How to I get Keil uVision 5 to compile CMSIS/DSP Library? (arm_math.h / int32_t is not a type name)

[Mnemocron]

I am trying to include the CMSIS/DSP Library into a uVision 5 Project generated by STM32CubeMX.

I went to "Runtime Settings" and included checked the DSP checkbox.

http://stm32f4-discovery.net/2014/10/stm32f4-fft-example/fft-enable-dsp-library-keil/

In main.c I added the include line <arm_math.h>

In the preprocessor settings I added the Symbol "ARM_MATH_CM4".

STM32F412Re / Keil uVision 5

What am I missing?

The compiler throws 30 errors like:

Pretty sure code from 2014 isn't CMSIS 5.6.x

Seem to be mixing things up, perhaps better to use contemporaneous sources.

Would those types be in stdint.h ?

I'd perhaps set up a coherent set of Include Paths so it doesn't pull from assorted locations the compiler pulls from a hat.

Adding the ../Drivers/CMSIS/DSP/Include path did the job. It now compiles without errors. Thank you!

Yeah...

Also worked for me just by adding separate Header file from STM firmware repository.

Was a great help.
