Eclipse挂载aws代码出现错误的原因？如何解决？

硬件部分:esp32-s3 –wroom-1

软件部分: esp-idf-v4.4.2

开发环境:Wondows 7

IDE:  Eclipse IDE for C/C++ Developers Version: 2022-06 (4.24.0)

问题描述:

原本在keil c mdk 用AT command开发蛮顺手的，但后来转到IDF确让我挫折满满，编译后出现一堆问题，在网上没有找当我想找的答案，虚心求教一下

出现问题描述:

undefined reference to `app_main'

undefined reference to `app_main'

Symbol 'NULL' could not be resolved

Symbol 'ESP_ERR_NVS_NO_FREE_PAGES' could not be resolved

Symbol 'ESP_ERR_NVS_NEW_VERSION_FOUND' could not be resolved

esp-idf/freertos/libfreertos.a(port_common.c.obj): in function `main_task':



设定步骤

1.        开启idf 专案

2.        挂载 https://github.com/espressif/esp-aws-iot 项目内容(esp-aws-iot-masterexampleshttp)透过import -> file system 方式把*.c

        *.h挂载进来

3.        Cmakelist.txt不知道该如何修改

                                
                        
                                             
               
CMakeList.txt

1.

set(COMPONENT_SRCS

    "app_main.c"

    "http_demo_mutual_auth.c"

    "http_demo_utils.c"

    )



set(COMPONENT_ADD_INCLUDEDIRS

    "."

    "${CMAKE_CURRENT_LIST_DIR}"

    )



idf_component_register(SRCS "${COMPONENT_SRCS}"

                       INCLUDE_DIRS ${COMPONENT_ADD_INCLUDEDIRS}

                      )

2.

# The following five lines of boilerplate have to be in your project's

# CMakeLists in this exact order for cmake to work correctly

cmake_minimum_required(VERSION 3.5)



set(EXTRA_COMPONENT_DIRS "$ENV{IDF_PATH}/examples/common_components/protocol_examples_common"

                                                 "${CMAKE_CURRENT_LIST_DIR}/../../../libraries/coreHTTP"

                                                 "${CMAKE_CURRENT_LIST_DIR}/../../../libraries/common/posix_compat"
