xcode中 有时候会报一个警告: 
[WARN]Warning: Multiple build commands for output file /xxx 

要解决这个问题很简单: 

1.选择你的工程 
2.选择target 
3.点击 Build Phases

在Keil MDK 里使用了C++，其中用到了基类和派生类。 编译的时候出现了大量warning:  #1300-D: XX_function  inherits implicit virtual 的警告信息。 由于对C++不熟，花了好半天时间去找消除警告信息的方法。 后面发现是这样的。 在基类中，定义了虚成员函数。如下： class Driver{ public: virtual ...
