iOS 5 , Xcode 4.2 and ProtoBuf

Question

I'm trying to compile google protobuf protocol for using it in my iOS 5 project, but with no success yet... I found only one blog post about the topic here. But when I try this method I receive error:

h-3.2# make
make all-recursive
Making all in .
make[2]: Nothing to be done for `all-am’.
Making all in src

I have worked old project with protobuf but it is created in xcode 3.x. Is there a way or some tutorial how to use it in xcode 4.2 and armv7 architecture? I lose 2 days of my project time to research the problem and still no success... My project deadline is soon and I have no chance to proceed without this protobuf...

Answer 1

This blog post gives the instructions on how to compile the protobuf library with armv7, armv7s, i386 architectures for iOS. There is also a link in the blog post to download a precompiled iOS library for protobuf that works on the device as well as the simulator.

Have you tried using Objective-C protocol buffers?
