Question

我正在尝试将Kotlin / Native项目链接为iOS框架。 Kotlin代码可以正常编译，但是运行链接器时，出现以下错误：

Undefined symbols for architecture x86_64:
  "_kfun:kotlinx.coroutines.AbstractContinuation.getResult$kotlinx-coroutines-core-native()kotlin.Any?", referenced from:
      _kfun:io.ktor.client.engine.ios.IosClientEngine.execute(io.ktor.client.call.HttpClientCall;io.ktor.client.request.HttpRequestData)io.ktor.client.call.HttpEngineCall in combined.o
ld: symbol(s) not found for architecture x86_64
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld invocation reported errors

我尝试将平台从iosX64更改为iosArm64，但是会导致相同的错误。这是我的gradle文件，以防万一我缺少依赖项。

// make sure all Gradle infrastructure exists (gradle.wrapper, gradlew).
task copyFramework {
    def buildType = project.findProperty("kotlin.build.type") ?: "DEBUG"
    def target = project.findProperty("kotlin.target") ?: "ios"

    doLast {
        def srcFile = kotlin.targets."$target".compilations.main.getBinary("FRAMEWORK", buildType)
        def targetDir = getProperty("configuration.build.dir")
        copy {
            from srcFile.parent

任何帮助将不胜感激，谢谢！

您的public class SimpleRouteBuilder extends RouteBuilder { @Override public void configure() throws Exception { from("file:C:/inputFolder?noop=true").to("streamEndPoint"); } } Ktor依赖性似乎不对。尝试这样设置：

iosMain

链接ktor和kotlinx.coroutines导致未定义符号
