The problem is as follows , compile STM32H7 Of DSP Error in library source code , The reason is also simple , Pay attention to the use of Cortex-Mx Of DSP library , Add the path directly when the header file is included Libraries\CMSIS\Include The header file inside is ok , It doesn't need to be added Libraries\CMSIS\DSP\Include, This is because of the path Libraries\CMSIS\Include It already contains DSP The header file of the library . This error is because it contains more Libraries\CMSIS\DSP\Include
route , Why , It may be because there is a problem with compiling through macro selection , Some don't need to be compiled , The result is something wrong .

The compilation is successful as shown in the figure below ：
