信息：
芯片: ESP32-PICO-D4
ESP-AT version: release/v2.1.0.0_esp32的基础上新增了自定义指令(原本使用IDF release v4.0,但该版本不再维护，故切换到v4.3)
ESP-IDF version: release v4.3 commit:588436db47da792736dade1c21fcbf2c879456a4
(官方固件ESP32-PICO-D4_AT_Bin_V2.4.0.0.zip 基于这个版本的IDF）
工具链环境等：通过install.sh 安装 工具链 python环境 依赖包等，通过export.sh设置环境变量

编译时出现如下问题：

编译hello_world的例程也有同样的问题

Hi,
每个 ESPAT 版本都有对应的 IDF 版本，如果要更新 IDF 版本可以参考文档：《如何更新 ESP-IDF 版本》（https://docs.espressif.com/projects/esp ... ml#esp-idf） 如果您不想自己在 AT v2.1 版本适配 IDF 4.3 的话，其实可以直接使用 AT v2.4，因为它是兼容以前的功能。

好的，谢谢回复，我这边切换版本也是按文档所述操作的。
接下来我就尝试基于ESP-AT v2.4 增加自定义的改动。
仍然让我奇怪的是，基于ESP-IDF v4.3（commit:588436db47da792736dade1c21fcbf2c879456a4）编译自带的examples， locks.c也报错，但ESP-AT v2.4工程编译正常。
