rails ubuntu环境下mysql适配器安装

本机环境：ubuntu9.10  ruby1.87  rails 2.2.2  mysql 5.1        


       step 1:
          从http://www.tmtm.org/en/mysql/ruby/下载 mysql-ruby-2.X.tar.gz
     
       step 2:
           解压后，cd 到当前目录,运行 : ruby extconf.rb
           如果报错：
           no such file to load -- mkmf (LoadError)
           from extconf.rb:1
           则运行 ：sudo apt-get install ruby1.8-dev

       step 3:
           运行 :  ruby extconf.rb --with-mysql-dir=/usr/share/mysql(注：你本机mysql安装目录)
           如果报错：
           -----------------------------------------------------------------------------------------------------
           checking for mysql_query() in -lmysqlclient... no
           checking for main() in -lm... yes
           checking for mysql_query() in -lmysqlclient... no

*** 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
    --without-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib
    --with-make-prog
    --without-make-prog
    --srcdir=.
    --curdir
    --ruby=/usr/bin/ruby1.8
    --with-mysql-config
    --without-mysql-config
    --with-mysql-dir
    --with-mysql-include
    --without-mysql-include=${mysql-dir}/include
    --with-mysql-lib
    --without-mysql-lib=${mysql-dir}/lib
    --with-mysqlclientlib
    --without-mysqlclientlib
    --with-mlib
    --without-mlib
    --with-mysqlclientlib
    --without-mysqlclientlib
    --with-zlib
    --without-zlib
    --with-mysqlclientlib
    --without-mysqlclientlib
    --with-socketlib
    --without-socketlib
    --with-mysqlclientlib
    --without-mysqlclientlib
    --with-nsllib
    --without-nsllib
    --with-mysqlclientlib
    --without-mysqlclientlib
    --with-mygcclib
    --without-mygcclib
    --with-mysqlclientlib
    --without-mysqlclientlib
-----------------------------------------------------------------------------------------------------

则运行 ： sudo apt-get install libmysqlclient15-dev

step 4 :
      运行 : make

step 5 :
     运行 : make install


ps:上次用django开发，mysql这块也是配置了半天。哎，难怪用j2ee的人这么多，入门没这么烦。
