MySQL嵌入式版本的小程序例子_MySQL

bitsCN.com MySQL嵌入式版本越来越式微了。碰巧有个小应用用到了它，顺便记录一下。
文档可以参考http://dev.mysql.com/doc/refman/5.6/en/libmysqld-example.html，看起来年久失修的样子，没法一看就懂。
希望下面这个简化的步骤可以起到点作用。
1. 下载代码并且进行版本编译。这个还比较简单，文档说的也很靠谱。
$ cmake . -DCMAKE_INSTALL_PREFIX=/home/mysql -DWITH_EMBEDDED_SERVER=1
$ make clean$ make -j 8
$ make install

2. 写个小程序
$ ls
GNUmakefile main.cc my.cnf
具体代码就看附件好了，其实很简单。
$ make

3. 安装好MySQL，初始化一下
$ cd /home/mysql
$ scripts/mysql_install_db --defaults-file=/home/mysql/my.cnf

4. 启动小程序
$ ./main
