Avro C++ Code generation error
Hi,
I am trying to generate C++ code for my avro schema file and when run precompile, then I am getting below error
"Failed to parse or compile schema: Schema is invalid, due to bad node of type symbolic"
The same schema works for Java and .Net code generators. Can you please let me know the root cause of the issue.
// Below is the schema.
{"namespace": "com.baml.gmrt.messaging.avro.writer",
"protocol" : "writer-compatible",
"doc" : "Protocol for writer-compatible",
"types" : [
{"name": "Kind", "type": "enum", "symbols": ["FOO","BAZ"]},
{"name": "MD5", "type": "fixed", "size": 16},
{"name": "MyRecord", "type": "record",
"fields": [
{"name": "kind", "type": "Kind", "order": "descending"},
{"name": "name", "type": "string", "order": "ignore"},
{"name": "longType", "type": "int"},
{"name": "floatType", "type": "long"},
{"name": "doubleType", "type": "float"},
{"name": "extra", "type": "string"},
{"name": "hash", "type": "MD5"},
{"name": "mapTest", "type": {"type": "map", "values": "Kind"}},
{"name": "unionTest1", "type": "string"},
{"name": "unionTest2", "type": ["Kind", "null"]},
{"name": "arrayTest", "type": {"type": "array", "items": "long"}}
]
}
],
"messages" : {
"A" :{
"doc" : "test long message",
"request" : [{"name": "event", "type":"MyRecord"}],
"response" : "string"
}
}
}
Thanks,
Xiaolu

Hi, I think this is because the C++ version still lacks namespace support,
so it thinks "namespace" is an undefined type.
