========================================== Cdrtools Version 2.01 (2.01.01a15) for VMS ========================================== ======================================================================== Functional changes for VMS. 2006-09-13 SMS. -------------------------------------------- ------------------------------------------------------------------------ This kit includes MMS/MMK product builders which are new for cdrtools version 2.x. Objects, object libraries, executables, and any other system-specific files should now be placed into system-specific subdirectories in the source tree, such as [.ALPHA], [.IA64], or [.VAX]. If the large-file option is specifed (non-VAX), [.ALPHAL] or [.IA64L]. (See below for details.) Command-line case is preserved by all programs if SET PROCESS /PARSE_STYLE = EXTENDED is in effect (non-VAX, where C run-time library support exists). This obviates quoting upper-case options. All programs now have an exit handler to restore process base priority ("nice(0)"). CDDA2WAV and CDRECORD normally raise it (where privileges allow), but did not previously restore it. How much they raise it is now set by the macro NICE_DECR (currently 8, had been 20) in the VMS section of [.INCLUDE.SCHILY]XMCONFIG.H. CDDA2WAV, CDRECORD, MKISOFS, and READCD now use some VMS-specific parameters on open operations for major files. This typically enables double buffers, read-ahead, write-behind, and larger extend quantities. Users who do not override the RMS defaults (SET RMS_DEFAULT) should see significant I/O speed improvements. Users may override the new default parameters using SET RMS_DEFAULT explicitly to set different ones. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - MKISOFS Changes --------------- - New "-E" option to show ISO 9660 header (Environment) information. This shows, for example, ".mkisofsrc" file data not explicitly specified on the command line. The "-v" option now also shows whether ".mkisofsrc" was used. These changes are enabled by defining the C macro "SMS", which is done by the by the VMS builders. (Look for "SMS" in [.MKISOFS]DESCRIP_SRC.MMS.) - ODS5 extended file name support (not well tested). - Various bug fixes. (See below for details.) - The new MKISOFS option, "-find", must be anabled at build time. See comments in [.VMS]DESCRIP,MMS. It is limited to VMS systems with sufficiently recent C RTL support (feature macro _USE_STD_STAT), which may mean VMS V8.2 or newer. The implementation of the "-exec" option involves fork(), so that may be expected to fail. Enabling this feature may change the behavior of the stat() function in all programs in this collection, so it could cause problems anywhere. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - MKISOFS Diagnostic Programs --------------------------- There are some diagnostic programs related to ISO-9660 file systems hidden in the [.MKISOFS.DIAG] directory. Executables for the working ones should be created in the same directory as MKISOFS.EXE, and suitable foreign-command symbols may be created for them, if desired. (See Foreign-Command Symbols, below.) The working ones are: - isodebug print mkisofs debug info from ISO-9660 image. - isoinfo perform directory like listings of iso9660 images. - isovfy verify the integrity of an iso9660 image. Not yet working (due to UNIX screen handling, at least) are the more interactive programs: - isodump display the contents of iso9660 images. - devdump display the contents of device or filesystem images. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - VMS CD/DVD Device Specification ------------------------------- In this release, a CD/DVD drive may be specified using a normal VMS device name (physical or logical). For example, "dev=dkb500" or "dev=cdrw" (where "cdrw" is a logical name which has been defined to identify an appropriate device). As in previous cdrecord/cdrtools versions, the old standard cdrecord/cdrtools format is also allowed. That is, "dev=i,j,k" (where i, j, and k are integers), rather than a simple VMS device name. The "dev=i,j,k" specification is translated into a VMS device name as shown below. i: 0 1 2 3 4 5 6 7 8 9 ... 