项目场景：

STM8L151G4XX单片机IAR工程编译报错.

问题描述

编译报错：Fatal Error[Pe035]: #error directive: “Please select first the target STM8L device used in your application (in stm8l15x.h file)”
这里的描述大概意思就是没有选择单片机型号分类，我们需要根据提示去设置。
打开 stm8l15x.h，我们可以看到以下代码：

#if !defined (STM8L15X_MD) && !defined (STM8L15X_MDP) && !defined (STM8L15X_HD) && !defined (STM8L15X_LD) \
&& !defined (STM8L05X_LD_VL) && !defined (STM8L05X_MD_VL) && !defined (STM8L05X_HD_VL) && !defined (STM8AL31_L_MD)#error "Please select first the target STM8L device used in your application (in stm8l15x.h file)"
#endif

这一部分就是为什么会报错的原因：没有进行相关宏定义
怎么去解决，在这个文件也有描述，需要根据单片机型号选择不同的宏定义

解决方案：

方法一：
直接在 stm8l15x.h文件修改，删掉需要的宏定义的注释符号，以STM8L151G4XX为例，根据上面描述，该型号属于 Medium density 。

/* Uncomment the line below according to the target STM8L15x device used in yourapplication*/
/* #define STM8L15X_LD */     /*!< STM8L15X_LD: STM8L15x Low density devices */#define STM8L15X_MD           /*!< STM8L15X_MD: STM8L15x Medium density devices */
/* #define STM8L15X_MDP */    /*!< STM8L15X_MDP: STM8L15x Medium density plus devices */
/* #define STM8L15X_HD */     /*!< STM8L15X_HD: STM8L15x/16x High density devices */

/* #define STM8L05X_HD_VL */  /*!< STM8L05X_HD_VL: STM8L052xx8 High density value line devices */
/* #define STM8AL31_L_MD */   /*!< STM8AL31_L_MD: STM8AL3x Medium density devices */

方法二：
设置路径Options->C/C++ Compiler->Preprocessor-Defined symbols
