生成MySQL Python modu时出错

Question

我正在尝试为我的diskstation1511nas（intelatom，Linux 2.6嵌入式）构建一个pythonmysql驱动程序。我有MySQL-python-1.2.3。虽然MySQL安装在NAS上，但它没有包含mysql_config实用程序，因此编译了一个完整的MySQL安装。在

在尝试构建时，我收到以下错误消息（请参阅下面的详细信息）。 感谢任何帮助。在

我也有同样的错误。问题是它缺少一些头文件。一个快速的Google显示它需要python-dev，但它是针对默认Python（2.7）的。在Python2.6中，有一个包python2.6-dev。所以我们需要的是：

$ sudo apt-get install python2.6-dev