32 33 dka dkb dkc dkd gka gkb gkc gkd dqa dqb ... dqy dqz j: SCSI ID k: SCSI LUN (usually 0) For example, "dev=1,5,0" specifies DKB500, and "dev=8,0,0" specifies DQA0. If a SCSI adapter beyond "D" is needed, the simplest method would be to specify the actual VMS device name instead of using the "i,j,k" scheme. However, to use the "i,j,k" scheme in such a case, one could specify some nonexistent DQ device (like "dev=33,1,1"), and then define a logical name to redirect the phony device name (here, DQZ101) back to the real device. For example, if the CD/DVD drive were DKF300: $ define DQZ101 DKF300 $ cdrecord dev=33,1,1 -prcap - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - GKDRIVER -------- Some VAX systems (with older hardware and/or older VMS versions) will need to use (or work better if they use) the GKDRIVER generic SCSI driver for the CD/DVD drive, instead of the usual DKDRIVER SCSI disk driver. The indicating symptom might be an I/O failure like this: cdda2wav: invalid argument. Cannot send SCSI cmd via ioctl %SYSTEM-?-BADPARAM, bad parameter value or many (recoverable) errors like this: cdda2wav: not owner. ReadCD MMC 12: scsi sendcmd: retryable error One way to select an alternate device driver involves editing SYS$MANAGER:SYCONFIG.COM to control which driver is used for the CD/DVD device. The suggested changes shown below do three things: 1. Prevent all the system devices from being automatically configured (because that would connect the CD/DVD device using the default DKDRIVER), 2. Arrange to specify GKDRIVER for the CD/DVD device(s), and then 3. Automatically configure all the other devices. The first change is to uncomment this line in SYCONFIG.COM: $! STARTUP$AUTOCONFIGURE_ALL == 0 This prevents SYS$STARTUP:VMS$DEVICE_STARTUP.COM from configuring any devices. Then (also in SYCONFIG.COM), add the appropriate SYSGEN commands to do the configuration as desired. (Refer to VMS$DEVICE_STARTUP.COM to ensure that all the desirable things which it would normally do are moved into SYCONFIG.COM.) In this example, the CD/DVD drive is on the "A" SCSI adapter at SCSI ID 5 (normally DKA500): $ mcr sysgen ! Do the normal tasks from SYS$STARTUP:VMS$DEVICE_STARTUP.COM. connect fta0 /noadapter /drivername = ftdriver connect mpa0 /noadapter /drivername = pipedriver ! Connect the CD-R/RW drive using the generic SCSI driver. connect gka500 /noadapter ! Auto-configure everything (else). autoconfigure all exit - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Foreign-Command Symbols ----------------------- Also, as in previous cdrecord/cdrtools versions, it's usual to define foreign-command symbols for the programs. It may be helpful to gather the various program executables from their individual directories, and put them all into some more convenient directory. CDDA2WAV :== $ dev:[dir]CDDA2WAV.EXE CDRECORD :== $ dev:[dir]CDRECORD.EXE MKISOFS :== $ dev:[dir]MKISOFS.EXE READCD :== $ dev:[dir]READCD.EXE Symbol definitions like these could be added to the system-wide SYS$MANAGER:SYLOGIN.COM procedure, to a user's SYS$LOGIN:LOGIN.COM procedure, to or to some other convenient procedure, as appropriate. Alternatively, the DCL$PATH logical name can be defined to include the directory (or directories) where these programs are located. ======================================================================== Build procedure for VMS. 2006-09-19 SMS. ----------------------------------------- ------------------------------------------------------------------------ Source Tree Preparation ----------------------- The original source tree contains some symbolic links to various header files (apparently to avoid having to tell the C compiler where to find them). VMSTAR extracts these links as one-line text files which say something like: *** This file is a link to The VMS builders are able to find the header files in their original locations (using /INCLUDE), and these link files only cause problems for the VMS builders. If VMSTAR is used to recreate the source tree, then the procedure [.VMS]DISCARD_LINK_FILES.COM should be run ("@") to rename the header link files from "XXX.h" to "XXX.h_link": @ [.vms]discard_link_files.com Link files other than those for the header files should be harmless, and are not affected by this action. If a VMS-oriented Zip archive is used instead of a UNIX-oriented "tar" archive to recreate the source tree, then this procedure should be unnecessary (but harmless). - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Local Customization ------------------- Some program features may be enabled or disabled in a local configuration file, [.VMS]DESCRIP_LOCAL.MMS. (A template file is preserved as [.VMS]DESCRIP_LOCAL.MMS_TEMPLATE.) Comments in the file explain the options (briefly), and how to enable or disable them. Currently, this file affects only some features in the audio extraction program, cdda2wav. This file should be edited as desired before building the products. