Worked on enhancing cross-platform compatibility for the bytecodealliance/wasm-micro-runtime project by addressing a key issue in the C API’s shared library integration. Focused on API design and C programming, the developer adjusted the WASM_API_EXTERN macro to ensure default symbol visibility when compiling with GCC or Clang. This technical change allowed the wasm_c_api to function correctly in shared libraries on Linux and macOS, reducing platform-specific integration issues. The update improved downstream packaging workflows and demonstrated careful attention to cross-compiler portability. The work contributed to faster deployment and easier integration for users relying on cross-platform shared library support.
