无法使用安装了brew的arm-none-eabi-gcc编译器构建嵌入式arm应用程序

Question

这是我正在尝试构建的应用程序：

#include <string.h>
#include <stdio.h>

int main() {
  printf("hello world\n");
  return 0;
}

这是我安装了brew的编译器的输出：

> arm-none-eabi-gcc test.c
test.c:1:10: fatal error: string.h: No such file or directory
    1 | #include <string.h>
      |          ^~~~~~~~~~
compilation terminated.

这是我从 ARM 下载的编译器的输出。 （这些错误是预料之中的（我试图弄清楚为什么新的arm工具链会发生这种情况） - 当我编译一个完整的嵌入式项目时，这个编译器可以工作（尽管有类似的警告），而自制软件安装的编译器却不能）

为什么自制安装的编译器找不到标准头？我怀疑生成的警告和未找到的标头在某种程度上相关，并且我不明白此工具链中的标准库实现发生了什么情况。

Answer 1

arm-none-eabi-gcc(mac) 中没有“stdint.h”

我发现这可以解决我的问题。

总长：

从brew卸载

arm-none-eabi-gcc

并安装工具链：

brew install --cask gcc-arm-embedded
