A Chinese developer recently published a detailed account of debugging a Unity project on Huawei P30 running HarmonyOS 4.0, where native library loading failed due to RELRO relocation exceptions. The post systematically walks through the investigation, identifying the root cause as incompatible linker behavior and symbol export issues. The solution involved optimizing linker flags, strategically using static libraries, and standardizing symbol exports. This case is significant for the global developer community as HarmonyOS expands beyond China, and Unity developers increasingly need to support this platform. The debugging methodology—isolating the issue, testing linker configurations, and leveraging static linking—provides a reusable pattern for similar compatibility problems. While the post is platform-specific, the approach to diagnosing native library loading failures is broadly applicable to other mobile and embedded systems.
