R语言之安装RODBC错误信息configure: error: "ODBC headers sql.hand sqlext.h not found"

1.  场景描述

    R语言 3.2，  Ubuntu 15.10, 根据情况需要安装RODBC。 故执行命令:

install.packages('RODBC')
    报错信息如下： 
checking for memory.h... yes
checking for strings.h... yes
checking for inttypes.h... yes
checking for stdint.h... yes
checking for unistd.h... yes
checking sql.h usability... no

checking for sqlext.h... no
configure: error: "ODBC headers sql.h and sqlext.h not found"
ERROR: configuration failed for package ‘RODBC’
* removing ‘/home/bladestone/R/x86_64-pc-linux-gnu-library/3.2/RODBC’
Warning in install.packages :
  installation of package ‘RODBC’ had non-zero exit status
   核心的错误信息： 
error: "ODBC headers sql.h and sqlext.h not found"
2. 问题分析

     ODBC是什么？ ODBC是一套连接数据库的访问协议，如果有和它相关的内容没有找到或者有问题，是否可以定位为ODBC本身在当前主机上的驱动或者类库有问题？

3.   系统检查

      Ubuntu上的与ODBC相关的内容是unixODBC，故可以检查一下这问题

     执行命令：

dpkg -s unixODBC
dpkg -s unixODBC-dev
    结果发现， unixODBC已经安装，而dev版本未安装， 问题定位确认。

    那有同学就会问题了？ unixODBC不是已经安装了吗，为什么还需要dev版本呢？  一般而言，如果基于源代码包来编译进行安装的情况，都是需要一定的依赖包，也就说发布包是基于二进制和特定操作系统来生成的，但是由于操作系统以及依赖环境的差异性，顺利安装的概率优先，很多情况下都是缺少依赖就无法正确安装。 所以大部分情况下都是基于源代码来编译安装的，R这里就是这种情况。

   dev版本一般就是为了进行基于源代码编译然后安装的情况而生成的。

4.  问题解决

      安装依赖包

        sudo apt-get insall  unixODBC-dev

     安装RODBC

       install.packages('RODBC')

      安装结果信息：

5. R安装过程信息的分析

   经过观察可以发现，其中有checking,configure, gcc之类的中间信息出来，这些都是基于Linux的make命令而来的编译安装过程，基于这些信息，就基本可以确定这个是基于源代码来进行安装的。
