这家伙很懒，什么也没写！

注释了这两句还是报错😭，注释了之后scons命令不能用了。

另外编译器路径有两个，一个是armcc，一个是armclang，路径如图：

armcc路径

armclang路径

但是两个都路径都试了还是报一样的错，而且在使用输入armclang路径时还是报armcc的错，很离谱。

armcc时的rtconfig.py文件

运行scons --target=mdk5报错

难道是menuconfig里面还要配置自动生成mdk工程的安装路径？

感谢感谢，之前只能曲线救国，scons编译后再scons --target=mdk5，虽然获取不到版本，但能生成正确的项目。

但是你说了keil.py的事之后，立即意识到我的keil安装路径名字可能和rtconfig.py里面定义的不一致，所以改了以下的东西

修改rtconfig.py中keil安装的目录

修改rtconfig.py读取keil文件的位置

但是在转为armclang方式编译时出现了问题
首先也是改rtconfig.py
改编译器名称和路径

检查读取路径，没有问题

修改keil.py读取的文件'armcc.exe'为'armclang.exe'

也就是armclang还是用不了，不过这样也满足了，至少能用armcc编译，慢是慢了点

其实脚本干的是就是解析控制台输出，然后找到版本信息从env控制台里再打印出来
