Question

我编写了一个代码，该代码使用了CMSIS DSP库中的arm_cfft_f32函数。如何在我的项目的Makefile中添加CMSIS DSP库？

由STM32CubeMX为STM32F407芯片生成的Makefile。我将CMSIS统计信息中的.c和.h复制，转换和过滤函数文件夹复制到\ Src和\ Inc中的项目文件。

在STM32CubeMX生成的C_SOURCES下的Makefile中，我添加了：

Src/arm_cfft_f32.c \
Src/arm_bitreversal.c \
Src/arm_max_f32.c \
Src/arm_cmplx_mag_f32.c \

通过在Makefile中添加arm_max_f32.c和arm_cmplx_mag_f32.c，编译起来没有问题。但是，当我在项目中添加arm_cfft_f32时。我收到此编译错误，

我认为这可能对某人有所帮助。在将休止文件添加到项目Makefile之后，它可以很好地编译：

Src/arm_cfft_f32.c \
Src/arm_max_f32.c \
Src/arm_cmplx_mag_f32.c \
Src/arm_cfft_radix8_f32.c \
Src/arm_const_structs.c \
Src/arm_common_tables.c \

Makefile格式由STM32CubeMX自动生成。就我而言，我将CMSIS DSP .c和.h与STM32CubeMX生成的其他文件一起进行了测试。但是，它可以从系统中的CMSIS添加到修订目录中，并在C_SOURCES下的makefile中引用它们，并在C_INCLUDES下添加标头。

如何将转换功能从CMSIS DSP库添加到Makefile？
