONAMES:
|
|
libburn.so.4 (since 0.3.4, March 2007),
|
|
libisofs.so.6 (since 0.6.2, February 2008),
|
|
libisoburn.so.1 (since 0.1.0, February 2008).

|
|
Project history as far as known to me:
|
|
|
|
- Founded in 2002 as it seems. See mailing list archives
|
|
http://lists.freedesktop.org/archives/libburn/
|
|
The site of this founder team is reachable and offers download of a
|
|
(somewhat outdated) tarball and from CVS :
|
|
http://icculus.org/burn/
|
|
Copyright holders and most probably founders:
|
|
Derek Foreman and Ben Jansens.
|
|
|
|
- I came to using libburn in 2005. Founded the cdrskin project and submitted
|
|
necessary patches which were accepted or implemented better. Except one
|
|
remaining patch which prevented cdrskin from using vanilla libburn from CVS.
|
|
The cdrskin project site is reachable and offers download of the heavily
|
|
patched (elsewise outdated) tarball under the name cdrskin-0.1.2 :
|
|
http://scdbackup.sourceforge.net/cdrskin_eng.html
|
|
It has meanwhile moved to use vanilla libburn.pykix.org , though.
|
|
Version 0.1.4 constitutes the first release of this kind.
|
|
|
|
- In July 2006 our team mate Mario Danic announced a revival of libburn
|
|
which by about nearly everybody else was perceived as unfriendly fork.
|
|
Derek Foreman four days later posted a message which expressed his
|
|
discontent.
|
|
The situation first caused me to publically regret it and then - after i
|
|
got the opportunity to move in with cdrskin - gave me true reason to
|
|
personally apologize to Derek Foreman, Ben Jansens and the contibutors at
|
|
icculus.org/burn. Posted to both projects:
|
|
http://lists.freedesktop.org/archives/libburn/2006-August/000446.html
|
|
http://mailman-mail1.webfaction.com/pipermail/libburn-hackers/2006-August/000024.html
|
|
|
|
- Mid August 2006 project cdrskin established a branch office in
|
|
libburn.pykix.org so that all maintainers of our tools have one single place
|
|
to get the current (at least slightely) usable coordinated versions of
|
|
everything.
|
|
Project cdrskin will live forth independendly for a while but it is committed
|
|
to stay in sync with libburn.pykix.org (or some successor, if ever).
|
|
cdrskin is also committed to support icculus.org/burn if the pending fork
|
|
is made reality by content changes in that project. It will cease to maintain
|
|
a patched version of icculus.org/burn though. Precondition for a new
|
|
release of cdrskin on base of icculus.org/burn would be the pending
|
|
"whitelist patch" therefore.
|
|
I would rather prefer if both projects find consense and merge, or at least
|
|
cooperate. I have not given up hope totally, yet.
|
|
I, personally, will honor any approach.
|
|
|
|
- 2nd September 2006 the decision is made to strive for a consolidation of
|
|
copyright and a commitment to GPL in a reasonable and open minded way.
|
|
This is to avoid long term problems with code of unknown origin and
|
|
with finding consense among the not so clearly defined group of copyright
|
|
claimers and -holders.
|
|
libisofs is already claimed sole copyright Mario Danic.
|
|
cdrskin and libburner are already claimed sole copyright Thomas Schmitt.
|
|
Rewrites of other components will follow and concluded by claiming full
|
|
copyright within the group of libburn.pykix.org-copyright holders.
|
|
|
|
- 16th September 2006 feature freeze for release of libburn-0.2.2 .
|
|
|
|
- 20th September 2006 release of libburn-0.2.2 .
|
|
|
|
- 26th October 2006 feature freeze for cdrskin-0.2.4 based on libburn-0.2.3 .
|
|
This version of cdrskin is much more cdrecord compatible in repect
|
|
to drive addressing and audio features.
|
|
|
|
- 30th October 2006 release of cdrskin-0.2.4 .
|
|
|
|
- 13th November 2006 splitting releases of libburn+cdrskin from libisofs.
|
|
|
|
- 24th November 2006 release of libburn-0.2.6 and cdrskin-0.2.6 . cdrskin has
|
|
become suitable for unaware frontends as long as they perform only the core
|
|
of cdrecord use cases (including open-ended input streams, audio, and
|
|
multi-session).
|
|
|
|
- 28th November 2006 the umbrella project which encloses both, libisofs and
|
|
libburn, is now called libburnia. For the origin of this name, see
|
|
http://en.wikipedia.org/wiki/Liburnians .
|
|
|
|
- 16th January 2007 release of libburn-0.3.0 and cdrskin-0.3.0 . Now the scope
|
|
is widened to a first class of DVD media: overwriteable single layer types
|
|
DVD-RAM, DVD+RW, DVD-RW. This is not a cdrecord emulation but rather inspired
|
|
by dvd+rw-tools' "poor man" writing facility for this class of media.
