<code>-Diotdb-tools-thrift.version=0.14.1.1-old-glibc-SNAPSHOT</code></li></ul><p>Q：如果在 Windows 上需要使用 Visual Studio 2017 或更早版本进行编译，要怎么做？</p><p>A:</p><ul><li>可以尝试自己本地编译 Thrift 后再进行客户端的编译 <ul><li>下载 <a

进行编译时出现乱码，如何解决？</p><p>A:</p><ul><li>该问题是由于项目整体使用 utf-8 编码，而编译用到的一些 windows 系统文件编码不是 utf-8（系统编码默认跟随地区，在中国为 GBK）</li><li>可以在控制面板中更改系统区域设置，具体操作方法为：打开控制面板 -> 时钟和区域 -> 区域，切换到管理选项卡，在 "非Unicode程序的语言" 下，选择更改系统区域设置，勾选 <code>Beta版：使用Unicode UTF-8提供全球语言支持</code> 后重启电脑。（细节可能随windows版本有差异，可在网上寻找详细教程）</li><li>注意，修改 windows 系统编码后可能会导致一些其他使用 GBK 编码的程序出现乱码，将系统区域改回后可复原，请自行斟酌。</li></ul><h2 id="_3-使用方式"
