keil中编译栏是灰色的+keil中添加C51库+keil中添加ARM库
2013-12-24 18:28阅读：
最近很多开始学ARM或51的朋友总问我说为什么编译栏是灰色的。 还有对于一些直接用别人程序的同学也会出现编译上的问题
--- Error: failed to execute 'E:\keil\C51\BIN\C51.EXE'
Target not created
第二个问题是
*** FATAL ERROR L210: I/O ERROR ON INPUT FILE:
EXCEPTION 0021H: PATH OR FILE NOT FOUND
FILE: E:\KEIL\C51\LIB\C51FPS.LIB
第二个问题的解决方法比较简单，直接下载C51FPS.LIB
http://zhidao.baidu.com/share/f056f2d272beea304f1f5ae0c573b0f7.html
C51FPS.LIB是51单片机生成hex文件时可能需要用到的文件库
今天就说下第一个问题的解决方法
我们Keil要能编译首先要有相对应的库文件，而很多商家提供给大家的MDK都是针对某一类型号芯片（这样软件会比较小）所以我们在用原来的keil建立工程编译其他文件的时候就会显示出错，因为没有对应的库文件
解决方法:
下载相对应的芯片库文件（在官方或者其他地方搜相应的C51或ARM库）
把下载的库添加到自己KEIL的安装文件下面
添加环境变量：用记事本打开tools.ini，添加如下（如果只更改C51就添加C51的就行，下面有ARM的也有ARMDS得）

这些环境变量要对应自己下载的芯片库，因为有的是没有的
还有PATH='E:\keil\C51'要改为自己电脑的路径，我的keil是安装在E盘的
然后重新打开keil，就可以新建工程编译运行了
