CDRTOOLS compiles without changes on any SCO OpenServer 5.0.4
or later installation having the SCO DevSys or GCC-2.95 and 
smake-1.2a04 or later installed. 

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

Some general notes on CDRTOOLS are available from:

Limitations for CDRTOOLS-1.8 on SCO OpenServer 5:

1) SCO OpenServer 5.0.0 and 5.0.2 are unsupported!
  
2) There is only support for SCSI devices

3) There no support for AHA 154X scsi controllers

===================================================================
NOTE: cdrecord now supports the -scanbus option. Therefore the 
      old addressing methods are NO LONGER AVAILABLE !!!
===================================================================
      
As there is no real generic SCSI driver, cdrecord uses the pass through
ioctl of the cdrom target driver (Srom).

The correct dev= syntax on SCO Openserver 5 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!

To compile cdrtools, you need 'smake' version 1.2a04 or later from:

   ftp://ftp.sco.com/skunkware/osr5/vols


Please make sure you use smake-1.2a04 or later, cause smake-1.2 versions
before a04 will coredump on the compilation of cdrtools on OpenServer.
