+# lvgl-prebuilt-host-macos
+
+这个仓库负责为 Mac host 产出 LVGL 9.1 预编译包。
+
+它的职责是：
+
+- 固定 LVGL 官方版本。
+- 使用 Mac 工具链编译 `liblvgl.a`。
+- 导出成 `embedded-platform-core` 可以消费的包结构。
+
+它不负责：
+
+- 编译匠芯创 Luban-Lite 的 LVGL。
+- 编译全志 Linux 的 LVGL。
+- 封装 LVGL 控件 API。
+- 提供显示窗口、输入设备或平台 port。
+
+## 产物结构
+
+构建后生成：
+
+```text
+dist/lvgl/host_macos/
+  include/
+    lvgl.h
+    lv_conf.h
+    src/
+      ... 只包含 LVGL 头文件
+  lib/
+    liblvgl.a
+  LVGL_LICENCE.txt
+  lvgl_package.txt
+```
+
+`include/`、`lv_conf.h`、`lib/liblvgl.a` 必须成套使用，不能和其他平台的 LVGL 包混用。
+
+## 构建
+
+```bash
+./scripts/build_host_macos.sh
+```
+
+## 验证
+
+```bash
+./scripts/verify_package.sh
+```
+
+## 版本
+
+- LVGL tag: `v9.1.0`
+- LVGL commit: `e1c0b21b2723d391b885de4b2ee5cc997eccca91`
+- 平台: `host_macos`
