Proposal: build clean with recent compilers for system-agnostic S-CORE

^{Originally posted by **AlexanderLanin** September 2, 2025}
## Context
The current setup primarily relies on **qcc for QNX 8.0 = gcc 12**.
However, SCORE is expected to be integrated into **multiple target environments**.
Relying on a single compiler/version locks SCORE to one ecosystem and makes broader adoption difficult.

## Problems
- **Limited scope:** qcc/gcc 12 is tied to QNX 8.0. For future targets beyond QNX, this setup does not scale.
- **Missed diagnostics:** Newer and other compilers provide stronger checks “for free,” reducing the need for additional static-analysis tools.

## Proposal
Adopt a **“build clean with recent compilers”** philosophy to make SCORE as **system-agnostic as safety allows**:
- Define a **minimum set of supported compilers** (covering gcc and clang, old and modern).
- Require all SCORE modules to build cleanly with this set.
- Ensure compiler support covers both **safety-relevant targets** and **integration into arbitrary environments**.

## Benefits
- **System-agnostic:** SCORE can integrate into a wide range of environments, not just QNX.
- **Future-proof:** Easier adaptation to new platforms.
- **Higher quality:** Modern compilers catch issues that older ones miss.
- **Clear baseline:** Every module is validated against the same modern standards.

## Next Steps
- A **go-ahead from tech leads** to move forward.
- Infrastructure community defines the **exact compiler set and versions**.
- Update CI pipelines to enforce clean builds across the selected compilers.

❓ **Requested decision:** Should SCORE adopt a modern **system-agnostic compiler baseline** (build clean with recent compilers, not just qcc/gcc 12) to support integration into arbitrary environments as far as safety allows?
