mulle-clang, technically speaking

The mulle-clang compiler is a variant of the clang compiler. The clang compiler has built-in support for a variety of Objective-C runtimes, such as

• MacOSX
• FragileMacOSX
• iOS
• WatchOS,
• GCC
• GNUstep
• ObjFW

mulle-clang adds another runtime Mulle. Mulle is a variant of FragileMacOSX. Ideally mulle-clang is a superset of the clang compiler, being able to also compile Objective-C code for the other platforms. But that is currently NOT possible.

In order to compile an Objective-C file (.m), you need the runtime mulle-objc-runtime and the mulle-clang compiler. Both are built using a shell script install-mulle-clang.sh.

Required Toolset

The toolset requirements for the compiler itself are not any different from those of clang. Building mulle-clang by hand can be a bit daunting, but install-mulle-clang.sh should make the build painless.

bash

bash is needed for the installation script.

git

git is used to retrieve mulle-clang.

cmake (make)

cmake is a cross-platform Makefile generator. It is used by mulle-clang and llvm.

gcc/clang

A standard C compiler is needed to compile mulle-clang and *llvm.

Required Libraries
