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

The -fpermissive option is the default for historic C language modes (-std=c89, -std=gnu89, -std=c90, -std=gnu90).-Wall ¶. This enables all the warnings about constructions that some users consider questionable, and that are easy to avoid (or modify to prevent the warning), even in conjunction with macros.

c++ - How can I turn on (literally) ALL of GCC's warnings ... - Stack ...

GCC 4.3+ now has -Q --help=warnings, and you can even specify --help=warnings,C to just print out the C related warnings. I just wrote an m4 module to take advantage of this (it also supports Clang's -Weverything); see wget_manywarnings.m4. How to use it is pretty simple. Basically, the module turns every warn flag on.

C/C++/Objective-C compiler warning flags collection and parsers

This project includes tools and lists to figure out all warning flags that clang compiler and GNU Compiler Collection have for C family languages (C, C++, and Objective-C). This also shows all aliases and warning flags that a certain flag enables (prefixed with "#" character) so that you can easily see which flag is enabled by what. There are ...

How to compile with strict warning levels | LabEx

Common Warning Flags in GCC. For Ubuntu 22.04, GCC provides several warning flags:-Wall: Enable most common warnings-Wextra: Additional warnings beyond -Wall-Werror: Treat warnings as errors-pedantic: Enforce strict ISO C standards; Example Demonstration #include <stdio.h> int main() { // Potential warning: uninitialized variable int x; printf("%d", x); // This will trigger a warning return 0; }

GCC warning options for C programmers - Medium

In the context of warning options, it is relevant to mention GCC’s -std= flag for specifying a C standard. If unspecified, the default standard used will vary depending on the compiler's version.

0.11 — Configuring your compiler: Warning and error levels

In rare cases, it may be necessary to explicitly tell the compiler to not generate a particular warning for the line of code in question. C++ does not support an official way to do this, but many individual compilers (including Visual Studio and GCC) offer solutions (via non-portable #pragma directives) to temporarily disable warnings.

Compiler Warnings by compiler version | Microsoft Learn

For example, /Wv:17 reports warnings introduced in or before any version of Visual Studio 2012, and suppresses warnings introduced by any compiler from Visual Studio 2013 (version 18) or later. To suppress warnings introduced in Visual Studio 2015 update 2 and later, you can use /Wv:19.00.23506.

Why Bother with Compiler Warnings? - Cprogramming.com

Compiler warnings often surface issues that might be difficult to find during testing. For example, your compiler can warn you that you are reading the value of an uninitialized variable; this can be hard to find in testing because the value of the variable will be different every time the program runs - so sometimes it might still work! ...
