This is a fork of Kotlin programming language project, adding support of interoperability of Kotlin-JVM with Objective-C. Basically it allows to call functions of compiled Objective-C libraries from Kotlin under JVM. The project is maintained by Alexander Udalov and was presented as a graduation thesis to Saint Petersburg State University, Mathematics & Mechanics Faculty, Department of Software Engineering in 2013 under supervision of Andrey Breslav.

1. Download the project and launch Make in IDEA

2. Install protobuf 2.4.1 as a global library. A possible way to do this via Homebrew:

   cd /usr/local
   git checkout 544209f /usr/local/Library/Formula/protobuf.rb
   brew install protobuf
   

3. Make libKotlinNativeIndexer.dylib:

   cd compiler/objc/frontend.objc/native
   make
   

   Optionally, you can run Native Indexer tests:

   make tests
   

4. Make libKotlinNative.dylib:

   cd runtime/native
   ./ffi_make  # this is needed only the first time to download and build libffi
   ./make_native
   

5. Run ant dist

Now you can run tests. They are found under compiler/tests/org/jetbrains/jet/objc/. If you have trouble launching them, copy the needed environment variables and java arguments from the Obj-C Tests run configuration.
