Re: [protobuf] Circular package import problem
With protoc (the standard compiler), this should produce a simple error. Since Ken said he "got StackOverFlow exception", it sounds like he's using some other compiler (not written in C++).

Re: [protobuf] Circular package import problem
You probably need to break up your proto files to eliminate the circular dependency.. (i.e. have multiple .proto files for a package, and only import necessary .proto files).

[protobuf] Circular package import problem
Hi, I have two proto files: A.proto and B.proto. If I import package B in A and import A in B, I got StackOverFlow exception during compiling. Does anyone know any sulotion for it?

This needs to be:
optional modules.diagnostics.DiagnosticsConfig set_diagnostics_config = 8;

import problem
Hello,
I have defined the following messages:
package myapp.proto.modules.diagnostics;
message DiagnosticsConfigMessage {
optional bool watchdog_enabled = 1;
optional uint32 watchdog_timeout = 2;
}
package myapp.proto;
import "src/myapp/proto/modules/diagnostics/DiagnosticsConfig.proto";
message ViewServerMessage {
...
optional DiagnosticsConfig set_diagnostics_config = 8;
...
}
The first message is in src/myapp/proto and the second is in src/myapp/
proto/modules/diagnostics
When I try to compile Java classes with
c:\users\myname\bin\protoc.exe --proto_path="C:\projects\MyApp.root
\MyApp" --java_out "C:\projects\MyApp.root\MyApp\build\generated-
sources\protobuf-java" "C:\projects\MyApp.root\MyApp\src\myapp\proto
\ViewServer.proto"
I always get an error message:
src/myapp/proto/ViewServer.proto:20:14: "DiagnosticsConfigMessage" is
not defined. How is it possible to include a message defined in a
subdirectory? Defining all messages in the same namespace would work,
but it is quite ugly and I would like to avoid this if possible.
I am using protoc.exe 2.0.3 on Windows.

Re: Recursive import problem
Sorry, but mutually recursive messages must be declared in a single file.
It would be excessively complicated to support cyclically dependent files
under the current implementation.

Recursive import problem
I have the following message structure:
===A.proto===
message A
{
optional B1 b1 = 1;
}
message B1
{
optional A a = 1;
}
Everything works as intended when the messages are in the same file.
However, in my situation there are several child messages (B2,
B3, ...) which all naturally all go in their own separate files
(B2.proto, B3.proto, ...). Unfortunately, B1 cannot go in its own file
due to a problem with a recursive import.
Is there any way to solve this? Can I "forward declare" messages?
Thanks,
Justin
