[xsde-users] XSDE Compilation error : longlong and nolonglong option in the XSDE build

Hello,

I am from Trixell project, Thales India PVT LTD. We are using xsde to generate source code from xml files in our software.
I am currently working with multiple XSD schemas that are being processed using different XSDE generation options. Specifically, one schema (Rev32_SIF.xsd) is generated with the --no-long-long flag,
while another schema (Rev00_IMG.xsd) requires full long long type support as below

"
set xsde_options=cxx-hybrid --generate-parser --generate-aggregate --no-long-long --show-sloc --proprietary-license --prologue-file *=trixell-license.txt
set xsde_options_storage_date=cxx-hybrid --generate-parser --generate-aggregate --show-sloc --proprietary-license --prologue-file *=trixell-license.txt

bin\xsde.exe %xsde_options% --generate-serializer --namespace-map =Rev32_SIF  Rev32_SIF.xsd
bin\xsde.exe %xsde_options_storage_date% --generate-serializer --namespace-map =Rev00_IMG  Rev00_IMG.xsd
"

During compilation, I am encountering conflicting typedef declarations originating from txl_types.hxx, such as:

./ComponentApp/Gen3_coreapps/CommonLibs/GEN3_CMLIB/Misc/XmlParser/txl_types.hxx:69:25: error: conflicting declaration 'typedef long unsigned int xml_schema::unsigned_long'
   69 |   typedef unsigned long unsigned_long;

      |                     ^~~~~

I would like to confirm whether this is a known limitation with mixed XSDE runtimes and whether using --namespace-regex to isolate the XML Schema runtime (e.g. --namespace-regex xml_schema=xml_schema_img) is the recommended solution.
Could you please advise on the following:

  1.  Is namespace separation the preferred method to prevent such typedef collisions?
  2.  Are there any best practices or examples available for handling multiple XSDE-generated schemas with different integer type configurations?
