  14. ------------------------------------------------------------------------------
  15. Build and Installation
  16. From tarball
  17. Obtain libburn-1.5.2.pl01.tar.gz, take it to a directory of your choice and do:
  18. tar xzf libburn-1.5.2.pl01.tar.gz
  19. cd libburn-1.5.2
  20. ./configure --prefix=/usr
  21. make
  22. To make libburn accessible for running and application development,
  23. and to install the cdrecord compatibility binary cdrskin, do
  24. (as Superuser):
  25. make install
  26. This procedure installs libburn.so.4 and cdrskin depending on it.
  27. For a standalone cdrskin binary, see cdrskin/README.
  28. A behavioral conflict is known between any burn software and demons like hald
  29. which probe CD drives. This can spoil burn runs for CD-R or CD-RW.
  30. You may have to keep your hald away from the drive. See for example
  31. http://www.freebsd.org/gnome/docs/halfaq.html
  32. From SVN
  33. Our build system is based on autotools. For preparing the build of a SVN
  34. snapshot you will need autotools of at least version 1.7.
  35. Do in a directory of your choice:
  36. svn co http://svn.libburnia-project.org/libburn/trunk libburn-svn
  37. cd libburn-svn
  38. ./bootstrap
  39. ./configure --prefix=/usr
  40. make
  41. make install
  42. Warning: The trunk might contain experimental features which might not
  43. persist until next release.
  44. Special ./configure options
  45. make install on GNU/Linux will try to run program ldconfig with the library
  46. installation directory as only argument. Failure to do so will not abort
  47. installation. One may disable ldconfig by ./configure option:
  48. --disable-ldconfig-at-install
  49. In some situations Linux may deliver a better write performance to drives if
  50. the track input is read with O_DIRECT (see man 2 open). The API call
  51. burn_os_open_track_src() and the input readers of cdrskin and libburn fifo
  52. can be told to use this peculiar read mode by:
  53. --enable-track-src-odirect
  54. But often libburn call burn_write_opts_set_dvd_obs(opts, 64*1024) will yield
  55. even better performance in such a situation. 64k can be made default at
  56. configure time by:
  57. --enable-dvd-obs-64k
  58. This may be combined with above --enable-track-src-odirect .
  59. If it is desired that DVD DAO writing and stdio: writing get padded up to
  60. a full write chunk of 32k or 64k, then use ./configure option:
  61. --enable-dvd-obs-pad
  62. Alternatively the transport of SCSI commands can be done via libcdio-0.83.
  63. You may install it and re-run libburn's ./configure with option
  64. --enable-libcdio
  65. By use of a version script, the libburn.so library exposes no other function
  66. names but those of the API definition in libburn/libburn.h.
  67. If -Wl,--version-script=... makes problems with the local compiler, then
  68. disable this encapsulation feature by
  69. --disable-versioned-libs
  70. Make sure to re-compile all source files after running ./configure
  71. make clean ; make
  72. make install
  73. Linux only:
  74. libburn tries to avoid a collision with udev's drive examination by waiting
  75. 0.1 seconds before opening the device file for a longer time, after udev
  76. might have been alarmed by drive scanning activities.
  77. The waiting time can be set at ./configure time with microsecond granularity.
  78. E.g. 2 seconds:
  79. CFLAGS="$CFLAGS -DLibburn_udev_wait_useC=2000000"
  80. ./configure ...options...
  81. Waiting can be disabled by zero waiting time:
  82. CFLAGS="$CFLAGS -DLibburn_udev_wait_useC=0"
  83. Alternatively, libburn can try to be nice by opening the device file,
  84. closing it immediately, waiting, and only then opening it for real:
  85. CFLAGS="$CFLAGS -DLibburn_udev_extra_open_cyclE -DLibburn_udev_wait_useC=500000"
  86. ------------------------------------------------------------------------------
  87. An important part of the project, libisofs, is hosted in a bzr repository at
  88. launchpad.net :
  89. bzr branch lp:libisofs
  90. Another part the project, libisoburn, is hosted in the libburnia SVN, too:
  91. svn co http://svn.libburnia-project.org/libisoburn/trunk libisoburn
  92. See README files there.
  93. ------------------------------------------------------------------------------
  94. Overview of libburnia-project.org
  95. libburnia-project.org is an open-source software project for reading, mastering
  96. and writing optical discs.
  97. For now this means CD media, all DVD media, all BD media.
  98. The project comprises of several more or less interdependent parts which
  99. together strive to be a usable foundation for application development.
  100. These are libraries, language bindings, and middleware binaries which emulate
  101. classical (and valuable) Linux tools.
