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 a developer is willing to produce a reasonably-sized self-contained program without the 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 libraries:
./gradlew bundle
The build can take about an hour on a Macbook Pro. To run a shorter build with only host compiler and libraries run:
./gradlew dist distPlatformLibs
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.
