本文解决了一个Keil编译器中常见的问题，即使编译成功，但在头文件前出现红色“X”。通过修改UVCC.ini文件，将特定头文件添加到其中，成功消除了错误标记，使界面更加整洁。

今天用Keil的时候出现了一个能逼死强迫症的问题。

具体表现是编译通过了，输出显示 0 warning 0 error ！。

但是在include头文件时，某一行前面出现了一个红色的“X"！

这个其实也没有什么影响，可以直接忽略掉，因为编译通过了，下载运行也没有任何问题，但是还是不能忍，不能忍呀~

于是我就找了找解决办法，果然被我找到了（ > _ < ）

Keil报错.....(问题解决从未开始到放弃) 这篇博主说了，因为Keil版本的问题可能升级下版本就可以解决这个问题，不过我用的版本目前是V5.25，和博主文章里提到的版本不同，或者直接忽略掉。

不过我没有像博主说的直接忽略掉，而是找到了Keil的安装目录下的 UV4 文件夹，搜索找到文件夹中的 UVCC.ini 文件，用记事本打开，将报错的那个头文件添加到文件中 （即添加一句 xxxx.h  = *）。

然后保存，关掉之前打开的Keil，重新再打开Keil就会发现红色的“X"不见了，不见了。顿时舒心很多。谢谢上文博主提供的方法。

程序正常编译可以通过，也不报错，但是头文件“sys.h”有一个下划红线（因为我的已经改过了，所以此处用红色标记了下，鼠标光标靠近，提示我有错误：KEIL报错：fatal error in include chain(stm32f4xx_conf.h): stm32f4xx_dma.h not found ，也是找到了网上也有人遇到了相同的问题，https://blog.csdn.net/gin_love/article/details/87633814附上链接 解决办法： 找到keil软件安装路径的U..

在移植工程的时候，头文件包含了cortex系列的头文件和cmsis的armcc头文件。 编译过后是0错误0警告的，程序下载运行也是没问题的。但是keil左边有个大叉号，提示头文件错误error in include chain(cmsis_armcc.h):expected identifier or '(' 。 经过逐层寻找发现在cmsis_armcc.h中的静态内联没有定义，但是gotodefine依旧可以跳转，于是把cm0plus.h头文件include一下，好了叉号没有了。。。但是！！编译工程全

我们也可以通过替换global.prop文件的方式，一键设置已经修改好的代码风格。最近在学习某原子stm32的HAL库视频，被教学代码的风格深深吸引，感觉keil默认代码风格是越看越别扭，所以决定自己修改一下代码的格式，总结了两种方法，这里分享给大家，同时分享一个修改完代码格式后又遇到的一个报错的解决方法。方法也很简单，要么去文件里include一下头文件，或者直接用记事本打开上面那个UV4文件夹里的UVCC.ini，在最后添上xxxxxxx.h = *比如我的就是 cmsis_armcc.h = *

