[xsd-users] OS-defined type names conflict with schema type names

[Dave Simonson]

   Trying to map a large schema, the code generation seems to go well:

   $  xmllint --noout UCSM-IN.xsd

   $ cat xsd_opts.txt

   cxx-tree

   --output-dir /cygdrive/d/UCS_Xfer/schema_4.1.2/src

   --std c++11

   #--generate-inline

   --generate-dep

   --show-sloc

   --generate-ostream

   --generate-doxygen

   --generate-polymorphic

   --generate-wildcard

   --polymorphic-type anyType

   --custom-type timezone=timezone_xs

   --custom-type clock=clock_xs

   --custom-type select=select_xs

   #--parts 40


   $ xsdcxx --options-file xsd_opts.txt UCSM-IN.xsd

   The compile has problems with types with names that match OS-header
   defined types, even though I've tried to rename them (I think) with
   -custom_type.

   I'm using:

   gcc version 10.2.0 (GCC)

   CodeSynthesis XSD XML Schema to C++ compiler 4.0.0


   What have I missed? This can't be that uncommon, but I haven't found
   anything in the archives or documentation. Any suggestions?
