项目场景：

ROS编译报错

问题描述：

有的时候自己在ROS的框架下写代码会遇到如下的问题：

以前遇到这种问题基本上心里就觉得凉了，因为这种编译之后的运行报错不好定位位置，所以之前遇到这种问题都束手无策

原因分析：

楼主是在写一个文件读写时运行报的错误，因为提前有在VS里面提前写了一些程序，当楼主在VS运行的时候发现同样的代码在VS里运行同样也会报错，错误如下：

这个错误就很显然了，向量用的时候超出了索引的范围，这里就可以得到结论，在ROS中出现上述错误的原因，一般来说都是因为内存使用不当造成的，比如说数组、向量引用超出范围等等

解决方案：

debug的方法：
在不同的函数地方cout << “函数运行到某某位置了吗” << endl; 定位错误，然后解决就可以

careful~

PS：本文的目的主要是想说明这种错误出现的时候不要着急，如果是自己写的代码就不停的cout定位就好
PPS：如果是代码git下来编译运行报了这样的错误就很难找了
PPPS：如果有大佬知道更好的debug方法或者遇到这种错误时解决的方法欢迎大家评论区留言