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Building the Products --------------------- MMS/MMK product builders are distributed throughout the source tree, and in the [.VMS] directory: [.vms]append_version.com [.vms]collect_deps.com [.vms]vax_old.opt [...]descrip*.mms Any older *.COM procedures which may still be found in the source tree are obsolete, and should not be used. In the simplest case, build the products so: SET DEFAULT [.VMS] MMS ! Or MMK. See below for more options. MMK or old versions of MMS may need to have additional macros defined on the command line, but helpful messages should explain what to do when. (Old MMS versions on VAX may need MMS$ARCH_NAME. MMK will probably need MMSDESCRIPTION_FILE.) Details of the build options are explained in [.VMS]DESCRIP.MMS. Some popular targets and options include: MMS CLEAN MMS CLEAN_ALL MMS CLEAN_EXE MMS CLEAN_OLB MMS /MACRO = (LIST=1) MMS /MACRO = (LARGE=1) ! Non-VAX. Important for DVD support, ! where files bigger than 2GB are likely. Inside the major subdirectories, "MMS /DESCRIP = [-.VMS] [...]" should work. To (re-)generate the source dependency ("[...]DESCRIP_DEPS.MMS") files, MMS (V3.5 or newer?) is needed: MMS /EXTENDED /DESCRIPTION = descrip_mkdeps.mms /SKIP To save time during program development, when these are changing often, it helps to save the intermediate .MMSD files (output from CC /MMS_DEPENDENCIES), so: MMS /EXTENDED /DESCRIPTION = descrip_mkdeps.mms /MACRO = NOSKIP=1 For details, see the comments in [.VMS]DESCRIP_MKDEPS.MMS. Linking on old VMS VAX versions may generate warnings: %LINK-W-MULPSC, conflicting attributes for psect LIB$INITIALIZE in module LIB$INITIALIZE file SYS$COMMON:[SYSLIB]STARLET.OLB; A LINK options file ([.VMS]VAX_OLD.OPT) is supplied which should help. Try adding '/MACRO = ("LINKOPTS=[-.VMS]VAX_OLD.OPT/OPTIONS")' to the MMS/MMK command. The cdrtools programs use C run-time library features which were not available before VMS V7.0. Building on VMS versions earlier than V7.0 is possible using the "backport library" features provided by DEC C V5.6 and later compilers. The details are described in the file SYS$LIBRARY:DECC$CRTL.README, which is supplied with these compilers. This file also describes the options available to deal with time zones and the newer UTC-based time functions. The builders (specifically, the .FIRST actions in [.VMS]DESCRIP_SRC_CMN.MMS) check the VMS version, and, if it is pre-V7, define the logical names DECC$CRTLMAP (as SYS$LIBRARY:DECC$CRTL.EXE) and LNK$LIBRARY (as SYS$LIBRARY:DECC$CRTL.OLB), unless the user has already defined them. This should persuade the compiler to use a suitably high value for __CRTL_VER when compiling, and a suitably complete C RTL when linking. Environments with non-default configurations may require changes from the code supplied, but it should be possible to confine any needed changes to this one region. In case of problems with the builders or the products, it's often helpful to include various software version data (VMS, C compiler, C RTL) in any problem report. The source kit includes a short program to make this easier. A normal build should create the executable: [.LIBVMS.]DECC_VER.EXE When reporting any problems, please run this program, and include its output in the problem report. If problems with the build cause a failure before this executable is built, a more limited build in the [.LIBVMS] directory may have a better chance: set default [.libvms] mms /descrip = [-.vms] [... any other options ...] ======================================================================== Source changes for VMS. 2006-09-19 SMS. ---------------------------------------- ------------------------------------------------------------------------ [.cdda2wav]cdda2wav.c Changed to use the NICE_DECR macro in nice().
