Xpdf for OpenVMS/Alpha

With some effort, I've managed to compile Xpdf version 3.00pl3 (the
latest as of this writing) for OpenVMS/Alpha. This is an up-to-date PDF
viewer (analogous to Adobe Acrobat) for VMS users.

Xpdf requires two shared libraries: T1Lib and Freetype. As of this
writing, the latest versions of each are 5.0.2 and 2.1.10, respectively.
Xpdf also requires Ghostscript, in order to use the Type 1 fonts that
come with it (especially the 13 required PostScript fonts).

To make it convenient to install and remove, I have packaged the
compiled binaries in PCSI (PolyCenter Software Installation utility)
format, and included the Ghostscript package from the Freeware CD-ROM.
The easiest way to install Xpdf is to download all four required
packages (of course, you can skip any that are already installed on your
computer)

    * FreeType 2.1.10
      <ftp://frank.harvard.edu/pub/coldwell/vms/xpdf/FREETYPE-V0201.SFX_AXPEXE>
    * GhostScript 6.5
      <ftp://frank.harvard.edu/pub/coldwell/vms/xpdf/ghostscript-v0650.pcsi_sfx_axpexe>
    * T1Lib 5.0.2
      <ftp://frank.harvard.edu/pub/coldwell/vms/xpdf/T1LIB-V0500.SFX_AXPEXE>
    * XPdf 3.00pl3
      <ftp://frank.harvard.edu/pub/coldwell/vms/xpdf/XPDF-V0300.SFX_AXPEXE>

into a single directory, unpack the self-extracting archives, and then run

    $ PRODUCT INSTALL XPDF
    

from inside that directory. The PCSI utility should automatically
install the needed dependencies.

These packages have been tested on OpenVMS/Alpha version 7.3-1, the
latest version available on the Hobbyist CD Media.


    A note on header files

I decided to put all the header files that come with the two shared
libraries (T1Lib and FreeType) into text libraries. I find it easier to
add a text library to the end of the compile command, thus:

    $ CC FOO.C+SYS$LIBRARY:FREETYPE2.TLB
    

rather than go through all the usual logical name gymnastics required to
deal with include paths with subdirectories (e.g. "#include <sys/types.h>").


    Source code

The source code with my modifications to create the OpenVMS/Alpha
packages above is available below. In each case, it should be possible
to unpack the archive, set your default directory to the toplevel
directory created by the archive, and run MMS/EXT to build the binaries
and create the package.
