Hey there,
I'm writing an app in C that requires MySQL interaction, so I downloaded the Connector/C archive from the official website, and it contains bin, lib and include folders, but I don't know where to install them.I could copy the include files into my project folder, but where can I put the lib file so that my compiled binary (and other binaries) can find it?
Thanks in advance!
答案：
the answer：
首先， 将 tar file，解压，然后：
其中位于lib 中的文件拷贝到 /usr/local/lib中
位于 include中的文件拷贝到 /usr/local/include中
位于bin中的文件拷贝到 /usr/local/bin 中；
注意： /usr/.. 文件夹可能时不可见的，所以，以上操作，要通通命令行来完成，祝你好运!
其次，在编译时，不要忘了链接库的选项：
方法1：采用动态链接库编译：
采用动态链接库的编译：最后附上一个编译代码操作：
gcc -o db.o db.c -lmysql
方法2: 采用静态库来编译： （生成的文件可能比较大，嘿嘿 ）
这个方法用动态连接库，比较那啥一点吧，看喜好，编译进去也行,2M多吧。
gcc -o db.o db.c /usr/local/lib/libmysqlclient.a
方法3： 将连接器转入你的工程中
在你没有进行以上操作时，你也可以通过以下方法通过编译： 通过指定链接库的路径
gcc -o db.o db.c -L mysql_connector_path/lib -l mysql
其中： mysql_connector_path 是你的mysql连接器所在的目录，通过 -L 选项来指定动态链接库的路径 ，这就是说通过在工程中包含该连接器目录，也能实现通过编译，更甚者把整个静态库都编译应用如方法2所采用的策略。

This is confusing, isn't it.. don't know why they don't make this more clear. The lib/ files go in /usr/local/libThe include/ files go in /usr/local/includeThe bin/ files go in /usr/local/bin The /usr/.. directory isn't visible through finder afaik so you have to go at it via commandline. Best of luck Also, in your Xcode project, make sure you add a Linked Library by going to your Target's settings, General, then adding Linked Library "libmysqlclient.dylib"
