[xsd-users] xs:double truncation

[Aaron Bray ARA/SED]

Ok, I figured it out, I am not sure how this works (there is explanation
on your wiki, but it still hurts my head...)

xsd.exe cxx-tree --generate-serialization --generate-ostream
--generate-default-ctor --custom-type double=double --custom-type
"decimal=long double" --hxx-epilogue-file xml-schema-epilogue.hxx
--export-symbol __declspec(dllexport) --extern-xml-schema nucs-schema
--generate-xml-schema nucs-schema


I was not using the --generate-xml-schema command to generate the file
--extern-xml-schema wanted
It may be worth adding these two commands to your earlier referenced zip
example README in the compile options

All is well

Thank you for the help!

Aaron Bray

The double.hxx file shouldn't be included by the generated code
if you are customizing the xsd:double and xsd:decimal types. I
think one of the two things happen:

1. You don't have the following options when generating xml-schema.hxx
   (in which case double.hxx will be included by xml-schema.hxx)

   --custom-type double=double 
   --custom-type "decimal=long double"

2. You don't have the following option when compiling some of your
   schemas (in which case double.hxx will be included by the
   generated header files for those schemas):

   --extern-xml-schema xml-schema.xsd

Can you check if any of this is happening? If not, can you search
the generated code to see which file(s) include double.hxx?
