Antiword 0.36 for VMS

Antiword is a MS Word document file reader.
Author: Adri van Os. Homepage: www.winfield.demon.nl

With a minimum of changes, I have made a version working on VMS ( Alpha, Compaq C V6.+ , Vax should work as well).

Build instructions for VMS

Get the distribution from the programmers/Linux version at linux/antiword-0.36.tar.gz , or from here
Decompress using gzip, then untar and set directory to [.antiword-0_36] .

Get VMS-specific build-files packed into antiword_vms_files.zip. Fetch this archive, and unpack in [.antiword-0_36] .
If You have GNU make (gmake) with DCL: Execute "(g)make -f makefile.vms" . With GNV bash: make -f makefile.vms_bash .
If You have MMS , simply type "MMS" using the DESCRIP.MMS descriptor file provided here.

Without make or MMS, compile everything, except main_r, then link main_u (the common Unix- and VMS main program) and all other object files. (all commands are in vms_make.com).
Informed by Peter Weaver, who compiled on Vax VMS 7.1, DECC 5.7, it needs an additional definition in misc_vms_prefix.c . I made the definition conditionalized on CRTL < 7 . This may or may not be correct; if somebody with a DECC version between 5.7 and 6.4 can prove it, please inform me. Maybe one has to make the condition on the DECC rather than the CRTL version.
I had the opportunity to compile and link with V 0.35 with DEC C V5.6-003 on OpenVMS VAX V7.1, and -surprise- it does not need any change. Test and see!
On Alpha VMS 7.1 with DECC 5.6: builds correctly using @vms_make "" "" CC/STANDARD=VAXC or MMS /Macro=("CC=CC/STANDARD=VAXC") .
Until it is clear, what the right definitions are, I will not include a changed misc.c in the distribution.
I definitely have no way to test, if it compiles with Vaxc or GCC !

Optional changes for VMS

Global file directory and the /usr path

You may want to change the location of the global file directory ( macro GLOBAL_ANTIWORD_DIR in header-file antiword.h ) holding the files from the [.resources] subdirectory:
change /usr/share/antiword to a different location (in Unix syntax), unless You define a VMS logical device "/usr" ( USR:[SHARE.ANTIWORD] ).
On my system the logical usr looks like this:
"USR" [super] = "SYS$SYSDEVICE:[UTIL.]" [concealed] (LNM$SYSTEM_TABLE)
I will not change the source for this , since there is no convention in VMS for user-shared files .
VMS 7.3-1 introduces a SYS$POSIX_ROOT logical: simply create the usr/ directory tree under SYS$POSIX_ROOT.
V 0.34 adds an environment-variable ANTIWORDHOME to find the global setup directory if not /usr/share/antiword . Define it as a VMS logical, directory-name in VMS-syntax ( dev:[directory] ).

DEBUG option and the /tmp path

To compile the sources with the DEBUG option, have a look into the *2eps.c files: they write image files to a directory /tmp/pics/...

Either define a concealed logical TMP (e.g. to point to sys$scratch), or change the 3 source files to point to sys$scratch: instead of /tmp/pics/.
All newer VMS versions (since V7.?) contain a DECC RTL, with a specific handling of "/tmp": it translates to sys$scratch, if no "tmp" logical is defined. So usually it is enough to create a directory [.pics] in your user root.

Installation:

define a foreign command pointing to antiword.exe
or
copy antiword.exe into dcl$path:

Setup/font files:

System-wide: copy the [.resources] files into the directory defined by /usr/share/antiword
or leave the [.resources] subdirectory in place, and let the user (or sys$sylogin) execute this procedure: antiword_setup.com
Private: create directory [.ANTIWORD] in sys$login:
copy the [.resources] files into the newly created directory.

Usage

Produce a postscript file from a word-document:

pipe antiword -p a4 file.doc >file.ps
A DCL commandfile in our DCL$PATH directory does the postscript conversion and X11 display with Ghostscript in one go: wordviewer.com
Use it in a commandline like this: wordviewer testdoc

Comment applying to all GNU/Unix style programs compiled with DECC:
The interpretation of command-line switches and path-names can be influenced by several DECC$* logical names, most important ones are:


$ define DECC$ARGV_PARSE_STYLE "ENABLE"
$ SET PROCESS/PARSE_STYLE=EXTENDED 

 These 2 settings  preserve case of foreign command-lines
 ( otherwise `antiword -L` has to be typed as `antiword -"L"` )

$ define DECC$DISABLE_TO_VMS_LOGNAME_TRANSLATION "ENABLE"  
 path foo/bar translates to [.foo]bar; if disabled, it translates to foo:[bar]
 (but some programs will not work , java in particular !)

How to define a global antiword directory /usr/share/antiword :

Let's assume the global directory in VMS is SYS$SYSDEVICE:[UTIL.SHARE.ANTIWORD]
$ dir sys$sysdevice:[util.share.antiword]

 Directory SYS$SYSDEVICE:[UTIL.SHARE.ANTIWORD]
 8859-1.TXT;1        ...

$ define/trans=concealed usr sys$sysdevice:[util.]
$ ls /usr/share/antiword/

 8859-1.txt   ...

This way "/usr/share/antiword/" in the C program is equvalent to SYS$SYSDEVICE:[UTIL.SHARE.ANTIWORD]
