avrogencpp and multiple .avsc
Is it possible to generate code for multiple schemas at one time, and
resolve references between them? I tried using an avpr file, and it did not
seem to like that.
thanks,

Yes, as far as I can tell, the avdl format is not supported in by
avrogencpp it only takes json schema. Sad, but true.

The java-based command line tools can be used to convert .avdl files
into .avsc and .avpr files that can then be used for code-generation
using the C++-specific tools. A separate .avdl compiler for C++ is
not needed.

Thanks,
I was specifically looking for code generators for c++. It looks like the
avdl format is not supported at all in that implementation?

The command line 'compile' tool and maven task both support this. One
can pass multiple schema files on the command line, and each can
reference schemas that precede it on the command line.
With Maven, you can specify imports. See
https://issues.apache.org/jira/browse/AVRO-1188 for details.

With a .avpr file you can place multiple schemas in its "types"
section, leaving the messages section empty.
With an .avdl file you can import other .avsc, .avpr and .avdl files.
