On top of libburn there is implemented cdrskin 0.3.8, a limited cdrecord
|
2006-08-18 17:03:41 +00:00
|
|
|
compatibility wrapper which allows to use some libburn features from
|
|
|
|
the command line.
|
|
|
|
Interested users of cdrecord are invited to participate in the development
|
2006-09-01 08:49:31 +00:00
|
|
|
of cdrskin. Contact: scdbackup@gmx.net or libburn-hackers@pykix.org .

Important :
|
|
|
|
This software is provided as is. There is no warranty implied and no
|
|
|
|
protection against possible damages. You use this on your own risk.
|
|
|
|
Don't blame me or other authors of libburn if anything goes wrong.
|
|
|
|
|
|
|
|
I used it on my own risk with :
|
2006-10-25 15:23:11 +00:00
|
|
|
SuSE 7.2, kernel 2.4.4, ide-scsi emulation, LITE-ON LTR48125S CD burner, 2002
|
|
|
|
SuSE 9.0, kernel 2.4.21, ide-scsi emulation, LG GSA-4082B CD/DVD burner, 2004
|
|
|
|
NEC ND-4570A CD/DVD burner, 2006
|
|
|
|
RIP-14.4, kernel 2.6.14, no ide-scsi, with all above burners
|
2006-08-18 17:03:41 +00:00
|
|
|
|
|
|
|
It fails to compile or run on SuSE 6.4 (kernel 2.2.14).
|
|
|
|
It does not find the IDE CD burner on SuSE 7.2 without ide-scsi.
|
|
|
|
Other people sucessfully tested cdrskin on several kernel 2.6 based x86 Linux
|
|
|
|
systems, including 64 bit systems. (Further reports are welcome.)

