使用 ARM Compiler 6 编译和链接时标准 C 库链接器问题

Question

我在 ARM DS IDE 中遇到了一些链接器问题，我正在尝试为 ARMVv-8 架构、带有 ARM 编译器 6 的 Cortex A72 处理器构建代码。

我认为这些错误与 stdio.h 等标准库有关，math.h 这些错误不应该出现，因为链接器总是在 Linux 机器上寻找标准库路径。

我是不是遗漏了什么或者编译器、链接器出错了？

Answer 1

我认为您的情况无需指定 libpath。默认情况下，Arm 编译器附带用于 Arm 的 C 库。

Answer 2

必须有 GCC 才能使用 ARM 编译器 6 构建 Linux 应用程序：原因是 ARM 编译器 6 不包含 Linux 库，因此它需要使用 GCC 中的 glibc。
