tuya/TuyaOpen

AI Summary: The issue is a compilation error on macOS when building the lwip library within the TuyaOpen framework's `your_chat_bot` example. The error stems from missing definitions for `in_addr_t` and `struct timeval`. The task involves diagnosing the root cause of the missing definitions (likely a missing header file or incorrect include paths), and correcting the build process to successfully compile the lwip library for the T5AI platform on macOS.
