Configure one compilation Create a custom compilation Use Java sources in JVM compilations Configure interop with native languages Compilation for Android Compilation of the source set hierarchy Build final Strings in Kotlin Receive C string bytes from Kotlin Fix the Code Next steps Create an app using C Interop and libcurl – tutorial Before you start Create a definition file Add interoperability to the build frequencies, stopwords, stemming, and much more. Java libraries Since Kotlin provides first-class interop with Java, you can also use Java libraries for data science in your Kotlin code. Here are some examples

} } } } 用于 C 语言互操作隐式整数转换的编译器选项 We have introduced a compiler option for C interop that allows you to use implicit integer conversions. After careful consideration, we've introduced value = 1, toDate = today, options = 0 ) To use implicit conversions with native interop libraries, use the - XXLanguage:+ImplicitSignedToUnsignedIntegerConversion compiler option. You introduces several performance and size-related optimizations, along with updates in JavaScript interop. 尺寸相关的优化 Kotlin 1.9.0 introduces significant size improvements for WebAssembly (Wasm) projects