|
|
|
|
2007-07-20 18:13:17 +00:00
|
|
|
Obtain cdrskin-0.3.8.tar.gz, take it to a directory of your choice and do:
|
2006-08-18 17:03:41 +00:00
|
|
|
|
2007-07-20 18:13:17 +00:00
|
|
|
tar xzf cdrskin-0.3.8.tar.gz
|
|
|
|
cd cdrskin-0.3.8
|
2006-08-18 17:03:41 +00:00
|
|
|
|
2006-12-03 15:56:27 +00:00
|
|
|
Or obtain a libburnia.pykix.org SVN snapshot,
|
2006-08-21 22:39:56 +00:00
|
|
|
go into the toplevel directory of the snapshot (e.g. cd libburn_pykix ),
|
|
|
|
and execute the autotools script ./bootstrap . Use autools version >= 1.7 .
|
2006-08-18 17:03:41 +00:00
|
|
|
|
2007-07-20 18:13:17 +00:00
|
|
|
Within that toplevel directory of either cdrskin-0.3.8 or libburn then execute:
|
2006-08-18 17:03:41 +00:00
|
|
|
|
|
|
|
./configure
|
|
|
|
make
|
|
|
|
|
|
|
|
(Note: there are next-level directories "libburn" and "cdrskin". Those
|
|
|
|
would be the wrong ones. Meant is the highest directory of tarball resp.
|
|
|
|
SVN download. Among others containing files "AUTHORS", "configure",
|
|
|
|
"Makefile.am", as well as directories "libburn" and "cdrskin".)
|
|
|
|
|
|
|
|
This will already produce a cdrskin binary. But it might be necessary to
|
|
|
|
install libburn in order to use this binary. Installation of libburn is
|
|
|
|
beyond the scope of cdrskin. For this, see included libburn docs.
|
|
|
|
|
|
|
|
In order to surely get a standalone binary, execute
|
|
|
|
|
|
|
|
cdrskin/compile_cdrskin.sh
|
|
|
|
|
2006-11-02 12:21:14 +00:00
|
|
|
Version identification and help texts available afterwards:
|
2006-09-15 10:59:12 +00:00
|
|
|
cdrskin/cdrskin -version
|
2006-08-18 17:03:41 +00:00
|
|
|
cdrskin/cdrskin --help
|
|
|
|
cdrskin/cdrskin -help
|
2006-12-13 22:20:16 +00:00
|
|
|
man cdrskin/cdrskin.1
|
2006-08-18 17:03:41 +00:00
|
|
|
|
|
|
|
Install (eventually as superuser) cdrskin to a directory where it can be found:
|
2006-09-15 10:59:12 +00:00
|
|
|
If cdrskin was already installed by a previous version, or by "make install"
|
2006-09-15 07:51:50 +00:00
|
|
|
in the course of this installation, then find out where:
|
|
|
|
which cdrskin
|
2006-09-15 10:59:12 +00:00
|
|
|
Copy your standalone binary to exactly the address which you get as reply
|
|
|
|
|
|
|
|
cp cdrskin/cdrskin /usr/bin/cdrskin
|
|
|
|
|
|
|
|
Check the version timestamps of the globally installed binary
|
|
|
|
cdrskin -version
|
2006-09-15 07:51:50 +00:00
|
|
|
|
2006-08-18 17:03:41 +00:00
|
|
|
It is not necessary for the standalone cdrskin binary to have libburn
|
|
|
|
installed, since it incorporates the necessary libburn parts at compile time.
|
|
|
|
It will not collide with an installed version of libburn either.
|
|
|
|
But libpthread must be installed on the system and glibc has to match. (See
|
|
|
|
below for a way to create a statically linked binary.)
|
|
|
|
|
2006-12-13 22:09:42 +00:00
|
|
|
To install the man page, you may do: echo $MANPATH and choose one of the
|
|
|
|
listed directories to copy the man-page under its ./man1 directory. Like:
|
|
|
|
cp cdrskin/cdrskin.1 /usr/share/man/man1/cdrskin.1
|
|
|
|
|
2006-08-18 17:03:41 +00:00
|
|
|
|
|
|
|
Usage
|
|
|
|
|
|
|
|
The user of cdrskin needs rw-permission for the CD burner device.
|
|
|
|
A list of rw-accessible drives can be obtained by
|
|
|
|
|
|
|
|
cdrskin --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. If this hangs then there is a drive with
|
|
|
|
unexpected problems (locked, busy, broken, whatever). You might have to
|
|
|
|
guess the address of your (non-broken) burner by other means, then.
|
2007-04-23 15:43:51 +00:00
|
|
|
On Linux 2.4 this would be some /dev/sgN and on 2.6. some /dev/srM or /dev/hdX.
|
2006-08-18 17:03:41 +00:00
|
|
|
|
|
|
|
The output of cdrskin --devices might look like
|
|
|
|
|
2007-04-23 15:43:51 +00:00
|
|
|
0 dev='/dev/sr0' rwrwr- : '_NEC' 'DVD_RW ND-4570A'
|
|
|
|
1 dev='/dev/sr1' rwrw-- : 'HL-DT-ST' 'DVDRAM GSA-4082B'
|
2006-08-18 17:03:41 +00:00
|
|
|
|
|
|
|
So full and insecure enabling of both for everybody would look like
|
|
|
|
|
2007-04-23 15:43:51 +00:00
|
|
|
chmod a+rw /dev/sr0 /dev/sr1
|
2006-08-18 17:03:41 +00:00
|
|
|
|
|
|
|
I strongly discourage to run cdrskin with setuid root or via sudo !
|
|
|
|
It is not checked for the necessary degree of hacker safety.

Inspiration and Standard
|
|
|
|
|

|
|
For the original meaning of cdrecord options see :
|
|
|
|
man cdrecord
|
|
|
|
(http://cdrecord.berlios.de/old/private/man/cdrecord-2.0.html)
|
|
|
|
Do not bother Joerg Schilling with any cdrskin problems.
|
|
|
|
(Be cursed if you install cdrskin as "cdrecord" without clearly forwarding
|
|
|
|
this "don't bother Joerg" demand.)
|
|
|
|
cdrskin does not contain any bytes copied from cdrecord's sources. Many bytes
|
|
|
|
have been copied from the message output of cdrecord runs, though. I am
|
|
|
|
thankful to Joerg Schilling for every single one of them.
|
|
|
|
I have the hope that Joerg feels more flattered than annoyed by cdrskin.

Drive Addressing
|
|
|
|
|
|
|
|
Drives get addressed either via their cdrecord-style addresses as listed
|
|
|
|
with option -scanbus (see below "Pseudo-SCSI Adresses") or via the paths
|
|
|
|
of device files.
|
|
|
|
Not only device files listed by --devices may be used but also device files
|
|
|
|
which via their major,minor numbers point to the same device driver as
|
|
|
|
a listed device file.
|
|
|
|
|
|
|
|
Helpful with Linux kernel 2.4 is a special SCSI feature:
|
|
|
|
It is possible to address a scsi(-emulated) drive via associated device files
|
|
|
|
which are not listed by option --devices but point to the same SCSI addresses
|
|
|
|
as listed device files. This addressing via e.g. /dev/sr0 or /dev/scd1 is
|
|
|
|
compatible with generic read programs like dd and with write program growisofs.
|
|