  102. Currently it is supported on GNU/Linux with kernels >= 2.4,
  103. on FreeBSD with ATAPI/CAM enabled in the kernel (see man atapicam),
  104. on OpenSolaris (tested with kernel 5.11),
  105. on NetBSD (tested with 6.1.3).
  106. On other X/Open compliant systems there will only be pseudo drives, but no
  107. direct MMC operation on real CD/DVD/BD drives.
  108. For full ports to other systems we would need : login on a development machine
  109. or a live OS on CD or DVD, advise from a system person about the equivalent
  110. of Linux sg or FreeBSD CAM, volunteers for testing of realistic use cases.
  111. We have a well tested code base for burning data and audio CDs, DVDs and BDs.
  112. The burn API is quite comprehensively documented and can be used to build a
  113. presentable application.
  114. We have a functional application which emulates the core use cases of cdrecord
  115. in order to prove that usability, and in order to allow you to explore
  116. libburn's scope by help of existing cdrecord frontends.
  117. ISO 9660 filesystems with Rock Ridge and Joliet extensions can be created
  118. and manipulated quite freely. This capability together with our burn capability
  119. makes possible a single binary application which covers all steps of image
  120. composition, updating and writing. Quite unique in the Linux world.
  121. The project components (list subject to growth, hopefully):
  122. - libburn is the library by which preformatted data get onto optical media.
  123. It uses either /dev/sgN (e.g. on kernel 2.4 with ide-scsi) or
  124. /dev/srM or /dev/hdX (e.g. on kernel 2.6).
  125. libburn is the foundation of our cdrecord emulation. Its code is
  126. independent of cdrecord. Its DVD capabilities are learned from
  127. studying the code of dvd+rw-tools and MMC-5 specs. No code but only
  128. the pure SCSI knowledge has been taken from dvd+rw-tools, though.
  129. - libisofs is the library to pack up hard disk files and directories into a
  130. ISO 9660 disk image. This may then be brought to CD via libburn.
  131. An own ISO 9660 extension stores ACLs, xattr, and MD5 of file
  132. content.
  133. - libisoburn is an add-on to libburn and libisofs which coordinates both and
  134. also can grow ISO-9660 filesystem images on multi-session media
  135. as well as on overwriteable media via the same API.
  136. All media peculiarities are handled automatically.
  137. It also contains the methods of command oriented application
  138. xorriso and offers them via a C language API.
  139. - cdrskin is a limited cdrecord compatibility wrapper for libburn.
  140. cdrecord is a powerful GPL'ed burn program included in Joerg
  141. Schilling's cdrtools. cdrskin strives to be a second source for
  142. the services traditionally provided by cdrecord. Additionally it
  143. provides libburn's DVD capabilities, where only -sao is compatible
  144. with cdrecord.
  145. cdrskin does not contain any bytes copied from cdrecord's sources.
  146. Many bytes have been copied from the message output of cdrecord
  147. runs, though.
  148. See cdrskin/README for more.
  149. - xorriso is an application of all three libraries which creates, loads,
  150. manipulates and writes ISO 9660 filesystem images with
  151. Rock Ridge extensions. Manipulation is not only adding or
  152. overwriting of files but also deleting, renaming, attribute
  153. changing, incremental backups, activating boot images, and
  154. extracting of files from ISO images to disk. There is also a
  155. sparse emulation of cdrecord and a more laborate one of mkisofs.
  156. All features of xorriso are also available via a C language API
  157. of libisoburn.
  158. A static compilation of xorriso and the libraries is dedicated
  159. to the GNU Operating System. See xorriso/README_gnu_xorriso .
  160. - "test" is a collection of application gestures and examples given by the
  161. authors of the library features. The burn API example of libburn
  162. is named test/libburner.c . The API for media information inquiry is
  163. demonstrated in test/telltoc.c .
  164. Explore these examples if you look for inspiration.
  165. We strive to be a responsive upstream.
  166. Our libraries are committed to maintain older feature sets in newer versions.
  167. This applies to source code headers (API) as well as to linkable objects (ABI).
  168. The only exception from this rule is about non-release versions x.y.*[13579]
  169. which are allowed to introduce new features, change those new features in
  170. any way and even may revoke such new features before the next release of
  171. x.y.*[02468]. As soon as it is released, a feature is promised to persist.
  172. SONAMES:
  173. libburn.so.4 (since 0.3.4, March 2007),
  174. libisofs.so.6 (since 0.6.2, February 2008),
  175. libisoburn.so.1 (since 0.1.0, February 2008).
