此贴用于记录对Kotlin Native从初识到放弃的过程，因为还不清楚这一平台的开发能力上限多高，不排除用的好，会一直用下去。 以下Kotlin Native会用KN来代替。

开始

首先，下载IDEA，我这里用的是社区版，社区版已经足以应对大多数情况了。 然后，新建一个KN的项目。 kotlin-native-start.jpg IDE会自动生成hello world代码，直接点运行，如果工具栏的运行按钮没有可执行的配置，那就直接在Main.kt文件上右键运行。相比直接用Clion写C/C++代码的运行速度，KN项目运行要慢得多，因为要先执行gradle脚本。 即便是这样，你也很可能第一次运行不成功，在macOs上，要安装XCode command line tools工具，我这里直接安装了完整版的XCode。 然后继续尝试运行，你很可能会发现，依然执行不成功，报如下错误：

The /usr/bin/xcrun command returned non-zero exit code: 72

这时候，你需要打开XCode，执行一系列同意操作后，进入Preferences -> Locations，选中一个版本。如下： xcode-select 如果你没有安装完整XCode，可以尝试xcode select这个命令，这里具体不做详述。 经过这个设置后，再次尝试运行，这次终于运行成功。

请在上述输出日志中寻找Hello, Kotlin/Native字符串，很不起眼。