Pseudo-SCSI Adresses
|
|
|
|
|
2006-10-23 11:31:37 +00:00
|
|
|
cdrecord and cdrskin share the syntax of SCSI addresses but not necessarily
|
2006-09-23 15:15:54 +00:00
|
|
|
the meaning of the components. A cdrecord-style address for cdrskin
|
|
|
|
[prefix:]scsibus,target,lun
|
|
|
|
can be interpreted in two different modes.
|
|
|
|
|
2006-10-11 19:21:26 +00:00
|
|
|
Standard mode tries to be compatible to original cdrecord. This should be true
|
2007-04-23 15:43:51 +00:00
|
|
|
with (emulated) SCSI where the device file /dev/s[rg]N with is looked up with
|
|
|
|
matching scsibus,target,lun as given by the operating system.
|
2006-10-11 19:21:26 +00:00
|
|
|
With dev=ATA: or dev=ATAPI: the translation to /dev/hdX is purely literal
|
|
|
|
but matches the cdrecord addresses on all systems tested so far:
|
|
|
|
X = 'a' + 2 * scsibus + target
|
|
|
|
where target only may have the values 0 or 1.
|
2006-09-23 18:23:18 +00:00
|
|
|
|
|
|
|
In this mode, option -scanbus will list only SCSI devices unless option
|
|
|
|
dev=ATA or dev=ATAPI are given, which will suppress SCSI devices and only
|
|
|
|
show IDE drives (i.e. /dev/hdX without ide-scsi emulation).
|
|
|
|
|
|
|
|
|
|
|
|
In mode --old_pseudo_scsi_adr there is a scsibus,target,lun representation
|
|
|
|
which has nothing to do with SCSI and thus is not compatible to cdrecord.
|
|
|
|
Each number triple corresponds either to a device file address or to a
|
|
|
|
libburn drive number.
|
2006-08-18 17:03:41 +00:00
|
|
|
Component "scsibus" indicates the translation method. Defined busses are:
|
|
|
|
0 target is the libburn drivenumber as listed with --devices
|
|
|
|
1 associated to device file /dev/sgN , target chooses N
|
|
|
|
2 associated to device file /dev/hdX , target 0='a', 1='b' ..., 25='z'
|
|
|
|
|
2007-04-23 15:43:51 +00:00
|
|
|
So "1,1,0" is /dev/sg1 (resp. its /dev/sr*), "2,3,0" is /dev/hdd,
|
|
|
|
"0,2,0" is libburn drive #2 at some unspecified device file.
|
2006-08-18 17:03:41 +00:00
|
|
|
This scheme shall help to keep cdrecord-style addresses stable and exchangeable
|
|
|
|
between users without excluding drives with unexpected device addresses.
|
|
|
|
The numbering on bus 0 is prone to arbitrary changes caused by changes in
|
|
|
|
drive accessability.
|
|
|
|
Further busses may emerge as libburn evolves. "prefix" and "lun" may get
|
|
|
|
a meaning. To stay upward compatible, use addresses as printed by -scanbus.
|
|
|
|
|