  176. Applications must use 64 bit off_t. E.g. by defining
  177. #define _LARGEFILE_SOURCE
  178. #define _FILE_OFFSET_BITS 64
  179. or take special precautions to interface with the libraries by 64 bit integers
  180. where the .h files prescribe off_t. To reduce libburn's off_t size to 32 bit
  181. will keep it from processing tracks of more than 2 GB size.
  182. ------------------------------------------------------------------------------
  183. Project history as far as known to me:
  184. - Founded in 2002 as it seems. See mailing list archives
  185. http://lists.freedesktop.org/archives/libburn/
  186. The site of this founder team is reachable and offers download of a
  187. (somewhat outdated) tarball and from CVS :
  188. http://icculus.org/burn/
  189. Copyright holders and most probably founders:
  190. Derek Foreman and Ben Jansens.
  191. - I came to using libburn in 2005. Founded the cdrskin project and submitted
  192. necessary patches which were accepted or implemented better. Except one
  193. remaining patch which prevented cdrskin from using vanilla libburn from CVS.
  194. The cdrskin project site is reachable and offers download of the heavily
  195. patched (elsewise outdated) tarball under the name cdrskin-0.1.2 :
  196. http://scdbackup.sourceforge.net/cdrskin_eng.html
  197. It has meanwhile moved to use vanilla libburn.pykix.org , though.
  198. Version 0.1.4 constitutes the first release of this kind.
  199. - In July 2006 our team mate Mario Danic announced a revival of libburn
  200. which by about nearly everybody else was perceived as unfriendly fork.
  201. Derek Foreman four days later posted a message which expressed his
  202. discontent.
  203. The situation first caused me to publicly regret it and then - after i
  204. got the opportunity to move in with cdrskin - gave me true reason to
  205. personally apologize to Derek Foreman, Ben Jansens and the contributors at
  206. icculus.org/burn. Posted to both projects:
  207. http://lists.freedesktop.org/archives/libburn/2006-August/000446.html
  208. http://mailman-mail1.webfaction.com/pipermail/libburn-hackers/2006-August/000024.html
  209. - Mid August 2006 project cdrskin established a branch office in
  210. libburn.pykix.org so that all maintainers of our tools have one single place
  211. to get the current (at least slightely) usable coordinated versions of
  212. everything.
  213. Project cdrskin will live forth independendly for a while but it is committed
  214. to stay in sync with libburn.pykix.org (or some successor, if ever).
  215. cdrskin is also committed to support icculus.org/burn if the pending fork
  216. is made reality by content changes in that project. It will cease to maintain
  217. a patched version of icculus.org/burn though. Precondition for a new
  218. release of cdrskin on base of icculus.org/burn would be the pending
  219. "whitelist patch" therefore.
  220. I would rather prefer if both projects find consense and merge, or at least
  221. cooperate. I have not given up hope totally, yet.
  222. I, personally, will honor any approach.
  223. - 2nd September 2006 the decision is made to strive for a consolidation of
  224. copyright and a commitment to GPL in a reasonable and open minded way.
  225. This is to avoid long term problems with code of unknown origin and
  226. with finding consense among the not so clearly defined group of copyright
  227. claimers and -holders.
  228. libisofs is already claimed sole copyright Mario Danic.
  229. cdrskin and libburner are already claimed sole copyright Thomas Schmitt.
  230. Rewrites of other components will follow and concluded by claiming full
  231. copyright within the group of libburn.pykix.org-copyright holders.
  232. - 16th September 2006 feature freeze for release of libburn-0.2.2 .
  233. - 20th September 2006 release of libburn-0.2.2 .
  234. - 26th October 2006 feature freeze for cdrskin-0.2.4 based on libburn-0.2.3 .
  235. This version of cdrskin is much more cdrecord compatible in repect
  236. to drive addressing and audio features.
  237. - 30th October 2006 release of cdrskin-0.2.4 .
  238. - 13th November 2006 splitting releases of libburn+cdrskin from libisofs.
  239. - 24th November 2006 release of libburn-0.2.6 and cdrskin-0.2.6 . cdrskin has
  240. become suitable for unaware frontends as long as they perform only the core
  241. of cdrecord use cases (including open-ended input streams, audio, and
  242. multi-session).
  243. - 28th November 2006 the umbrella project which encloses both, libisofs and
  244. libburn, is now called libburnia. For the origin of this name, see
  245. http://en.wikipedia.org/wiki/Liburnians .
