OSS_REAL_CODE_NOT_LINKED
OSS_REAL_CODE_NOT_LINKED (0x80093020) is an OSS ASN.1 runtime result for generated REAL handling code missing. The build contains a path to an ASN.1 REAL value but not the generated or linked code needed to process it. Because link map entries for REAL support is central to this condition, Microsoft’s HRESULT range and the OSS Nokalva return-code documentation should be read together. Start the investigation by recording compiler options and generated source list, then separate the encoded value from generated artifacts, call arguments, and the runtime package actually loaded by the process.
Where processing stopped
At the generated REAL handling code missing boundary, capture the first OSS function returning the value and note whether the operation was encode, decode, copy, compare, constraint validation, or trace setup. Preserve the selected PDU, encoding rules, and first PDU that references REAL; otherwise an outer certificate or security wrapper may hide the useful codec result behind a generic failure.
Isolation sequence
- force a link-time reference in a test target
- clean and regenerate all codec sources
- Compare static and DLL build configurations
Facts that change the conclusion
- link map entries for REAL support
- compiler options and generated source list
- first PDU that references REAL
Similar names, different faults: the result
Installing a DLL alone may not help when the missing piece is code omitted from the linked generated module.
Instrumentation
Where link map entries for REAL support can expose sensitive content, a hash plus a bounded structural excerpt is safer than the complete payload. Use compiler options and generated source list together with OSS module paths and versions logged once per process so packaging differences can be correlated without flooding normal diagnostics.
Completion check: the result
Include the REAL implementation in the target and add a small encode/decode link test to CI.
