Float format string flagged as error in editor

[Etienne_Parmentier]

I am using STM32CubeIDE version 1.18.1, and when using float formatting, STM32CubeIDE shows me an error with red squiggles about float formatting not being enabled in my toolchain.

When I go to Project Properties > C/C++ Build > Settings , I see no 'Tool settings' menu, and no linker option to specify. I am using CMake, so I believe this is normal since STM32CubeIDE does not know about my build configuration. How can I make this error disappear while using cmake ?

Is this just an error appearing in the IDE editor, or an actual error occurring during the build?

[Etienne_Parmentier]

This appears inside the editor, the build works just fine.

Hi, I figured that the %E format specifier does not triggers this errors inside the editor, the plot thickens !

It's the format specifier for scientific notation, I don't see why a C library that does not support %f would also %E.

I don't have all of these options availlable. here is what I see:

Did you import this project? Or did you start a new project, write code and run into this warning about the float?

I'm not sure why you're missing these sections?

Then your project is not-managed (makefile) and you have to add all needed options to your Makefile.

My project is using CMake, and builds correctly. The error seems to be coming from STM32CubeIDE error parsers, not my build configuration.