<think>我们面对的问题是STM32F1xx项目中编译时出现头文件重复声明错误，特别是关于stm32f10x.h头文件中一些宏和中断号的重复声明。根据引用内容，我们可以分析错误原因并给出解决方案。错误原因分析：1.引用[2]提到stm32f10x.h定义了器件、中断线、数据类型、寄存器等，这意味着该头文件是项目必须的。2.引用[3]提到core_cm3.h中定义了CM3内核的寄存器组和中断相关寄存器（如NVIC），而stm32f10x.h也会定义类似内容，可能导致重复定义。3.错误信息中提到的宏（如__MPU_PRESENT,__CM3_REV,__NVIC_PRIO_BITS）和中断号（IRQn）很可能在多个头文件中被重复定义。解决方案：1.检查头文件包含顺序和条件编译：确保在包含stm32f10x.h之前没有包含core_cm3.h（或类似内核头文件），因为stm32f10x.h内部可能已经包含了core_cm3.h。同时，使用头文件保护宏（#ifndef...#define...#endif）防止重复包含。2.在STM32标准库中，stm32f10x.h已经包含了core_cm3.h，因此我们不应在其他地方再次包含core_cm3.h。检查项目中是否有显式包含core_cm3.h的地方，如果有，请移除。3.对于标准库中的头文件，我们应使用库提供的配置方式。例如，在包含stm32f10x.h之前，应该先包含stm32f10x_conf.h（该文件用于配置使用哪些外设头文件），并且确保在stm32f10x_conf.h中没有包含任何会导致重复定义的头文件。4.如果项目中使用了其他库（如FreeRTOS），则需要注意FreeRTOS的头文件可能也会包含core_cm3.h。例如，引用[4]中提到的portmacro.h可能包含与内核相关的定义。此时，我们需要调整包含顺序或通过宏定义来避免重复。具体步骤：步骤1：检查main.c（或其他顶层源文件）中的头文件包含顺序，确保如下：#include"stm32f10x.h"//这个头文件应该在最前面，因为它包含了内核定义和芯片外设定义//然后包含其他头文件，如FreeRTOS的头文件步骤2：检查是否在stm32f10x.h之前包含了其他内核相关的头文件（如core_cm3.h），如果有，请删除。步骤3：检查stm32f10x_conf.h文件，确保它只包含了外设的头文件（如stm32f10x_gpio.h,stm32f10x_rcc.h等），而不要包含core_cm3.h或类似的内核头文件。步骤4：如果使用FreeRTOS，注意FreeRTOSConfig.h中可能包含一些与内核相关的定义。确保在FreeRTOSConfig.h中，我们使用条件编译来检查是否已经定义了这些宏，例如：#ifndef__NVIC_PRIO_BITS#define__NVIC_PRIO_BITS4//根据实际情况设置优先级位数#endif步骤5：如果错误依然存在，可以尝试在编译器设置中定义宏，例如在预处理器选项中添加：__MPU_PRESENT=0//根据你的芯片是否具有MPU来设置，STM32F1通常没有MPU，所以设为0__CM3_REV=0x0201//根据芯片手册设置__NVIC_PRIO_BITS=4//设置优先级位数这样，在头文件中这些宏已经被定义，就不会再重复定义。步骤6：检查项目中是否有多个地方包含了stm32f10x.h，可以通过头文件保护来避免重复包含，标准库头文件通常已经有保护，但还是要检查。步骤7：如果上述步骤无法解决，可以查看错误信息中重复定义的具体变量名，然后使用预编译宏进行条件定义。例如，在包含stm32f10x.h之前，先定义这些宏，这样在stm32f10x.h内部就会跳过定义。示例代码（在包含stm32f10x.h之前）：#define__MPU_PRESENT0#include"stm32f10x.h"但这种方法需要谨慎，因为必须确保定义的值正确。步骤8：如果错误发生在第三方库中，考虑更新第三方库或修改第三方库的头文件（在确保合法的情况下）添加头文件保护。常见错误原因：-重复包含头文件：同一个头文件被直接或间接包含了两次。-头文件保护缺失：虽然标准库头文件通常有保护，但自定义头文件可能没有。-不同库之间的冲突：例如标准外设库和FreeRTOS的portmacro.h都定义了相同的内容。通过以上步骤，通常可以解决重复声明的问题。</think>### 解决STM32F1xx头文件重复声明错误 在STM32F1xx项目中，`stm32f10x.h`与其他头文件（如CMSIS内核头文件）发生宏和中断号的重复声明，本质上是**头文件包含顺序冲突**或**多重包含防护失效**导致的。以下是系统解决方案： --- ### 错误原因分析 1. **CMSIS与标准库冲突** CMSIS内核头文件（如`core_cm3.h`）和`stm32f10x.h`均定义了以下内容： - 内核宏：`__MPU_PRESENT`, `__CM3_REV`, `__NVIC_PRIO_BITS` - 中断号：`IRQn_Type`枚举（如`NonMaskableInt_IRQn`） - 引用[3]中提到的NVIC寄存器组定义 2. **包含顺序错误** 若在项目中先包含`core_cm3.h`再包含`stm32f10x.h`，后者尝试重复定义相同内容。 3. **条件编译失效** 标准库未正确检测到CMSIS头文件已被包含（防护宏未生效）。 --- ### 解决方案（分步操作） #### 步骤1：统一头文件包含顺序 **强制先包含芯片级头文件**，确保`stm32f10x.h`优先处理： ```c // main.c 或 stm32f10x_conf.h #include "stm32f10x.h" // 必须在所有头文件之前 #include "core_cm3.h" // 内核文件在后 ``` #### 步骤2：检查标准库配置 在`stm32f10x.h`中，确认以下防护宏已启用（约第80行）： ```c #if !defined (__STM32F10x_H) // 防护宏必须存在 #define __STM32F10x_H // ...原有内容... #endif /* __STM32F10x_H */ ``` #### 步骤3：预处理宏定义覆盖 在编译器全局预定义中**强制覆盖冲突宏**（以Keil MDK为例）： 1. 打开工程选项 → C/C++选项卡 2. 在`Define:`字段添加： ``` __MPU_PRESENT=0, __CM3_REV=0x0201, __NVIC_PRIO_BITS=4 ``` （值根据具体芯片型号调整，STM32F103通常为`__CM3_REV=0x0201`） #### 步骤4：中断号冲突处理 若仍出现`IRQn_Type`重复定义： 1. 在`stm32f10x.h`中注释掉重复定义（约第423行）： ```c // typedef enum IRQn { ... } IRQn_Type; // 注释此行 ``` 2. 确保`core_cm3.h`中的定义生效（CMSIS标准定义优先）。 --- ### 关键原理说明 1. **防护宏作用** `stm32f10x.h`通过`__STM32F10x_H`宏避免重复包含，但若`core_cm3.h`在其之前被包含，内核相关定义会被二次声明[^3]。 2. **宏优先级** 编译器预定义的宏（步骤3）会覆盖头文件内部定义，从根本上避免冲突[^1]。 3. **CMSIS兼容性** STM32标准库基于CMSIS实现，必须保持内核头文件的权威性，外设库应服从其定义[^2]。 --- ### 预防措施 - **头文件标准化**：始终以`stm32f10x.h`作为首个包含的头文件。 - **版本检查**：确认标准库版本（引用[1]中`__STM32F10X_STDPERIPH_VERSION`）与CMSIS包匹配。 - **清理冗余包含**：移除手动包含的`core_cm3.h`或`stm32f10x_conf.h`外其他外设头文件。 > 通过以上步骤，可彻底解决`__MPU_PRESENT`、`__CM3_REV`等宏及中断号的重复声明问题。若涉及RTOS（如FreeRTOS），需额外检查其`portmacro.h`是否包含内核文件（引用[4]），必要时调整包含顺序。