User Defined Device Address Translation
|
2006-09-23 15:15:54 +00:00
|
|
|
|
2006-08-18 17:03:41 +00:00
|
|
|
Some programs or users have their own ideas about the address of their burner.
|
|
|
|
K3b 0.10 for example derives cdrecord addresses by own examination of the
|
|
|
|
devices and not by calling cdrecord -scanbus.
|
2006-10-11 19:21:26 +00:00
|
|
|
Standard mode will hopefully be fully compatible with their ideas.
|
2006-09-23 18:23:18 +00:00
|
|
|
|
|
|
|
Old frontends which do not know dev=ATA or dev=ATAPI and which do ask their
|
|
|
|
"cdrecord" via -scanbus may be well served with option --old_pseudo_scsi_adr .
|
2006-09-23 15:15:54 +00:00
|
|
|
|
2006-10-25 15:23:11 +00:00
|
|
|
To direct any remaining stubborn callers to the appropriate drives, cdrskin
|
|
|
|
allows to define device address aliases. Like
|
2007-04-23 15:43:51 +00:00
|
|
|
cdrskin dev_translation=+1,0,0+/dev/sr1 \
|
|
|
|
dev_translation=+ATA:1,0,0+/dev/sr1 \
|
2006-10-25 15:23:11 +00:00
|
|
|
dev_translation=-"cd+dvd"-0,1,0 \
|
2006-08-18 17:03:41 +00:00
|
|
|
...
|
|
|
|
Any of the addresses dev=1,0,0, dev=ATA:1,0,0, dev=cd+dvd will be mapped to
|
2007-04-23 15:43:51 +00:00
|
|
|
/dev/sr1 resp. to 0,1,0.
|
2006-08-18 17:03:41 +00:00
|
|
|
The first character after "dev_translation=" defines the character which
|
|
|
|
separates the two parts of the translation pair. (Above: "+" and "-".)
|
|
|
|
|
|
|
|
In K3b 0.10 it is possible to employ alternative writer programs by setting
|
|
|
|
their full path (e.g. /usr/bin/cdrskin) in menu
|
|
|
|
Settings:Configure K3b...:Programs:Search Path
|
|
|
|
and to make them default in menu
|
|
|
|
Settings:Configure K3b...:Programs:Programs:
|
|
|
|
A suitable setting for "cdrecord" in menu
|
|
|
|
Settings:Configure K3b...:Programs:User Parameters
|
|
|
|
would then probably be
|
2007-04-23 15:43:51 +00:00
|
|
|
-v dev_translation=+1,0,0+/dev/sr1
|
2006-08-18 17:03:41 +00:00
|
|
|
You will learn from button "Show Debugging Output" after a failed burn run
|
|
|
|
what cdrecord command was used with what address "dev=...". This address "..."
|
|
|
|
will be the right one to replace "1,0,0" in above example.
|
|
|
|
|
|
|
|
|
|
|
|
Startup Files
|
|
|
|
|
|
|
|
If not --no_rc is the first argument then cdrskin attempts on startup to read
|
|
|
|
arguments from the following three files:
|
2006-11-14 08:33:34 +00:00
|
|
|
/etc/default/cdrskin
|
2006-08-18 17:03:41 +00:00
|
|
|
/etc/opt/cdrskin/rc
|
2006-12-11 10:14:43 +00:00
|
|
|
/etc/cdrskin/cdrskin.conf
|
2006-08-18 17:03:41 +00:00
|
|
|
$HOME/.cdrskinrc
|
|
|
|
The files are read in the sequence given above.
|
2006-09-27 08:07:45 +00:00
|
|
|
Each readable line is treated as one single argument. No extra blanks.
|
|
|
|
A first character '#' marks a comment, empty lines are ignored.
|
2006-08-18 17:03:41 +00:00
|
|
|
|
|
|
|
Example content of a startup file:
|
2006-09-27 08:07:45 +00:00
|
|
|
# This is the default device
|
|
|
|
dev=0,1,0
|
|
|
|
# To accomodate to eventual remnant cdrskin-0.2.2 addresses
|
|
|
|
dev_translation=+1,0,0+0,1,0
|
|
|
|
|
|
|
|
# Some more options
|
2007-01-11 13:28:36 +00:00

Audio CD
|
|
|
|
|
2006-10-18 17:50:24 +00:00
|
|
|
Lorenzo Taylor enabled option -audio in cdrskin (thanks !) and reports neat
|
|
|
|
results with audio data files which are :
|
2006-10-25 15:23:11 +00:00
|
|
|
headerless PCM (i.e. uncompressed)
|
2006-10-18 17:50:24 +00:00
|
|
|
44100 Hz sampling rate
|
2006-10-18 18:23:06 +00:00
|
|
|
16 bits per sample
|
2006-10-18 17:50:24 +00:00
|
|
|
stereo (2 channels)
|
2006-10-25 15:23:11 +00:00
|
|
|
little-endian byte order with option -swab, or big-endian without -swab
|
|
|
|
|
2006-10-18 17:50:24 +00:00
|
|
|
Files with name extension .wav get examined wether they are in Microsoft WAVE
|
|
|
|
format with above parameters and eventually get extracted by cdrskin itself.
|
2006-10-25 15:23:11 +00:00
|
|
|
In the same way files with name extension .au get examined wether they are
|
|
|
|
in SUN's audio format. For both formats, track format -audio and eventual
|
|
|
|
endianness option -swab are enabled automatically.
|
|
|
|
|
|
|
|
Any other formats are to be converted to format .wav with above parameters
|
|
|
|
or to be extracted as raw CD track data by commands like those given above
|
|
|
|
under "Usage examples". Those raw files need option -audio and in most cases
|
|
|
|
option -swab to mark them as little-endian/Intel/LSB-first 16-bit data.
|
|
|
|
Incorrect endianness setting results in random noise on CD.
|

I myself am not into audio. So libburn-hackers@pykix.org might be the
|
2006-09-04 19:44:39 +00:00
|
|
|
best address for suggestions, requests and bug reports.

