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 .

|
Compilation, First Glimpse, Installation
|
|
|
|
The most simple way to get xorriso from source code is the xorriso standalone
|
|
tarball.
|
|
|
|
Prerequisites:
|
|
The tarball contains anything that is needed except libc and libpthread.
|
|
libreadline and the readline-dev headers will make dialog mode more convenient,
|
|
but are not mandatory.
|
|
|
|
Obtain xorriso-0.1.4.pl00.tar.gz, take it to a directory of your choice and do:
|
|
|
|
tar xzf xorriso-0.1.4.pl00.tar.gz
|
|
cd xorriso-0.1.4
|
|
|
|
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...
|
|
|
|
|
|
Testing
|
|
|
|
We are quite sure that libisofs produces accurate representations of the disk
|
|
files. This opinion is founded on a lot of test burns and checks by a little
|
|
test program which compares files from the mounted image with the orignals
|
|
on disk. It uses the normal POSIX filesystem calls, i.e. no libburnia stuff.
|
|
|
|
This program is not installed systemwide but stays in the installation
|
|
directory of the xorriso tarball as test/compare_file . Usually it is
|
|
run as -exec payload of a find command. It demands at least three arguments:
|
|
The path of the first file to compare, the prefix1 to be cut off from path
|
|
and the prefix2 which gets prepended afterwards to obtain the path of the
|
|
second file to compare.
|
|
As further argument there can be -no_ctime which suppresses the comparison
|
|
of ctime date stamps.
|
|
The exit value is 0 if no difference was detected, non-0 else.
|
|
|
|
Example: After
|
|
xorriso ... -pathspecs on -add /=/original/dir -- -commit_eject all
|
|
mount /media/dvd
|
|
cd test
|
|
compare tree /media/dvd with tree /original/dir :
|
|
find /original/dir -exec ./compare_file '{}' /original/dir /media/dvd ';' \
|
|
| less
|
|
and vice versa:
|
|
find /media/dvd -exec ./compare_file '{}' /media/dvd /original/dir ';' \
|
|
| less
|
|
|
|
|
|
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 provides two services:
|
|
- Encapsulation of coordination between libisofs and libburn.
|
|
- Emulation of ISO 9660 multi-session on overwriteable media
|
|
or random access files.
|
|
|
|
The sourcecode of all three libraries is included in the xorriso standalone
|
|
tarball. It is compiled with xorriso and linked statically.
|
|
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 libisoburn.so.1
|
|
and a matching dynamically linked xorriso binary.
|
|
This binary is leaner but depends on properly installed libraries of suitable
|
|
revision.
|
|
|
|
Dynamic library and compile time header requirements for libisoburn-0.1.4 :
|
|
- libburn.so.4 , version libburn-0.4.4 or higher
|
|
- libisofs.so.6 , version libisofs-0.6.4 or higher
|
|
libisoburn and xorriso will not start with libraries which are older than their
|
|
headers seen at compile time. So compile in the oldest possible installation
|
|
setup unless you have reason to enforce a newer bug fix level.
|
|
|
|
Standalone xorriso has less runtime dependencies and can be moved more freely.
