There "seems to be " something missing in this message.

Nope, the message is very much correct. The fist line says it all: You're running code in the debugger that's not built with debug information.
"Section" is a code section:
https://docs.oracle.com/cd/E19683-01/817-3677/chapter6-46512/index.html#:~:text=Sections contain all information in,one section header describing it.Sections contain all information in an object file except the ELF header, the program header table, and the section header table. Moreover, the sections in object files satisfy several conditions:
-
Every section in an object file has exactly one section header describing it. Section headers can exist that do not have a section.
-
Each section occupies one contiguous, possibly empty, sequence of bytes within a file.
-
Sections in a file cannot overlap. No byte in a file resides in more than one section.
-
An object file can have inactive space. The various headers and the sections might not cover every byte in an object file. The contents of the inactive data are unspecified.

@kshegunov I have numerous alligators to chase...
In short - building an New Project from scratch runs "debug" without doing anything special. Stand by. -
