Description: Summary Clang 21 added -Wunterminated-string-initialization. Under the build's -Werror, the macOS build fails compiling secp256k1: error: initializer-string for character array is too long [-Werror,-Wunterminated-string-initialization] static const unsigned char bip340_algo[13] = "BIP0340/nonce"; bip340_algo[13] is an intentionally non-null-terminated 13-byte tag in secp256k1. This extends the existing macOS Clang warning-suppression line in build_mpos.sh with -Wno-error=unterminated-string-initialization, matching the gnu-folding-constant / missing-field-initializers suppressions already on that line. Test plan scripts/build_mpos.sh macOS completes and produces lvgl_micropy_macOS on Clang 21 🤖 Generated with Claude Code