  246. - 16th January 2007 release of libburn-0.3.0 and cdrskin-0.3.0 . Now the scope
  247. is widened to a first class of DVD media: overwriteable single layer types
  248. DVD-RAM, DVD+RW, DVD-RW. This is not a cdrecord emulation but rather inspired
  249. by dvd+rw-tools' "poor man" writing facility for this class of media.
  250. Taking a bow towards Andy Polyakov.
  251. - 11th February 2007 version 0.3.2 covers sequential DVD-RW and DVD-R with
  252. multi-session and with DAO.
  253. - 12th March 2007 version 0.3.4 supports DVD+R and thus covers all single layer
  254. DVD media. Code for double layer DVD+/-R is implemented but awaits a tester
  255. yet.
  256. - 23th April 2007 version 0.3.6 follows the unanimous opinion of Linux kernel
  257. people that one should not use /dev/sg on kernel 2.6.
  258. - 31st July 2007 version 0.3.8 marks the first anniversary of libburn revival.
  259. We look back on improved stability, a substantially extended list of media
  260. and write modes, and better protection against typical user mishaps.
  261. - 24th October 2007 version 0.4.0 is the foundation of new library libisoburn
  262. and an upcoming integrated application for manipulating and writing
  263. ISO 9660 + Rock Ridge images. cdrskin-0.4.0 got capabilities like growisofs
  264. by these enhancements: growing of overwriteable media and disk files.
  265. Taking again a bow towards Andy Polyakov.
  266. - 26th Januar 2008 version 0.4.2 rectifies the version numbering so that we
  267. reliably release libburn.so.4 as should have been done since libburn-0.3.2.
  268. cdrskin now is by default linked dynamically and does a runtime check
  269. to ensure not to be started with a libburn which is older than itself.
  270. - 3rd Feb 2008 libisofs-0.2.x (.so.5) has been deprecated.
  271. - 14th Feb 2008 libisofs-0.6.2 permanently replaces the old libisofs-0.2.x.
  272. It is the first release of new libisofs.so.6 which will guarantee future
  273. API/ABI compatibility for its whole feature set.
  274. - 15th Feb 2008 libisoburn-0.1.0 (.so.1) coordinates libisofs and libburn for
  275. the purpose of ISO image reading and writing. It emulates multi-session on
  276. overwriteable media. Application xorriso makes use of all three libraries.
  277. - 8th Apr 2008 libburn-0.4.4 has proven to be capable of burning to DVD+R/DL
  278. and read performance on disk file pseudo-drives has been improved.
  279. - 27th Apr 2008 libisofs-0.6.4 can now read data file content from images
  280. and can map pieces of disk files onto image files. Image directory iteration
  281. has been enhanced. Input data streams and extended information have been
  282. exposed in the API to enable future development.
  283. - 29th Apr 2008 libisoburn-0.1.4 was made more efficient with reading of
  284. image tree nodes. It now depends on libisofs-0.6.4 and libburn-0.4.4.
  285. xorriso makes use of new libisofs features by performing incremental
  286. updates of directory trees and by cutting oversized data files into
  287. pieces. A primitive single session emulation of cdrecord and mkisofs is
  288. provided.
  289. - 10th May 2008 libburn-0.4.6 supports formatting and writing of BD-RE,
  290. full nominal speed for DVD-RAM and BD-RE. cdrskin has a unified blank
  291. type with automatic media state recognition.
  292. - 17th May 2008 an old bug with DVD-RAM and now with BD-RE is fixed by
  293. libburn-0.4.8. So libisoburn can now perform emulation of multisession
  294. on those media.
  295. - 19th May 2008 libisoburn-0.1.6 brings better table-of-content emulation
  296. on overwriteble media and disk files.
  297. - 1st Jun 2008 libisofs-0.6.6 fixes some problems around device files.
  298. - 3rd Jun 2008 libisoburn-0.1.8 fixes a bug with overwriteable media.
  299. - 23rd Jun 2008 libisoburn-0.2.0 introduces extraction of files from
  300. ISO images.
  301. - 16th Jul 2008 libburn-0.5.0 handles systems with no /dev/sr* but only
  302. /dev/scd*.
  303. - 19th Jul 2008 libisoburn/xorriso-0.2.2 can do multi-session in mkisofs
  304. and cdrecord style. xorriso now can serve underneath growisofs.
  305. - 20th Aug 2008 libburn-0.5.2 revokes the necessity that a drive must be
  306. enumerable in order to be addressable. Enumeration is enhanced by examining
  307. /proc/sys/dev/cdrom/info.
  308. - 24th Aug 2008 libisoburn/xorriso-0.2.4 introduces a media readability check
  309. with data retrieval option.
  310. - 18th Sep 2008 libisofs-0.6.8 supports ISO 9660 Level 3 which can represent
  311. very large data files in the image.
