Re: [xslt] undefined reference to `xmlXPathContextSetCache'

ELF shared libraries were never intended to have a so.N.M denominator, solely
a so.N one. So in the above I would sooner expect:

libxml2.a
libxml2.la (libtool specific file)
libxml2.so.8
libxml2.so.9
libxml2.so -> libxml2.so.9

You need to have a libxml2.so file, typically this is symbolically linked to
the latest installed shared library. If I remember my loading and linking
correctly ELF looks for the libxml2.so file for loading and linking.

Ok, so I created the symlink (and indeed you're right, since I know *nix OSes, there are always such symlinks) :

root myhost:/usr/local/lib # ln -s libxml2.*
libxml2.a         libxml2.la        libxml2.so.8.27   libxml2.so.9.0
root gages:/usr/local/lib # ln -s libxml2.so.9.0 libxml2.so
root gages
:/usr/local/lib # ls -la |grep xml
-rw-r--r--   1 root  wheel  5284726 Jan  5 10:35 libxml2.a
-rwxr-xr-x   1 root  wheel      805 Jan  5 10:35 libxml2.la*
lrwxr-xr-x   1 root  wheel       14 Jan  5 13:52 libxml2.so
@ -> libxml2.so.9.0
-rwxr-xr-x   1 root  wheel  2981560 Jan  5 10:35 libxml2.so.8.27*
-rwxr-xr-x   1 root  bin    1112822 Mar  1  2006 libxml2.so.9.0*
-rw-r--r--   1 root  wheel      219 Jan  5 10:35 xml2Conf.sh

Then again, ./configure, make clean, make, and same error :

Another point :

$ strings /somefolder/libxslt-1.1.17/libxslt/.libs/libxslt.so.2.17 | grep xmlModuleClose
xmlModuleClose

So I don't know if the presence of the string does prove anything, but ... ?
