解决方案

使用像自制程序或 MacPorts 使其相当直观，向前解决这个问题。从Oracle直接获得的MySQL的二进制分发以及与OS X捆绑在一起的MySQL的二进制分发没有开发头，其中 mysql.h 就是其中之一。

Homebrew会像这样修复它：

  brew install mysql 
  

MacPorts非常类似：

  sudo port install mysql 
  

这两个安装库，一个命令行客户端和关联这些库的开发标头。启用服务器是可选的。

另外，您可以获取源代码直接从苹果公司购买并安装它。

I tried several ideas ... none of them worked ... I'm just trying to install mysql2 as a gem. My mysql is working, but every time my system says, that mysql.h is missing ... Has someone an idea? It's very frustrating now ...

I'm using osx 10.8.3, ruby 1.9.3, rails 3.2.13 and home-brew.

    gem install mysql2 -v '0.3.11'
Building native extensions.  This could take a while...

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:
    --with-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib

    --curdir
    --ruby=/Users/gadreel/.rvm/rubies/ruby-1.9.3-p429/bin/ruby
    --with-mysql-config
    --without-mysql-config

    file `which mysql`
    /usr/local/mysql/bin/mysql: Mach-O 64-bit executable x86_64

解决方案

Using a package manager like Homebrew or MacPorts makes it fairly straight-forward to fix this. The binary distribution of MySQL direct from Oracle and the one bundled with OS X itself does not have the development headers, of which mysql.h is one of them.

Homebrew would fix it like this:

brew install mysql

MacPorts is very similar:

sudo port install mysql

Both of these install libraries, a command-line client and the associated development headers for the libraries. Enabling the server is optional.

As an alternative, you can get the source direct from Apple and install it whatever way you see fit.

Generally Homebrew is the best way to go.
