Kotlin/Native

Kotlin/Native is a LLVM backend for the Kotlin compiler, runtime implementation and native code generation facility using LLVM toolchain.

Kotlin/Native is primarily designed to allow compilation for platforms where virtual machines are not desirable or possible (such as iOS, embedded targets), or where developer is willing to produce reasonably-sized self-contained program without need to ship an additional execution runtime.

To compile from sources use following steps.

First download dependencies:

./gradlew dependencies:update

Then build the compiler and standard library:

./gradlew dist

To build standard library for cross-targets use:

./gradlew cross_dist

After that you should be able to compile your programs like that:

export PATH=./dist/bin:$PATH
kotlinc hello.kt -o hello

For an optimized compilation use -opt:

kotlinc hello.kt -o hello -opt

For some tests, use:

./gradlew backend.native:tests:run

To generate interoperability stubs create library definition file (take a look on samples/tetris/.../sdl.def) and run cinterop tool like this:

cinterop -def lib.def

See provided samples and INTEROP.md for more details.

Interop tool generates library in .klib library format, see LIBRARIES.md for more details on the file format.
