DSP library not available in an H7 project

[smile]

“I have already #include "arm_math.h" and added the DSP library in CubeMX, so why am I still getting the following errors: undefined reference to 'arm_cfft_init_f32', undefined reference to 'arm_cfft_f32', undefined reference to 'arm_cmplx_mag_f32'?”

Unclear issue to me, please could you give us more details ?
Is it a build (compile / link steps) issue or code indexing (editor report) issue  ?

Another post here if helping : https://community.st.com/t5/stm32-mcus-products/arm-bitreversal-32-undefined-reference-in-cmsis-dsp/td-p/383155

I think it should be a problem with compiling links

Hi @smile ,

I couldn't spot the missing functions in your attachment so I'm not sure why you provided that.

Anyway, you just need to search your project for the missing symbols, if they're not present that's your problem. If they are present, then you need to check that paths to the sieve files are in your project's source paths. If the relevant sources are compiling but failing to link then you need to check the project link config.
