When building standalone Hexagon programs, using QuRT APIs without the full SDK stack can introduce linker issues and runtime assumptions that are not obvious at first glance.

1. Minimal runtime assumptions Start by confirming which QuRT symbols are pulled in by your current build. If the runtime expects services provided only by the larger SDK packaging, you may need lightweight stubs or a narrower feature set.

2. Linking strategy Keep the toolchain inputs explicit and compare the standalone link line with a known working sample. That usually reveals which system libraries or startup objects are missing from the standalone flow.

3. Validation steps After the binary links cleanly, test a minimal API path first before moving to threading, memory pools, or message passing. This makes it much easier to isolate where the integration actually breaks.
