scala-native-example

A minimal Scala Native example that calls a C function (https://github.com/scala-native/scala-native)

About the example

  • The project contains two source code files, main.scala and stub.c
  • Main.scala will call a function in stub.c
  • The stub.c function writeFile called from Scala will write a file in the current working directory

About the build process

  • The scala native plugin is added in the project/plugins.sbt file
  • build.sbt runs the makefile, producing the shared library in the \target directory
  • A custom library path is added to nativeLinkingOptions so the stub library can be found
  • Compile & run with sbt run
  • The resulting native executable can be found in target/scala-2.11

Requirements

  • 64 bit Linux based OS
