Protocol Buffer as XCode Framework

[Carlos Gamboa]

Hello. I am trying to add the protocol buffer to my application (for
iphone) and i have been struggling for about 2 days to figure out how
to do it. I am new to XCode too by the way. I tried creating a
framework like Brian Olson suggested on this post:
http://groups.google.com/group/protobuf/browse_thread/thread/65e781a5e8d6fc06#
, but i do not know all the things i need to include this framework.
Here are the steps im following.
1. Compile the protobuf project
2. On my project, right click on Frameworks and click 'add->existing
frameworks' and then locate the 'macosx/build/release/
protobuf.framework' folder. The framework is located at the documents
folder (documents/macosx)
3. I created my .pb.h and .pb.c with the 'protoc' program and added
them to my project.
4. I try to compile, but the following 18 errors appear like this:
"google::protobuf::UnknownFieldSet::UnknownFieldSet()", referenced
from:
myNamespace::myProto::myProto() in myProto.pb.o
...

I really dont care if i add it as a framework or as direct code, but i
have not been able to include the protocol buffer as part of my
project. Can anyone please help me?

I'm not sure how mac frameworks work, but it looks like your compiler is not linking against the protobuf library.

Were you finally able to use protocol buffers in your iphone
application ?

Carlos,

In which program is your project written? Is it Objective-C?

Probably your problem isn't on linking the library itself... if your
project is written in Objective-C remember that linking with C++ code
requires a .mm extension for your Objective-C code!

Give it a try ;)

also realize that frameworks you create won't work with the iphone --
you need to create a static library.
