Thanks @laroche for contributing to FreeRTOS+TCP. The change looks good to me.

I think it will be good to have the -Wredundant-decls option as part of our CI build checks CMakeLists.txt so that similar issues may not be added with future changes.

Do you wish to make those changes or prefer us to do so?

Hello Tony Josi,

sounds good, please also add this tion to CI build checks.

best regards,

Florian La Roche

@tony-josi-aws Thanks for adding the -Wredundant-decls compiler warning option, as part of the FRI project, we've updated the formatting job to run on ubuntu v22.04 -> https://github.com/FreeRTOS/iot-reference-arm-corstone3xx/blob/bda0d25a92fea54076c8d38e82298a51f17b6ac3/.github/workflows/ci.yml#L69, would it make sense to apply this here as well?