  312. - 20th Sep 2008 libisoburn/xorriso-0.2.6 takes into respect the new Level 3
  313. capabilities of libisofs.
  314. - 6th Oct 2008 libburn-0.5.4 adjusts the changes of 0.5.2 to the needs of
  315. Linux kernel 2.4 and introduces human readable SCSI error messages.
  316. - 6th Oct 2008 libisofs-0.6.10 fixes two bugs which prevented adding and
  317. manipulation of ISOLINUX boot images.
  318. - 15th Oct 2008 libisoburn/xorriso-0.2.8 can activate and maintain an
  319. ISOLINUX boot image by an EL Torito boot record.
  320. - 12th Nov 2008 libburn-0.5.6 fixes usage of freed memory by the fifo thread
  321. of an aborted burn run.
  322. - 26th Nov 2008 libisofs-0.6.12 can produce a ISOLINUX isohybrid MBR on the fly
  323. and can produce ISO images which resemble old mkisofs images.
  324. - 2nd Dec 2008 libisoburn-0.3.0. xorriso now is ready for exotic character
  325. sets, for legacy FreeBSD systems which expect an outdated Rock Ridge
  326. signature, and for producing ISO images with MBR which boot from hard disk
  327. or USB stick. Three minor bugs were fixed.
  328. - 7th Dec 2008 libburn-0.5.8 prevents a SIGSEGV with weird CD table-of-content
  329. and improves BD-RE formatting.
  330. - 9th Dec 2008 Our project received a donation from Thomas Weber.
  331. - 2nd Jan 2009 libburn-0.6.0 learned to format BD-R and write to either
  332. formatted or unformatted BD-R.
  333. - 6th Jan 2009 libisoburn-0.3.2. xorriso can produce and execute commands for
  334. mounting older sessions from all kinds of media. Pseudo-drives outside the
  335. /dev/ tree can be addressed without prefix "stdio:".
  336. - 20th Feb 2009 libburn-0.6.2 source release now compiles out of the box
  337. on FreeBSD.
  338. - 28 Feb 2009 libisofs-0.6.14 can record ACLs and Extended Attributes xattr
  339. in its ISO images.
  340. - 01 Mar 2009 libisoburn-0.3.4. xorriso makes use of the ACL and xattr
  341. capabilities provided by libisofs for xorriso backup features.
  342. - 11 Mar 2009 libisofs-0.6.16 of libisofs fixes two bugs which on Solaris
  343. prevented to navigate the ISO images by ".." and to recognize the Rock Ridge
  344. extensions of ISO images. The ban to build libisofs on operating systems
  345. other than Linux and FreeBSD has been lifted.
  346. - 13 Mar 2009 libburn-0.6.4 got a dummy adapter for SCSI/MMC command transport.
  347. It will show no drives and thus libburn will only be able to perform
  348. operations on "stdio:" pseudo drives. Nevertheless this was precondition
  349. to lift the ban to build libburn on operating systems other than Linux
  350. and FreeBSD.
  351. - 16 Mar 2009 libisoburn-0.3.6: xorriso uses RRIP version 1.10 as default
  352. in order to be mountable where mkisofs images are mountable.

  629. Clarification in my name and in the name of Mario Danic, upcoming copyright
  630. holders on toplevel of libburnia. To be fully in effect after the remaining
  631. other copyrighted code has been replaced by ours and by copyright-free
  632. contributions of our friends:
  633. ------------------------------------------------------------------------------
  634. We, the copyright holders, agree on the interpretation that dynamical linking
  635. of our libraries constitutes "use of" and not "derivation from" our work in
  636. the sense of GPL, provided those libraries are compiled from our unaltered
  637. code or from altered code published under GPL.
  638. So we will not raise legal protest if you link our libraries dynamically with
  639. applications which are not under GPL, or if you distribute our libraries
  640. and application tools in binary form, as long as you fulfill the usual
  641. condition of GPL to offer a copy of their source code -altered or unaltered-
  642. under GPL.
  643. We ask you politely to use our work in open source spirit
  644. and with the due reference to the entire open source community.
  645. If there should really arise the case where above clarification
  646. does not suffice to fulfill a clear and neat request in open source
  647. spirit that would otherwise be declined for mere formal reasons,
  648. only in that case we will duely consider to issue a special license
  649. covering only that special case.
  650. It is the open source idea of responsible freedom which will be
  651. decisive and you will have to prove that you exhausted all own
  652. means to qualify for GPL.
  653. For now we are firmly committed to maintain one single license: GPL.
