本文分享了一次使用STM32L0芯片及HAL库时遇到的编译错误经历，详细介绍了如何从包含头文件的细节出发解决问题的过程。

error: #20: identifier “HAL_StatusTypeDef” is undefined

我使用的是stm32l0的芯片，由于没有标准库可用，无奈只有折腾HAL库了。

首先，说下上面的错误怎么来的。我使用stm32cubeMX自动生成了代码，并且自己在工程里面新建了文件，文件里面需要用到HAL外设库中定义的宏定义，本来应该添加包含“stm32l0xx_hal_dac.h”,但是我发现”stm32l0xx_hal_conf.h” 中有所有外设的头文件，并且通过宏定义打开，所以我在该文件中添加了下面的语句：

#include "stm32l0xx_hal_conf.h"

编译后就出现了如下错误：
../Drivers/STM32L0xx_HAL_Driver/Inc/stm32l0xx_hal.h(374): error: #20: identifier
“HAL_StatusTypeDef” is undefined
HAL_StatusTypeDef HAL_Init(void);
../Drivers/STM32L0xx_HAL_Driver/Inc/stm32l0xx_hal.h(375): error: #20: identifier
“HAL_StatusTypeDef” is undefined
HAL_StatusTypeDef HAL_DeInit(void);
../Drivers/STM32L0xx_HAL_Driver/Inc/stm32l0xx_hal.h(378): error: #20: identifier
“HAL_StatusTypeDef” is undefined
HAL_StatusTypeDef HAL_InitTick (uint32_t TickPriority);
..\Drv\dac\drv_dac.c: 0 warnings, 3 errors

一直想不明白，“HAL_StatusTypeDef”变量在“stm32l0xx_hal_def.h”中已经有了定义，并且该变量也能成功跳转被找到。我已经包含了宏定义文件“stm32l0xx_hal_conf.h”，宏定义”HAL_DAC_MODULE_ENABLED“也使能了，添加的文件中变量也能成功跳转找到“stm32l0xx_hal_dac.h”中的定义，为什么会报错！

后来，我在整理main.c文件发现，其添加的头文件是“stm32l0xx_hal.h”，而不是文件“stm32l0xx_hal_conf.h”，于是，我将自己添加文件中改为

#include "stm32l0xx_hal.h"

再次编译工程，居然编译成功了。其中的原因，我还没有想明白，想明白了再回来补上。如果有大神知道原因，请指教！

STM32CubeMX生成HAL库文件，出现identifier “HAL_StatusTypeDef” is undefined错误

使用STM32CubeMX生成了一个工程文件，在使用串口库文件是，出现：“”identifier “HAL_StatusTypeDef” is undefined”错误。 经过测试发现是在添加的usart.c文件中，直接调用了#include "stm32f1xx_hal_uart.h"头文件，便会出现上述错误，解决方法经过测试，在调用#include "stm32f1xx_hal_uart.h"头文件时首先调用#include "stm32f1xx_hal.h"头文件，该头文件根据自己工程修改，我的

再给HAL库工程移植标准库的GPIO功能的时候出现了error: #20: identifier "HAL_StatusTypeDef" is undefined问题。而且报错的文件还是HAL库中的文件，现象如下： 这里我是打算添加一个GPIO口模拟I2C的驱动的。 问题解决： 首先注意一下初始化的函数。GPIO_InitTypeDef结构体与标准库中的成员的大小写，可赋的值不一样。开时钟也不一样。初始化函数调用HAL库自己的。尤其是引脚不同标准库是GPIO_Pin_6，而HAL库是GPIO_PIN_.

2.编译器报错的地方并不准确，比如报头文件 stm32g0xx_hal_rcc.h 中HAL_StatusTypeDef未定义，需要仔细查看报错是在编译那个.C文件的时候出现的。基本上都是自己编写的.c文件编译时出错才会报这种错误，需要注意需要统一 include “stm32g0xx_hal.h”， 而不是单独的include“stm32g0xx_hal_gpio.h>”stm32g0xx_hal_xxx.h之类头文件）

掌握了标准库，最近在搞stm32的HAL库，在自己编写任务时，出现了 error: #20: identifier “HAL_StatusTypeDef” is undefined的问题，通过查找定义是可以找到HAL_StatusTypeDef的位置，但是依旧报错。 解决办法：通过了解得知在HAL库中的stm32f1xx_hal_conf.h的头文件中对一些头文件做了使能，另一部分头文件是处于注释状态（即未使能）如下： 需要采用哪个头文件内的函数将其使能就行，可以去掉注释，也可换行重写，比如需要用到串口的

首先，我得回忆一下STM32 HAL库的结构和常见问题。 用户提供的错误信息来自多个HAL驱动文件，比如rcc、gpio、dma、adc等，这意味着问题可能不是单个文件的问题，而是整个项目配置的问题。常见的导致这种错误的原因...

这个bug比较常见，右键可以定位到相关头文件，但系统依旧报错，其实主要还是头文件的问题。 1.需要检查头文件中关于主程序所用到的部分是否已经使能，尤其是 “stm32f7xx_hal_con.h”和"stm32f7xx_hal.h"。 2.编译器报错的地方并不准确，比如报头文件 stm32f7xx_rcc.h 中HAL_StatusTypeDef未定义，需要仔细查看报错是在编译那个.C文件的时...

error: #20: identifier “HAL_StatusTypeDef” is undefined可以导航到，但是编译报错 Error: L6218E: Undefined symbol HAL_ADC_ConfigChannel (referred from h_adc.o). 等问题出现时，是一个原因 1. 问题原因 因为我们使用CubeMX生成工程，在生成工程时会自动配置stm32f7xx_hal_conf_template.h，屏蔽了一些HAL库，导致一部分HAL库被宏定义屏蔽了，我.

这也算是一个比较容易犯的一个错误，通过查找这个问题的原因让我醒悟了最重要的一点—在C站查找问题的时候一定要注意筛选答案，最好是筛选从最近一年的博客或则回答开始看（因为C站问题的重复率太高了），一些问题经过早期的提出起始维护者已经解决这个问题了，那么之前的回答就算是过时了，然而在我们不知情的情况下仍然按照博客提供的解决方案那就有可能是在浪费时间了。比如这个问题搜索时点击首先推荐我们的是点击量最多的地址：https://blog.youkuaiyun.com/wy212670/article/details/1057893

用stm32的hal库编辑代码时出现这个bug，右键可以定位到相关头文件，但系统依旧报错，其实主要还是头文件的问题。 1.需要检查头文件中关于主程序所用到的部分是否已经使能，尤其是 “stm32f1xx_hal_con.h”和"stm32f1xx_hal.h"。 2.编译器报错的地方并不准确，比如报头文件 stm32f1xx_rcc.h 中HAL_StatusTypeDef未定义，需要仔细查看报错是在编译那个.C文件的时候出现的。基本上都是自己编写的.c文件编译时出错才会报这种错误，需要注意需要统一 i
