Building XSLT under OpenVMS
|
|
===========================
|
|
|
|
Here's a summary of the issues I encountered when building XSLT under
|
|
VMS. I'd previously done the same for the LIBXML package, on which
|
|
XSLT depends.
|
|
|
|
I present this list "as is" to hopefully act as a guide to anyone
|
|
having similar problems in the future.
|
|
|
|
That's it. Good luck!

Installation kit
|
|
----------------
|
|
|
|
- File attributes. When downloading essentially a Unix distribution,
|
|
some of the file attributes may not be correct... especially those
|
|
in the [.VMS] subdirectory. In EDT you could see line feeds and
|
|
carriage returns as <LF><CR> etc. To correct this use the command
|
|
|
|
$ set file <filespec> /attr=rfm=stm
|
|
|
|
This sets the record format to be "stream". Other variants may be
|
|
used instead depending on how you got the files onto your system.
|
|
Files will look okay in an EDT editor once the attributes are set.
|
|
Without this the command file may not run correctly, since it may
|
|
be interpreted as a single line.
|
|
|
|
- VMS-specific files are in a [.VMS] directory. If you've found
|
|
this file then you already know this :-) This directory contains
|
|
|
|
BUILD_XSLT.COM - a build command file
|
|
README.VMS - these notes
|
|
|
|
- Don't execute BUILD_LIBXML.COM until you've done all the
|
|
following
|
|
|
|
- read these notes
|
|
- define the logicals XMLOLB and LIBXML
|
|
- copy CONFIG.H to [.libxslt] and [.libexslt]
|
|
- reviewed the configuration section of BUILD_XSLT.COM, and in
|
|
particular update the module lists in line with MAKEFILE
|
|
- re-read these notes :-p
|
|
|
|
instructions for all these steps are below.
|
|
|
|
- the XSLT package requires the LIBXML package to have been
|
|
previously been installed. The following logicals should be
|
|
defined
|
|
|
|
LIBXML - the directory containing LIBXML's .h files
|
|
XMLOLB - the directory to contain both the LIBXML and XSLT
|
|
object libraries
|
|
|
|
- you'll need to copy config.h into the [.libxslt] and [.libexslt]
|
|
directories. If in the future a VMS-specific version is created,
|
|
use [.vms]config.vms instead.
|
|
|
|
- The command file BUILD_XSLT.COM will do the following
|
|
|
|
- setup and test some logicals
|
|
- set def to the source directory
|
|
- compile modules and place them into a LIBXSLT.OLB library
|
|
- compile modules and place them into a LIBEZSLT.OLB library
|
|
- compile and link the XSLTPROC program
|
|
- set def back to the original directory (i.e. if it fails you
|
|
might not be where you started :-)
|
|
|
|
before running this command file review the configuration segment
|
|
at the top. In particular compare the lists of modules with those
|
|
in the most recent version of MAKEFILE.IN files sound in the source
|
|
directories. Instructions are contained in the command file itself.
|
|
|
|
|
|
The TRIO package
|
|
----------------
|
|
- The libxml package uses a sub-package TRIO to provide some
|
|
functions not naturally available under VMS. These include support
|
|
for infinite and undefined numbers, and specialised print functions
|
|
like "snprintf"
|
|
|
|
To build this software we need to add
|
|
|
|
/IEEE_MODE=UNDERFLOW_TO_ZERO/FLOAT=IEEE
|
|
|
|
to the compile command for xsltutils, and to any main program
|
|
that uses this functionality. BUILD_XSLT.COM should do this
|
|
for you.
|
|
|
|
Without this you are likely to get run-time errors like this
|
|
|
|
%SYSTEM-F-HPARITH, high performance arithmetic trap, Imask=00000000,
|
|
Fmask=00000 400, summary=02, PC=000000000006A330, PS=0000001B
|
|
-SYSTEM-F-FLTINV, floating invalid operation, PC=000000000006A330,
|
|
PS=0000001B
|
|
|
|
If this occurs you'll need to locate the modules that need the
|
|
above switches applied
|
|
|
|
|
|
Compiler and linker errors
|
|
--------------------------
|
|
|
|
- with respect to the TRIO package you'll get the error
|
|
|
|
"no main module for UNDERFLOW_TO_ZERO"
|
|
|
|
You can suppress this "expected" messages by using the compile command
|
|
|
|
$ CC /WARN=DISABLE=(NOMAINUFLO)
|
|
|
|
- the Linker will report the following error
|
|
|
|
%LINK-W-MULDEF, symbol DECC$STRERROR multiply defined
|
|
in module DECC$SHR file SYS$COMMON:[SYSLIB]DECC$SHR.EXE;5
|
|
|
|
This is complaining that DECC$STRERROR is multiply defined, which
|
|
in turn is because this system symbol is getting added to LIBXML.OLB
|
|
when strio.c was compiled in the libxml package.
|
|
|
|
I'm not sure what the solution for this is, but this is a fairly
|
|
benign error.
|
|
|
|
|
|
Changes made to the codebase
|
|
----------------------------
|
|
|
|
- In the module extensions.c the name
|
|
|
|
xsltExtModuleElementPreComputeLookup
|
|
|
|
is too long (more than 31 characters). The solution has been
|
|
to rename it to a shorter name on VMS builds, and to then
|
|
create a #define that maps the longer name to the shorter name,
|
|
so that all references to the longer name will work.
|
|
|
|
You may need to repeat this exercise with any future modules added.
