CDRTOOLS compiles without changes on any UnixWare 7.0.1 or later installation 
having the UnixWare/OpenServer DevKit (UODK) or GCC-2.95 and smake-1.2 
installed.

You can get pre-packaged, pkgadd installable binaries from:

Some general notes on CDRTOOLS are available from:

   http://www.sco.com/skunkware/cdrtools/SCO-NOTES.html


Limitations for CDRTOOLS-1.8 on UnixWare:

1) SCO UnixWare 2.1.X and UnixWare 7.0.0 are not supported
   - UW2.1.X will compile/work with little changes
   - UW7.0.0 wasn't tested at all 

2) There is only support for SCSI devices

3) UnixWare 7.0.1 requires additional PTF's to enable some
   host bus adapters to work with a logical block size of more than
   512 bytes. (Please see the above SCO_NOTES document for details!)

===================================================================
NOTE: cdrecord now supports the -scanbus option. Therefore the 
      old addressing methods are NO LONGER AVAILABLE !!!
      
      As UnixWare 7.1.1 doesn't allow to open the passthrough
      interface for disks, this is disabled by default. 
      cdrecord -scanbus will therefore only list devices other
      than disks. To enable the scanning of disks, you need to
      set an environment variable "LIBSCG_SCAN_ALL".
      
      Be warned, doing so might lock your disk subsystem!
===================================================================

The correct dev= syntax on UnixWare 7 is:

    dev=scsibus,target,lun	(and scsibus is scsibus now!!!)

A sample output from cdrecord -scanbus looks like:

#cdrecord -scanbus

        0,7,0     7) *

The first column showing the triple x,y,z tells you the address to use.

As you can see the TEAC CD-R56S CD-Writer does have the following address:

     dev=0,6,0
     
===================================================================
           THE OLD ADDRESSING IS NO LONGER AVAILABLE!
	    
         PLEASE ADJUST YOUR /etc/default/cdrecord FILES!
===================================================================

Running cdrecord with the old address method will result in an error!

cdrecord: Invalid argument. Open by 'devname' no longer supported on this OS. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.


To compile cdrtools, you need 'smake' from:

   ftp://ftp.sco.com/skunkware/uw7/Packages


or 'gmake'. Smake is preferred as gmake bugs will cause bogus warnings
and may confuse about the state of the make run.
