[xsd-users] error processing multiple schemas at once

[Eric Broadbent]

Hi Boris,
when I built XSDE, many serialization files were built - whether or not I set  "XSDE_SERIALIZER_VALIDATION" on or off in config..make
(Here's a partial listing of the compiles with XSDE_SERIALIZER_VALIDATION := n")

	g++  -I.. -W -Wall -O3 -c cxx/serializer/elements.cxx -o cxx/serializer/elements.o
	g++  -I.. -W -Wall -O3 -c cxx/serializer/context.cxx -o cxx/serializer/context.o

I was operating with the understanding that serialization is optional - but perhaps that's only when schema-compilation is run (after XSDE is built).
The chapter on Serialization (http://www.codesynthesis.com/projects/xsd/documentation/cxx/tree/manual/#4) indicates:

"Note that the generation of the serialization code is optional and should be explicitly requested with the --generate-serialization option."

Secondly, in the software that XSDE will be linked into, Expat exists already.
Instead of having the XSDE build process compile another instance of Expat, is it possible for me to just point the XSDE library at the existing build?
(Assuming they are the same release of Expat which they are)

Thanks again for your help - sorry for all the questions.

-Eric
