Compiler Warnings with "-Wpedantic"

Masmiseim — Fri, 06 Sep 2024 15:08:19 GMT

Hello NXP team,

could you test the target code for Freemaster (the one running on the microcontroller) with higher warning levels and make it warning-free? May I recommend the following warning flags:

-Wall
-Wextra
-Wpedantic

The code raises several Compiler-Warnings with the warning-settings from above. The following three warnings, lead to linker errors when LTO is activated:

The following linker Errors with LTO active are created when the warnings are not solved:

Yes, at first glance these seem to have nothing to do with the warnings. It took me a while to understand the problem.

GCC13 was used on iMXRT1170.

Thanks and best regards

I agree

To add to this, I also suggest to remove warnings generated with -Wundef (which seems not to be included in -Wall?)as the Freemaster header files checks a lot of potentially undefined precompiler constants.

Hello Michael,

we did address most of the -Wpedantic issues in the latest version of the FreeMASTER driver. You can check the code here: https://github.com/nxp-mcuxpresso/mcux-freemaster

We'll continue the effort in next versions.

Regards,
Michal

Michal, thanks for your prompt response. I think we do not use the latest driver code from this repository right now. We will check this out.
Have a good day
