尝试安装MySQL对Rails的支持时出错

Question

Ruby version : 1.8.7 (2013-06-27 patchlevel 374) [x86_64-linux] Rails version : 2.3.5 OS: Cloud Linux 64 bit

I am trying to install mysql gem inorder to get support rails, the command is as follows,

gem install mysql -- --with-mysql-config=/usr/lib64/mysql/mysql_config

am getting the following error,

Building native extensions.  This could take a while...
ERROR:  Error installing mysql:
ERROR: Failed to build gem native extension.

/usr/local/rvm/rubies/ruby-1.8.7-p374/bin/ruby extconf.rb --with-mysql-                                config=/usr/lib64/mysql/mysql_config
extconf.rb:5: command not found: /usr/lib64/mysql/mysql_config --cflags
*** 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/local/rvm/rubies/ruby-1.8.7-p374/bin/ruby
    --with-mysql-config


Gem files will remain installed in /usr/local/rvm/gems/ruby-1.8.7-p374/gems/mysql-2.9.1 for inspection.
Results logged to /usr/local/rvm/gems/ruby-1.8.7-p374/gems/mysql-2.9.1/ext/mysql_api/gem_make.out

I even tried looking for mkmf.log, but cannot find it. I am trying to implement a RoR project, which already ran in Cent OS 5.9 64bit. This RoR is designed to be run in the above versions of Ruby & Rails, upgrading will create issues. Please help and direct me.

Seems like you are missing dev parts of libraries. Do you have libmysqlclient installed? What is the output of the locate command for the config file?

locate mysql_config
