C++ 字段'；缓冲区'；具有不完整类型'；boost：：阵列<；char，4096ul>'；

我正试图从中编译一个简单的RESTAPI示例

但是当我运行makeall或justmake时，我会得到以下错误

我查看了头文件，似乎无法理解问题所在！谢谢你的帮助

此错误消息表示未包含定义为

boost:：array

的头文件

---

可能的修复方法：将

#include

添加到

crowu all.h

的顶部，它在我的pc上运行良好（boost 1.60、gcc 6.2.1、cmake 3.6.2）。mhm im使用boost 1.58，example_with_all.cpp是唯一不想合作的文件。其他文件编译并运行
