Description

  • Treat every warning as an error - to catch problems early in CI.
  • add optional USER_CFLAGS/ USER_CXXFLAGS to override CFLAGS on per-project basis.

Potentially breaking - if forks contain code with warnings.

How to fix: fix your code - or add USER_CFLAGS=-Wno-error to the project file.

JIRA: CI-556

Summary of Changes

Hello @nalajcie, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a significant change to the build system by enabling the -Werror flag for C and C++ compilations. The primary goal is to enforce stricter code quality and catch potential issues early in the continuous integration pipeline, ensuring that all warnings are addressed as errors. This is a breaking change for any existing codebases that currently compile with warnings.

Highlights

  • Stricter Compilation Enforcement: The -Werror flag has been added to both CFLAGS and CXXFLAGS in Makefile.common, which will now treat all compiler warnings as errors, causing builds to fail if any warnings are present.
  • Impact on Code Quality: This change aims to improve overall code quality by preventing code with warnings from being merged, ensuring that developers address potential issues proactively and catch problems early in the CI pipeline.
