Re: Xerces-P with HPUX11

["Jason E. Stewart" <ja...@openinformatics.com>]

Hey Uwe,

You can't mix libraries compiled with different C++ compilers. There
is no standard interface, so they all produce differently named
symbols. To use the Xerces-C HP binary, you'll have to compile
Xerces-P with aCC, otherwise you'll have to recompile Xerces-C with
g++.
