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...

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.
