LabVIEW Restored Source and Compiled Code Cache: Synchronization After Backup Recovery
0 reputation · 11 Aug 2020, 19:20 UTC
When a LabVIEW project is restored from a file-system backup, the .vi, .lvlib, and .lvproj files are recovered as source text, but the compiled code cache and any previously generated executables are not necessarily part of that backup. A key uncertainty is how LabVIEW determines whether the restored source matches the cached compiled code. The 'Verify VI' utility can check for syntax errors, but it does not address cache consistency. Build specifications are restored as text, yet the executables they describe must be regenerated.
The question is what triggers a recompile after restoration—does LabVIEW compare file hashes, timestamps, or rely on manual action? And how can a user confirm that the restored project's build output corresponds exactly to the restored source, especially when the cache is missing or stale?
Specific questions:
- What criteria does LabVIEW use to decide that a restored VI needs recompilation?
- Is there a documented way to force a full rebuild of the project cache after backup restoration?
- How does the 'Find Missing Items' tool interact with the compiled cache for restored libraries?