DVD+RW and DVD-RAM
|
2006-12-21 21:46:58 +00:00
|
|
|
|
2007-01-13 14:12:07 +00:00
|
|
|
DVD+RW and DVD-RAM media get treated as blank media regardless wether they
|
|
|
|
hold data or not. Options -audio and -multi are not allowed. Only one track
|
|
|
|
is allowed. -toc does not return information about the media content.
|
2006-12-21 21:46:58 +00:00
|
|
|
Speed is counted in DVD units (i.e. 1x = 1,385,000 bytes/second). Currently
|
|
|
|
there is no difference between -sao and -tao. If ever, then -tao will be the
|
|
|
|
mode which preserves the current behavior.
|
|
|
|
|
2007-01-13 14:12:07 +00:00
|
|
|
For these media, -msinfo alone would not be enough to perform appending of an
|
|
|
|
ISO filesystem. The filesystem driver will need a hint to find the start of the
|
2006-12-23 11:24:11 +00:00
|
|
|
most recent session. For example put an ISO filesystem at address 1 GB:
|
|
|
|
mkisofs -C 0,524288 ... | \
|
|
|
|
cdrskin dev=/dev/sr0 -v fs=32m -eject speed=4 write_start_address=524288s -
|
|
|
|
The superuser may then do:
|
|
|
|
mount -t iso9660 -o ro,sbsector=524288 /dev/sr0 /mnt
|
2007-06-10 07:06:42 +00:00
|
|
|
Note: On my linux-2.4.21-215 mount works only with sbsector <= 337920 (660 MiB)
|
2006-12-23 11:24:11 +00:00
|
|
|
To extend a filesystem already existing at address 0
|
|
|
|
mkisofs -C 0,524288 -M /dev/sr0 ... | cdrskin dev=/dev/sr0 ...
|
|
|
|
Record the number 524288 for usage as first number with -C at the next
|
|
|
|
extension:
|
|
|
|
mkisofs -C 524288,1000000 ... | cdrskin write_start_address=1000000s ...
|
|
|
|
|
|
|
|
Program growisofs can append to an ISO filesystem on DVD+RW by additionally
|
|
|
|
manipulating the first session. cdrskin does not want to get involved so deep
|
|
|
|
into the format of the burned data. Be advised to use growisofs for the
|
|
|
|
task of maintaining extendable ISO-Filesystems on DVD+RW.

