How do I write and compile Objective-C code?

Question

How do I write and compile Objective-C code in Linux?

I heard about Clang, but I couldn\'t find any example/tutorial about Clang/LLVM/Objective-C.

Answer 1

You download and build LLVM as the compiler infrastructure; then you download and build the CLANG front-end to compile C/C++ and Objective C/C++.

I guess you could try following this quick start guide. Mind that Clang could actually replace GCC when working with these languages.
