Start with the shadowsocksr-libev package and the failing src/udprelay.c compilation, especially server_recv_cb and the reported errors for server_ctx_t, dst_addr, and frag. Reproduce the failure with the package compile command, inspect the related structure definitions and upgrade changes, and consider the issue done when shadowsocksr-libev and luci-app-ssr-plus build successfully.
