STM32F4xx CMSIS with clang compiler / many warnings

Hello,

I'm starting a project which uses an STM32F4xx as MCU. I want to use the STM32CubeMx tool for hardware setup and the ST CMSIS libraries for hardware control.

As compiler I want to use the Keil ARM v6.5 compiler (which is clang). Problem is, if I compile the CMSIS sources with the __GNUC__ definition, the build is successful but it generates really a lot of warnings (about 1000 for a few CMSIS files).

Now I'm wondering if there is a better way (or another library from ST?) to use the ST CMSIS files with clang or not?

Are there any experiences using the CMSIS with clang / arm compiler V6? (is this combination recommended?).

Thank you in advance!

Hello,

What exactly did the warnings message say?

Maybe you should ensure that you are included the proper CMSIS library into your project and the paths are set up correctly.
