[protobuf] Compiling .proto files with scons
Sorry if this is a bit of a newbie question, but I'm new to both protobuffers and scons. What's the easiest way to get .proto files to compile to .pb.cc and .pb.h files? I know you guys use scons at google, so I'm hoping that there's a cut-and-paste solution - but if now, can someone recommend where to look to figure it out? -- You received this message because you are subscribed to the Google Groups Protocol Buffers group.

Re: [protobuf] Compiling .proto files with scons
Sorry, I thought I had read in an interview somewhere that you guys were using scons internally. And I actually can get scons to run protoc, I'm just having trouble getting it to read the .proto files from the right source directories and write the .pb.cc and .pb.h files to the right build directories. If there's not a cut-n-paste solution that folks here know about, I'll move this question to a scons discussion group.

We mostly use an in-house build system full of Google-specific hacks -- like how to build protocol buffers. But it can't be that hard to get scons to run a shell command, can it?

Re: [protobuf] Compiling with Debug
Thanks for your help - I found that I was exceeding the recursion limit in CodedInputStream. I was able to instantiate my own CodedInputStream and increase the limit, but it would be nice if some sort of error was printed when the limit is exceeded.

You'll probably find that they are different in some way, which will point you towards the problem.

Re: [protobuf] Compiling with Debug
I understand why it's there, and it makes sense for apps in general. I admit I'm using proto bufs for general serialization purposes within my app rather than the over-the-wire communication tool it was designed as. It just seems much easier to use than boost::serialization or other alternatives. What I was serializing in this case was a tree that had more than 64 levels, so yeah the data was legitimate. Do you recommend a different library for general purpose serialization?

That said, you're the first person I've ever heard of who hit that limit with (presumably) legitimate data. Consider designing you protocol differently? The limit exists for security reasons (to avoid stack overflows), so simply bumping it up isn't the best solution (though you can probably increase it significantly before running any real risks).
