[xsd-users] RE: [xsde-users] how to handle xsd:include?

[Gennady Khokhorin]

Boris,
thanks for pointing to the right place for this discussion.

Still getting compilation errors like: error C2039: 'myType' : is not a
member of '`global namespace'' 
and c2504 'myType' :base class undefined

Did try both approaches:
1. including main.xsd (myType declared here) in sect01.xsd:<xsd:include
schemaLocation="main.xsd"/>
just before myType declaration. main.xsd has the same include:
<xsd:include schemaLocation="sect01.xsd"/>
2. using --file-per-type option for main.xsd only. This produced double
declarations for otherTypes in sect01.hxx 
and in otherType.hxx

For instance in case 1 myType (see sample below) declared as:
main.hxx:
class myType;
..
class myType: public ::xml_schema::String
{..}

sect01.hxx:
#include <main.hxx>
class otherType;
..
class otherType: public ::myType // error c2504: 'myType' base class
undefined

Command line looks like:
xsd.exe cxx-tree --generate-intellisense --generate-serialization
--type-naming ucc  --function-naming lcc --root-element-all main.xsd
xsd.exe cxx-tree --generate-intellisense --generate-serialization
--root-element-all sect01.xsd

Please, let me know what other options I should try.
Thanks in advance.
Gennady

Hi Gennady,

You have sent your questions to the wrong mailing list again. Please
send questions about CodeSynthesis XSD to the
xsd-users at codesynthesis.com mailing list, not to xsde-users.

It appears that your sect01.xsd does not include/import all the type
definitions that it uses and as a result it is not valid by itself. You
have two options:

1. Fix sect01.xsd to include all the necessary schemas so that
   it becomes self-sufficient.

2. Use the file-per-type compilation mode that was introduced
   in XSD 3.1.0. In this mode the compiler will generate a
   set of source files for each XML Schema type. To use this
   mode you will invoke the compiler like so:

   xsd.exe cxx-tree --file-per-type main.xsd

   Note that in this mode you won't need to compile sect01.xsd
   or any other schema that main.xsd may import or include
   separately.

   For more information about the file-per-type mode, please
   see the following blog post:
