Hi,
I made a previous post last July, about porting Libxml2-2.9.4 code in order to
be able to compile and run it on zOS, but I had no return...
I build on the USS partition of the zOs server and build successfully using
configure and make as I would on Linux... I attached the difference in order to
patch libxml...
I also had to make some (mandatory) modifications to the Makefile.in file:
therefore I also attach a file describing the problems I ran into and how I
solved it and what could be made in order
to make it simplier to use :)
Don't hesitate to ask me if it is not clear or if you have any suggestions.
Best regards,

- since testapi.c file is huge (over 52000 lines), it's compilation fails: I
skipped the problem by removing all references to testapi in the Makefile.in,
but it would be neater if one can build without test files (I didn't find an
option in configure...)
- since the name of files (or qualifier) in PDS are limited to 8 I had to
rename xmlschemas.c and xmlschemastypes.c in (resp.) xmlsche.c xmlschet.c
(and I had to modify all occurences of these files accordingly in the rest of
the Makefile !!!).
- in order to copy objects to PDS, I had the cp command at line 860 of
Makefile.in
libxml2.la: $(libxml2_la_OBJECTS) $(libxml2_la_DEPENDENCIES)
$(AM_V_CCLD)$(libxml2_la_LINK) -rpath $(libdir) $(libxml2_la_OBJECTS)
$(libxml2_la_LIBADD) $(LIBS)
# Copy objects to PDS
@list='$(libxml2_OBJECTS)' ; for p in $$list; do \
cp -ACMv $$p "//'<PDS NAME>'"; \
done
with <PDS NAME> stands for the name of my PDS and
libxml2_OBJECTS = SAX.o entities.o encoding.o error.o \
parserInternals.o parser.o tree.o hash.o list.o xmlIO.o \
xmlmemory.o uri.o valid.o xlink.o HTMLparser.o \
HTMLtree.o debugXML.o xpath.o xpointer.o xinclude.o \
nanohttp.o nanoftp.o triostr.o trio.o catalog.o globals.o \
threads.o c14n.o xmlstring.o buf.o xmlregexp.o \
xmlsche.o xmlschet.o xmlunicode.o \
xmlreader.o relaxng.o dict.o SAX2.o \
xmlwriter.o legacy.o chvalid.o pattern.o xmlsave.o \
xmlmodule.o schematron.o xzlib.o
In order to handle the support of zOS without breaking the existing Makefile
maybe a new option/flag zOs would copy xmlschemas.c and xmlschemastypes.c files
and use specifics
targets rather than existing ones with the longer names... A variable to handle
the PDS name has to be provided also...