DVD-RW and DVD-R
|
2007-01-01 17:19:41 +00:00
|
|
|
|
2007-02-01 19:45:47 +00:00
|
|
|
DVD-RW are usable if formatted to state "Restricted Overwrite" or if in state
|
2007-02-08 14:10:05 +00:00
|
|
|
"Sequential Recording". DVD-R are always in sequential state.
|
2007-02-01 19:45:47 +00:00
|
|
|
|
2007-01-01 17:19:41 +00:00
|
|
|
"Sequential" is the state of unused media and of media previously blanked
|
|
|
|
or written by cdrecord. dvd+rw-format -blank can also achieve this state.
|
2007-02-01 19:45:47 +00:00
|
|
|
The according cdrskin option is blank=deformat_sequential .
|
|
|
|
If "Incremental Streaming" is available, then sequential media are capable
|
2007-02-08 14:10:05 +00:00
|
|
|
of multi-session like CD-R[W]. (But not capable of -audio recording.)
|
2007-02-01 19:45:47 +00:00
|
|
|
This means they need option -multi to stay appendable, need to be blanked
|
|
|
|
to be writeable from start, return useable info with -toc and -msinfo,
|
|
|
|
eventually perform appending automatically.
|
2007-02-06 21:22:41 +00:00
|
|
|
Without "Incremental Streaming" offered by the drive, only write mode DAO is
|
2007-02-08 14:10:05 +00:00
|
|
|
available with sequential DVD-R[W]. It only works with blank media, allows only
|
2007-02-06 21:22:41 +00:00
|
|
|
one single track, no -multi, and demands a fixely predicted track size.
|
2007-02-08 14:10:05 +00:00
|
|
|
(growisofs uses it with DVD-R[W] if option -dvd-compat is given.)
|
2007-02-01 19:45:47 +00:00
|
|
|
|
2007-02-08 14:10:05 +00:00
|
|
|
Overwriteable DVD-RW behave much like DVD+RW. "Restricted" refers only to the
|
2007-02-01 19:45:47 +00:00
|
|
|
granularity of random access and block size which have always to be aligned to
|
|
|
|
full 32 kB. Sequential DVD-RW are converted into overwriteable DVD-RW by
|
|
|
|
cdrskin dev=... -v blank=format_overwrite
|
|
|
|
(Command dvd+rw-format -force can achieve "Restricted Overwrite", too.)
|
|
|
|
|
2007-01-01 17:19:41 +00:00
|
|
|
Formatting or first use of freshly formatted DVD-RW can produce unusual noises
|
|
|
|
from the drive and last several minutes. Depending on mutual compatibility of
|
2007-01-02 12:54:42 +00:00
|
|
|
drive and media, formatting can yield unusable media. It seems that those die
|
2007-02-01 19:45:47 +00:00
|
|
|
too on blanking by cdrecord, dvd+rw-format or cdrskin. Perils of DVD-RW.
|
2007-01-01 17:19:41 +00:00
|
|
|
|
2007-02-01 19:45:47 +00:00
|
|
|
There are three DVD-RW formatting variants with cdrskin currently:
|
2007-01-09 21:14:47 +00:00
|
|
|
|
|
|
|
blank=format_overwrite uses "DVD-RW Quick" formatting (MMC-type 15h)
|
2007-06-10 07:06:42 +00:00
|
|
|
and writes a first session of 128 MiB. This leads to media which are expandable
|
2007-01-09 21:14:47 +00:00
|
|
|
and random addressable by cdrskin.

blank=format_overwrite_quickest uses "DVD-RW Quick" formatting (type 15h) too,
|
|
|
|
but leaves the media in "intermediate" state. In the first session of writing
|
|
|
|
one may only write sequentially to such a DVD. After that, it gets random
|
2007-02-01 19:45:47 +00:00
|
|
|
addressable by cdrskin. DVD-ROM drives might show ill behavior with them.

|
|
|
blank=format_overwrite_full uses preferrably "Full Format" (type 00h).
|
|
|
|
This formatting lasts as long as writing a full DVD. It includes writing of
|
|
|
|
lead-out which is said to be good for DVD ROM compatibility.

De-formatting options are available to make overwriteable DVD-RW sequential:
|
2007-02-01 19:45:47 +00:00
|
|
|
|
|
|
|
blank=deformat_sequential performs thorough blanking of all states of DVD-RW.
|
|
|
|
blank=all and blank=fast perform the same thorough blanking, but refuse to do
|
|
|
|
this with overwriteable DVD-RW, thus preserving their formatting. The specs
|
|
|
|
allow minimal blanking but the resulting media on my drives offer no
|
2007-02-06 21:22:41 +00:00
|
|
|
Incremental Streaming afterwards. So blank=fast will do full blanking.
|
|
|
|
|
|
|
|
blank=deformat_sequential_quickest is faster but might yield DAO-only media.

DVD+R
|
|
|
|
|
|
|
|
From the view of cdrskin they behave much like DVD-R. Each track gets wrapped
|
|
|
|
into an own session, though.

Special compilation variations
|
|
|
|
|
|
|
|
You may get a (super fat) statically linked binary by :
|
|
|
|
cdrskin/compile_cdrskin.sh -static
|
|
|
|
if your system supports static linking, at all. This will not help with kernels
|
|
|
|
which do not properly support the necessary low-level interfaces chosen by
|
|
|
|
your compile-time libraries.
|
|
|
|
|
|
|
|
A size reduced but fully functional binary may be produced by
|
|
|
|
cdrskin/compile_cdrskin.sh -do_strip
|
|
|
|
|
|
|
|
An extra lean binary with reduced capabilities is created by
|
|
|
|
cdrskin/compile_cdrskin.sh -do_diet -do_strip
|
|
|
|
It will not read startup files, will abort on option dev_translation= ,
|
|
|
|
will not have a fifo buffer, and will not be able to put out help texts or
|
|
|
|
debugging messages.

cdrskin is currently copyright Thomas Schmitt only.
|
|
|
|
It adopts the following commitment by the toplevel copyright holders:
|
|
|
|
------------------------------------------------------------------------------
|
|
|
|
|
|
|
|
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.
