2015.4 Vivado HLS - ***。h：193：7：错误：在数字常量之前预期不合格的id
描述
当我将“ap_int.h”包含为头文件时，我在C仿真中遇到以下错误：

我该如何解决这个问题？
解
在上面的示例中，声明了一个与头文件冲突的宏。
例如，您有以下定义：
#define失败0
但是，头文件“basic_ios.h”包含以下定义：
布尔fail（）const{return（this-> rdstate（）＆（badbit | failbit））！= 0; }
预处理器不知道如何解释代码，它将“fail”替换为“0”。结果，出现此问题。
要解决此类问题，请注意您的宏定义不会与预定义的关键字冲突。
