IAR编译STM32F417时FPUTC重定义报错：参数类型FILE未定义。求大神指点
自己建的工程，仅用到CMSIS以及inc和src的文件，不知道为什么每次编译时都说fputc的参数类型"FILE"未定义如果用标准库中的EXAMPLE直接rebuild就没有，到底我哪错了，各位高手指点一下

RE:IAR编译STM32F417时FPUTC重定义报错：参数类型FILE未定义。求大神指点
需要在 IAR的Options -> General Options ->Library Configuration里设置一下函数库，将Library Configuration 中的Library 设置由"Normal"改为"Full"就可以了。回复:IAR编译STM32F417时FPUTC重定义报错：参数类型FILE未定义。求大神指点
试试这个

谢谢啊，改成full果然就好了:)回复第 2 楼 于2013-10-23 09:30:07发表:
