IAR 编译出错“declaration is incompatible with ”的解决方法
本帖最后由 kingsabbit 于 2014-11-12 23:11 编辑安装新版本后，IAR库和STM32库不兼容，会导致编译时出现“declaration is incompatible with ”等一堆错误，如下：
Building configuration: app - Debug
Updating build tree...
at24c16.c
Error: declaration is incompatible with "__nounwind __interwork __softfp unsigned long __get_PSP(void)" (declared at line 52 of "C:\Program FilesC:\Users\Administrator.EOEWQ4H5V1I17GH\Desktop\W5500_HTTPS\W5500_HTTPS\source\Libraries\CMSIS\CM3\CoreSupport\core_cm3.h 1086

Error: declaration is incompatible with "__nounwind __interwork __softfp unsigned long __get_MSP(void)" (declared at line 50 of "C:\Program FilesC:\Users\Administrator.EOEWQ4H5V1I17GH\Desktop\W5500_HTTPS\W5500_HTTPS\source\Libraries\CMSIS\CM3\CoreSupport\core_cm3.h 1106
(x86)\IAR Systems\Embedded Workbench 7.0\arm\inc\c\intrinsics.h")
此处省备N多错误
Error while running C/C++ Compiler
Total number of errors: 180
Total number of warnings: 0
此种问题的解决方法：
把core_cm3.h里面这句给注释掉，然后加上一句
#if defined (__ICCARM__)
//#include <intrinsics.h> /* IAR Intrinsics */
__intrinsic void __DSB(void);
#endif
完全没有任何警告和错误。 兄台如何发现要加这句话的？ eovlon 发表于 2017-12-26 23:46

遇到个这个问题，研究了很久才找到答案{:lol:}
