By Thomas Schmitt Integrated sub project of libburnia-project.org but also published via: http://scdbackup.sourceforge.net/xorriso_eng.html http://scdbackup.sourceforge.net/xorriso-0.1.0.tar.gz Copyright (C) 2006-2008 Thomas Schmitt, provided under GPL version 2. ------------------------------------------------------------------------------ xorriso is a program which maps file objects from POSIX compliant filesystems into Rock Ridge enhanced ISO 9660 filesystems and allows session-wise manipulation of such filesystems. It can load the management information of existing ISO images and it writes the session results to optical media or to filesystem objects. Currently it is only supported on Linux with kernels >= 2.4. A special property of xorriso is that it needs neither an external ISO 9660 formatter program nor an external burn program for CD or DVD but rather incorporates the libraries of libburnia-project.org . By using this software you agree to the disclaimer at the end of this text: "... without even the implied warranty ..." Compilation, First Glimpse, Installation The most simple way to get xorriso is the xorriso standalone tarball. Prerequisites: The tarball contains anything that is needed except libc and libpthread. libreadline and the libreadline-dev headers will make dialog mode more convenient, but are not mandatory. Obtain xorriso-0.1.0.tar.gz, take it to a directory of your choice and do: tar xzf xorriso-0.1.0.tar.gz cd xorriso-0.1.0 Within that directory execute: ./configure --prefix=/usr make This will produce a binary named ./xorriso/xorriso which you may strip to reduce it in size strip ./xorriso/xorriso You may copy or move it to a directory where it can be found by the shell, you may execute xorriso at the place where it was built, or you may execute as superuser: make install For general concepts, options and usage examples see man 1 xorriso This man page is part of the tarball as xorriso/xorriso.1 You may get a first glimpse by man ./xorriso/xorriso.1 It gets installed with "make install" but may also be placed manually in the ./man1 directory below one of the directories mentioned in environment variable $MANPATH. Drives and Disk File Objects The user of xorriso needs rw-permission for the CD burner device. A list of rw-accessible drives can be obtained by xorriso -devices CD devices which offer no rw-permission are invisible to normal users. The superuser should be able to see any usable drive and then set the permissions as needed. The output of xorriso -devices might look like 0 -dev '/dev/sr0' rwrw-- : 'TSSTcorp' 'CDDVDW SH-S203B' 1 -dev '/dev/hda' rwrw-- : 'HL-DT-ST' 'DVD-ROM GDR8162B' Full and insecure enabling of both for everybody would look like chmod a+rw /dev/sr0 /dev/hda This is equivalent to the traditional setup chmod a+x,u+s cdrecord. I strongly discourage to run xorriso with setuid root or via sudo ! It is not checked for the necessary degree of hacker safety. Consider to put all authorized users into group "floppy", to chgrp the device file to that group and to disallow w-access to others. A possible source of problems are hald or other automounters. If you can spot a process "hald-addon-storage" with the address of your desired drive, then consider to kill it. If you cannot get rid of the automounter that easily, try whether it helps to always load the drive tray manually before starting a write run of xorriso. Wait until the drive light is off. Better try to unmount an eventually mounted media before a write run. Besides true optical drives, xorriso can also address disk files as input or output drives. The addresses of the disk files have to be preceded by "stdio:". Like: xorriso -dev stdio:/tmp/pseudo_drive ...more arguments... libisoburn xorriso is based on libisofs which does ISO 9600 filesystem aspects and on libburn which does the input and output aspects. Parts of this foundation are accessed via libisoburn, which is closely related to xorriso. libisoburn takes care for the emulation of ISO 9660 multi-session on overwriteable media or random access files. It also encapsulates the coordination between libisofs and libburn. The sourcecode of all three libraries is included in the xorriso standalone tarball. But you may as well get and install releases of libburn and libisofs, in order to be able to install a release of libisoburn which produces a dynamically linked xorriso binary. This binary is leaner but depends on properly installed libraries of suitable revision. Dynamic library requirements for libisoburn-0.1.0 : - libburn.so.4 , version 0.4.2 or higher - libisofs.so.6 , version 0.6.2 or higher Standalone xorriso has less runtime dependencies and can be copied more freely. ------------------------------------------------------------------------------ This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License version 2 as published by the Free Software Foundation.
