Kotlin-OHOS

Kotlin native support for OpenHarmony OS and HarmonyOS

HarmonyOS Beta1刚出的时候，抽了一点时间适配了HarmonyOS的native target，没什么时间继续搞太多，抛砖引玉啦。 仓库有点多，源代码还要整理下

食用方法

目前prebuilt的都是基于HarmonyOS Beta1的command-line-tools进行编译的，在beta1上测试了一切正常，其他版本自行尝试。 宿主机是M系列的电脑，x86 mac和windows/linux暂时没加支持，支持也简单，就是没时间

1. 去官网下载command-line-tools工具，或者已经下了DevEco-Studio也可以，将HarmonyOS的SDK的路径映射到~/.konan/目录下，没有这个目录就创建，最终的目录像这样 /Users/用户名/.konan/HarmonyOS-NEXT-DB1

2. 解压kotlin-native-prebuilt-macos-aarch64-2.1.255-SNAPSHOT.tar.gz文件到~/.konan/目录下，最终的目录像这样 /Users/用户名/.konan/kotlin-native-prebuilt-macos-aarch64-2.1.255-SNAPSHOT

3. 新建KMP Library工程，在settings.gradle仓库添加本地仓库地址，解压repo仓库，比如解压到Download文件夹了，那么就是

pluginManagement {
    repositories {
        maven {
            url = uri("/Users/用户名/Downloads/repo")
        }
        mavenLocal()
        google()
        gradlePluginPortal()
        mavenCentral()
    }
}

dependencyResolutionManagement {
    repositories {
        maven {
            url = uri("/Users/用户名/Downloads/repo")
        }
        mavenLocal()
        google()
        mavenCentral()
    }
}

3. 修改依赖版本，改成本地的snapshot版本

[versions]
kotlin = "2.1.255-SNAPSHOT"
kotlinxCoroutinesCore = "1.9.0-RC.2-SNAPSHOT"
kotlinxDatetime = "0.6.1-SNAPSHOT"
kotlinxIo = "0.6.0-SNAPSHOT"
kotlinxSerialization = "1.7.3-SNAPSHOT"
atomicfu = "0.25.0-SNAPSHOT"`

[libraries]
kotlinx-coroutines-core = { module = "org.jetbrains.kotlinx:kotlinx-coroutines-core", version.ref = "kotlinxCoroutinesCore" }
kotlinx-io-core = { module = "org.jetbrains.kotlinx:kotlinx-io-core", version.ref = "kotlinxIo" }
kotlinx-io-bytestring = { module = "org.jetbrains.kotlinx:kotlinx-io-bytestring", version.ref = "kotlinxIo" }
kotlinx-datetime = { module = "org.jetbrains.kotlinx:kotlinx-datetime", version.ref = "kotlinxDatetime" }
kotlinx-serialization-core = { module = "org.jetbrains.kotlinx:kotlinx-serialization-core", version.ref = "kotlinxSerialization" }
kotlinx-serialization-json = { module = "org.jetbrains.kotlinx:kotlinx-serialization-json", version.ref = "kotlinxSerialization" }
kotlin-atomicfu = { module = "org.jetbrains.kotlinx:atomicfu", version.ref = "atomicfu" }
androidx-core-ktx = { group = "androidx.core", name = "core-ktx", version.ref = "coreKtx" }

4. shared模块build.gradle中添加harmonyOS target，如

    harmonyOSArm64 {
        binaries.sharedLib {
            baseName = "hellokt"
        }
    }

5. 在gradle task里构建，或者命令：

./gradlew shared:linkHarmonyOSArm64

Build成功的话，在shared/build/bin/harmonyOSArm64目录下会出现so文件和.h文件，可以在arkts中通过npai直接调用

注意，由于kotlin cinterop的要求，宿主机需要安装aarch64的Azul Zulu JDK8，详细可以去kotlin官方仓库查看
