以前都是编译着玩，下载下来一个源码包编译试试，不行就拉到，也没有深入追究。
但是，这次因为工作需要必须要编译mysql++ API，我按照他们的说明编译的，但是不行，而且我机器上也有build-essential

编译列表的错误请看下面的回复帖子。大体情况是这样的。每次到make这一步的时候都会提示找不到makefile文件，不知道大家伙有没有遇到这种情况？

很急，请帮忙看看。谢谢拉

关键是这里没通过……

I can't help !

还未安装相关的依赖程序库！

在编译mysql++ API 前你装好了mysql没？

看清楚install 或 readme。你是打什么命令configure的？会不会要指定mysql库的位置？

你需要这个先，不然找不到库文件
libmysqlclient12-dev

谢谢xiaosir,已经ok了
