ARM Keil 错误 #17 需要一个“]”，C3910W：旧语法

Question

您好，我正在尝试在 Keil μVision v.5.12 上构建程序。

错误似乎只有 "one"（预期 ]）。但是代码有效（在没有 err/warnings 的情况下编译和运行）on 我的 linux 分区。

我做错了什么？（我是否忘记了设置我的 keil 项目的任何内容？也许是 .h？或者 [0 ... 维度] 声明了我的矩阵？）

Answer 1

正如 interjay 在评论中所说，您正在使用特定于 gcc 且与 Keil 不兼容的 C 扩展。

来自 gcc documentation:

To initialize a range of elements to the same value, write ‘[first ... last] = value’. This is a GNU extension. For example,
int widths[] = { [0 ... 9] = 1, [10 ... 99] = 2, [100] = 3 };
