ESP-IDF：编译 ULP 模块：工具与列表 ['2.35_20220830'] 中支持的版本不匹配：/usr/bin/cc

Question

我有一个带有 ULP 模块的 esp-idf 程序，如下所示：

idf_component_register(SRCS "ulp-experiment.c" INCLUDE_DIRS "." REQUIRES ulp)

# a name for the app that runs on the low power chip
set(ulp_app_name lp_core_main)

# sources for the program that runs on the low power chip
set(ulp_sources "ulp/ulp.c")

# sources that run on the main CPU and need to directly include generated interfaces to low power device
set(ulp_exp_dep_srcs "ulp-experiment.c")

# embed the low power program into the main program
ulp_embed_binary(${ulp_app_name} "${ulp_sources}" "${ulp_exp_dep_srcs}")

我正在为esp32c6芯片编译。

当我使用 idf.py build 构建时，我得到：

CMake 错误位于 /home/alex/code/esp-idf/tools/cmake/tool_version_check.cmake:36（消息）：

  Tool doesn't match supported version from list ['2.35_20220830']:
  /usr/bin/cc

  Please try to run 'idf.py fullclean' to solve it.

Call Stack (most recent call first):
  CMakeLists.txt:15 (check_expected_tool_version)

我尝试按照建议运行 idf.py fullclean，但没有帮助。我应该怎么做才能解决这个问题？

检查 /usr/bin/cc 的版本会给出以下结果：

$ /usr/bin/cc --version

我不确定为什么框架要访问我的常规 C 编译器。我以为它有自己的适用于 esp32c6 架构的 C 编译器。

构建日志的相关部分如下所示：

Answer 1

解决方案是运行

idf.py menuconfig

并启用 ULP 模块。
