ESP HomeKit SDK示例工程首次编译失败的原因？怎么解决？

尝试跑通ESP HomeKit SDK提供的 Fan 示例工程，但在首次编译时出现错误，执行“idf.py set-target”或“idf.py menuconfig”等命令时报错，截取log中报错部分如下：

Code: Select all
CMake Error:
  Running

   'C:/Softwares/Espressif/tools/ninja/1.10.2/ninja.exe' '-C' 'D:/Workspace/eps_homekit/esp-homekit-sdk/examples/fan/build' '-t' 'recompact'

  failed with:

   ninja: error: build.ninja:21592: lexing error
    DEFINES = -D MFI_VER=""4.0-??? Linux ? Windows ?????????????
                                                                 ^ near here



CMake Generate step failed.  Build files cannot be regenerated correctly.
cmake failed with exit code 1


似乎是因为自动生成的 “build/build.ninja” 文件中出现了非法字符, “build/build.ninja” 文件的第21586-21592行内容为：
Code: Select all
#############################################
# Order-only phony target for __idf_esp_hap_core

build cmake_object_order_depends_target___idf_esp_hap_core: phony || cmake_object_order_depends_target___idf_esp_hap_apple_profiles

  DEFINES = -D MFI_VER=""4.0-??? Linux ? Windows ?????????????


其中触发错误的21592行内容为：

DEFINES = -D MFI_VER=""4.0-??? Linux ? Windows ?????????????

可见在“build/build.ninja” 的 21592 行出现了很多问号，可能是在自动生成时存在编码格式问题，“build/build.ninja” 文件中共有22处相同内容的行，请教如何修复这个问题 title="Confused">

IDF：v4.4；

操作系统：Windows。





[size=150%]详细步骤及完整log

1. 从https://github.com/espressif/esp-homekit-sdk 拉取 ESP-homekit-SDK 到本地；

2. 通过命令 ‘idf.py set-target esp32c3’ 设置芯片型号报错，完整log如下：
