[csw-maintainers] problems with symbol version script

[Ben Walton]

Hi All,

I'm trying to build an updated libxslt which has, since the last
release, added a symbol version script.  The build fails with:

libtool: link: /opt/studio/SOS12/SUNWspro/bin/cc -G -h libxslt.so.1 -o

gmake: *** [libxslt.la] Error 1

So far, I've been able to make the build work by either removing the
-Wl,-M -Wl,-./libxslt.syms parameters, thus disabling the symbol
versioning completely or by added -Wl,-B -Wl,local to the arguments,
thus changing the intended behaviour of the symbol map (all symbols in
the map are defined in the global scope).

The symbol version script looks ok[1] to me.

Has anyone hit this before?  I'd prefer to enable the functionality if
possible since that makes for better .so files...

Any and all help is appreciated.

Thanks

[1] I'll be submitting a patch upstream to correct the names...looks
    like a copy error from libxml2.  They build the .syms file from an
    xml document and an xslt transform file where the transform file
    contains the LIBXML2 tags presumably as they were pulled in from
    that twin project.
