答案对人有帮助，有参考价值 0 这个错误是由于 Keil AC6 编译器不支持 `__forceinline` 这个关键字导致的。`__forceinline` 是 ARM Compiler 5 (AC5) 的关键字，但在 ARM Compiler 6 (AC6) 中，这个关键字被替换为 `__attribute__((always_inline))`。要解决这个问题，你可以按照以下步骤修改代码：找到 `portmacro.h` 文件：这个文件通常位于 `Middlewares/Third_Party/FreeRTOS/Source/portable/RVDS/ARM_CM3/` 目录下。修改 `portFORCE_INLINE` 宏定义：在 `portmacro.h` 文件中找到 `portFORCE_INLINE` 宏定义，并将其修改为适用于 AC6 的语法。修改前： `#define portFORCE_INLINE __forceinline` 修改后： `#define portFORCE_INLINE __attribute__((always_inline))` 保存文件并重新编译：保存修改后的文件，然后在 Keil 中重新编译项目。其他可能的解决方案使用 AC5 编译器：如果你不需要使用 AC6 的特性，可以考虑切换回 AC5 编译器。在 Keil 中，你可以通过项目设置将编译器从 AC6 切换回 AC5。更新 FreeRTOS 版本：如果你使用的是较旧版本的 FreeRTOS，考虑更新到最新版本。新版本的 FreeRTOS 可能已经修复了与 AC6 的兼容性问题。检查其他文件：如果问题不仅仅出现在 `portmacro.h` 文件中，你可能需要检查其他文件，确保所有 `__forceinline` 都被替换为 `__attribute__((always_inline))`。通过以上步骤，你应该能够解决 Keil AC6 下编译 FreeRTOS 代码时遇到的 `__forceinline` 错误。
