A diagnostic guide for Jule import failures and undefined symbols after refactoring, with a cause table, ordered checks, fixes tied to findings, and escalation criteria.
A diagnostic guide for GCC 7–13 Link-Time Optimization failures: recognize undefined reference and multiple definition errors, trace root causes through symbol visibility, ODR flag mismatches, and mixed LTO/non-LTO objects, then apply targeted fixes with version-aware commands.
Goal: Ensure that only the intended public symbols are present in the dSYM and archive when an Xcode target links Swift packages and relies on incremental builds. Uncertainty: The Mergeable build setting controls whether symbols from prior builds are retained; its behavior may differ across Xcode major versions, and changing the setting after a clean does no
Unintended public exposure of C symbols via @cImport in Zig Goal: Verify whether placing a @cImport block inside a pub block causes the imported C declarations to become part of the module’s public API, potentially allowing other Zig files to access them without an explicit pub qualifier. Constraints: Zig defaults to file‑private visibility; a @cImport inher
