How to disable warnings when compiling C code? - Stack Overflow

That's only partly correct. Some gcc warnings flag things that are best-practices as warnings and encourage you to write broken, non-portable code in their place. The best example I can think of is a braces warning for mbstate_t state = { 0 }; which encourages people to use memset(&state, 0, sizeof state); instead.

Warning Options (Using the GNU Compiler Collection (GCC))

Warn whenever a local or static variable is unused aside from its declaration. This option implies -Wunused-const-variable=1 for C, but not for C++. This warning is enabled by -Wall. To suppress this warning use the unused attribute (see Specifying Attributes of Variables). -Wunused-const-variable ¶-Wunused-const-variable=n

How to manage compiler warning levels in C | LabEx

Compiler Warning Basics What are Compiler Warnings? Compiler warnings are diagnostic messages generated by the compiler during the compilation process. Unlike errors, warnings do not prevent code from compiling, but they indicate potential issues or non-optimal programming practices that might lead to unexpected behavior or future problems.

Why should I always enable compiler warnings? - Stack Overflow

Compiler warnings are your friend. I work on legacy Fortran 77 systems. The compiler tells me valuable things: argument data type mismatches on a subroutine call, and using a local variable before a value has been set into the variable, if I have a variable or subroutine argument that is not used.
