Sounds as if you've got a .so name clash - what does
running 'ldd' on the generated PcreStub.so / Pcre.so
report? i.e., what's the name of the _real_ .so that
contains the PCRE lib?If it's also called Pcre.so,
you'll need to rename to let the loader distinguish
between it and the Hugs98 extension module.
Re: PcreStub.so vs Pcre.so - as you suspected, it's
supposed to be the latter. Fixed in my dev copy of
HDirect.
