Get started with Kotlin/Native using the command-line compiler
Obtain the compiler
The Kotlin/Native compiler is available for macOS, Linux, and Windows. It is available as a command line tool and ships as part of the standard Kotlin distribution and can be downloaded from GitHub Releases. It supports different targets including Linux, macOS, iOS, and others. See the full list of supported targets. While cross-platform compilation is possible, which means using one platform to compile for a different one, in this Kotlin case we'll be targeting the same platform we're compiling on.
While the output of the compiler does not have any dependencies or virtual machine requirements, the compiler itself requires Java 1.8 or higher runtime.
Install the compiler by unpacking its archive to a directory of your choice and adding the path to its
/bin directory to the
PATH environment variable.
Write "Hello Kotlin/Native" program
The application will print "Hello Kotlin/Native" on the standard output. In a working directory of choice, create a file named
hello.kt and enter the following contents:
Compile the code from the console
To compile the application use the downloaded compiler to execute the following command:
The value of
-o option specifies the name of the output file, so this call should generate a
hello.kexe (Linux and macOS) or
hello.exe (Windows) binary file. For the full list of available compiler options, see the compiler options reference.
While compilation from the console seems to be easy and clear, it does not scale well for larger projects with hundreds of files and libraries. For real-world projects, it is recommended to use a build system and IDE.
