构建ESP32项目报错“undefined reference” 开发环境:ESP32-platformio-arduino 语言:C/C++ 在main.cpp(主程序)里面使用了自己编写的头文件的内容,语法上没有错误,头文件和.cpp文件都放在了正确的目录下面(头文件在include文件夹下,.cpp在src文件夹下),构建项目的时候总是出现类似于 undefined reference to `Display...
针对你遇到的“esp32 undefined reference to `app_main'”问题,我为你整理了以下可能的解决方案: 确认app_main函数已在代码中定义: 在ESP32的IDF(IoT Development Framework)中,app_main是程序的主入口点,类似于传统C/C++程序中的main函数。你需要确保你的代码中有一个名为app_main的函数定义。这个函数通常位于...