|
|
Taking a bow towards Andy Polyakov.
|
|
|
|
- 11th February 2007 version 0.3.2 covers sequential DVD-RW and DVD-R with
|
|
multi-session and with DAO.
|
|
|
|
- 12th March 2007 version 0.3.4 supports DVD+R and thus covers all single layer
|
|
DVD media. Code for double layer DVD+/-R is implemented but awaits a tester
|
|
yet.
|
|
|
|
- 23th April 2007 version 0.3.6 follows the unanimous opinion of Linux kernel
|
|
people that one should not use /dev/sg on kernel 2.6.
|
|
|
|
- 31st July 2007 version 0.3.8 marks the first anniversary of libburn revival.
|
|
We look back on improved stability, a substantially extended list of media
|
|
and write modes, and better protection against typical user mishaps.
|
|
|
|
- 24th October 2007 version 0.4.0 is the foundation of new library libisoburn
|
|
and an upcomming integrated application for manipulating and writing
|
|
ISO 9660 + Rock Ridge images. cdrskin-0.4.0 got capabilities like growisofs
|
|
by these enhancements: growing of overwriteable media and disk files.
|
|
Taking again a bow towards Andy Polyakov.
|
|
|
|
- 26th Januar 2008 version 0.4.2 rectifies the version numbering so that we
|
|
reliably release libburn.so.4 as should have been done since libburn-0.3.2.
|
|
cdrskin now is by default linked dynamically and does a runtime check
|
|
to ensure not to be started with a libburn which is older than itself.
|
|
|
|
- 3rd Feb 2008 libisofs-0.2.x (.so.5) has been deprecated.
|
|
|
|
- 14th Feb 2008 libisofs-0.6.2 permanently replaces the old libisofs-0.2.x.
|
|
It is the first release of new libisofs.so.6 which will guarantee future
|
|
API/ABI compatibility for its whole feature set.
|
|
|
|
- 15th Feb 2008 libisoburn-0.1.0 (.so.1) coordinates libisofs and libburn for
|
|
the purpose of ISO image reading and writing. It emulates multi-session on
|
|
overwriteable media. Application xorriso makes use of all three libraries.
|
|
|
|
- 8th Apr 2008 libburn-0.4.4 has proven to be capable of burning to DVD+R/DL
|
|
and read performance on disk file pseudo-drives has been improved.
|
|
|
|
- 27th Apr 2008 libisofs-0.6.4 can now read data file content from images
|
|
and can map pieces of disk files onto image files. Image directory iteration
|
|
has been enhanced. Input data streams and extended information have been
|
|
exposed in the API to allow future development.
|
|
|
|
- 29th Apr 2008 libisoburn-0.1.4 was made more efficient with reading of
|
|
image tree nodes. It now depends on libisofs-0.6.4 and libburn-0.4.4.
|
|
xorriso makes use of new libisofs features by performing incremental
|
|
updates of directory trees and by cutting oversized data files into
|
|
pieces. A primitive single session emulation of cdrcord and mkisofs is
|
|
provided.
|
|
|
|
- 10th May 2008 libburn-0.4.6 supports formatting and writing of BD-RE,
|
|
full nominal speed for DVD-RAM and BD-RE. cdrskin has a unified blank
|
|
type with automatic media state recognition.

|
Clarification in my name and in the name of Mario Danic, upcoming copyright
|
|
holders on toplevel of libburnia. To be fully in effect after the remaining
|
|
other copyrighted code has been replaced by ours and by copyright-free
|
|
contributions of our friends:
|
|
------------------------------------------------------------------------------
|
|
|
|
We, the copyright holders, agree on the interpretation that
|
|
dynamical linking of our libraries constitutes "use of" and
|
|
not "derivation from" our work in the sense of GPL, provided
|
|
those libraries are compiled from our unaltered code.
|
|
|
|
Thus you may link our libraries dynamically with applications
|
|
which are not under GPL. You may distribute our libraries and
|
|
application tools in binary form, if you fulfill the usual
|
|
condition of GPL to offer a copy of the source code -altered
|
|
or unaltered- under GPL.
|
|
|
|
We ask you politely to use our work in open source spirit
|
|
and with the due reference to the entire open source community.
|
|
|
|
If there should really arise the case where above clarification
|
|
does not suffice to fulfill a clear and neat request in open source
|
|
spirit that would otherwise be declined for mere formal reasons,
|
|
only in that case we will duely consider to issue a special license
|
|
covering only that special case.
|
|
It is the open source idea of responsible freedom which will be
|
|
decisive and you will have to prove that you exhausted all own
|
|
means to qualify for GPL.
|
|
|
|
For now we are firmly committed to maintain one single license: GPL.
