Thanks for the tip on mod'ing for the pcrecpp inclusion. I did this and rebuilt (tried with both .a and .so libs). I no longer see the undef'd symbol for pcrecpp, but now get an undef'd symbol for _Z16registerDomTypesv - for both types of build. As you've posited, there is something more dubious going on. -bob >> >> ---------- Forwarded message ---------- >> Date: Fri, 30 Nov 2007 17:32:07 -0900 (AKST) >> From: Bob Huebert <[EMAIL PROTECTED]> >> Reply-To: OpenSceneGraph Users <osg-users@lists.openscenegraph.org> >> To: Roger James <[EMAIL PROTECTED]> >> Cc: 'OpenSceneGraph Users' <osg-users@lists.openscenegraph.org> >> Subject: Re: [osg-users] undefined symbol in osgdb_dae.so >> >> Thanks Roger.
