c - ARM Keil 错误 #17 预期为 "]"、C3910W : Old syntax

Question

您好，我正在尝试在 Keil μVision v.5.12 上构建一个程序。

错误似乎只有“一个”(预计为 ])。但代码可以在我的 Linux 分区上运行(编译和运行时不会出现错误/警告)。

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？或者是 [0 ... 维度] 声明了我的矩阵？)

如interjay将其放在注释中，您正在使用特定于 gcc 的 C 扩展，并且在 Keil 上不兼容。

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 };
