TIVA C tm4c123GH6PM 用tm4cdemo里面的lab4_timer，按照work_shop_workbook里面的步骤，编译时出现如下，不明白。

This project does not contain a buildable RTSC Configuration (.cfg) file. In order for it to build, this project must contain one RTSC Configuration file that is not excluded from build.

Michael Sun：

楼主用的啥IDE？把工程传上来看一下吧。

回复 Michael Sun:

不知道为什么我把旧工程删掉，重新建立，按照步骤添加了库和其他文件，程序就ok了。

谢谢了。

回复 Fee Young:

可能是先后建立的时候有点差异。解决了就好。
