STM32CubeIDE - Auto-complete (Ctrl+Space) Not Proposing Any Functions

[MichalPorazko]

I m quite negatively surprised that suddenly (Ctrl+Space) stoped proposing any functions, as it is shown below:

or

I didn't change any settings, and suddenly it stopped working.

That is why I ve searched for any similar issues like mine on the forum and I ve found:

or
https://community.st.com/t5/stm32cubeide-mcus/why-does-the-index-not-work-and-how-to-make-it-work/td-p/269134

and none of these solutions worked for me..

I ve also tried to revuild the C/C++ indexer or just simply to create a new project but still no changes...

You can't call a function at the global scope. If you autocomplete within the main() function (or any other function), it will provide valid functions.

Thx, thats true as I ve checked , but why is it impossible to call a function at the global scope? I ve came across a tutorial where all the code was written in the global scope, so before the main function and everything seemed to work.

That's how C works. The entry point is in main(). You call functions there.

Technically you can call functions in assignments at the global scope, but that is not what is being done here.
