building XML-0.95-1 on MacOS
Hi Sean. Two things. There is a new version of the XML package now on the Omegahat web site: http://www.omegahat.org/RSXML/XML_0.95-3.tar.gz That uses a different approach to dealing with errors and avoids having to redefine the xmlParserError() routine. As a result, one should not need the -m flag. Secondly, unless there are good reasons for using libxml-1.8.*, it is preferrable to use the libxml2-2* series. The configuration for this version of the XML package has been "upgraded", but may require some assistance. If it doesn't compile out of the box, please set the environment variable XML_CONFIG to the name of the xml-config or xml2-config script that provides the relevant information. I'll fix this up in the next release. D.

I am trying to build the XML package on MacOS. I am using the fink installation of libxml-1.8.17. The configuration information is: Configuration information: Libxml settings libxml include directory: /sw/include/gnome-xml libxml library directory: -L/sw/lib -lxml -lz -lz -lxml libxml 2: no Compilation flags: -I/sw/include/gnome-xml -I/sw/include/gnome-xml/libxml -DLIBXML -I/sw/include/gnome-xml Link flags: -L/sw/lib -lxml -lz -lz -lxml Compiling produced the following error: gcc -bundle -flat_namespace -undefined suppress -L/sw/lib -L/usr/local/lib -o XML.so DocParse.o EventParse.o ExpatParse.o HTMLParse.o RSDTD.o RUtils.o Utils.o XMLEventParse.o XMLTree.o -L/sw/lib -lxml -lz -lz -lxml -lcc_dynamic ld: multiple definitions of symbol _xmlParserError Utils.o definition of _xmlParserError in section (__TEXT,__text) /sw/lib/libxml.dylib(error.lo) definition of _xmlParserError make: *** [XML.so] Error 1 ERROR: compilation failed for package 'XML' I saw that back in September there was a discussion about fixing this problem that involved passing -m to the linker. My questions are (1) what do I need to modify (given that I am using R INSTALL to keep things simple for myself) to use the -Xlinker -m option when linking XML.so and (2) does this actually work despite the fact that there are then two definitions associated with the same symbol? I guess a third question follows from the second--are there other fixes that I can use to build the package? Thanks in advance, Sean
