How Can I Enable the Most Thorough C Warnings in g ?

Enabling Thorough C Warning in g

In C , it's essential to set up warning flags to identify and address potential issues during code compilation. This ensures the code's reliability and correctness.

A Comprehensive Set of Warning Flags

The following set of warning flags is designed to catch the maximum level of warnings while excluding those deemed unnecessary or with a high false-positive rate:

-pedantic -Wall -Wextra -Wcast-align -Wcast-qual -Wctor-dtor-privacy -Wdisabled-optimization -Wformat=2 -Winit-self -Wlogical-op -Wmissing-declarations -Wmissing-include-dirs -Wnoexcept -Wold-style-cast -Woverloaded-virtual -Wredundant-decls -Wshadow -Wsign-conversion -Wsign-promo -Wstrict-null-sentinel -Wstrict-overflow=5 -Wswitch-default -Wundef -Werror -Wno-unused

Notes on Excluded Warnings

Some warnings that are not included in this set are:

• -Waggregate-return: May not be considered an error.
• -Wconversion: Can trigger false positives in certain scenarios.
• -Weffc : Requests initialization of all data members, which may not always be desirable.
• -Winline: Concerns the use of inline functions, which is not commonly used for optimization purposes.
• -Wnormalized=nfc: Is already set as the default option.
• -Wpadded: Used occasionally to optimize class layouts but not left on permanently.
• -Wstrict-aliasing: Level 1 and 2 may provide more warnings with fewer false positives.
• -Wswitch-enum: Requires explicit handling of every switch statement.
• -Wunsafe-loop-optimizations: Generates many spurious warnings.

For a more detailed explanation of each excluded warning, please refer to the original thread where the set of flags was compiled: [Flags to enable thorough and verbose g warnings](https://stackoverflow.com/questions/1409995/flags-to-enable-thorough-and-verbose-g-warnings).
