控制台执行 testnative.exe 会输出 hello native。
到这里就配置完成可以正常使用了。
4. 总结
我在安装过程中主要遇到下面3个问题：
安装VS CODE 2019工具时要使用默认路径，更改路径会导致找不到 bat 脚本，无法运行。
使用官方文档链接下载的 vs_buildtools__9e116ae0599f413e8e5d9edd8a3e7929.exe，这个工具安装的 VS CODE 2019 版本，安装的 cl.exe 版本低，会报下面的错误：
1 2
Error: On Windows, GraalVM Native Image for JDK 21 requires Visual Studio 2022 version 17.1.0 or later (C/C++ Optimizing Compiler Version 19.31 or later). Compiler info detected: cl.exe (microsoft, ??, 19.29.30153)
解决办法就是安装 VS CODE 2022版本，这个版本的 cl.exe 版本如下：
第2个问题就是 **Error: Native-image building on Windows currently only supports target architecture: AMD64 (?? unsupported)**，这个问题搜到了 github 上的 Issues，按照里面的操作选择英文语言就可以了。问题的原因可能是因为不支持中文，导致获取操作系统类型时出现了乱码。这一步使用普通的 CMD 也可以执行命令，关键的地方在于语言包。
